HMCAD1101

Analog To Digital Converters (ADC) Overview

The HMCAD1101 is an octal 13/12-bit analog-to-digital converter (ADC) with a maximum sampling rate of 65 MSPS. It features eight differential analog inputs and serial LVDS outputs in 12-bit or 14-bit formats. The device operates on a single 1.8V supply, consuming 51 mW per channel at full speed. Key electrical specifications include a signal-to-noise ratio (SNR) of 72.2 dBFS at an 8 MHz input frequency and a total power dissipation of 405 mW. The component supports internal offset correction, coarse and fine gain control, and multiple low-power sleep modes.

Analog To Digital Converters (ADC) FAQ

What output data formats does the HMCAD1101 support?

The device supports both 12-bit and 14-bit output formats via its serial LVDS interface.

How is the device initialized after power-up?

Correct startup initialization requires applying a reset cycle followed by a power-down cycle using either the dedicated pins or the serial interface.

Can individual channels be powered down?

Yes, each of the eight channels can be powered down independently through the serial control interface to save power.
