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 -40°C to 85°C temperature range.
