TA8225H

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8225H,TA8225L TA8225H/L 45W BTL Audio Amplifier The TA8225H, TA8225L 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.)
