HMCAD1100

Analog To Digital Converters (ADC) Overview

The HMCAD1100 is an octal analog-to-digital converter featuring eight independent channels with a maximum sampling rate of 50 MSPS. It supports 12-bit and 14-bit output resolutions via serial LVDS interfaces. The device operates on a single 1.8V supply, consuming as low as 23 mW per channel at 20 MSPS. Key electrical specifications include a typical SNR of 72.2 dB at an 8 MHz input frequency, a differential input voltage range of 2 Vpp, and an input bandwidth of 500 MHz. Startup times are 15 µs from power down and 0.5 µs from sleep mode.

Analog To Digital Converters (ADC) FAQ

How does the HMCAD1100 handle data output resolution?

The device offers two serial LVDS output options: 12-bit and 14-bit. In 12-bit mode, the least significant bit is removed from the stream, while 14-bit mode adds a zero in the LSB position.

What is the startup time from power down mode?

The startup time from power down mode to active mode is typically 15 microseconds, allowing for rapid transitions in duty-cycled applications.

Can individual channels be powered down independently?

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