DESCRIPTION
The ADS7810 is a complete 12-bit sampling
analog-to-digital converter (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 3-state output drivers.
The ADS7810 is specified at an 800kHz sampling
rate, and ensured over the full temperature range.
Laser-trimmed scaling resistors provide the
industry-standard ±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 +70°C range.
