The ADS8509IDW is a 16-bit successive-approximation register (SAR) analog-to-digital converter from Texas Instruments. It digitizes a single-ended analog input at a maximum sampling rate of 250 kSPS. The input voltage range is programmable from ±10 V down to ±3.3 V, making it suitable for a variety of signal conditioning applications. It uses a 5 V supply and supports both internal and external voltage references.
The device provides a SPI-compatible serial interface with a daisy-chain (TAG) feature, simplifying connection to microcontrollers and DSPs. The converter achieves a typical SNR of 88 dB and has a typical power consumption of 155 mW. It operates over the industrial temperature range of -40°C to 85°C and is available in a 20-SOIC surface-mount package.
Typical applications include industrial process control, data acquisition systems, digital signal processing, and medical instrumentation. The SAR architecture provides a good balance of speed and resolution for precision measurement systems.
