DESCRIPTION

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 sampleand-

hold, clock, reference, and a microprocessor interface with

parallel and serial output drivers.

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.

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.
