TA8201AK

TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8201AK BTL Audio Power Amplifier TA8201AK The TA8201AK is a audio power amplifier for consumer application. This IC is applying BTL system in which output coupling condenser and bootstrap condenser are not necessary and output 17W (VCC = 14.4V, BL =4Ω, THD = 10%) can be obtained. Since the package is a 7 pin SIP, (signal inline package), it greatly simplifies construction of a power amplifier both in design and assembly. It also contains various kind of protector. It is suitable for car−audio power amplifier with high performance. Features · High power: POUT (1) = 17W (typ.) (VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω) : POUT (2) = 14W (typ.) (VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω) · Very few external parts · Built in protector circuit Thermal shut down, over voltage protector (typ. VCC = 24V) ASO protector (RL short, Out to GND, Out to VCC) · 7 pin small package · Operating supply voltage range: VCC = 9~18V Weight: 2.19g (typ.) 1 2002-10-30 Block Diagram ＋ － Directions For Use And Application Method 1. Voltage gain adjustment TA8201AK This IC has the amplifier construction as shown in Fig.1. The pre-amp. Amp 1 is provided to the primary stage, and the input voltage is amplified by the flat amps, amp 3 and amp 4 of each channel through the phase amp. Amp 2. Since the input offset is prevented by pre-amp when VCC is set to on, this circuit can remarkable reduce the pop noise. The total closed loop gain ...
