The AD5425 is an 8-bit, high bandwidth, multiplying DAC with a serial interface. Its features include 2.5V to 5.5V supply operation, 50MHz serial interface, 9.5MSPS update rate, ±0.25LSB INL, ±10V reference input, etc.
The AD5425 is a CMOS 8‑bit current‑output DAC that operates from a 2.5 V to 5.5 V supply, making it suitable for portable, battery‑powered applications. It features a double‑buffered 3‑wire serial interface compatible with SPI, QSPI, MICROWIRE and most DSP standards, and includes an LDAC pin for simultaneous updates in multi‑DAC configurations.
The device offers a 10 MHz multiplying bandwidth, guaranteed monotonicity, and a wide temperature range of –40 °C to +125 °C. It is supplied in a 10‑lead MSOP package and provides a +10 V reference input, low glitch energy (<2 nV‑s) and typical power consumption of 0.4 pA.
