The BA546 is a monolithic power amplifier designed for use in portable radios, tape recorders and interphones. With a 6V power supply voltage, it has a rated output of 330mW into an 8Ωload (THD = 10), and a maximum output of 550mW. It comes in a compact 9-pin SIP package with no heatsink fins.

Features

1) High output. POUT = 330mW (VCC= 6V and an 8Ω load (THD = 10)). See Fig. 2.

2) Good low voltage characteristics. Begins operating at less than 2V (see Fig. 1).

3) 9-pin SIP package; around the same size as a preamplifier.

4) Pin compatible with the Rohm BA526 and BA527 power ICs. Choose to suit your application.

5) Low current dissipation (4.8mA Typ.).

Applications

Portable radios, cassette recorders, and interphones.
