Product Summary
The ADS7807UB is a low-power, 16-bit, sampling Analog-to-Digital (A/D) converter using state-of-the-art CMOS structures. The ADS7807UB contains a complete 16-bit, capacitor-based, Successive Approximation Register (SAR) A/D converter with sample-and-hold, clock, reference, and microprocessor interface with parallel and serial output drivers. The ADS7807UB can acquire and convert 16-bits to within ±1.5LSB in 25μs 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.
