Overview
The MAX1127EGK+TD, produced by Analog Devices Inc./Maxim Integrated, is a quad, 12-bit analog-to-digital converter (ADC) optimized for low-power, high-dynamic performance. This ADC features fully differential inputs, a pipelined architecture, and digital error correction, making it suitable for demanding applications such as medical imaging, communications, and instrumentation. The MAX1127 operates from a 1.7V to 1.9V single supply, consuming only 563mW while delivering a 69.6dB signal-to-noise ratio (SNR) at a 19.3MHz input frequency. It also includes a power-down mode that reduces power consumption to 675µA during idle periods.
