Overview
The MAX1446EHJ+ is a 10-bit, 60Msps (mega-samples per second) analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is designed for low-power, high dynamic performance applications, particularly in imaging and digital communications. It operates from a single 2.7V to 3.6V supply and consumes only 90mW of power while delivering a 59.5dB signal-to-noise ratio (SNR) at a 20MHz input frequency. The MAX1446EHJ+ features a fully differential input stage with a 400MHz, -3dB bandwidth and supports both differential and single-ended inputs.
