The OPA347NA/250 is a low-power operational amplifier (op amp) designed for instrumentation, buffer and linear amplifying applications. It is a single-supply, low-noise amplifier with rail-to-rail output that allows for a wide output voltage swing.

The OPA347NA/250 is designed to replace the JFET-input op amp. With its low noise, it provides a clean signal path in signal conditioning circuits, signal transmission, and within systems with high input levels. The OPA347NA/250 op amp provides a superior performance over other general-purpose op amps due to its low input offset voltage, low input bias current, high gain, high slew rate, and low distortion.

The OPA347NA/250 can act as both a single supply amplifier, with gain ranging from 0.1 Hz to 3 kHz, and a two-supply amplifier, with gain ranging from 3 kHz to 30 kHz. In either configuration, the OPA347NA/250 provides high-gain accuracy and low harmonic distortion. Within an instrumentation application, it can be used as a wide band amplifier or as a non-inverting amplifier.

The OPA347NA/250 works by inputting a signal and amplifying it before it is sent to the output. The OPA347NA/250 op amp can be used as a non-inverting amplifier, inverting amplifier, voltage follower, or a summing amplifier. The non-inverting amplifier increases the voltage of the input signal, while the inverting amplifier decreases the voltage of the input signal. The voltage follower passes the input signal with no changes, and the summing amplifier adds the two inputs together. The OPA347NA/250 has a single gain stage and offset inputs.

The OPA347NA/250 can operate with 2.7V to 12V dual supply and 4V to 12V single supply. It features an input voltage range of -2V to +2V, a bandwith of 1 MHz or 2.5 MHZ, a supply current of 500µA/channel, and a 10 nV/√Hz typical noise voltage. The OPA347NA/250 is designed to run at low current and low supply voltage within a temperature range of -40°C to +125°C.

The OPA347NA/250 is the perfect choice for instrumentation and linear amplification applications due to its low noise, low input offset voltage, low input bias current and high slew rate. With its wide output voltage swing, it can provide low harmonic distortion for a clean and accurate output. It is an excellent solution for providing precision and reliable amplification in instrumentation and buffer applications.
