Instructions for Use:

1. Power Supply:

   • The OPA2171AIDR operates with a supply voltage ranging from 1.8V to 5.5V.
   • Ensure the power supply is stable and within the specified range to avoid damage or erratic behavior.

2. Quiescent Current:

   • The quiescent current per amplifier is typically 200 渭A at 3.3V. This should be considered in low-power applications.

3. Input Offset Voltage:

   • The input offset voltage is typically 50 渭V at 3.3V. This parameter is crucial for precision applications.

4. Input Bias Current:

   • The input bias current is typically 1 pA at 3.3V, making it suitable for high-impedance sources.

5. Common-Mode Rejection Ratio (CMRR):

   • The CMRR is typically 114 dB at 1 kHz, indicating good rejection of common-mode signals.

6. Power-Supply Rejection Ratio (PSRR):

   • The PSRR is typically 114 dB at 1 kHz, ensuring minimal influence of power supply variations on the output.

7. Slew Rate:

   • The slew rate is typically 1.1 V/渭s, which limits the maximum rate of change of the output voltage.

8. Output Voltage Swing:

   • The output voltage swing is typically 0.2V to 3.1V at 3.3V supply with a 1 k惟 load. Ensure the load resistance is appropriate to achieve the desired output swing.

9. Bandwidth (Unity Gain):

   • The unity gain bandwidth is typically 1.6 MHz, which is suitable for most analog signal processing applications.

10. Large Signal Voltage Gain:

    • The large signal voltage gain is typically 100 dB, providing high amplification for small input signals.

Additional Notes:

• Stability: The OPA2171AIDR is unity-gain stable, meaning it can be used with gain settings down to 1 without oscillation.
• Temperature Range: The device is specified over the industrial temperature range of -40掳C to +125掳C.
• Package: The OPA2171AIDR is available in an 8-pin SOIC package.
