AD5426/AD5432/AD5443 are 8/10/12-bit high bandwidth serial interface multiplying DACs manufactured by Analog Devices
The AD5426, AD5432 and AD5443 are CMOS current‑output DACs available in 8‑, 10‑ and 12‑bit resolutions. They operate from a 3 V to 5.5 V supply, support a 10 V reference input, and provide up to 10 MHz multiplying bandwidth with low glitch energy.
The devices use a 3‑wire serial interface compatible with SPI, MICROWIRE and other DSP standards, include daisy‑chain and read‑back capabilities, and are offered in a 10‑lead MSOP package. Detailed specifications, timing characteristics, pin functions and ordering information are provided in the document.
