What are the key features of PADS131M08IPBSR?
- 8-channel simultaneous sampling at 24-bit resolution and up to 32 kSPS per channel eliminates inter-channel phase skew in multi-sensor measurement systems
- Delta-sigma conversion architecture with ±1.2 V differential analog input range provides high accuracy for low-amplitude industrial sensor signals
- 32-pin LQFP package with SPI-compatible digital interface simplifies integration into existing microcontroller or FPGA-based data acquisition designs
What is PADS131M08IPBSR used for?
The PADS131M08IPBSR is designed for precision multi-channel data acquisition in vibration monitoring, power quality analysis, and industrial process control where all 8 channels must be sampled simultaneously at 24-bit resolution to eliminate phase errors between measurements. Its 32 kSPS per channel throughput and ±1.2 V input range make it well suited for condition monitoring systems, three-phase energy meters, and structural health monitoring nodes that require simultaneous high-resolution digitization across multiple sensor inputs.

Frequently Asked Questions
Why does simultaneous sampling matter for the PADS131M08IPBSR in vibration analysis systems?
The PADS131M08IPBSR samples all 8 channels simultaneously at up to 32 kSPS per channel, which means there is zero phase skew between any two channels. In vibration analysis, capturing 8 accelerometer signals without time offsets is essential for accurate phase difference calculations; a multiplexed ADC introduces inter-channel delays of tens of microseconds that distort frequency-domain results at frequencies above a few hundred Hz.
What analog input voltage range does the PADS131M08IPBSR accept, and how does this suit industrial sensor outputs?
The PADS131M08IPBSR accepts a differential analog input from -1.2 V to +1.2 V on each of its 8 channels. This ±1.2 V range matches the output of many low-voltage industrial sensors such as piezoelectric accelerometers, strain gauge bridges, and current transformers with signal conditioning stages, minimizing the gain required in front-end amplifier circuits and preserving the full 24-bit dynamic range.
What package does the PADS131M08IPBSR use, and what interface does it provide for connecting to a microcontroller?
The PADS131M08IPBSR is housed in a 32-pin LQFP (S-PQFP-G32) surface-mount package, which provides a compact footprint suitable for industrial PCBs. It communicates through an SPI-compatible serial interface, allowing straightforward connection to any microcontroller or FPGA with a standard 4-wire SPI port operating at typical clock rates of several MHz, and it outputs 24-bit binary data for all 8 channels.
