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.
