Texas Instruments  ADS8504IBDWR

The ADS8504 is a complete 12-bit sampling A/D converter using state-of-the-art CMOS structures. It contains a complete 12-bit, capacitor-based, SAR A/D with S/H, reference, clock, interface for microprocessor use, and 3-state output drivers.

The ADS8504 is specified at a 250-kHz sampling rate over the full temperature range. Precision resistors provide an industry standard ±10-V input range, while the innovative design allows operation from a single +5-V supply, with power dissipation under 100 mW.

The ADS8504 is available in a 28-pin SOIC package and is fully specified for operation over the industrial -40°C to 85°C temperature range.
