ADS7800

12-Bit 3µs Sampling

ANALOG-TO-DIGITAL CONVERTER

FEATURES

DESCRIPTION

● 333k SAMPLES PER SECOND

The ADS7800 is a complete 12-bit sampling analog-

to-digital converter using state-of-the-art CMOS struc-

tures. It contains a complete 12-bit successive ap-

proximation A/D converter with internal sample/hold,

reference, clock, digital interface for microprocessor

control, and three-state output drivers.

● STANDARD ±10V AND ±5V INPUT

RANGES

● DC PERFORMANCE OVER TEMP:

No Missing Codes

1/2LSB Integral Linearity Error

3/4LSB Differential Linearity Error

The ADS7800 is specified at a 333kHz sampling rate.

Conversion time is factory set for 2.70µs max over

temperature, and the high speed sampling input stage

insures a total acquisition and conversion time of 3µs

max over temperature. Precision, laser-trimmed scal-

ing resistors provide industry-standard input ranges of

±5V or ±10V.

● AC PERFORMANCE OVER TEMP:

72dB Signal-to-Noise Ratio

80dB Spurious-free Dynamic Range

–80dB Total Harmonic Distortion

● INTERNAL SAMPLE/HOLD, REFERENCE,

CLOCK, AND 3-STATE OUTPUTS

AC and DC performance are completely specified.

Two grades based on linearity and dynamic perform-

ance are available to provide the optimum price/

performance fit in a wide range of applications.

● POWER DISSIPATION: 215mW max

● PACKAGE: 24-Pin Single-wide DIP

24-Lead SOIC

The 24-pin ADS7800 is available in plastic and side-

braze hermetic 0.3" wide DIPs, and in an SOIC

package. It operates from a +5V supply and either a

–12V or –15V supply. The ADS7800 is available in

grades specified over 0°C to +70°C and –40°C to

+85°C temperature ranges.
