The BD12734FV-GE2 is an integrated linear amplifier designed for instruments and other industrial applications. The key features of the BD12734FV-GE2 include low noise, high gain, wide bandwidth, low distortion, low offset and low power consumption.

The BD12734FV-GE2 is typically used in instrumentation systems, such as pressure transducers, sensors, weighing scales, load cells and motor position controllers. It has a high amplification coefficient of up to 1000V/V, a bandwidth of up to 350 kHz, a low noise level of 10 nV/√Hz and an input offset voltage of up to 6 mV. The total harmonic distortion is also low, as it is below 0.01%.

The working principle of the BD12734FV-GE2 is based on the classical inverting amplifier configuration, with a differential input stage, a gain-setting stage, an output stage and a biasing stage. The differential input stage consists of two differential transistors, which match the input signal to the gain-setting stage. In the gain-setting stage, an OP amp is used to set the gain of the amplifier. The output stage consists of a pair of complimentary transistors, which are used to convert the RF signal from the gain-setting stage into complementary outputs. Finally, the biasing stage is responsible for setting the bias voltage for the OP amp, so that its input signal is centered at the mid-point (e.g. 0.5V).

The BD12734FV-GE2 is a versatile linear amplifier suitable for many applications, such as in audio, medical, automotive and instrumentation systems. It provides high linearity, wide bandwidth and low noise, making it ideal for a variety of measurement and control applications. It is also easy to control and can be used with a wide range of signal sources.
