AD9280 Datasheet PDF

●The AD9280ARSZ is a complete single-supply 8-bit CMOS Analog-to-digital Converter (ADC) with an on-chip sample-and-hold amplifier and voltage reference. The ADC uses multistage differential pipeline architecture at 32MSPS data rates and guarantees no missing codes over the full operating temperature range. The input of the ADC 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 board clamp circuit. An external reference can also be chosen to suit the DC accuracy and temperature drift requirements of the application.
