Overview
The MAX1127EGK+D, produced by Analog Devices Inc./Maxim Integrated, is a quad, 12-bit analog-to-digital converter (ADC) designed for high-performance, low-power applications. This ADC features a pipelined architecture and digital error correction, making it ideal for medical imaging, communications, and instrumentation. It operates from a single 1.7V to 1.9V supply, consuming only 563mW while delivering a 69.6dB signal-to-noise ratio (SNR) at a 19.3MHz input frequency. The MAX1127 also includes a power-down mode that reduces power consumption to 675µA, enhancing its suitability for battery-powered devices.
