16-Bit 250-KSPS Sampling CMOS Analog-to-Digital Converter (Rev. B)
Texas Instruments

Description
The ADS8505 is a complete 16-bit sampling A/D converter using state-of-the-art CMOS structures. It contains a complete 16-bit, capacitor-based, SAR A/D with S/H, reference, clock, interface for microprocessor use, and 3-state output drivers. The ADS8505 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 ADS8505 is available in 28-pin SOIC and 28-pin SSOP packages, both fully specified for operation over the industrial -40C to 85C temperature range.
