TA8220HQ
30W BTL Ã 2ch Audio Power Amplifier
The thermal resistance θjâT of TA8220HQ 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
builtâin 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: θjâT = 1.5°C / W (infinite heat sink)
Weight: 9.8g (typ.)
⢠High power: POUT (1) = 30W (typ.) / channel
(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 2â¦)
: POUT (2) = 26W (typ.) / channel
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 2â¦)
: POUT (3) = 19W (typ.) / channel
(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4â¦)
⢠Low distortion ratio: THD = 0.04% (typ.)
(VCC = 13.2V, f = 1kHz, POUT = 1W, RL = 4â¦, GV = 50dB)
⢠Low noise: VNO = 0.30mVrms (typ.)
(VCC = 13.2V, RL = 4â¦, GV = 50dB, Rg = 0â¦, BW = 20Hz~20kHz)
⢠Builtâin standâby function (with (4)pin set at low, power is turned off.): ISB = 1µA (typ.)
⢠Builtâin output short detection circuit ((9)pin: Open collector)
⢠Builtâin output clip detection circuit ((1)pin: Open collector)
⢠Builtâin various protection circuits
Protection circuits: Thermal shut down, Over voltage, OutâVCC short, OutâGND short and OutâOut short.
⢠Operating supply voltage: VCC = 9~18V
