DI CMOS ANALOG SWITCHES WITH DATA LATCHES

GENERAL DESCRIPTION The AD7590DI, AD7591DI and AD7592DI are a family of protected (latch-proof) dielectrically isolated CMOS switches featuring overvoltage protection up to ±25V above the power supplies. Microprocessor interfacing is facilitated by the provision of on-chip data latches.

Telephone Ringing Driver

Description The L7590C Telephone Ringing Driver produces a low-frequency sinusoidal ringing signal for analog telephone loops. This is accomplished by producing an output pulse stream that is an amplified replica of the digital input. The output is then filtered to produce a sine wave. The peak-t
