This is a surplus Toshiba TA8264AH audio amplifier chip.
These chips are new but have been stored loose in bags/boxes.
Some of these parts have bent pins.
The TA8264AH is 4 channel BTL audio power amplifier for car audio applications.
This IC can generate more high power: POUTMAX = 41 W as it is included the pure complementary PNP and NPN transistor output stage.
It is designed low distortion ratio for 4 ch BTL audio power amplifier, built-in stand-by function, muting function, and a diagnosis circuit which can detect output to VCC/GND short and over voltage input mode.
Additionally, the AUX amplifier and various kind of protector for car audio use are built-in.
High power : POUTMAX (1) = 41 W (typ.)
(VCC = 14.4 V, f = 1 kHz, JEITA max, RL = 4 OHM)
: POUTMAX (2) = 37 W (typ.)
(VCC = 13.7 V, f = 1 kHz, JEITA max, RL = 4 OHM)
: POUT (1) = 24 W (typ.)
(VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 OHM)
: POUT (2) = 21 W (typ.)
(VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 OHM)
Built-in diagnosis circuit (pin 25)
Low distortion ratio: THD = 0.02% (typ.)
(VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 OHM)
Low noise: VNO = 0.18 mVrms (typ.)
(VCC = 13.2 V, Rg = 0 OHM, GV = 34dB, BW = 20 Hz~20 kHz)
Built-in stand-by switch function (pin 4)
Built-in muting function (pin 22)
Built-in AUX amplifier from single input to 2 channels
output (pin 16)
Built-in various protection circuit
: Thermal shut down, over voltage, out to GND, out to VCC, out to out short, speaker burned
Operating supply voltage: VCC (opr) = 9~18 VRead the complete TA8264AH specifications here.
These parts appear to be new but are loose packed so some of the pins may be slightly bent.
Parts will be shipped in ESD safe bag.
Each part weight is approximately 1/2 ounce.
