ICM7377B/7357B/7337B

Quad 12/10/8-Bit Voltage Output DACs

with Serial Interface and Adjustable Output Gain

IC MICROSYSTEMS

FEATURES

OVERVIEW

•

12/10/8-Bit Monotonic Quad DAC in 20 Lead

QSOP Package

Adjustable Output Gain

Wide Output Voltage Swing

150 µA per DAC at 5V Supply

100 µA per DAC at 3V Supply

On Board Reference

Serial Interface with three-wire SPI/QSPI and

Microwire Interface Compatible

Serial Data Out for Daisy-Chaining

8 µS Full scale Settling Time

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.
