The ADS7807 is a low-power, 16-bit, sampling A/D using state-of-the-art CMOS structures. It contains a complete 16-bit, capacitor-based, SAR A/D with S/H, clock, reference, and microprocessor interface with parallel and serial output drivers. The ADS7807 can acquire and convert 16-bits to within 1.5LSB in 25s max while consuming only 35mW max. Laser-trimmed scaling resistors provide standard industrial input ranges of 10V and 0V to +5V. In addition, a 0V to +4V range allows development of complete single supply systems. The 28-pin ADS7807 is available in a plastic 0.3" DIP and in an SOIC, both fully specified for operation over the industrial 40C to +85C temperature range.
