Description

The ADS7810 is a complete 12-bit sampling A/D using state-of-the-art CMOS structures. It contains a complete 12-bit capacitor-based SAR A/D with inherent S/H, reference, clock, interface for microprocessor use, and three-state output drivers.

The ADS7810 is specified at an 800kHz sampling rate, and guaranteed over the full temperature range. Laser-trimmed scaling resistors provide the industrystandard ±10V input range, while an innovative design allows operation from ±5V supplies.

The 28-pin ADS7810 is available in a plastic SOIC fully specified for operation over the industrial 40°C to +85°C range.
