MAX1280BEUP

Analog To Digital Converters (ADC) Overview

The MAX1280BEUP+ is a single-supply, low-power, 12-bit analog-to-digital converter (ADC) manufactured by Analog Devices / Maxim Integrated. It features an 8-channel multiplexer with a successive approximation register (SAR) architecture. The device supports sampling rates of up to 400 kSPS or 300 kSPS depending on the configuration. It integrates an internal 2.5V reference and communicates via a serial interface compatible with SPI/QSPI/Microwire standards. Housed in a 20-lead TSSOP package, it operates within a temperature range of -40°C to +85°C.
