DESCRIPTION

range in between the 2Vp-p and 5Vp-p input ranges or to use

external reference. The ADS803 also provides an overrange indica-

tor flag to indicate an input range that exceeds the full-scale input

range of the converter. This flag can be used to reduce the gain of

the front end gain-ranging circuitry.

The ADS803 is a high-speed, high dynamic range, 12-bit pipelined

analog-to-digital converter. This converter includes a high-band-

width track/hold that gives excellent spurious performance up to

and beyond the Nyquist rate. This high-bandwidth, linear track/hold

minimizes harmonics and has low jitter, leading to excellent SNR

performance. The ADS803 is also pin-compatible with the 10MHz

ADS804 and the 20MHz ADS805.

The ADS803 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

communications, medical imaging, video and test instrumentation

applications. The ADS803 is available in 28-lead SSOP and SOIC

packages.

The ADS803 provides an internal reference and can be programmed

for a 2Vp-p input range for the best spurious performance and ease

of driving. Alternatively, the 5Vp-p input range can be used for the

lowest input referred noise of 0.09 LSBs rms giving superior

imaging performance. There is also a capability to set the input
