Heart-rate monitor AFE

19 September 2012 Analogue, Mixed Signal, LSI

New from Analog Devices is the AD8232 single-lead heart-rate monitor analog front end (AFE) for a wide range of vital sign monitoring applications. In contrast to similar offerings, which are often derived from existing clinical cardiac monitor solutions, the new IC was designed specifically to meet the ECG signal conditioning requirements of emerging fitness, portable/wearable monitoring and remote health monitoring equipment. The highly flexible analog filtering configuration incorporates a two-pole, high-pass filter that is tightly coupled with the IC’s instrumentation amplifier architecture, and an uncommitted operational (gain) amplifier that enables the user to employ multi-pole low-pass filtering techniques to remove line noise and other interference.
