AD9280ARSZ

AD9280 is a monolithic, single supply, 8bit, 32MSPS analogue-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference. The AD9280 uses a multistage differential pipeline architecture at 32MSPS data rates and guarantees no missing codes over the full operating temperature range. The input of the AD9280 has been designed to ease the development of both imaging and communications systems. The user can select a variety of input ranges and offsets and can drive the input either single-ended or differentially. The sample-and-hold amplifier (SHA) is equally suited for both multiplexed systems that switch full-scale voltage levels in successive channels and sampling single-channel inputs at frequencies up to and beyond the Nyquist rate. AC-coupled input signals can be shifted to a predetermined level, with an on-boardclamp circuit. The dynamic performance is excellent.
