Overview
The MAX1420ECM+TD is a 12-bit, 60Msps (mega-samples per second), 3.3V low-power analog-to-digital converter (ADC) produced by Maxim Integrated, now part of Analog Devices Inc. This ADC features a fully-differential input, pipelined, 12-stage ADC architecture with wideband track-and-hold (T/H) and digital error correction. It is optimized for low-power, high dynamic performance applications in imaging and digital communications.
