Overview
The MAX194BEPE+ is a 14-bit successive-approximation analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This component is renowned for its high speed, high accuracy, and low power consumption. It features internal calibration circuitry that corrects linearity and offset errors, ensuring full rated performance over the operating temperature range without external adjustments. The MAX194BEPE+ uses a capacitive-DAC architecture, providing an inherent 85ksps track/hold function. It supports both unipolar (0V to VREF) and bipolar (-VREF to VREF) input ranges with an external reference up to +5V. Separate analog and digital supplies help minimize digital-noise coupling.
