Please see the ADS8506 for an upgraded version of this device.
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.
The ADS7806 can acquire and convert to full 12-bit accuracy in 25us 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.
