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.
