TA8205AHQ,TA8205ALQ

18W BTL × 2CH Audio Power Amplifier

The thermal resistance θj−T of TA8205AHQ, TA8205ALQ

package designed for low thermal resistance, has a 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.

In addition, the functions of stand−by and muting, and a variety

of protection circuits are involved.

Features

• Low thermal resistance

: θj−T = 1.5°C / W (infinite heat sink)

• High power

: POUT (1) = 18W (typ.) / channel

Weight

HZIP17−P−2.00 : 9.8g (typ.)

HSIP17−P−2.00 : 9.8g (typ.)

(VCC = 14.4V, f = 1kHz, THD = 10%, RL = 4Ω)

POUT (2) = 15W (typ.) / channel

(VCC = 13.2V, f = 1kHz, THD = 10%, RL = 4Ω)

• 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 pin(4) set at low, power is turned off.) : ISB = 1µA (typ.)

• Built−in muting function (with pin(1) set at low, power is turned off.) : V (mute) = 1V (typ.)

• 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
