The AD5541/AD5542 are single, 16-bit, serial input, voltage output digital-to-analog converters (DACs) that operate from a single 2.7 V to 5.5 V supply. They feature full 16-bit performance, low power dissipation, fast settling time, unbuffered voltage output capable of driving 60 kΩ loads directly, etc.
The AD5541 and AD5542 are single‑channel, 16‑bit, voltage‑output digital‑to‑analog converters from Analog Devices that operate from a single 2.7 V to 5.5 V supply. They provide unbuffered outputs, low power dissipation (0.625 mW) and a 1 µs settling time.
The devices support SPI, QSPI and Microwire interfaces, can drive 60 kΩ loads directly, and feature low noise (11.8 nV/√Hz) and a glitch impulse of 1.1 nV·s. Typical applications include digital gain/offset adjustment, test equipment, data acquisition and industrial process control.
