ANALOG DEVICES Quad, 12-Bit DAC Voltage Output with Readback DAC8412/DAC8413 FEATURES +5 to +15 Volt Operation Unipolar or Bipolar Operation True Voitage Output Double-Buffered Inputs Reset to Min or Center Scale Fast Bus Access Time Readback APPLICATIONS Automatic Test Equipment Digitally Controlled Calibration Servo Controls Process Control Equipment GENERAL DESCRIPTION The DAC-8412 and DAC-8413 are quad, 12-bit, voltage output DACs with readback capability. Built using a complementary BiCMOS process, these monolithic DACs offer the user very high package density. Output voltage swing is set by the two reference inputs Veery and Vegrpt- By setting the Vegr, input to 0 volts and Veery to a positive voltage, the DAC will provide a unipolar positive out- put range. A similar configuration with Vpgry at 0 volts and Veerrr at a negative voltage will provide a unipolar negative out- put range. Bipolar outputs are configured by connecting both Vrerrn and Vpgrz to nonzero voltages. This method of setting output voltage range has advantages over other bipolar offsetting methods because it is not dependent on internal and external resistors with different temperature coefficients. Digital controls allow the user to load or read back data from any DAC, load any DAC and transfer data.to all DACs at one time. An active low RESET loads all DAC output registers to mid- scale for the DAC-8412 and zero scale for the DAC-8413. The DAC-8412/DAC-8413 are available in 28-pin plastic DIP, cerdip, PLCC and LCC packages.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only and functional operation at or above this specification is not implied. Exposure to the above maximum rating conditions for extended periods may affect device reliability. 2. Digital inputs and outputs are protected, however, permanent damage may occur on unprotected units from high-energy electrostatic fields. Keep units in conductive foam or packaging at all times until ready to use. Use proper antistatic handling procedures. 3. Remove power before inserting or removing units from their sockets. 4. Analog outputs are protected from short circuit to ground or either supply.
