The LT1126ACN8 is an instrumentation amplifier that features a uniquely low input voltage noise, providing high performance in systems that must detect minute signals in the presence of high common mode noise. With excellent DC precision and reliable stability, very large gain can be realized even with very small signals. The small differential voltage noise, output offset voltage, and a high output current drive make the LT1126ACN8 ideal for a wide range of applications, including electronic transducers, precision zero balance, and low-level control loops.

The LT1126ACN8 provides adjustable gain from 10 to 200,000 with a gain set pin that allows easy adjustment of the gain without sacrificing noise performance. Additionally, the LT1126ACN8 can be configured for unipolar or bipolar operation, as well as single or differential input. The adjustable output stage of the LT1126ACN8 also provides flexibility in designing both AC and DC applications.

The LT1126ACN8 works using a fully differential amplifier with a specially designed gain set resistor network. The differential input stage consists of two low noise NPN transistors, a gain setting resistor, and a trim resistor. This arrangement allows a wide range of gains to be achieved while still providing high precision. The gain setting resistor is used to adjust the gain of the circuit, while the trim resistor is used to fine-tune the gain. The differential input stage then drives an output stage which can be configured as a single ended or push-pull amplifier, depending on the application. In either configuration, the output swing features low distortion and low settling time.

The LT1126ACN8 is also designed to operate over a wide input and output voltage range, allowing for both AC and DC signals to be amplified. With a stable power supply, the LT1126ACN8 can provide a very accurate amplification of signals. Additionally, the LT1126ACN8 can be powered from a single or dual supply, providing further flexibility for the system design.

The LT1126ACN8 is ideal for instrumentation and monitoring applications, as well as for various types of control systems. Its low noise, high gain, and adjustable gain make it suitable for use in medical and scientific instrumentation, motion control, light control, bio-sensing, and industrial process monitoring. It is also ideal for use in precision measurement systems, such as force measurement and temperature control. The LT1126ACN8 is also suitable for analog-to-digital conversion, voltage regulation, and motor control applications.

The LT1126ACN8 provides excellent performance, stability, and flexibility, making it well suited for a wide range of applications. Its adjustable gain allows for a wide range of gains to be realized, while its stability and low noise provide accuracy and reliability. The LT1126ACN8 also offers a wide input and output voltage range, allowing for both AC and DC signals to be accurately amplified. With its versatility, the LT1126ACN8 is well-suited for instrumentation and monitoring, as well as for various control systems.
