Synchronous demodulator

19 November 2014 Analogue, Mixed Signal, LSI

New from Analog Devices is the ADA2200 synchronous demodulator with integrated, configurable analog filter to enable designers of portable and low-power instrumentation to maximise battery life and perform precision magnitude and phase measurements on analog signals in the presence of large noise sources. Low-power (390 μA at 3,3 V and fCLK = 500 kHz) and rail-to-rail operation make the device ideal for advanced battery-powered and low-voltage systems serving medical, industrial and communications markets. Optimised for

input sampling rates up to 1 MHz, the ADA2200 enables demodulation of signal input bandwidths to 30 kHz, achieves 0,009° phase detection sensitivity and operates over a -40°C to +85°C temperature range.
