TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic
TA8233BHQ
30W BTL × 2ch Audio Power Amplifier
The thermal resistance θjT of TA8233BHQ 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
builtin 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
High power
: POUT (1) = 30W (typ.) / channel
(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 2)
POUT (2) = 26W (typ.) / channel
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 2)
POUT (3) = 19W (typ.) / channel
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4)
Low thermal resistance: θjT = 1.5°C / W (infinite heat sink)
Low distortion ratio: THD = 0.04% (typ.)
(VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4, GV = 50dB)
Low noise: VNO = 0.30mVrms (typ.)
(VCC = 13.2V, RL = 4, GV = 50dB, Rg = 0, BW = 20Hz~20kHz)
Builtin standby function
: (with pin(4) set at low, power is turned off.) ISB = 1A (typ.)
Builtin output clip detection circuit
: (pin(1): Open collector (active low))
Builtin output short detection circuit
: (pin(9): Open collector (active low))
Builtin various protection circuits
: Thermal shut down, Over voltage, Out→VCC short, Out→GND short and OutOut short.
Operating supply voltage: VCC (opr) = 9~18V
Weight: 9.8g (typ.)
