ADS1292RIPBS

The ADS1292RIPBS is TI’s eight-channel, low-noise biopotential analog front-end (AFE) for EEG/ECG and other biosignals. It combines eight programmable-gain amplifiers with an 8-channel 24-bit delta-sigma ADC, plus on-chip reference, lead-off detection, and a right-leg drive. It uses a simple SPI-compatible digital interface, with programmable data rates and onboard digital filtering. The device delivers high dynamic range, low power, and easy PCB integration, making it suitable for portable medical monitors and research systems. The IPBS suffix indicates a Pb-free packaging option. For exact specs (supply voltage, input ranges, gains, data rates), consult the latest TI datasheet and evaluation module information.

ADS1292RIPBS Features:
- Two-channel, 24-bit delta-sigma ADC front-end for biopotentials (ECG/EEG/EMG)
- On-chip programmable gain amplifiers with selectable gain
- Integrated voltage reference and buffer
- Bias drive and right-leg drive (RLD) for improved common-mode rejection
- Lead-off detection and electrode impedance monitoring
- Programmable data rate with available digital filtering options
- SPI-compatible serial interface with data-ready (RDY) signal
- Low-noise, low-power operation; high-input-impedance front end
- Safe, integrated front-end suitable for medical/portable bio-signal systems
- Package: IPBS (compact, surface-mount)
Typical applications include portable/clinical ECG, EEG, and other biopotential recording systems.

- Pin count: 28 pins (package code IPBS corresponds to a 28‑pin small-outline package).
- Function: ADS1292RIPBS is an 8‑channel, 24‑bit delta‑sigma analog‑front‑end for biopotential signals (ECG/EEG). It provides eight differential input channels (AINP/AINN per channel), an SPI‑style serial interface (SCLK, DIN, DOUT, CS) for configuration and data readout, plus control pins (START, DRDY/CONV, RESET, PWDN). It also includes power/GND pins and features such as programmable data rate, internal/external reference options, bias drive, lead‑off detection, and other biopotential‑measurement peripherals.

Manufacturer: Analog Devices, Inc. (ADI).
Company type: American multinational semiconductor company that designs and manufactures analog, mixed-signal, and DSP integrated circuits for signal processing, instrumentation, and communications.

ADS1292RIPBS is a two-channel, 24-bit biopotential front-end (AFE) for EEG, ECG, EMG, ENG and other biosignals. Primary application areas:
- Portable/ambulatory medical devices and wearables for cardiac and neurophysiological monitoring
- Sleep diagnostics (polysomnography) and home health monitoring
- Laboratory/clinical research instrumentation for biopotential data acquisition
- Two-channel systems (e.g., two-lead ECG or EEG setups)
- Any biosignal sensing needing integrated PGA, lead-off detection, RLD and DSP filtering.

ADS1292RIPBS comes in a 28-pin VSSOP (Very Slim Small Outline) package.
