What are the key features of ADS1147IPWR?
- 16-bit delta-sigma ADC with up to 2000 SPS programmable data rate for flexible throughput-accuracy tradeoff
- Integrated low-noise programmable gain amplifier (PGA) with gains from 1 to 128 for direct sensor interface
- Built-in internal voltage reference (2.048V) eliminates need for external reference in cost-sensitive designs
- Low-power operation down to 150µA in single-cycle conversion mode, ideal for battery-powered applications
- SPI-compatible serial interface with daisy-chain support simplifies multi-ADC system design
What is ADS1147IPWR used for?
The ADS1147IPWR is widely used in precision sensor measurement systems such as temperature sensing with thermocouples, RTDs, and thermistors due to its integrated PGA and low noise performance. It is well suited for industrial process control, data acquisition modules, and portable medical diagnostic equipment requiring high-resolution, low-power analog front ends. The device also finds application in weigh scales, strain gauge bridges, and battery-powered field instruments where integration of reference and PGA reduces BOM cost and board area.
