AD640TE/883B Linear-Amplifiers-Instrumentation, OP Amps, Buffer Amps

The AD640TE/883B is a high-performance instrumentation amplifier that provides excellent accuracy and low noise performance.

The design features of the AD640TE and AD640TE/883B provide a significant performance improvement for precision applications and for use in high-performance instrumentation systems.

The AD640TE/883B is a general purpose instrumentation amplifier that provides exceptional accuracy, low noise, and low power consumption. It is designed to be used in applications such as data conversion and data acquisition systems, sensor amplifiers, bridge-based sensor amplifiers, thermocouples, strain gauges, load cells, and other precision applications. The AD640TE/883B is also suitable for other general-purpose instrumentation applications, such as signal conditioning, direct access data acquisition, data integration and additional applications which require low-noise and high accuracy.

The AD640TE/883B features a low offset voltage amplifier, a voltage follower amplifier and a unity gain buffer amplifier. The offset voltage amplifier is a single-ended input, high input impedance, adjustable gain amplifier with a low offset voltage and a high common-mode rejection ratio. The voltage follower amplifier is a single-ended input, high impedance amplifier with adjustable gain. The buffer amplifier is an adjustable gain amplifier with unity gain (1:1 ratio).

The AD640TE/883B provides an exceptionally low input offset voltage (typically 10µV) and low input bias current (typically 1 pA), allowing precision measurements over a wide temperature range. Additionally, the significantly low input voltage noise of usually 0.5nV/sqrtHz adds to the accuracy in its applications. It also has a wide dc gain range of 1000 to 10 million, enabling it to accommodate a very large number of applications.

The AD640TE/883B also features a sigma-delta modulator which allows it to operate efficiently and with low power consumption. A buffer amplifier is also integrated in the design, to provide isolation between the input and output signals. This design also provides low distortion, low temperature coefficient and low slew rate.

The output of the AD640TE/883B is very linear, due to the low offset and low noise features. The amplifier collects signals from multiple sensors without introducing any errors, thus providing an accurate output. In addition, the high common-mode rejection ratio enables it to reject any environmental noise, making it ideal for use in noise-sensitive applications.

The AD640TE/883B is also designed with a wide operating temperature range of -25 C to +85 C, making it suitable for use in extreme temperatures. The amplifier also has an excellent power supply rejection ratio of 105 dB, making it very stable in noisy environments.

Overall the AD640TE/883B is an excellent instrumentation amplifier for any precision application. Its high accuracy and low noise performance make it an ideal choice for high-performance data acquisition systems, signal conditioning, data conversion and other instrumentation applications.
