ADS808

SBAS179C – DECEMBER 2000 – REVISED SEPTEMBER 2002

12-Bit, 70MHz Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● DYNAMIC RANGE:

SNR: 64dB at 10MHz f_IN

SFDR: 68dB at 10MHz f_IN

The ADS808 is a high-dynamic range, 12-bit, 70MHz,

pipelined Analog-to-Digital Converter (ADC). It includes a

high-bandwidth linear track-and-hold that has a low jitter of

only 0.25ps rms, leading to excellent SNR performance. The

clock input can accept a low-level differential sine wave or

square wave signal down to 0.5Vp-p, further improving the

SNR performance. It also accepts a single-ended clock

signal and has flexible threshold levels.

● PREMIUM TRACK-AND-HOLD:

Low Jitter: 0.25ps rms

Differential or Single-Ended Inputs

Selectable Full-Scale Input Range

● FLEXIBLE CLOCKING:

The ADS808 has a 2Vp-p differential input range (1Vp-p • 2

inputs) for optimum signal-to-noise ratio. The differential

operation gives the lowest even-order harmonic compo-

nents. A lower input voltage of 1.5Vp-p or 1Vp-p can also be

selected using the internal references, further optimizing

SFDR. Alternatively, a single-ended input range can be used

by tying the IN input to the common-mode voltage, if desired.

Differential or Single-Ended

Accepts Sine or Square Wave Clocking

Down to 0.5Vp-p

Variable Threshold Level

APPLICATIONS

● BASESTATION WIDEBAND RADIOS:

The ADS808 also provides an over-range flag that indicates

when the input signal has exceeded the converter’s full-scale

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

front-end signal conditioning circuitry. It also employs digital

error-correction techniques to provide excellent differential

linearity for demanding imaging applications. The ADS808 is

available in a small TQFP-48 PowerPAD™ thermally en-

hanced package.
