AD5426/AD5432/AD5443 is a high bandwidth 8-bit, 10-bit and 12-bit multiplying DAC with serial interface
The AD5426, AD5432, and AD5443 are CMOS 8‑, 10‑, and 12‑bit current‑output digital‑to‑analog converters that operate from a 3 V to 5.5 V supply, making them suitable for portable and battery‑powered applications. They feature a 10 MHz multiplying bandwidth, 2.5 MSPS update rate, low glitch energy, and extended temperature operation from –40 °C to +125 °C.
The handbook includes detailed specifications, absolute maximum ratings, pin‑out diagrams, timing characteristics, typical performance graphs, and guidance on PCB layout, power‑supply decoupling, and evaluation‑board usage. It also provides an ordering guide and a comparison with other ADxx devices.
