HMCAD1040-40

Analog To Digital Converters (ADC) Overview

The HMCAD1040-40 is a dual-channel, high-performance, low-power analog-to-digital converter (ADC) manufactured by Analog Devices Inc. It features a 10-bit resolution with a maximum sampling rate of 40 MSPS and an internal reference circuitry. The device operates on a 1.8 V core supply voltage and supports I/O voltages from 1.7 V to 3.6 V. Key electrical specifications include a typical Signal-to-Noise Ratio (SNR) of 61.6 dB at 8 MHz input frequency, a total power dissipation of 24 mW at 20 MSPS and 43 mW at 40 MSPS, and an aperture jitter of less than 0.5 ps rms. It utilizes parallel CMOS outputs and is housed in a 9 x 9 mm 64-pin QFN package.
