The AD9254 is a monolithic, single 1.8 V supply, 14-bit, 150 MSPS
analog-to-digital converter (ADC), featuring a high performance
sample-and-hold amplifier (SHA) and on-chip voltage reference.
The product uses a multistage differential pipeline architecture
with output error correction logic to provide 14-bit accuracy at
150 MSPS data rates and guarantees no missing codes over the
full operating temperature range.
The wide bandwidth, truly differential SHA allows a variety of
user-selectable input ranges and offsets, including single-ended
applications. It is suitable for multiplexed systems that switch
full-scale voltage levels in successive channels and for sampling
single-channel inputs at frequencies well beyond the Nyquist rate.
Combined with power and cost savings over previously available
ADCs, the AD9254 is suitable for applications in communications,
imaging, and medical ultrasound.
A differential clock input controls all internal conversion cycles. …
