Product Summary
The ADS7806U is a low-power 12-Bit sampling CMOS analog-to-digital converter. It contains a complete 12-bit, capacitor-based, SAR A/D with S/H, clock, reference, and microprocessor interface with parallel and serial output drivers. The ADS7806U can acquire and convert to full 12-bit accuracy in 25ms 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 ADS7806U is available in a plastic 0.3 DIP and in an SOIC, both fully specified for operation over the industrial –40℃ to +85℃ temperature range.
