M62353AGP
8BIT 8CH D-A CONVERTER WITH BUFFER AMPLIFIERS
DESCRIPTION
M62353A is a CMOS structured semiconductor integrated ciruict integrating
8 channels of built-in D-A converters with high performance buffer operational
amplifier for each channel output.
3-wire serial interface (DI,CLK,LD) method is used for the taransfer 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≥ 2V, VINL≤ 0.8V)
R-2R+ segment method high performance 8 channel 8 bit D-A converters
8ch buffer operational amplifiers opperating 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.
