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.
