The INA129UA/2K5E4 is a high performance differential input precision instrumentation amplifier that has a wide range of uses in many different application fields. It is well suited for precision signal conditioning of current, voltage and other signals that require low-noise and wide bandwidth. This instrumentation amplifier is designed to be used in high precision applications such as medical, industrial and audio applications. It is also suitable for use in automotive, communications, instrumentation and test/measurement applications.

The INA129UA/2K5E4 is built using a differential input stage and a highly accurate differential-gain amplifier buffer stage. The differential inputs are designed to accept a wide range of input signals with low offset voltages. This instrumentation amplifier is capable of driving low impedance loads, including single-ended loads, without significant offset errors. It complies with the EMC and safety requirements of the generic industrial standard EN55020 for electromagnetic compatibility.

The gain of the amplifier is programmable from 0 dB to maximum gain of 2k5. The gain select pins can be used to select fixed gains of 0 dB, 5 dB, 10 dB, 15 dB, 20 dB, 25 dB, and 30 dB. The gain accuracy is guaranteed over the entire signal range. The amplifier can provide an output voltage signal of up to 2.6 V without any external components. The amplifier is also capable of providing an output signal of up to 10V with the help of external components.

The INA129UA/2K5E4 utilizes a wide bandwidth bandgap reference voltage source that provides excellent linearity, accuracy and AC common-mode rejection. The amplifier has a low supply current (800uA) and a low input current offset (less than 2nA). Additionally, it has a low noise level (5nV/√Hz) with a gain bandwidth of 500kHz and high slew rate at over 1.4V/μs. The amplifier also includes additional features such as common-mode range expansion, rail-to-rail input and output swing capability, and low power operation.

The INA129UA/2K5E4 is a great choice for precision signal conditioning and instrumentation applications. Its wide range of features and capabilities make it an ideal choice for high-precision applications. It can easily be used as part of design systems such as data acquisition systems, digital-to-analog converters and more. Its low input current offset and low noise level make it well suited for medical, industrial and audio applications.
