APPLICATIONS • Down-hole Drilling • High Temperature Environments (1) Custom temperature ranges available DESCRIPTION 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 110 mW. The ADS8509 is available in a 28-pin SSOP package and is fully specified for operation from -40°C to 175°C. 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.
