® 78 OPS 6 A615 8 AD ADS7816 ADS 781 6 12-Bit High Speed Micro Power Sampling ANALOG-TO-DIGITAL CONVERTER FEATURES q 200kHz SAMPLING RATE q MICRO POWER: 1.9mW at 200kHz 150µW at 12.5kHz q POWER DOWN: 3µA Max q 8-PIN MINI-DIP, SOIC, AND MSOP q DIFFERENTIAL INPUT q SERIAL INTERFACE DESCRIPTION The ADS7816 is a 12-bit, 200kHz sampling analogto-digital converter. It features low power operation with automatic power down, a synchronous serial interface, and a differential input. The reference voltage can be varied from 100mV to 5V, with a corresponding resolution from 24µV to 1.22mV. Low power, automatic power down, and small size make the ADS7816 ideal for battery operated systems or for systems where a large number of signals must be acquired simultaneously. It is also ideal for remote and/or isolated data acquisition. The ADS7816 is available in an 8-pin plastic mini-DIP, an 8-lead SOIC, or an 8-lead MSOP package.
