AD9280ARSZ

Product Summary

The AD9280ARSZ is a monolithic, single supply, 8-bit, 32 MSPS analog-to-digital converter with an on-chip sample-and-hold amplifier and voltage reference. The AD9280ARSZ uses a multistage differential pipeline architecture at 32 MSPS data rates and guarantees no missing codes over the full operating temperature range. The input of the AD9280ARSZ 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 onboard clamp circuit. The dynamic performance is excellent. The AD9280ARSZ has an onboard programmable reference. An external reference can also be chosen to suit the dc accuracy and temperature drift requirements of the application. The AD9280ARSZ can operate with a supply range from +2.7 V to +5.5 V, ideally suiting it for low power operation in high speed applications. The AD9280ARSZ is specified over the industrial (–40°C to +85°C) temperature range.
