General Description

is made only on the single channel) 1.

Voltage gain adjustment This IC has no NF (negative feedback) terminals.

Therefore, the voltage gain can't adjusted, but it makes the device a space and total costs saver.

Overview

TA8259H TOSHIBA Bipolar Linear Integrated Circuit Silicon Monolithic TA8259H Max Power 37 W BTL × 4CH Audio Power IC The TA8259H is 4 ch BTL audio power amplifier for car audio application.

This IC can generate more high power: POUT MAX = 37 W as it is included the pure complementary PNP and NPN transistor output stage.

It is designed low distortion ratio for 4 ch BTL audio power amplifier, built-in Stand-by Function, Muting Function, Clip detector, and diagnosis circuit.

Key Features

  • High power : POUT MAX (1) = 37 W (typ. ) (VCC = 14.4 V, JEITA max, RL = 4 Ω) : POUT MAX (2) = 35 W (typ. ) (VCC = 13.7 V, JEITA max, RL = 4 Ω) : POUT (1) = 24 W (typ. ) (VCC = 14.4 V, f = 1 kHz, THD = 10%, RL = 4 Ω) : POUT (2) = 21 W (typ. ) (VCC = 13.2 V, f = 1 kHz, THD = 10%, RL = 4 Ω).
  • Built-in clip detector & diagnosis circuit. (pin 25) Low distortion ratio : THD = 0.02% (typ. ) (VCC = 13.2 V, f = 1 kHz, POUT = 5 W, RL = 4 Ω).
  • Low noise : VNO = 0.16 mVrms (typ. ) (VCC = 13.2.
