BA3812L

Audio Special Purpose Overview

The BA3812L is a five-point graphic equalizer integrated circuit manufactured by Rohm Semiconductor. It integrates five tone control circuits with input and output buffer amplifiers on a single chip, minimizing external component requirements. The device operates within a wide supply voltage range of 3.5V to 16V and draws a typical current of 5 mA. It features low distortion, low noise, and a wide dynamic range (VOM = 2.1Vrms at VCC = 8V). Packaged in an 18-ZIP (SSIP) through-hole format.
