ICmic IC MICROSYSTEMS ICM7363/7343/7323 QUAD 12/10/8-BIT VOLTAGE-OUTPUT DACS FEATURES 12/10/8-Bit Monotonic Quad DACs in 16 lead QSOP Package Wide Output Voltage Swing 150 µA per DAC at 5V Supply 100 µA per DAC at 3V Supply On Board Reference Three-wire SPI Interface Serial Data Out for Daisy-Chaining 8µs Full-Scale Settling Time APPLICATIONS Battery-Powered Applications Industrial Process Control Digital Gain and Offset Adjustment OVERVIEW The ICM7363, ICM7343 and ICM7323 are Quad 12-Bit, 10-Bit and 8-Bit wide output voltage swing DACs BLOCK DIAGRAM respectively, with guaranteed monotonic behavior. They include a 1.25V reference for ease of use and flexibility. The reference output is available on a separate pin and can be used to drive the reference input of each DAC. Alternately, each DAC can be driven by an external reference. There is a wide operating supply range of 2.7V to 5.5V. The input interface is an easy to use three-wire SPI/QSPI compatible interface. Each DAC can be individually controlled and has a double buffered digital input. There is a serial data output to allow for daisy-chaining applications.
