描述 Description

The ADS931 is a high-speed pipelined Analog-to-Digital (A/D) converter that is specified to operate from standard +5V or +3V power supplies. This converter includes a high bandwidth track/hold and an 8-bit quantizer. The perfor-mance is specified with a single-ended input range of 1V to 2V when operating off of a +3V supply. This device also allows for standard input ranges such as 2V to 4V or 2V to 3V, when operating on +5V supplies. The full scale input range is set by an external reference. The ADS931 employs digital error correction techniques to provide excellent differential linearity for demanding imaging applications. Its low distortion and high SNR give the extra margin needed for telecommunications, video and test instrumentation applications. The ADS931 is available in an SSOP-28 package.
