Sanyo LC7536R Specifications

Ordering number : EN4863

O3194TH (OT) B8-1281 No. 4863-1/7

Overview

The LC7536R is an electronic volume control IC that
implements volume and balance functions with a
minimum number of external components.

Features

• The LC7536R is controlled by a 3-wire (DI, CL and CE)
serial data control scheme that can be shared with other
ICs. Up to two LC7536Rs can be used on the same bus
by using the S (select) pin.

• Eighty positions in 1 dB steps plus mute (–∞), maximum
attenuation is over 80 dB

• Input impedance (5 dB inputs): 47 kΩ (typical)

• High breakdown voltage: ±16 V
