LM1036MX/NOPB

Audio Special Purpose Overview

The LM1036MX/NOPB is a dual DC-operated tone, volume, and balance circuit designed for stereo audio applications. It operates on a supply voltage range of 9V to 16V with a typical supply current of 45mA. The device provides a typical volume control range of 75dB and channel separation of 75dB. Total harmonic distortion is typically 0.06% at an input level of 0.3 Vrms. Tone control ranges are ±15dB typical, adjustable via external capacitors. It features a built-in zener regulated output at pin 17 (5.4V) for biasing control potentiometers. The component is housed in a 20-SOIC package.
