ADS1298 Description

Short technical summary and product information.

The Texas Instruments ADS1298 is a high-performance 8-channel, 24-bit Analog-to-Digital Converter (ADC) designed for biopotential measurements, particularly in ECG applications. It features an integrated ECG front end, simplifying system design and reducing component count.

 

Key electrical specifications include a low power consumption of 0.75 mW/channel, low input-referred noise of 4 μV PP, and a low input bias current of 200 pA. The device supports data rates from 250 SPS to 32 kSPS and offers a Common-Mode Rejection Ratio (CMRR) of -115 dB. Programmable gain options range from 1 to 12.

 

The ADS1298 utilizes an SPI-compatible serial interface for communication. It supports unipolar or bipolar supplies with AVDD ranging from 2.7 V to 5.25 V and DVDD from 1.65 V to 3.6 V. The operating temperature range is -40°C to 85°C.

 

Available in TQFP (PAG) 64 and NFBGA (ZXG) 64 packages, the ADS1298 is suitable for surface mount applications. It supports systems meeting various medical standards including AAMI EC11, EC13, and IEC60601 series.
