Specialized ICs

The AD8232ACPZ-RL is a single-lead, open-loop, bioelectrical impedance monitoring integrated circuit that can be used to assess the electrical properties of the human body. This IC is ideal for medical applications such as heart rate monitoring, respiration monitoring, and mental stress monitoring because it amplifies, filters and measures the electrical signal of the human body. The AD8232ACPZ-RL includes a low-noise front-end amplifier, a Sallen-Key bandpass filter, and a precision Rectified Average (RMS) signal conversion point for an output voltage waveform. It also provides high signal integrity, fast signal rise time, and low-power operation.

Application Field

The AD8232ACPZ-RL is a single-lead, open-loop, bioelectrical impedance monitoring IC ideal for medical applications such as heart rate monitoring, respiration monitoring, and mental stress monitoring. It is designed for use in wearable medical devices where size and low power are important design considerations.

The AD8232ACPZ-RL is also well-suited for ambulatory applications such as cardiac monitoring in hospitals, rehabilitation centers, and nursing homes. The relatively small size of the IC (smaller than many microcontrollers) allows for integration into small, lightweight form factors. It is also suitable for home-based cardiac monitoring applications.

Working Principle

The AD8232ACPZ-RL integrates a low-noise, low-power amplifier, a bandpass filter, and a precision rectified average (RMS) signal conversion point for an output voltage waveform. The amplitude and other characteristics of the waveform output depend on bioelectrical impedance and input impedance of the device.

The low-noise front-end amplifier has two input differential pairs for two electrodes. The amplifier has two gain settings for two operating ranges. It amplifies the ECG/bioelectrical signal so it can be accurately monitored and measured.

The Sallen-Key bandpass filter is used to filter out noise and other unwanted signals, while the precision rectified average (RMS) signal conversion point produces an output voltage waveform, whose amplitude and other characteristics are dependent on the bioelectrical impedance and input impedance of the device.

The AD8232ACPZ-RL also includes an ESD protection diode for the input differential to ensure ESD robustness. The diode also serves to protect against large common-mode voltages on the input, keeping the electronics from being damaged.

The AD8232ACPZ-RL is a highly versatile and efficient integrated circuit for use in medical applications requiring an ECG tracking system. The IC operates on a single supply voltage, features low-power and high signal integrity, can be easily interfaced with digital and analog electronic devices, and provides an accurate and reliable measurement of bioelectrical signals.
