ADS7806

SBAS021B – NOVEMBER 1992 – REVISED SEPTEMBER 2003

Low-Power 12-Bit Sampling CMOS

ANALOG-to-DIGITAL CONVERTER

FEATURES

DESCRIPTION

ꢀ POWER DISSIPATION: 35mW max

The ADS7806 is a low-power, 12-bit, sampling Analog-to-

Digital (A/D) converter using state of the art CMOS structures.

It contains a complete 12-bit, capacitor-based, Successive

Approximation Register (SAR) A/D converter with sample-

and-hold, clock, reference, and a microprocessor interface with

parallel and serial output drivers.

ꢀ POWER-DOWN MODE: 50µW

ꢀ ACQUISITION AND CONVERSION: 25µs max

ꢀ ±1/2 LSB MAX INL AND DNL

ꢀ 72dB MIN SINAD WITH 1kHz INPUT

ꢀ INPUT RANGES:

10V, 0V to +5V, and 0V TO +4V

The ADS7806 can acquire and convert to full 12-bit accuracy

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 systems.

ꢀ SINGLE +5V SUPPLY OPERATION

ꢀ PARALLEL AND SERIAL DATA OUTPUT

ꢀ PIN-COMPATIBLE WITH THE 16-BIT ADS7807

ꢀ USES INTERNAL OR EXTERNAL REFERENCE

ꢀ 0.3" DIP-28 AND SO-28

The ADS7806 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.
