Introduction

LMH6551MMX/NOPB is a high-performance differential amplifier for instrumentation and signal conditioning applications. It delivers a wide gain-bandwidth product of 55 MHz, making it ideally suited for precision driving high-speed signals. This amplifier also provides a low input bias current of 1.2 pA while offering a robust output drive of 5.5 mA. With a wide operating supply range of 4.5 V and a low input offset of 25 µV, this amplifier is designed to provide excellent and reliable performance.

Application Field and Working Principle

The LMH6551MMX/NOPB is designed to meet the requirements of linear amplifiers, instrumentation, OP amps (operational amplifiers), buffer amps, and many other types of amplifier circuits. It offers single-ended input, single-ended output, and differential output modes of operation, making it suitable for a wide range of designs from low cost to high-end signal conditioning. This amplifier is ideal for isolating, scaling, and buffering noise-sensitive signal sources, such as remote sensors, strain gauges, and crystal oscillators, as well as application requiring long cables.

This amplifier is designed using a push-pull CMOS input and Class-AB output stage, which is coupled to a dynamic clamping stage to achieve class A biasing. This configuration provides wideband response, high linearity, low noise, and extremely low distortion. Additionally, the LMH6551MMX/NOPB also has a low-power shutdown mode, which is enabled by a logic low at the EN pin.

Features and Advantages

The LMH6551MMX/NOPB offers a wide range of features that make it an excellent choice for a variety of different applications. These features include:

  • Low Input Bias Current: The input bias current of 1.2 pA ensures that the input signal is faithfully reproduced.
  • Wide Gain-Bandwidth Product: With a wide gain-bandwidth product of 55MHz, this amplifier can accurately reproduce high-speed signals.
  • High Linearity: The amplifier offers excellent linearity, with a low Total Harmonic Distortion (THD) of 0.001%.
  • Robust Output Drive: The amplifier can provide up to 5.5 mA of output drive which is suitable for driving long cables.
  • Low-Power Shutdown Mode: This amplifier can be put into a low-power shutdown mode when a logic low is applied at the EN pin.
  • Wide Operating Supply Range: The amplifier is capable of operating at supply voltages of 4.5 V.
  • Low Input Offset Voltage: The amplifier has a low input offset voltage of 25 µV, ensuring accurate operation.

These features combine to make the LMH6551MMX/NOPB an excellent choice for high performance and reliable signal conditioning applications.

Conclusion

The LMH6551MMX/NOPB is a high-performance differential amplifier designed for instrumentation and signal conditioning applications. It offers a wide range of features including low input bias current, wide gain-bandwidth product, high linearity, robust output drive, and low-power shutdown mode. These features make it an ideal choice for precision driving high-speed signals and long cable runs.
