DESCRIPTION
The ADS8515 is a complete 16-bit sampling
analog-to-digital (A/D) converter using state-of-the-art
CMOS structures. It contains a complete 16-bit,
capacitor-based, SAR A/D converter with sample and
hold (S/H), reference, clock, interface for
microprocessor use, and 3-state output drivers.
The ADS8515 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 ADS8515 is available in a 28-pin SSOP package
and is fully specified for operation over the industrial
–40°C to 85°C temperature range.
