Overview
The HMCAD1051-40 is a high-performance, ultra-low power analog-to-digital converter (ADC) produced by Analog Devices Inc. This single-channel ADC is designed for applications requiring high resolution and low power consumption. It features a proprietary structure that includes internal reference circuitry, a CMOS control interface, and CMOS output data. The ADC employs digital error correction to ensure no missing codes in the complete full-scale range and offers two idle modes—Standby Mode and Power Down mode—for optimized energy consumption during idle periods.
