The ADS1291, ADS1292, and ADS1292R incorporate all features commonly required in a low-power medical electrocardiogram (ECG) application.
The ADS1291, ADS1292, and ADS1292R have a flexible input multiplexer per channel that can be independently connected to the internally-generated signals for test, temperature, and lead-off detection. Additionally, any configuration of input channels can be selected for derivation of the right leg drive (RLD) output signal. Lead-off detection can be implemented internal to the device, using the device internal excitation current sink or source. The ADS1292R version includes a fully integrated respiration impedance measurement function.
