The HI1175 is an 8-bit, analog-to-digital converter built in a 1.4m CMOS process. The low power, low differential gain and phase, high sampling rate, and single 5V supply make the HI1175 ideal for video and imaging applications.

The adoption of a 2-step flash architecture achieves low power consumption (60mW) at a maximum conversion speed of 20MSPS (Min), 35MSPS typical with only a 2.5 clock cycle data latency. The HI1175 also features digital output enable/disable and a built in voltage reference. The HI1175 can be configured to use the internal reference or an external reference if higher precision is required.
