DESCRIPTION
The TS486/7 is a dual audio power amplifier capa-
ble of driving, in single-ended mode, either a 16 or
a 32Ω s tereo heads et.
Capable of d escen ding to lo w voltages, it d elivers
up t o 90mW per channel (into 16Ω loads) of c on-
tinuous average power with 0.3% THD+N in the
audio bandwitdth from a 5V power supply.
An externally-controlled standby mode reduces
the supply current to 10nA (typ.). The unity gain
stable TS486/7 can be configured by external
gain-setting resistors or used in a fixed gain ver-
sion.
APPLICATIONS
■Headphone Am plifier
■Mobile phone, PDA, compu ter motherboard
■High end TV, portable audio player

RIN1,2 Inverting input resistor which sets the closed loop gain in conjunction with RFEED. This resistor also
forms a high pass filter with CIN (fc = 1 / (2 x Pi x RIN x CIN)) . Not needed in fixed gain versions.
CIN1,2 Input coupling capacitor which blocks the DC voltage at the amplifier’s input terminal.
RFEED1,2 Feedback resistor which sets the closed loop gain in conjunction with RIN.
AV= Closed Loop Gain= -RFEED/RIN. Not needed in fixed gain versions.
CSSupply Bypass capacitor which provides power supply filtering.
CBBypass capacitor which provides half supply filtering.
COUT1,2 Output coupling capacitor which blocks the DC voltage at the load input terminal.
This capacitor also forms a high pass filter with RL (fc = 1 / (2 x Pi x RL x COUT)).

APPLICATION NOTE:
TS486/ 487 GE NERAL DES CRIPTION
TS486/487 is a family of dual audi o amplifiers able
to drive 16Ω or 32 Ω headsets. Working in the 2V to
5.5V supply voltage range, they deliver 100mW at
5V and 12mW at 2V in a 16Ω load. An internal
output current limitation, offers protection against
short-circuits at the output over a limited time
period.
Fixed gain versions of the TS486 and TS487
including the feedback resistor and the input
resistors are also proposed to reduce the number
of ex tern al par ts.
The TS486 and TS487 exhibit a low quiescent
current of typically 1.8mA, allowing usage in
portable applications.
The standby mode is selected using the
SHUTDOWN input. For TS486 (respectively
TS487), the device is in sleep mode when PIN 5 is
connecte d at GND (resp. VCC).
GAIN SETTING
The gain of each inverter amplifier of the TS486
and TS487 is set by the resistors RIN and RFEED.
GainLINEAR = -(RFEED/RIN)
GaindB = 20 Log(RFEED/RIN)
Fixed gain versions TS486-n and TS487-n
including RIN and RFEED are proposed to reduce
external parts.
LOW FREQUENCY ROLL-OFF WITH INPUT
CAPACITORS
The low roll-off frequency of the headphone
amplifiers depends on the input capacitors CIN1
and CIN2 and the input resistors RIN1 and RIN2.
The CIN capacitor i n series with the i nput resistor
RIN of the amplifier is equivalent to a first order
high pass filter.
Assum ing that Fmin is the lowest frequency to be
amplified (with a 3dB attenuation), the minimum
value of CIN is :
CIN > 1 / (2*π*Fmin*RIN )
The following curve gives directly the low
frequency roll-off versus the input capacitor CIN
TS486-TS487
28/31
and for various values of th e input resistor RIN .
The input resistance of the fixed gain version is
typicall y 20kΩ.
The f ollowing curve show s the limits of the roll off
frequency depending on the min. and max. values
of Rin:
LOW FREQUENCY ROLL OFF WITH OUTPUT
CAPACITORS
The DC vol tage on the outputs of the TS486/487
is blocked by the output capacitors COUT1 and
COUT2 . Each output capacitor COUT in s er ie s w ith
the resistance of the load RL is equivalent to a first
order high pass filter.
Assum ing that Fmin is the low est frequency to be
amplified (with a 3dB attenuation), the minimum
value of COUT is:
COUT > 1 / (2*π*Fmin*RL)
The following curve gives directly the low roll-off
frequen cy versus the output capacitor COUT in µF
and for the two t ypical 16Ω and 32Ω impedances :
DECOUP LING CAPA CITOR CB
The internal bias voltage at Vcc/2 is decoupled
with the external capacitor CB.
The TS486 and TS487 have a specified Power
Supply Rejection Ratio parameter with CB = 1µF.
A higher value of CB improves the PSRR, for
exa mple, a 4.7µF im proves the P S RR by 15dB at
200Hz (please, refer to fig. 76 "PSRR vs Bypass
Capacitor").
POP PRECAUTIONS
Generally headphones are connected using a
connector as a jack. To prevent a pop in the
headphon es when plugged i n the jack, a resistor
should be connected in parallel with each
headphone output. This allows the capacitors
Cout to be charged even when no headphone is
plugged.
A resistor o f 1 kΩ is high enough to be a negligible
load, and low enough to charge the capacitors
Cout in less than one second.
