ADS7807

S7807

SBAS022C – NOVEMBER 1992 – REVISED FEBRUARY 2006

Low-Power, 16-Bit, Sampling CMOS

ANALOG-to-DIGITAL CONVERTER

FEATURES

DESCRIPTION

ꢀ 35mW max POWER DISSIPATION

The ADS7807 is a low-power, 16-bit, sampling Analog-to-

Digital (A/D) converter using state-of-the-art CMOS struc-

tures. It contains a complete 16-bit, capacitor-based, Suc-

cessive Approximation Register (SAR) A/D converter with

sample-and-hold, clock, reference, and microprocessor inter-

face with parallel and serial output drivers.

ꢀ 50µW POWER-DOWN MODE

ꢀ 25µs max ACQUISITION AND CONVERSION

ꢀ ±1.5LSB max INL

ꢀ DNL: 16 bits “No Missing Codes”

ꢀ 86dB min SINAD WITH 1kHz INPUT

The ADS7807 can acquire and convert 16 bits to within

±1.5LSB in 25µs max while consuming only 35mW max.

Laser trimmed scaling resistors provide standard industrial

input ranges of ±10V and 0V to +5V. In addition, a 0V to +4V

range allows development of complete single-supply sys-

tems.

ꢀ ±10V, 0V TO +5V, AND 0V TO +4V INPUT RANGES

ꢀ SINGLE +5V SUPPLY OPERATION

ꢀ PARALLEL AND SERIAL DATA OUTPUT

ꢀ PIN-COMPATIBLE WITH THE 12-BIT ADS7806

ꢀ USES INTERNAL OR EXTERNAL REFERENCE

ꢀ 0.3" DIP-28 AND SO-28

The ADS7807 is available in a 0.3" DIP-28 and SO-28, both

fully specified for operation over the industrial –40°C to

+85°C temperature range.
