CXA2500N Dual REC/PB Preamplifier

The CXA2500M/N is a dual recording/playback preamplifier system bipolar IC which has been developed for the low voltage operating cassette tape recorder. Features • Low quiescent current (VCC = 2V) PB: ICC = 3.2mA (typ.) REC: ICC = 5.2mA (typ.) • Very few external parts • Built-in Metal/Normal selection switch • Small switching noise due to internal transien.
