Overview
The MAX1231BETI+ is a 12-bit, 300ksps analogue-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This low-power, serial output, multichannel ADC features a fully differential, successive approximation register (SAR) conversion technique and an on-chip track and hold (T/H) block. It is designed for temperature control, process control, and monitoring applications, and it includes an internal temperature sensor and an internal reference. The device supports both single-ended and differential input configurations and operates from a supply voltage range of 2.7V to 3.6V. It is available in a 28-pin TQFN package with an exposed pad.
