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.
