MAX188DCPP

Analog To Digital Converters (ADC) Overview

The MAX188DCPP is a low-power, 8-channel, serial 12-bit Analog-to-Digital Converter (ADC) manufactured by Analog Devices Inc./Maxim Integrated. It utilizes a Successive Approximation Register (SAR) architecture to achieve a sampling rate of 133 kS/s. The device operates with a single supply voltage ranging from 2.7V to 5.5V and features an SPI-compatible serial interface for data output. Key electrical specifications include a signal-to-noise ratio (SNR) of 70 dB, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±0.75 LSB. It supports both differential and single-ended input configurations and requires an external reference voltage.
