The ADA2200 is a sampled analog technology1 synchronous demodulator for signal conditioning in industrial, medical, and communications applications. The ADA2200 is an analog input, sampled analog output device. 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. The ADA2200 includes an analog domain, low-pass decimation filter, a programmable infinite impulse response (IIR) filter, and a mixer. This combination of features reduces ADC sample rates and lowers the downstream digital signal processing requirements. 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.
