ADS7807

SBAS022B – NOVEMBER 1992 – REVISED SEPTEMBER 2003

Low-Power, 16-Bit, Sampling CMOS ANALOG-to-DIGITAL CONVERTER

FEATURES DESCRIPTION 35m W 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-

50µW POWER-DOWN MODE

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

25µs max ACQUISITION AND CONVERSION

cessive Approximation Register (SAR) A/D converter with

±1.5LSB max INL

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

DNL: 16 bits “No Missing Codes” face with parallel and serial output drivers. 86d B min SINAD WITH 1k Hz INPUT The ADS7807 can acquire and convert 16-bits to within

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

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

Laser trimmed scaling resistors provide standard industrial

SINGLE +5V SUPPLY OPERATION

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

PARALLEL AND SERIAL DATA OUTPUT

range allows development of complete single-supply sys-

PIN-COMPATIBLE WITH THE 12-BIT ADS7806 tems. USES INTERNAL OR EXTERNAL REFERENCE The ADS7807 is available in a 0.3" DIP-28 and SO-28, both

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

0.3" DIP-28 AND SO-28

+85°C temperature range.
