Low-power 4-channel ECG AFE with pacemaker, lead-off & lead quality detection, and FIFO

The AFE1594 is a family of multichannel,

simultaneous sampling, 24-bit, delta-sigma (ΔΣ) analog-to-digital converters (ADCs) with

built-in programmable gain Instrumentation Amplifiers (INAs), internal reference, and an

on-chip PLL. The AFE supports digital pace pulse detection, thoracic impedance measurement

and incorporates all of the features that are commonly required in medical electrocardiogram

(ECG) and electroencephalogram (EEG) applications. Multiple AFE159x devices can be cascaded

in high channel count systems. With high levels of integration and exceptional performance,

the AFE159x enables the development of scalable medical instrumentation systems at

significantly reduced size, power, and overall cost.
