詳細說明

The UTC OPA2336 is a CMOS operational amplifier. It is operated on a 2.1V (Min.) single supply. A100kΩ load is driven by the rail-to-rail output and the accuracy of the output voltage is ensured at ± 3mV.The UTC OPA2336 is characterized by its low quiescent current (20μA/amplifier), low offset voltage (125μV max), low input bias current (1pA), and high open-loop gain (115dB).The UTC OPA2336 features completely independent circuitry for lowest crosstalk and freedom from interaction.The UTC OPA2336 is particularly designed for battery-powered applications and the common-mode range extending to the negative supply makes it ideal for single-supply applications.In addition to the applications mentioned above, the UTC OPA2336 is suitable for portable devices, high-Impedance applications, photodiode, pre-amps, precision integrators, medical instruments, and test equipment.FEATURES* Operating on a Single-Supply* Rail-to-Rail Output (Accuracy: ± 3mv)* Low Power Dissipation: IQ=20μA/Amplifier* Low Offset Voltage up to 125μV (MAX.)* Power Supply Specified from 2.3V to 5.5V* Halogen Free

主要特徵

  • Unity-gain stable design for reliable operation
  • Low input bias current of 30nA for accurate signal transmission
  • 20V/µs slew rate for fast signal response
  • ±50mA output current for driving loads directly

應用

  • High-speed amplifier for audio
  • Perfect for data acquisition
  • Great for test equipment

常見問題解答

What is OPA551FA?

The OPA551FA is a high-voltage, high-current operational amplifier designed by Texas Instruments. It is suitable for applications requiring high output current and high voltage swing, such as motor drives, power supply control, and audio amplification.

How Does OPA551FA Work?

The OPA551FA operates as a high-voltage, high-current operational amplifier capable of driving heavy loads with high precision. It can amplify signals with large voltage swings and deliver significant output current, making it suitable for demanding applications such as power amplification and motor control.

How Many Pins does OPA551FA have and What are the Functions of the Pinout Configuration?

The OPA551FA is housed in a 11-lead TO-220 or 11-lead DDPAK package. The pinout configuration includes:

  • V+: Positive power supply pin.
  • V-: Negative power supply pin.
  • NC: No connect pin (may not be internally connected).
  • OUT: Output pin.
  • V+: Positive power supply pin.
  • V-: Negative power supply pin.
  • NC: No connect pin (may not be internally connected).
  • OUT: Output pin.
  • NC: No connect pin (may not be internally connected).
  • V-: Negative power supply pin.
  • V+: Positive power supply pin.

What are the Pros and Cons of OPA551FA?

Pros:

  • High Voltage Swing: Capable of driving high voltage signals suitable for power supply control and audio amplification.
  • High Output Current: Capable of driving heavy loads such as motor drives and power amplifiers.
  • Robustness: Able to withstand high voltage and current demands in industrial applications.
  • Thermal Performance: TO-220 package allows for efficient heat dissipation.

Cons:

  • Size: The TO-220 package may be larger than other surface-mount packages, requiring more board space.
  • Heat Dissipation: Heat sink may be required in high power applications which adds to system cost and complexity.
  • Cost: May have a higher upfront cost compared to lower voltage and current op-amp alternatives.

Are There Any Equivalents/Alternatives to OPA551FA for Recommendation?

  • The OPA541 from Texas Instruments is a similar high-voltage, high-current op-amp with slight variations in specifications.
  • Alternatives to the OPA551FA include the LT1228 from Analog Devices and the PA96 from Apex Microtechnology.
