Mouser Electronics, Inc., the leading distributor in new product introductions (NPI), with the widest selection of semiconductors and electronic components, now has the AD8233 AFE (Analog Front End) for Analog Devices cardiac monitoring devices available.The AD8233 AFE is a fully integrated, single-electrode electrocardiograph (ECG) designed in a compact and user-friendly component. Low-power biopotential AFE enables smaller, lighter, and less intrusive cardiac monitoring devices with extended battery life. The highly integrated AD8233 AFE eliminates unnecessary costs and additional design time, helping developers achieve faster time to market.
The Analog Devices AD8233 AFE, available from Mouser Electronics, is an integrated signal conditioning block designed to extract, amplify, and filter small biopotential signals in noisy environments, such as those created by movement or remote electrode placement. This design allows for easy acquisition of the output signal by an ultra-low-power analog-to-digital converter (ADC) or embedded microcontroller.
The device's small footprint, 2.0 mm x 1.7 mm, allows designers to create smaller, lighter, and easier-to-use wearable healthcare devices. Along with its small size, the single-source (1.7 V to 3.5 V) AD8233 features an extremely low quiescent current of 50 μA (typical), resulting in extended battery life, which helps maintain continuous monitoring without the interruption of recharging or battery replacement.
For greater ease of use and flexibility, the AD8233 includes an integrated RLD (Right Leg Drive) amplifier with a turn-off function and a non-triggered operational amplifier. The device also provides an adjustable two-pole high-pass filter, an adjustable three-pole low-pass filter with adjustable gain, and a radio frequency interference (RFI) filter to enable consistent and reliable operation in adverse electrical environments across various use cases. The AD8233 is supported by the AD8233CB-EBZ evaluation board, a ready-to-use AFE tool with the necessary inputs, outputs, supplies, and cables routed to the test pins for simplified connectivity.
