It contains a complete 12-bit, capacitor-based SAR A/D with S/H, reference, clock, interface for microprocessor use, and three-state output drivers. The ADS7820 is specified at a 100kHz sampling rate, and guaranteed over the full temperature range. Laser- trimmed scaling resistors provide a 0 to +5V input range, with power dissipation under 100mW. The 28-pin ADS7820 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. 12-Bit 10 µs Sampling CMOS ANALOG-to-DIGITAL CONVERTER International Airport Industrial Park • Mailing Address: PO Box 11400 • Tucson, AZ 85734 • Street Address: 6730 S.
