ADS1298 Analog Front End

Texas Instruments ADS1298 Analog Front-End (AFE) devices for biopotential measurements features eight low-noise programmable gain amplifiers (PGAs) and eight high-resolution analog-to-digital converters (ADCs). These TI 24-bit ADCs with built-in PGAs incorporate all of the features commonly required in medical ECG and EEG applications. TI ADS1298 AFE 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. Multiple ADS1298 devices can be cascaded in high channel count systems in a daisy-chain configuration.
