AD210AN Overview

The AD210AN is the most recent member of a new class of high-quality, affordable isolation amplifiers. This surface-mounted, automated assembly procedure is used to create this three-part, broad bandwidth isolation amplifier. The AD210AN creates a very compact and affordable isolator whose performance and abundance of user features greatly exceed those provided by more expensive devices by combining design experience with cutting-edge manufacturing technology.

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.

The fundamental block diagram for the AD210AN is shown below in Figure 1. The power port is connected to a +15 V supply, and the input and output ports receive isolated 15 V power at a carrier frequency of 50 kHz. The uncommitted input amplifier can give the AD210AN gain or a buffer. The signal is changed to the carrier frequency via the full-wave modulator and then applied to transformer T1. The output port of the synchronous demodulator reconstructs the input signal. The output noise and ripple are decreased using a 20 kHz three-pole filter. An output buffer then produces a low-impedance signal that can drive a 2 k load.

AD210AN Usages

It is quite easy to use the AD210AN in a multitude of applications. In both single-channel and multichannel systems, the AD210AN, which is powered by a single +15 V power source, excels as an input or output isolator.

Figure 2 shows the fundamental unity gain configuration for signals up to 10 V. Additional types of input amplifiers are shown in the figures below. Figure 3 demonstrates how to maintain a very high input impedance for lower signal levels while achieving gain.

The circuits in Figures 2 and 3 can maintain their high input impedance in an inverting application. Signal inversion is possible with the AD210AN's three ports by switching the input and output leads.

Figure 4 demonstrates how to accept input currents, total currents, or voltages. Signals greater than 10 V can also be used with this circuit arrangement. For instance, RF = 20 k and RS1 = 200 k can withstand a 100 V input span.
