HMCAD1520TR

Analog To Digital Converters (ADC) Overview

The HMCAD1520 is a high-speed, low-power analog-to-digital converter featuring four independent channels with interleaving capabilities. It supports multi-mode operation including single channel (up to 1000 Msps), dual channel (up to 640 Msps), quad channel (up to 160 Msps), and precision mode (up to 105 Msps). The device offers configurable resolutions of 8-bit, 12-bit, or 14-bit. Key electrical parameters include a signal-to-noise ratio of up to 74 dB in precision mode and 70 dB in high-speed modes. Power dissipation is rated at 490 mW for the 12-bit 640 Msps configuration. It utilizes a serial LVDS output interface and operates on a 1.8 V supply voltage within a 7 x 7 mm 48-pin QFN package.
