The TA8225HQ, TA8225LQ 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 SW.
In addition, the functions of output short or over voltage detection and junction temperature are involved.
Features
• High power
: POUT (1) = 45W (typ.) (VCC = 14.4V, f = 1kHz, THD = 10%, RL = 2Ω)
: POUT (2) = 40W (typ.) (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 2Ω)
: POUT (3) = 24W (typ.) (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω)
• Low thermal resistance : θj−c = 1.5°C / W (infinite heat sink)
• Excellent output power band width : POUT (4) = 18W (typ.) (VCC = 13.2V, f = 50Hz~20kHz, THD = 1%, RL = 4Ω)
• Low distortion ratio : THD = 0.015% (typ.) (VCC = 13.2V, f = 1kHz, POUT = 4W, RL = 4Ω)
• Built−in stand−by function (with pin(1) set at high, power is turned on)
• Built−in output short or over voltage detection circuit, output to VCC and output to GND short. (Pin(8): Open collector)
• Built−in junction temperature detection circuit. (Pin(2): Open collector)
• Built−in various protection circuits
• Thermal shut down, Over voltage
• Output to GND short
• Output to VCC short
• Output to Output short
• Operating supply voltage: VCC (opr) = 9~18V
