MAX127BCAI

ADCs/DACs - Special Purpose Overview

The MAX127BCAI is a multirange, single-supply data acquisition system (DAS) featuring a 12-bit analog-to-digital converter and a 12-bit digital-to-analog converter. It operates from a +5V supply with a sampling rate of 8 kS/s. The device integrates an internal reference and utilizes a two-wire serial interface for communication. Key electrical specifications include a maximum power supply voltage of 5.27 V, a minimum of 4.75 V, and an integral nonlinearity (INL) of +/- 1 LSB. The signal-to-noise ratio is rated at 70 dB.
