BA5152F - 1.5V / 15mW dual power amplifier

Datasheet Summary

Description

(1) Power supply block The BA5152F has an internal power switch, so the VCC terminal (pin 9) connects directly to the power source.

Pin 13 is the power switch, and if it is left open, no bias current flows in the circuit and the IC will not operate.

Features

  • 1) High output. POUT = 15mW (RL = 16Ω). 2) Small “pop” noise. 3) Mute circuit terminal provided. 4) Terminals provided for radiation countermeasures. FBlock diagram 5) 6) 7) 8) Good ripple rejection ratio. Few external components required. Good low-voltage characteristics. Built-in power switch circuit.
