The ADA2200 is a synchronous demodulator and configurable analog filter designed to perform precision magnitude and phase measurements in low power, sensor signal conditioning and data acquisition applications for the industrial, medical, and communications markets. Implemented with ADI?s patent pending sampled analog technology (SAT), the ADA2200 is an analog input, sampled analog output device that includes an analog domain, low-pass 1/8x decimation finite impulse response (FIR) filter, a configurable infinite impulse response (IIR) filter, mixer with 0?/90? phase selection, reference clock and ADC driver output. Utilizing sampled analog technology, the signal processing is performed entirely in the analog domain by charge sharing among capacitors, which eliminates the effects of quantization noise and rounding errors and reduces downstream ADC sample rates while also offloading computationally heavy tasks from the digital processor or micro-controller.The ADA2200 acts as a precision filter when the demodulation function is disabled. The filter has a programmable bandwidth and tunable center frequency. The filter characteristics are highly stable over temperature, supply, and process variation.Single-ended and differential signal interfaces are possible on both input and output terminals, simplifying the connection to other components of the signal chain. The low power consumption and rail-to-rail operation is ideal for battery-powered and low voltage systems.The ADA2200 can be programmed over its SPI-compatible serial port or can automatically boot from the EEPROM through its I2C interface. On-chip clock generation produces a mixing signal with a programmable frequency and phase. In addition, the ADA2200 synchronization output signal eases interfacing to other sampled systems, such as data converters and multiplexers.The ADA2200 is available in a 16-lead TSSOP package. Its performance is specified over the industrial temperature range of ?40?C to +85?C. Note that throughout this data sheet, multifunction pins, such as SCLK/SCL, are referred to either by the entire pin name or by a single function of the pin, for example, SCLK, when only that function is relevant.Applications Synchronous demodulation Sensor signal conditioning Lock-in amplifiers Phase detectors Precision tunable Filters Signal recovery Control systems
