DESCRIPTION
The ADS8519 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, successive approximation register
(SAR) A/D converter with sample-and-hold,
reference, clock, and a serial data interface. Data can
be output using the internal clock or synchronized to
an external data clock. The ADS8519 also provides
an output synchronization pulse for ease-of-use with
standard DSP processors.
The ADS8519 is specified at a 250kSPS sampling
rate over the full temperature range. Internal precision
resistors provide various input ranges including ±10V,
±5V, and 0V to 8.192V, while the innovative design
allows operation from a single 5V supply with power dissipation under 125mW.
The ADS8519 is available in a 28-pin SSOP
package, and is fully specified for operation over the industrial –40°C to +85°C temperature range.
