The HI1175 is an 8-bit, analog-to-digital converter built in a
1.4µm 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 ï¬ash architecture achieves low
power consumption (60mW) at a maximum conversion
speed of 20 MSPS (Min), 35 MSPS 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 conï¬gured to use the internal reference or an
external reference if higher precision is required.
