• Package: 20-pin DIP (Dual In-line Package)

Descriptions:

The LM1035N is designed for high-quality audio applications, providing independent control of bass, treble, balance, and volume through DC voltage inputs. It eliminates the need for bulky potentiometers and offers low distortion and noise performance.

Features:

• DC Control of Audio Functions (no moving parts)
• Wide Supply Voltage Range (9V to 16V)
• Low Distortion & Noise
• Independent Tone, Volume, and Balance Controls
• Compatible with Digital Control Systems

This IC is commonly used in car audio systems, home stereos, and other audio processing applications.
