ADC Single SAR 250ksps 16-bit Serial 28-Pin SSOP Tube, ADS8509IBDB, Texas Instruments

The ADS8509 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 ADS8509 also provides an output synchronization pulse for ease of use with standard DSP processors. The ADS8509 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. The ADS8509 is available in 20-pin SO and 28-pin SSOP packages, both fully specified for operation over the industrial –40°C to 85°C temperature range.
