TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8220H
30W BTL × 2ch Audio Power Amplifier
TA8220H
The thermal resistance θj−T of TA8220H package designed for
low thermal resistance, has high efficiency of heat radiation.
The temperature rise of chip can be reduced, and the influence
from the degradation of the features due to the temperature rise
at the high output can also be reduced.
This stereo audio power IC, designed for car audio use, has two
built−in channels to reduce the characteristic difference between
L and R channels. It also contains output short detection circuit,
output clip detection and various kind of protection.
Features
· Low thermal resistance: θj−T = 1.5°C / W (infinite heat sink)
· High power: POUT (1) = 30W (typ.) / channel
(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 2Ω)
: POUT (2) = 26W (typ.) / channel
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 2Ω)
: POUT (3) = 19W (typ.) / channel
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω)
Weight: 9.8g (typ.)
· Low distortion ratio: THD = 0.04% (typ.)
(VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4Ω, GV = 50dB)
· Low noise: VNO = 0.30mVrms (typ.)
(VCC = 13.2V, RL = 4Ω, GV = 50dB, Rg = 0Ω, BW = 20Hz~20kHz)
· Built−in stand−by function (with (4)pin set at low, power is turned off.): ISB = 1µA (typ.)
· Built−in output short detection circuit ((9)pin: Open collector)
· Built−in output clip detection circuit ((1)pin: Open collector)
· Built−in various protection circuits
Protection circuits: Thermal shut down, Over voltage, Out→VCC short, Out→GND short and Out−Out short.
· Operating supply voltage: VCC = 9~18V

5. Output clip detection function (pin(1))
The output clip detection terminal of pin(1) has the open collector output structure on clip as shown in Fig.5. In
case that the output waveform is clipping, the clip detection circuit is operated and NPN Tr. is turned on.
It is possible to improve the tone quality with the current of flowing into pin(1) and with controlling the volume,
tone･control circuit through L.P.F smoothing circuit as shown in Fig.5.
In case of being unused this function, use this IC as open connection on pin(1).
