Overview
The MAX195BCPE+ is a 16-bit successive-approximation analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This high-speed ADC combines high accuracy, low power consumption, and a 10µA shutdown mode. It features internal calibration circuitry that 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 MAX195BCPE+ supports both unipolar (0V to VREF) and bipolar (-VREF to VREF) input ranges and is available in a 16-pin DIP package.
