• High common mode rejection ratio: 87dB

Working Principle:

The TS27M2IDT is a two-output, low-power op-amp integrated circuit. It amplifies the input signal by combining the differential input signals from two separate output lead sets. The differential signals are then amplified and converted into a single-ended output signal. The amplifier uses a symmetrical operaing point, which ensures that its gain remains consistent across its entire operating range. It also uses a low-noise loop feedback mechanism, which minimizes any noise introduced by the amplifier.

The input is connected to the base of the first Op Amp and the output is connected to the emitter of the second Op Amp. The collector is connected to the feedback components, which include resistors, capacitors and inductors. The feedback components adjust the gain of the amplifier and maintain the gain accuracy across the amplifier\'s working range. The capacitors filter the input and output signals, while the inductors provide higher frequency immunity from noise. The combination of the feedback components and the Op Amps form a loop, which amplifies the signal. The output is fed back to the input, so the amplifier can maintain its gain accuracy regardless of the input and output levels.

Advantages:

• High gain linearity: 14 dB
• High common-mode and differential-mode rejection: 87dB
• Very low supply current: 5.1mA
• Wide gain range: 0.5V to 27V
