ADS1298CZXGR

The Texas Instruments ADS1298CZXGR is a high-performance Analog Front End (AFE) integrated circuit designed for demanding biopotential measurement applications. This device offers 8 channels, each with a 24-bit Analog-to-Digital Converter (ADC), providing exceptional resolution for capturing subtle physiological signals.

Key electrical specifications include an SPI-compatible serial interface for efficient data transfer and a wide operating supply voltage range of 2.7V to 5.5V. The AFE boasts low input-referred noise of 4 µV PP at 150 Hz bandwidth with a gain of 6, and a low input bias current of 200 pA, crucial for accurate biosignal acquisition. Data rates can range from 250 SPS up to 32 kSPS, with a Common Mode Rejection Ratio (CMRR) of -115 dB.

Packaged in a compact 64-NFBGA (8x8 mm) with surface mount capability, the ADS1298CZXGR is designed for space-constrained applications. Its integrated features, such as programmable gain amplifiers, lead-off detection, and pace detection, simplify system design for medical devices.

This AFE is well-suited for applications including 12-lead ECG, 18-lead ECG, AEDs, EEG, EMG, Holter monitors, portable telemetry, and telemedicine systems. It supports systems meeting critical medical standards like AAMI EC11, EC13, and IEC60601 series.
