ADS803

SBAS074B – JANUARY 1997 – REVISED SEPTEMBER 2002

12-Bit, 5MHz Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

APPLICATIONS

● HIGH SFDR: 82dB at NYQUIST

● HIGH SNR: 69dB

● LOW POWER: 115mW

● LOW DLE: 0.25LSB

● IF AND BASEBAND DIGITIZATION

● CCD IMAGING SCANNERS

● TEST INSTRUMENTATION

● FLEXIBLE INPUT RANGE

● OVER-RANGE INDICATOR

0.09LSBs rms giving superior imaging performance. There is

also a capability to set the input range in between the 2Vp-p

and 5Vp-p input ranges or to use an external reference. The

ADS803 also provides an over-range indicator 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.

DESCRIPTION

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

pipelined Analog-to-Digital (A/D) converter. This converter

includes a high-bandwidth track-and-hold that gives excel-

lent spurious performance up to and beyond the Nyquist rate.

This high-bandwidth, linear track-and-hold minimizes har-

monics and has low jitter, leading to excellent SNR perfor-

mance. 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 avail-

able in an SSOP-28 package.

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
