TI ADS1294 / ADS1296 Analog Front End

Texas Instruments ADS1294 and ADS1296 low-power 24-bit analog front end devices for biopotential measurements feature high levels of integration and exceptional performance that enables the development of scalable medical instrumentation systems at significantly reduced size, power, and overall cost. TI ADS1294 and ADS1296 24-bit analog front end devices have a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature, and lead-off detection. The TI ADS1294 and ADS1296 operate at data rates as high as 32kSPS, allowing the implementation of software PACE detection. These TI analog front end delta-sigma analog to digital converters incorporate all of the features commonly required in medical ECG and EEG applications.
