AD210AN Functional Block Diagram
Figure 1 depicts below the AD210AN basic block diagram. A +15 V supply is connected to the power port, and a 50 kHz carrier frequency supplies 15 V isolated power to both the input and output ports. The uncommitted input amplifier can provide gain or buffer to the AD210AN. The full-wave modulator converts the signal to the carrier frequency, which is then applied to transformer T1. The synchronous demodulator reconstructs the input signal in the output port. A 20 kHz three-pole filter is used to reduce output noise and ripple. Finally, an output buffer outputs a low-impedance signal capable of driving a 2 kΩ load.
