8-Bit, 20MSPS, Flash A/D Converter
Features
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.
• Resolution . . . . . . . . . . . . . . . . . . . . 8-Bit ±0.3 LSB (DNL)
• Maximum Sampling Frequency . . . . . . . . . . . . . .20MSPS
• Low Power Consumption . . . . . . . . . . . . . . . . . . . . .60mW
(Reference Current Excluded)
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.
