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 can be 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 250-kHz sampling rate over the full temperature range. Precision resistors provide various input ranges including 10 V and 0 V to 5 V, while the innovative design allows operation from a single 5-V supply with power dissipation under 100 mW.
