LOW VOLTAGE TELEPHONE SPEECH CIRCUITS

DESCRIPTION The L3281 is an electronic speech circuit developed to replace hybrid circuits in telephone sets that can be operated in parallel with other phones. ■ OPERATION DOWN TO 1.6V / 6.5mA ■ DTMF & BEEP TONE INPUTS ■ EXTERNAL MUTING FOR EARPHONE AND MICROPHONE ■ SUITABLE FOR DYNAMIC

CHOPPER-STABILIZED, PRECISION HALL-EFFECT LATCHES

The A3280--, A3281--, and A3283-- Hall-effect latches are ex tremely temperature-stable and stress-resistant sensors especially suited for operation over extended temperature ranges to +150°C. Superior high-temperature per for mance is made possible through dynamic offset cancellation, which reduc
