CXA2500M/N
Dual REC/PB Preamplifier
Description
The CXA2500M/N is a dual recording/playback pre-
amplifier system bipolar IC which has been developed
for the low voltage operating cassette tape recorder.
Features
Low quiescent current (V
CC
= 2V)
PB: I
CC
= 3.2mA (typ.)
REC: I
CC
= 5.2mA (typ.)
Very few external parts
Built-in Metal/Normal selection switch
Small switching noise due to internal transient
muting
Applications
3V headphone radio cassette recorders
Structure
Bipolar silicon monolithic IC
