OVERVIEW
The ICM7377B, ICM7357B and ICM7337B are Quad 12-
Bit, 10-Bit and 8-Bit wide output voltage swing DACs
respectively, with guaranteed monotonic behavior. These
DACs are available in 20 Lead QSOP package. They
include adjustable output gain for ease of use and
flexibility. The reference output is available on a separate
pin and can be used to drive external loads. The operating
supply range is 2.7V to 5.5V.
The input interface is an easy to use three-wire SPI/QSPI
and Microwire compatible interface. The DAC has a
double buffered digital input. And there is a serial data
output port to allow daisy-chaining applications.
