AD629BRZ-R7 Typical application Circuitry

AD629BRZ-R7

The AD629BRZ-R7 is a high common-mode voltage, precision difference amplifier designed for applications where a precision, high-side current sensing or voltage difference measurement is required. It is particularly useful in situations where the common-mode voltage is beyond the range of standard operational amplifiers.

Key Features:

1. Wide Common-Mode Range: The AD629BRZ-R7 can handle common-mode voltages from -2 V to +2 V beyond the supply rails.

2. High Accuracy: Offers low offset voltage and drift, ensuring accurate measurements even in challenging conditions.

3. Flexible Power Supply: Operates with a single supply from 5 V to 36 V or dual supplies from ±2.5 V to ±18 V.

4. High Input Impedance: Ensures minimal loading of the measured signal, preserving its integrity.

5. Low Power Consumption: Suitable for battery-powered or energy-efficient applications.

Application Scenario - Current Sensing in a Motor Control Circuit:

In this scenario, the AD629BRZ-R7 is used to sense the current flowing through a motor, which is crucial for monitoring and controlling the motor's operation.

Detailed Circuit Connection:

1. Power Supply Connection: For single-supply operation, connect a +24 V supply to pin 8 (V+) and ground to pin 4 (V-).

2. Current Sense Resistor: Place a low-value resistor (Rshunt) in series with the motor, and connect the resistor's terminals to pins 2 (IN+) and 3 (IN-) of the AD629BRZ-R7.

3. Gain Setting: The AD629BRZ-R7 has a fixed gain of 0.2. No external gain setting components are required.

4. Output Voltage: The voltage difference across Rshunt, multiplied by the gain, appears at pin 6 (OUT). Connect this pin to an ADC for digital processing or to a display for direct monitoring.

5. Reference Terminal: Connect pin 5 (REF) to ground or a suitable reference voltage, depending on the desired output offset.

6. Filtering Capacitors: To minimize noise and ensure stable operation, place capacitors close to the power supply pins and the output pin.

Design Considerations:

- Precision of Rshunt: Choose a resistor with low tolerance and temperature coefficient to ensure accurate current measurement.

- Common-Mode Voltage Range: Ensure that the voltage across the motor does not exceed the common-mode voltage range of the AD629BRZ-R7.

- Thermal Management: Monitor the temperature of the AD629BRZ-R7 and the shunt resistor, as excessive heat can affect measurement accuracy.

- Signal Integrity: Implement proper PCB layout techniques to minimize noise pickup and ensure accurate measurements.

Using the AD629BRZ-R7 for current sensing in motor control circuits provides a robust and accurate solution for monitoring motor performance. Careful consideration of the circuit design and component selection will enhance the reliability and precision of the system.
