Overview
The MAX1126EGK+D, produced by Analog Devices Inc./Maxim Integrated, is a quad, 12-bit analog-to-digital converter (ADC) designed for high-performance and 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 and consumes 563mW of power while delivering a 69.9dB signal-to-noise ratio (SNR) at a 5.3MHz input frequency. The MAX1126 also includes an 813µA power-down mode for idle periods, enhancing its energy efficiency.
