INA188IDR Typical application Circuitry

INA188IDR

The INA188IDR is a zero-drift, instrumentation amplifier (In-Amp) manufactured by Texas Instruments. It is designed with the precision and power-saving features suitable for a broad range of applications.

Key Features of INA188IDR:

1. Low Offset and Drift: The INA188IDR is offset voltage is as low as 5 μV (maximum) with a drift of only 0.005 μV/°C.

2. Wide Supply Range: This chip can be powered by a supply range of 2.7V to 5.5V, which is suitable for battery-powered applications.

3. High Accuracy: The chip exhibits a high common-mode rejection ratio (CMRR) of 124 dB.

4. Flexibility: It has a wide input range that extends 150 mV beyond the rails, and the gain can be set from 1 to 1000.

Application Scenarios for INA188IDR:

The INA188IDR is typically used in precision applications, such as temperature measurement with thermocouples, RTDs, and thermistors, bridge amplifiers for pressure and load cells, and current shunt measurements.

Current Measurement Example in a Circuit:

The INA188IDR can function as a differential amplifier to gauge the voltage drop across a shunt resistor for current measurement in a power supply rail:

- Pin 1 (REF): Connect this pin to the midpoint of a voltage divider that is tied to the power supply rails. This sets the reference voltage for the output signal.

- Pin 2 (IN-): Connect this pin to the shunt resistor's node connected to the load side.

- Pin 3 (IN+): Connect this pin to the shunt resistor's node connected to the power supply.

- Pin 4 (GND): Join this pin to the power supply's ground.

- Pin 5 (V-): Connect this pin to the power supply's negative terminal. For single-supply operation, this pin connects to the ground.

- Pin 6 (V+): Connect this pin to the positive terminal of your power supply.

- Pin 7 (OUT): The output voltage proportional to the measured current is obtained from this pin.

- Pins 8 and 9 (RG): An external resistor connected between these two pins sets the amplifier's gain.

Considerations when using INA188IDR:

1. Choice of Shunt Resistor: The value of the shunt resistor in current measurements needs to be chosen such that it creates only a minimal voltage drop at the maximum current level.

2. Common-Mode Voltage: The INA188IDR allows for a wide range of common-mode voltages, but one must ensure that the chosen common-mode voltage does not exceed the supply voltage.

3. Power Supply Decoupling: To ensure consistent operation, decoupling capacitors should be positioned close to the power supply pins.

4. Proper Gain Setting: The gain of the INA188IDR is determined by the external resistor connected between pins 8 and 9. The gain must be set accurately to ensure the output signal's appropriate range.

The INA188IDR is a high-accuracy, low-drift instrumentation amplifier suitable for many precision applications, including current sensing, temperature measurements, and industrial process control.
