LT6604IUFF-5#PBF is an instrumentation operational amplifier. It is designed to provide precision performance with optimized transient response and minimum settling time while operating from a single +5V power supply. Its performance is further enhanced by using a proprietary high level-shifting output stage and a wide supply range of +3V to +5V. The rail-to-rail input stage helps achieving wide dynamic range of applications like buffering, A/D and D/A converters.

The LT6604IUFF-5#PBF has a wide range of application possibilities. This device is suitable for applications like buffering, low frequency transimpedance amplifiers, transducer linearization and closed loop gain control. Its higher output current and rail-to-rail ability makes it ideal in current-to-voltage and voltage-to-current conversion as it can drive a maximum load of ±250mA with slew rates of up to ±600V/µs. It also has a very low input bias current of 2nA that makes it suitable for low impedance input sources. It has an excellent slew rate and the low noise makes it suitable for noise-sensitive applications. It is also widely used in instrumentation and power converters.

The working principle of the LT6604IUFF-5#PBF can be explained by considering an ideal op-amp circuit, wherein all the electrical parameters like gain, output voltage, input resistance, output resistance, etc. are assumed to be ideal. The amplifier is connected to a negative feedback circuit, where the output voltage is fed-back to the input. The input is a voltage source and the output is a current source. This circuit amplifies the input differential voltage by a set gain. Through the negative feedback path, by varying the gain and the feedback resistance, different control outputs can be generated.

The LT6604IUFF-5#PBF uses a proprietary high level-shifting output stage, allowing the output voltage swing to reach rail-to-rail voltage levels. This helps achieve wide dynamic range of applications, especially for A/D and D/A converters. The output stage also enables the device to drive a wide variety of loads from very low to very high, to achieve optimized transient response and minimum settling time. The input stage uses the same high level-shifting technique and the low input bias current of 2nA makes it suitable for very low impedance input sources. The device also features a wide supply range of +3V to +5V.

The LT6604IUFF-5#PBF has many applications in buffering, A/D and D/A converters. It can also be used as current-to-voltage and voltage-to-current converters, transducer linearization, low frequency transimpedance amplifiers and closed loop gain control. This device has an excellent slew rate and low noise, making it ideal for noise-sensitive applications.
