LT3469ETS8#TRPBF

Introduction

LT3469ETS8#TRPBF is a Linear-Amplifiers-Special Purpose. It is a precision low power amplifier designed for a wide range of applications.

Application Field

The LT3469ETS8#TRPBF is specially designed for remote control systems, wireless data links, audio and video distributed systems, portable instrumentation, and automotive systems. The device provides user-programmable gain up to 50dB in 1dB steps and supply current of only 27mA when both supplies are at 3V. Perfect match to the input biasing allows input common mode voltage levels as low as 0.5V, while output common mode voltages as low as 0.9V. Therefore, this device is excellent for low voltage applications with no external biasing components required.

Working Principle

The LT3469ETS8#TRPBF utilizes a differential input stage for supply rejection and low noise. The gain of the amplifier is adjustable with a single external resistor. The output of the device has an output isolation MOSFET isolator to protect the sensing circuitry from high output voltages and high output current. The device is designed to operate from a 3V to 5V single power supply, and interfaces with a wide range of signal levels.

The LT3469ETS8#TRPBF is designed with low input offset voltage and low thermal drift to provide high accuracy operation. The high common mode rejection of the differential input stage reduces errors due to system voltage and common mode noise. In addition, the use of a low power regulator and internal filtering provides excellent noise immunity and improved DC accuracy.

The device supports fast settling times in the presence of large capacitive loads which makes it ideal for applications where high frequency signal settling characteristics are important. In addition, the device is designed to exhibit low power dissipation, so the system can operate over extended periods of time without significantly increasing the temperature of the system.

Finally, the LT3469ETS8#TRPBF has differential outputs that are compatible with wide input range amplifier designs. This allows the designer to use higher resolution converters, as well as providing better voltage and current noise immunity.

Conclusion

In conclusion, the LT3469ETS8#TRPBF is an industry leading device for Linear-Amplifiers-Special Purpose purpose, providing excellent noise immunity and wide range signal compatibility. The device is ideally suited for applications such as remote control systems, wireless data links, audio and video distributed systems, portable instrumentation, and automotive systems.
