概要
Description
ADS114S08BIPBS is TI’s eight-channel, low-noise, high-resolution analog-front-end ADC designed for biomedical instrumentation (ECG, EEG, EMG). It combines an input multiplexer, programmable-gain amplifiers, a delta-sigma ADC, and a reference with a convenient SPI interface in a compact package (BIPBS variant).
Key points:
- 8 input channels with programmable gain per channel
- Integrated reference and SPI-compatible serial interface
- High-resolution conversion with multiple data-rate options
- Low power operation and suitable for single-supply biomedical systems
- Suitable for multi-lead biopotential monitoring and compact medical devices
- Package variant BIPBS refers to a specific TI package/PCB footprint used for this part
Why choose it:
- Reduces component count by integrating front-end and ADC
- Simplifies PCB design for biopotential applications
- TI support resources provide application notes and reference designs
For exact specs (gain ranges, data rates, power, timing, and pinout), consult the ADS114S08 datasheet and packaging guide for the BIPBS variant.
