Overview
The MAX1416EWE+ is a low-power, 2-channel, 16-bit analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device utilizes a sigma-delta modulator with a digital filter to achieve high resolution and accuracy. It is designed as a pin-compatible upgrade to the MX7705/AD7705 and features an internal oscillator, an on-chip input buffer, and a programmable gain amplifier (PGA). The MAX1416EWE+ supports SPI-, QSPI-, and MICROWIRE-compatible serial interfaces, making it versatile for various applications.
