The OPA3684IDBQT is a high-speed low power, precision operational amplifier from Texas Instruments. It is part of the OPAx684 family of ultra-low-noise, high-precision operational amplifiers which are very suitable for multiple applications, including medical device instrumentation, precision measurement, high-performance consumer applications and general purpose operational amplifier usage. The OPA3684IDBQT boasts high output current and low distortion to provide superior performance when compared to competing devices. It utilizes an innovative transient-free output stage that enables high speed operation, excellent ac and transient performance, as well as a wide common-mode voltage range. With its low power consumption and superior thermal performance, the OPA3684IDBQT is an ideal choice for energy-sensitive applications.

OPA3684IDBQT is mainly used in audio, instrumentation and measurement applications such as mixers, filters, integrators and high-speed waveform acquisition. It can also be used in closed-loop feedback circuits, where its low noise and distortion performance provide an extremely accurate response for applications that require high level of accuracy. Its wide power supply range (2.7V to 7.5V) also makes it an ideal choice for applications that require low power consumption.

The OPA3684IDBQT has a basic structure that features a dual input stage and a custom output stage. The dual input stage consists of four cascode-connected common-emitter (CE) differential pairs, connected to the first four of eight selectable gain elements. Each gain element is composed of a pair of transistors connected in parallel, where one is of higher current gain (H) and the other is of lower current gain (L). The custom output stage consists of a differential version of the cascode pair formed by four balanced outputs. The output stage includes both an output impedance buffering stage and an output amplifier stage. A complimentary output stage is also included for precise control of the output voltage swings.

The OPA3684IDBQT is designed to provide a wide bandwidth while maintaining a high level of accuracy and stability. The bandwidth is achieved through the combination of the distortion-free input stage, high-speed output stage, and low output impedance. The precision and accuracy of the OPA3684IDBQT is achieved through its precision process control, which allows the output voltage swing to be set accurately and with no offset. The wide bandwidth, high-accuracy and low power consumption make the OPA3684IDBQT an ideal choice for applications such as precision amplifier designs, audio applications, test and measurement applications, and medical instrumentation.
