DESCRIPTION

The ADS902 is a high speed pipelined Analog-to-Digital

Converter (ADC) that is specified to operate from a single

+5V supply. This converter includes a wide bandwidth

track/hold and a 10-bit quantizer. The performance is speci-

fied with a single-ended input range of 2.25V to 3.25V, or

2V to 4V. The input range is set by the external reference

values.

The ADS902 employs digital error correction techniques to

provide excellent differential linearity for demanding imag-

ing applications. Its low distortion and high SNR give the

extra margin needed for telecommunications, video and test

instrumentation applications. This high performance ADC is

specified to operate at a 30MHz sampling rate. The ADS902

is available in a SSOP-28 package.
