Overview
The MAX1416EPE+ is a 16-bit, low-power, 2-channel, sigma-delta analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is packaged in a 16-pin DIP and is designed to achieve high-resolution conversions with no missing codes. It features an internal oscillator, an on-chip input buffer, and a programmable gain amplifier (PGA) with gains ranging from 1 to 128. The MAX1416EPE+ is pin-compatible with the MX7705/AD7705, making it a suitable upgrade for existing designs.
