ICmic IC MICROSYSTEMS FEATURES • 12/10/8-Bit Monotonic Dual DACs in 10 lead MSOP Package • Wide Output Voltage Swing • 100 µA per DAC • On Board Reference • Serial Interface with three-wire SPI/QSPI and Microwire Interface Compatible • 8µs Full-Scale Settling Time APPLICATIONS • Battery-Powered Applications • Industrial Process Control • Digital Gain and Offset Adjustment OVERVIEW The ICM7362, ICM7342 and ICM7322 are Dual 12-Bit, 10Bit and 8-Bit wide output voltage swing DACs respectively, ICM7362/7342/7322 DUAL 12/10/8-BIT VOLTAGE-OUTPUT DACS 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. The operating supply range is 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.
