Description

The ADS7819 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 ADS7819 is specified at an 800kHz sampling rate, and guaranteed over the full temperature range. Laser-trimmed scaling resistors provide a ±2.5V input range and inherent overvoltage protection up to ±25V.

The 28-pin ADS7819 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 range.
