The ADS7806 is a low-power 12-bit sampling analog-to-digital using state-of-the-art CMOS structures. It contains a complete 12-bit, capacitor-based, SAR A/D with S/H, clock, reference, and microprocessor inter-face with parallel and serial output drivers.
The ADS7806 can acquire and convert to full 12-bit accuracy in 25s 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 28-pin ADS7806 is available in a plastic 0.3" DIP and in an SOIC, both fully specified for operation over the industrial 40°C to +85°C temperature range.
