MAX1303BEUP+

Analog To Digital Converters (ADC) Overview

The MAX1303BEUP+ is a 16-bit, four-channel successive-approximation analog-to-digital converter (ADC) operating from a single +5V supply. It achieves throughput rates up to 115ksps and features software-programmable input ranges for each channel. The device supports seven single-ended ranges and three differential ranges relative to the reference voltage. An internal +4.096V bandgap reference is available, or an external reference between 3.800V and 4.136V can be used. Digital interfacing is handled via an SPI-/QSPI-/MICROWIRE-compatible serial interface with a separate digital I/O supply ranging from 2.7V to 5.25V. The component is housed in a 20-pin TSSOP package.
