Connections to the EVM module can be made using banana plugs for the power supply and output connections. The inputs accept standard RCA plugs. 2.1.1 2.1.2 Power Supply 1. Ensure that all external power sources are set to OFF. 2. Connect an external regulated power supply adjusted from 10 V to 26 V to the module VCC (J7) and GND (J8) banana jacks taking care to observe marked polarity. Evaluation Module Preparations 2.1.2.1 Inputs and Outputs 1. If connecting to a fully differential input or a grounded input (the shield of the RCA jack is GND), remove jumpers J9 and J10 from the EVM board. These are located next to the input jacks J1 and J2. If connecting to a floating source, like a portable CD player, install J9 and J10. After setting the J9 and J10 jumpers appropriately, connect the audio source to J1 (RIGHT) and J2 (LEFT). 2. Connect a speaker across ROUT+ (J6) and ROUT- (J5). Connect another speaker across LOUT+ (J3) and LOUT- (J4). 3. Install both gain jumpers GAIN0 (J12) and GAIN1 (J13). This sets the gain of the amplifier to the lowest level, 20 dB. 4. Remove the jumper at MSTR/SLV (J14). If only one EVM is evaluated, it must be configured as the master. If multiple EVMs are connected together using the SYNC output (TP2), the additional EVMs must be configured in the slave mode by installing the J14 jumper. 5. Remove the jumper (J11). This places the device in a latched mode when a short-circuit event occurs. 2.1.2.2 Control Inputs 1. SD: This terminal is active low. A low signal on the device terminal (< 0.8 V) shuts down the amplifier; a high signal (> 2 V) on the device terminal places the amplifier in the active state. Holding down switch S1 places the amplifier in the SHUTDOWN state. Releasing S1 returns the amplifier to the active state. 2. MUTE: This terminal is active high. A high signal (> 2 V) on this terminal immediately terminates audio playback through the speakers and the outputs stop switching; a low signal (< 0.8 V) enables the device. S2 on the EVM controls the state of the MUTE terminal. Holding down switch S2 places the amplifier in the MUTE state. Releasing S2 returns the amplifier to the active state. 3. GAIN0/GAIN1: Together, these terminals determine the gain of the amplifier. Refer to Table 1. Installing a jumper in J12 or J13 sets the respective terminal to GND. Removing the jumper sets the respective terminals to VREG (~4 V). Removing jumpers INCREASES the gain while installing jumpers DECREASES the gain. Logic levels are TTL compatible. 4. MSTR/SLV: This terminal is used with the SYNC (TP2) output to synchronize the switching frequencies of multiple EVMs. For example, with 2 EVMs, one would be configured as the MASTER by removing the J14 jumper. The other EVM would be configured as the SLAVE device by installing a SLOU179A - December 2005 - Revised May 2007 Submit Documentation Feedback TPA3100D2 Rev.A Audio Power Amplifier Evaluation Module With LC Filter 3 www.ti.com Operation jumper in the J14 location. Logic levels are TTL compatible. Table 1. Gain Settings GAIN0 (J12) (1) Amplifier Gain (dB) ON ON 20 ON OFF 26 OFF ON 32 OFF OFF 36 GAIN1 (1) (J13) (1) OFF = Jumper removed; ON = Jumper installed 2.1.2.3 Control Outputs 1. FAULT: This pin is a TTL compatible output for reporting a short-circuit fault on the output. If the outputs are shorted to GND, VCC, or to each other, this terminal goes high and remains high until one of the following operations is performed: power is cycled, SHUTDOWN is cycled, or MUTE is cycled. If jumper J11 is installed, the MUTE terminal is connected directly to the FAULT terminal and a short-circuit fault is automatically cleared when it occurs. 2.1.3 Power Up 1. Verify correct voltage and input polarity and turn the external power supplies on. The EVM should begin operation. 2. Adjust the input signal. 3. Adjust the control inputs to the desired settings. 4. If no sound is audible, check the position of the MSTR/SLV (J14) jumper. It should be removed if evaluating a single EVM. 5. Adjust the amplifier gain by installing/removing the gain jumpers, J12 and J13. 4 TPA3100D2 Rev.A Audio Power Amplifier Evaluation Module With LC Filter SLOU179A - December 2005 - Revised May 2007 Submit Documentation Feedback www.ti.com TPA3100D2 Rev.A EVM Schematic TPA3100D2 Rev.A EVM Schematic R1 100k C23 J11 R 7 20 TP1 FAULT C24 1.0 nF 1.0 nF 0.22mF 0.22mF 1mF C17 VCC C20 10mF C9 C8 1.0 1.0 mF mF L3 33mH S2 L4 33mH R2 100k S1 VREG J5 ROUT- J6 ROUT+ VCC C4 R 8 20 3 C3 C12 NC BSRN ROUTN ROUTP ROUTN BSRP ROUTP C18 PVCCR LINP PGNDR LINN VCLAMPR TPA3100D2 220mF C16 C21 GAIN0 PGNDL GAIN1 PGNDL MSTR/SLV PVCCL J8 GND 1mF VCLAMPL NC J10 1mF PGNDR 1.0mF 1.0mF J7 VCC NC PVCCR AGND C13 C14 J12 MUTE RINP 1.0mF LIN J2 NC 1.0mF SHUTDOWN RINN RIN FAULT NC C11 AVCC J9 1mF C15 1mF C5 NC VCC Connected at PowerPad and then to J8 with single point connection.

Mailing Address: Texas Instruments, Post Office Box 655303, Dallas, Texas 75265 Copyright (c) 2005, Texas Instruments Incorporated EVM WARNINGS AND RESTRICTIONS It is important to operate this EVM within the supply voltage range of -0.3 V to 30 V and input voltage range of -0.3 V to 4.5 V. Exceeding the specified input range may cause unexpected operation and/or irreversible damage to the EVM. If there are questions concerning the input range, please contact a TI field representative prior to connecting the input power. Applying loads outside of the specified output range may result in unintended operation and/or possible permanent damage to the EVM. Please consult the EVM User's Guide prior to connecting any load to the EVM output. If there is uncertainty as to the load specification, please contact a TI field representative. EVM WARNINGS AND RESTRICTIONS (continued) During normal operation, some circuit components may have case temperatures greater than 85C. The EVM is designed to operate properly with certain components above 85C as long as the input and output ranges are maintained. These components include but are not limited to linear regulators, switching transistors, pass transistors, and current sense resistors. These types of devices can be identified using the EVM schematic located in the EVM User's Guide. When placing measurement probes near these devices during operation, please be aware that these devices may be very warm to the touch.
