ANALOG DEVICES BREAKS NEW GROUND FOR VITAL SIGN DETECTION AND PORTABILITY IN PATIENT MONITORING MEDICAL EQUIPMENT
Norwood, MA - Analog Devices Inc. continues its long history of serving the medical electronics industry by introducing the AD8220 JFET-input instrumentation amplifier. The AD8220 enhances the detection of patient vital signs in both fixed-line and transportable electrocardiograms (ECGs), electroencephalograms (EEGs) and other types of patient monitoring devices. Housed in an 8-lead plastic MSOP (mini-small-outline package) that is half the size of competing devices, the AD8220 in-amp allows designers of medical equipment to break new ground by freeing up additional board space to significantly increase ECG and EEG channel density, allowing for smaller medical monitoring systems. Monitoring equipment with high channel density also gives medical professionals more measurement points for very small signals like heart pulses and brain activity while protecting patient vital signs from electrical interference. In addition, the AD8220 operates on a single low-voltage power supply that draws only 700 µA, making it ideally suited for use in portable patient monitoring systems.

NEW 1 MHZ TO 10 GHZ LOG AMP EXTENDS RF POWER DETECTOR FAMILY
Norwood, MA - The AD8319, the latest addition to Analog Devices’ family of power detectors/controllers, accurately measures RF (radio frequency) signals over the industry’s widest frequency range of 1 MHz to 10 GHz, and delivers an exceptional combination of low power, small packaging and fast output response time. Offered at the lowest price point in the AD831x family, the AD8319 allows wireless designers to trade off dynamic range for system cost. The device supports all cellular standards (GSM, CDMA, W-CDMA and TD-SCDMA), broadband wireless standards (WiFi, WiMAX, WiBro), and proprietary systems that operate in a variety of frequency bands.

HIGH-SIDE MONITOR PRECISELY MIRRORS INPUT CURRENT OVER THE WIDEST RANGE FOR OPTICAL DESIGNS Norwood, MA - Analog Devices is introducing a high-side monitor that provides a compact solution for the common and often challenging problem of interfacing an optical power monitoring device, such as a logarithmic amplifier, to the cathode-side of a PIN photodiode. The ADL5315 mirrors the current at the cathode at a 1:1 ratio over a six-decade range, producing an output equal to the reference current monitored. Competing optical current monitors have much higher mirror ratios over narrower ranges, rendering proportional outputs at very low input currents impossible, while discrete solutions are more complex to implement and may require significantly more board space.
