Description

The HI5675 is an 8-bit, analog-to-digital converter built in an advanced CMOS process. The low power, low differential gain and phase, high sampling rate, and single 5V supply make the HI5675 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 with only a 2.5 clock cycle data latency. The HI5675 also features digital output enable/disable and a built in voltage reference. The HI5675 can be configured to use the internal reference or an external reference if higher precision is required.
