AD5424/AD5433/AD5445 are 8/10/12-bit, high bandwidth, multiplying DACs with parallel interface from Analog Devices. Features include 2.5 V to 5.5 V supply operation, fast parallel interface (17 ns write cycle), 10 MHz multiplying bandwidth, -10 V reference input, extended temperature range -40�C to +125�C, 20-lead TSSOP and chip scale (4 mm x 4 mm) packages, etc.
The AD5424, AD5433, and AD5445 are CMOS 8‑, 10‑, and 12‑bit current‑output digital‑to‑analog converters that operate from a 2.5 V to 5.5 V supply, making them suitable for portable, battery‑powered applications. They feature a fast parallel interface with a 17 ns write cycle, 10 MHz multiplying bandwidth, and a ±10 V reference input, while supporting an extended temperature range of –40 °C to +125 °C.
The document includes detailed specifications, functional block diagrams, pin‑out tables for TSSOP and LFCSP packages, absolute maximum ratings, ordering information, and mechanical dimensions. It also outlines recommended ESD precautions and provides an overview of related AD54xx devices.
