Overview
The MAX195, produced by Analog Devices Inc./Maxim Integrated, is a 16-bit successive-approximation analog-to-digital converter (ADC) that combines high speed, high accuracy, and low power consumption. It features a 10µA shutdown mode, making it highly efficient for various applications. The internal calibration circuitry corrects linearity and offset errors, ensuring full rated performance over the operating temperature range without external adjustments. The capacitive-DAC architecture provides an inherent 85ksps track/hold function. The MAX195 supports both unipolar (0V to VREF) and bipolar (-VREF to VREF) input ranges, selectable via a pin configuration. Separate analog and digital supplies minimize digital-noise coupling, enhancing overall performance.
