GENERAL DESCRIPTION The AD8210 is a single-supply, difference amplifier ideal for amplifying small differential voltages in the presence of large common-mode voltages. The operating input common-mode voltage range extends from −2 V to +65 V. The typical supply voltage is 5 V. The AD8210 is offered in a SOIC package. The operating temperature range is −40°C to +125°C. Excellent ac and dc performance over temperature keep errors in the measurement loop to a minimum. Offset drift and gain drift are guaranteed to a maximum of 8 μV/°C and 20 ppm/°C, respectively. Rev. D The output offset can be adjusted from 0.05 V to 4.9 V with a 5 V supply by using the VREF1 pin and the VREF2 pin. With the VREF1 pin attached to the V+ pin and the VREF2 pin attached to the GND pin, the output is set at half scale. Attaching both VREF1 and VREF2 to GND causes the output to be unipolar, starting near ground. Attaching both VREF1 and VREF2 to V+ causes the output to be unipolar, starting near V+. Other offsets can be obtained by applying an external voltage to VREF1 and VREF2. Document Feedback Information furnished by Analog Devices is believed to be accurate and reliable.

D | Page 9 of 16 AD8210 Data Sheet THEORY OF OPERATION The differential currents through Q1 and Q2 are converted into a differential voltage by R3 and R4. A2 is configured as an instrumentation amplifier. The differential voltage is converted into a single-ended output voltage by A2. The gain is internally set with precision-trimmed, thin film resistors to 20 V/V. In typical applications, the AD8210 amplifies a small differential input voltage generated by the load current flowing through a shunt resistor. The AD8210 rejects high common-mode voltages (up to 65 V) and provides a ground referenced buffered output that interfaces with an analog-to-digital converter (ADC). Figure 26 shows a simplified schematic of the AD8210. The output reference voltage is easily adjusted by the VREF1 pin and the VREF2 pin. In a typical configuration, VREF1 is connected to VCC while VREF2 is connected to GND. In this case, the output is centered at VCC/2 when the input signal is 0 V. The AD8210 is comprised of two main blocks, a differential amplifier and an instrumentation amplifier. A load current flowing through the external shunt resistor produces a voltage at the input terminals of the AD8210. The input terminals are connected to the differential amplifier (A1) by R1 and R2. A1 nulls the voltage appearing across its own input terminals by adjusting the current through R1 and R2 with Q1 and Q2. When the input signal to the AD8210 is 0 V, the currents in R1 and R2 are equal. When the differential signal is nonzero, the current increases through one of the resistors and decreases in the other. The current difference is proportional to the size and polarity of the input signal.

D | Page 10 of 16 Data Sheet AD8210 MODES OF OPERATION The AD8210 can be adjusted for unidirectional or bidirectional operation. UNIDIRECTIONAL OPERATION Unidirectional operation allows the AD8210 to measure currents through a resistive shunt in one direction. The basic modes for unidirectional operation are ground referenced output mode and V+ referenced output mode. V+ Referenced Output This mode is set when both reference pins are tied to the positive supply. It is typically used when the diagnostic scheme requires detection of the amplifier and wiring before power is applied to the load (see Figure 28 and Table 5). RS +IN –IN In unidirectional operation, the output can be set at the negative rail (near ground) or at the positive rail (near V+) when the differential input is 0 V. The output moves to the opposite rail when a correct polarity differential input voltage is applied. In this case, full scale is approximately 250 mV. The required polarity of the differential input depends on the output voltage setting. If the output is set at ground, the polarity needs to be positive to move the output up (see Table 5). If the output is set at the positive rail, the input polarity needs to be negative to move the output down (see Table 6). VS AD8210 0.1µF VREF 1 OUTPUT G = +20 Ground Referenced Output VREF 2 When using the AD8210 in this mode, both reference inputs are tied to ground, which causes the output to sit at the negative rail when the differential input voltage is zero (see Figure 27 and Table 4). 05147-006 GND Figure 28.

The output offset can be set anywhere within the output range. Typically, it is set at half scale for equal measurement range in both directions. In some cases, however, it is set at a voltage other than half scale when the bidirectional current is nonsymmetrical. Table 6.

D | Page 11 of 16 AD8210 Data Sheet External Referenced Output RS Tying both VREF pins together to an external reference produces an output offset at the reference voltage when there is no differential input (see Figure 29). When the input is negative relative to the −IN pin, the output moves down from the reference voltage. When the input is positive relative to the −IN pin, the output increases. +IN –IN VS AD8210 RS +IN 0.1µF VREF 1 VREF –IN 0V ≤ VREF ≤ VS VS G = +20 0.1µF OUTPUT AD8210 VREF 2 VREF 0V ≤ VREF ≤ VS GND 05147-008 VREF 1 OUTPUT Figure 30. Split External Reference G = +20 Splitting the Supply GND 05147-007 VREF 2 Figure 29. External Reference Output Splitting an External Reference In this case, an external reference is divided by two with an accuracy of approximately 0.2% by connecting one VREF pin to ground and the other VREF pin to the reference voltage (see Figure 30). By tying one reference pin to V+ and the other to the GND pin, the output is set at midsupply when there is no differential input (see Figure 31). This mode is beneficial because no external reference is required to offset the output for bidirectional current measurement. This creates a midscale offset that is ratiometric to the supply, meaning that if the supply increases or decreases, the output still remains at half scale. For example, if the supply is 5.0 V, the output is at half scale or 2.5 V. If the supply increases by 10% (to 5.5 V), the output also increases by 10% (2.75 V). Note that Pin VREF1 and Pin VREF2 are tied to internal precision resistors that connect to an internal offset node. There is no operational difference between the pins. RS +IN –IN VS For proper operation, the AD8210 output offset should not be set with a resistor voltage divider. Any additional external resistance could create a gain error. A low impedance voltage source should be used to set the output offset of the AD8210. AD8210 0.1µF VREF 1 G = +20 OUTPUT VREF 2 05147-009 GND Figure 31. Split Supply Rev. D | Page 12 of 16 Data Sheet AD8210 INPUT FILTERING In typical applications, such as motor and solenoid current sensing, filtering at the input of the AD8210 can be beneficial in reducing differential noise, as well as transients and current ripples flowing through the input shunt resistor. An input lowpass filter can be implemented as shown in Figure 32. Adding outside components, such as RFILTER and CFILTER, introduces additional errors to the system. To minimize these errors as much as possible, it is recommended that RFILTER be 10 Ω or lower. By adding the RFILTER in series with the 2 kΩ internal input resistors of the AD8210, a gain error is introduced. This can be calculated by The 3 dB frequency for this filter can be calculated by 1 2 kΩ Gain Error (%) = 100 − 100 × 2 kΩ − RFILTER (1) 2π × 2 × RFILTER × C FILTER RSHUNT < RFILTER RFILTER ≤ 10Ω RFILTER ≤ 10Ω CFILTER +IN –IN VS 0.1µF AD8210 VREF VREF 1 0V ≤ VREF ≤ VS OUTPUT G = +20 VREF 2 GND 05147-013 f _ 3 dB = Figure 32. Input Low-Pass Filtering Rev. D | Page 13 of 16 (2) AD8210 Data Sheet APPLICATIONS INFORMATION The AD8210 is ideal for high-side or low-side current sensing. Its accuracy and performance benefits applications, such as 3-phase and H-bridge motor control, solenoid control, and power supply current monitoring. For solenoid control, two typical circuit configurations are used: high-side current sense with a low-side switch, and high-side current sense with a high-side switch. 5V 0.1µF SWITCH BATTERY 5V VREF 1 –IN GND +VS VREF 2 CLAMP DIODE NC 05147-011 NC = NO CONNECT Figure 34. High-Side Switch Using a high-side switch connects the battery voltage to the load when the switch is closed. This causes the common-mode voltage to increase to the battery voltage. In this case, when the switch is opened, the voltage reversal across the inductive load causes the common-mode voltage to be held one diode drop below ground by the clamp diode. Another typical application for the AD8210 is as part of the control loop in H-bridge motor control. In this case, the AD8210 is placed in the middle of the H-bridge (see Figure 35) so that it can accurately measure current in both directions by using the shunt available at the motor. This configuration is beneficial for measuring the recirculation current to further enhance the control loop diagnostics.

Low-Side Switch In this circuit configuration, when the switch is closed, the common-mode voltage moves down to the negative rail. When the switch is opened, the voltage reversal across the inductive load causes the common-mode voltage to be held one diode drop above the battery by the clamp diode. MOTOR +IN VREF 1 –IN GND +VS OUT AD8210 SHUNT VREF 2 NC 5V 2.5V HIGH-SIDE CURRENT SENSE WITH A HIGH-SIDE SWITCH NC = NO CONNECT This configuration minimizes the possibility of unexpected solenoid activation and excessive corrosion (see Figure 34). In this case, both the switch and the shunt are on the high side. When the switch is off, the battery is removed from the load, which prevents damage from potential short circuits to ground, while still allowing the recirculation current to be measured and diagnostics to be preformed. Removing the power supply from the load for the majority of the time minimizes the corrosive effects that could be caused by the differential voltage between the load and ground. Figure 35. Motor Control Application The AD8210 measures current in both directions as the H-bridge switches and the motor changes direction. The output of the AD8210 is configured in an external reference bidirectional mode (see the Modes of Operation section). Rev. D | Page 14 of 16 05147-012 BATTERY –IN +VS INDUCTIVE LOAD In this case, the PWM control switch is ground referenced. An inductive load (solenoid) is tied to a power supply. A resistive shunt is placed between the switch and the load (see Figure 33). An advantage of placing the shunt on the high side is that the entire current, including the recirculation current, can be measured because the shunt remains in the loop when the switch is off. In addition, diagnostics can be enhanced because short circuits to ground can be detected with the shunt on the high side.
