Overview
The AD5542ABCPZ-REEL7 is a 16-bit, serial-input, unbuffered voltage output digital-to-analog converter (DAC) produced by Analog Devices Inc. This component operates from a single supply voltage ranging from 2.7 V to 5.5 V and is available in a 10-lead and 16-lead LFCSP (Lead Frame Chip Scale Package) as well as a 16-lead TSSOP (Thin Shrink Small Outline Package). The DAC offers high precision with guaranteed monotonicity and 1 LSB INL (Integral Non-Linearity) accuracy over the full specified temperature range of −40°C to +85°C.
