The OPA2340EA/250 is a high-performance, low-power-dissipation, unity-gain-stable, low-voltage, CMOS operational amplifier that is specifically designed for portable and instrumentation applications. It is ideal for power amplifiers, sample-and-hold amplifiers, integrators, fast-settling sample-and-hold trackers, filters, comparators, high-accuracy instrumentation amplifiers, high-speed integrators and other applications in the linear-amplifiers-instrumentation, OP-amps-buffer-amps arena.

The OPA2340EA/250 is housed in a compact SOIC16 package, and is designed to operate over a temperature range of -40°C to +85°C. It is specified to perform at low-supply voltages from 2.7V to 5.5V, with a maximum supply current of 1.5mA. It features a fast settling time of 4.5µs at 4V/μs slew rate, an 800kHz gain-bandwidth product, a Slew Rate of 4.2V/μs, and an input noise voltage of 5nV/√Hz. This combination of features is an ideal solution for high-accuracy, low-power instrumentation applications.

The OPA2340EA/250 features a unique internally compensated, three-stage architecture that eliminates the need for external capacitors. This eliminates the need for external input current-noise cancellation and enables a low-distortion output from the amplifier. The resulting amplifier is characterized by excellent crossover-distortion performance, low output noise and excellent linearity over a wide range of input signals. The OPA2340EA/250 is designed to ensure accurate representation of signals in low-voltage, portable, and instrumentation applications, and is a great choice for creating high-accuracy and linear audio and DC precision solutions.

The OPA2340EA/250 is a unity gain stable amplifier, and has multiple modes of operation. The unity gain bandwidth of 800kHz allows for ample bandwidth for high-speed applications, while maintaining the desired output waveforms. The high slew rate enables the amplifier to deliver a high gain response quickly, while remaining stable under a wide range of input levels. Additionally, the OPA2340EA/250 features a low supply-current of 1.5 mA, which is essential for portable design applications.

The working principle of the OPA2340EA/250 is relatively simple compared to other operational amplifier designs. The internal architecture of the amplifier is composed of three stages: input, gain, and output stage. The input stage is composed of an amplifier, which amplifies the input signal in stages. This signal is then sent to the gain stage, which provides the overall gain to the signal. Finally, the output stage amplifies the signal again, before it is output from the amplifier.

The key advantages of the OPA2340EA/250 is its combination of high gain-bandwidth product, low supply-current and wide temperature range. These features enable it to provide superior performance and high accuracy in low-voltage, portable and instrumentation applications. Additionally, the amplifier is unity gain stable and has a low input voltage noise voltage that helps minimize signal distortion in high-accuracy systems. Overall, the OPA2340EA/250 is an ideal solution for the linear-amplifiers-instrumentation, OP-amps-buffer-amps arena, providing an ideal combination of high-speed, low power consumption and accurate signal representation.
