Overview
The MAX1446GHJ+ is a 10-bit, 60Msps analog-to-digital converter (ADC) produced by Analog Devices Inc./Maxim Integrated. This device is optimized for low-power, high dynamic performance applications, particularly in imaging and digital communications. It operates from a single 2.7V to 3.6V supply, consuming only 90mW while delivering a 59.5dB signal-to-noise ratio (SNR) at a 20MHz input frequency. The ADC features a fully differential input stage with a 400MHz, -3dB bandwidth and supports both differential and single-ended inputs. It also includes an internal 2.048V precision bandgap reference and offers a flexible reference structure for increased accuracy or different input voltage ranges.
