TA8231LQ

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8231LQ 42W BTL × 2CH Audio Power IC TA8231LQ The TA8231LQ is BTL audio power amplifier for consumer application. It is designed for high power,low distortion and low noise. It contains various kind of protectors and the function of stand−by. Feature High power : POUT (1) = 42W (typ.) (VCC = 14.4V, f = 1kHz, THD = 10%, RL = 2Ω) : POUT (2) = 37W (typ.) Weight: 9.8g (typ.) (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 2Ω) : POUT (3) = 22W (typ.) (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω) Excellent output power bandwidth : POUT (4) = 17W (typ.) (VCC = 13.2V, f = 20Hz~20kHz, THD = 1%, RL = 4Ω) Fixed voltage gain : GV = 32dB (typ.) VCC = 13.2V, Vout = 0.775Vrms (0dBm) Low thermal resistance : θj−c = 1.5°C / W (typ.) Low distortion : THD = 0.02% (typ.) (VCC = 13.2V, f = 1kHz, Pout = 4W, RL = 4Ω) Built−in stand−by switch function : ISTBY = 100µA (typ.) (With pin(1) set at high, power is turned on) Built−in various protection circuit : Thermal shut down,Over voltage,Out to GND,Out to VCC,Out to Out short Operating supply voltage : VCC (opr) = 9~18V 1 2004-09-28 Block Diagram (GV = 32dB) TA8231LQ Caution And Application Method (Description is made only on the single channel.) 1. Voltage gain adjustment This IC has no NF (negative feedback) terminals. Therefore, the voltage gain can't adjusted, but it makes the device a space and total costs saver. The voltage gain is decided only ...
