12-bit 2GSPS Time Interleaved ADC

The WEAADC12BHSI22G is a 12-bit time

interleaved Successive Approximation Analog-toDigital Converter (ADC) that supports both singleended and differential operation, depending on the

input and reference connections. It integrates 13

WEAADC12BHS22G with programmable clock

skew (50ps coarse 4ps fine with minimum step

0.25ps) and pre/post-calibration logic on each.

Operating on a 0.8 V power supply, the

WEAADC12BHSI22G can provide output up to

2GSPS in 13-interleaved mode. The ADC can be

clocked with 2GHz clock. Each ADC resolution is

programmable from 8 to 12 bits, as well as the

overall amount of interleaved instances
