Analog Devices’ Low Power AFE Enables Smaller, Lighter Wearable Health Devices with Longer Battery Life

Business Wire
Analog Devices, Inc. today announced a low power,
next-generation biopotential analog front end (AFE) which enables
smaller, lighter, and less obtrusive cardiac monitoring devices
with longer battery life. The AD8233 AFE is a fully integrated,
single-lead electrocardiogram (ECG) front end designed in one
compact, easy-to-use component. Typically, developers need to
design ECG front ends from individual components, which can add
incremental cost and design time. The highly integrated,
out-of-the-box AD8233 AFE eliminates these unnecessary costs and
extra time, helping developers get products to market more quickly.
Additionally, the device’s 2.0mm × 1.7mm tiny size enables the
design of wearable health devices that are smaller, lighter, and
easier to wear. Bulky, heavy, and obtrusive monitors can be
unpleasant for patients to wear and may even interfere with their
everyday lives. Longer battery life is another crucial attribute
for cardiac monitors and is vital to ensure continuous monitoring
that provides accurate data without the interruption of a recharge
or battery replacement. The AD8233 AFE’s low microamp-range power
consumption results in greatly extended battery life.

Along with its small size, the single-supply (1.7 V to 3.5 V)
AD8233 features extremely low quiescent current of 50 μA (typical);
lead on/off detection even while in shutdown mode (<1 μA); and
80-dB common-mode rejection ratio (DC to 60 Hz). Electrical noise,
a critical specification for cardiac-monitoring devices, is below
10 μV from 0.5 to 40 Hz. The AD8233 also allows for highly flexible
filter configurations which are essential to consistent, confident
operation in an inherently harsh electrical environment under a
range of use cases: a two-pole adjustable high-pass filter, a
three-pole adjustable low-pass filter with adjustable gain, and an
RFI filter. For ease-of-use and flexibility, it also includes an
integrated right leg drive (RLD) amplifier with shutdown plus an
uncommitted op amp. Analog Devices also offers an evaluation board,
reference design, web based filter design tool and Spice model to
facilitate design-in and speed time to market.
