The ADS7806UG4 is a 12-bit sampling Analog-to-digital Converter (ADC) using state of the art CMOS structures. The low-power ADC contains a complete 12-bit, capacitor-based, successive approximation register (SAR) A/D converter with sample-and-hold, clock, reference and a microprocessor interface with parallel and serial output drivers. The ADS7806 can acquire and convert to full 12-bit accuracy in 25us maximum, while consuming only 35mW maximum. Laser trimmed scaling resistors provide standard industrial input ranges of ±10V and 0 to 5V. In addition, a 0 to 4V range allows development of complete single-supply systems.
