Description

M62353A is a CMOS structured semiconductor integrated circuit integrating 8 channels of built-in D/A converters with high performance buffer operational amplifier for each channel output.

The 3-wire serial interface (DI, CLK, LD) method is used for the transfer format of digital data to allow connection with microcomputer with minimum wiring. DO terminal is provided to allow cascading serial use.

Built-in buffer operational amplifiers are designed to operate or full swing in the whole voltage range from VCC to GND for each input/output. And their higher stability for capacitive load perfectly fits in to the use for electronic volume (VCA) or the replacement for semi-variable resistor for tuning.

Features

? 12-bit serial data input (3 wire serial data transfer method, DI, CLK, LD)

? Corresponds to TTL input for digital input (VINH ≥ 2 V, VINL ≤ 0.8 V)

? R-2R + segment method high performance 8ch 8-bit D/A converters

? 8ch buffer operational amplifiers operating in the whole voltage range from VCC to GND

? Buffer operational amplifiers with high oscillation stability for capacitive load

Application

Adjustment or control of industrial or home-use electronic equipments such as VTR camera, VTR set, TV, and CRT display.
