TDA1074A Product details

Description

TDA1074A The TDA1074A is a monolithic integrated circuit designed for use as volume and tone control circuit in stereo amplifiers.This dual tandem potentiometer IC consists of two ganged pairs of electronic potentiometers with the eight inputs connected via impedance converters, and the four outputs driving individual operational amplifiers.The setting of each electronic potentiometer pair is controlled by an individual d.c.control voltage.The potentiometers operate by current division bet

Features

High impedance inputs to both ‘ends’ of each electronic potentiometer.
Ganged potentiometers track within 0,5 dB.
Electronic rejection of supply ripple.
Internally generated reference level available externally so that the control voltage can be made to swing positively and negatively around a well-defined 0 V level.
The operational amplifiers have push-pull outputs for wide voltage swing and low current consumption.
The operational amplifie.
