3 Description

ADC12QJ1600-EP is a quad channel, 12-bit, 1.6

GSPS analog-to-digital converters (ADC). Low power

consumption, high sampling rate and 12-bit resolution

makes the device suited for a variety of multi-channel

communications systems.

Full-power input bandwidth (-3 dB) of 6 GHz enables

direct RF sampling of of L-band and S-band.
