The OPA137UAG4 is a low-noise, rail-to-rail input and output, single-supply operational amplifier (op amp) designed for very low-noise applications in audio, instrumentation and medical markets. This high-performance amplifying device is optimized for very low noise with a 0.8nV/√Hz at 1kHz and 4.5nV/√Hz at 10kHz noise spectral density. It also features rail-to-rail input/output with wide bandwidth of 2.3MHz (-3dB) and excellent output drive capability of ±5mA with a single 5V supply. The OPA137UAG4 is used to linearize, buffer, filter and condition instrumentation, audio, medical and distributed amplifier applications.

The OPA137UAG4 works by utilizing transistors to amplify electrical signals. A typical op amp consists of two input terminals (the inverting and non-inverting inputs) that are connected internally to a differential amplifier. This amplifier amplifies the difference between the two inputs, such that an input voltage difference of 1mV will result in an output voltage of volts. The output voltage is then coupled to external components to produce the desired amplification, filtering and other signal conditioning effects.

The OPA137UAG4 has been designed to provide high accuracy and low-noise performance. Its wide input voltage range (1.8 to 6V) and rail-to-rail input/output enables it to handle a wide range of application requirements. Its output drive capability of ±5mA enables it to deliver high performance in low power applications. The OPA137UAG4 also has a wide bandwidth of 2.3MHz (-3dB) so that it can be used for a wide range of signal conditioning and audio applications.
