Description
ADS8695IPWR is TI’s 16-bit, multi-channel SAR ADC. The IPWR suffix indicates the package with an exposed/power pad for better thermal performance. It provides eight analog inputs (single-ended or differential) that are multiplexed and converted to 16-bit digital data via a serial (SPI-like) interface. The device is aimed at precision data acquisition and instrumentation, offering high resolution with low noise and moderate power use. Typical applications include industrial sensing, lab instrumentation, and embedded multi-channel monitoring. It supports external references and configurable input ranges, with flexible timing and control via the serial interface. For exact performance—sampling rate, input voltage ranges, reference options, power rails, and package dimensions—refer to the TI ADS8695 datasheet and product page. If you’d like, I can pull out a concise spec sheet summary or compare it with related ADS869x parts.
Features
Here are typical features of the ADS8695IPWR (industrial-temp, IPWR package) variant:
- 16-bit resolution with high-accuracy ADC
- SPI-compatible serial interface for data transfer (MSB-first, configurable word length)
- Differential input with programmable gain; supports single-ended operation
- Internal reference option and/or external reference input
- Flexible input ranges to accommodate sensor signals
- Low-power operation with multiple power modes and a power-down/shutdown option
- Industrial temperature range (IPWR) with suitable packaging
- Small footprint/package with robust ESD protection
- Data-ready signaling and continuous conversion support (DMA-friendly or interrupt-driven)
Note: exact numbers (sampling rate, input ranges, and power specs) vary by revision; please consult the latest datasheet for precise parameters.
