1 / 10 page ICM7562/7542/7522 Rev. A6 ICmic reserves the right to change specifications without prior notice 12/10/8-Bit Low Power Dual DACs With Serial Interface and Voltage Output FEATURES • 12/10/8-Bit Dual DAC in 08 Lead MSOP Package • Ultra-Low Power Consumption • Guaranteed Monotonic • Wide Output Voltage Swing • Three-wire SPI/QSP and Microwire Interface Compatible • Three Software-Selectable Power-Down Output Impedances (1 K Ohm, 100 K Ohm and Hi-Z) • Schmitt-Triggered Inputs for Direct Interfacing to Opto-couplers APPLICATION • Battery-Powered Applications • Industrial Process Control • Digital Gain and Offset Adjustment OVERVIEW The ICM7562, ICM7542 and ICM7522 are 12-Bit, 10-Bit and 8-Bit Voltage Output, Low Power, Dual DACs respectively, with guaranteed monotonic behavior. These DACs are available in 08 Lead MSOP package. They have three Software-Selectable Power-Down Output Impedances (1 K Ohm, 100 K Ohm and Hi-Z) as additional safety feature for applications that drive transducers or valves. 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 Schmitt- Triggered Inputs for Direct Interfacing to Opto-couplers easily.
