Overview
The MAX1437ECQ+D, produced by Analog Devices Inc./Maxim Integrated, is an octal, 12-bit analog-to-digital converter (ADC) designed for high-dynamic performance and low power consumption. This ADC features a pipelined architecture and digital error correction, incorporating a fully differential signal path. It is optimized for applications in medical imaging instrumentation and digital communications. The device operates from a single 1.8V supply, consuming 768mW (96mW per channel), and delivers a 69.9dB signal-to-noise ratio (SNR) at a 5.3MHz input frequency. It also includes a power-down mode for idle periods to further reduce power consumption.
