The AD5426/AD5432/AD5443 are CMOS 8-, 10-, and 12-bit current output digital multiplying DACs with 50 MHz serial interface and 10 MHz multiplying bandwidth.
The AD5426, AD5432, and AD5443 are CMOS current output digital-to-analog converters (DACs) available in resolutions of 8, 10, and 12 bits, respectively. These devices operate from a 3.0 V to 5.5 V power supply and utilize a double buffered 3-wire serial interface compatible with SPI, QSPI, MICROWIRE, and most DSP standards.
Key features include a multiplying bandwidth of 10 MHz, low glitch energy less than 2 nV-s, and guaranteed monotonic performance across the extended temperature range of -40°C to +125°C. The devices support daisy-chain mode via an SDO pin for cascading multiple packages and offer a readback function to verify register contents.
