BD7542F-E2 application field and working principle

The BD7542F-E2 is a high performance, low power dual-channel power amplifier designed for signal acquisition applications. It’s well-suited for portable instruments where precision, long-term stability and low noise are required.

As an instrumentation amplifier, the BD7542F-E2 is used to amplify low-level signals such as electrocardiograms, temperature and pressure sensor readings, or bridge signals. It also offers high-input impedance and low-noise performance compared to other amplifier types.

The BD7542F-E2 provides two separate, independent amplifier channels or two amplifiers in one package. The two amplifiers can work together to provide a balanced output for increased accuracy, or can be configured for different gains. Each amplifier has a wide power supply range and can be configured for single-ended or balanced output.

The BD7542F-E2 uses an active input stage to ensure low noise operation and high gain accuracy. It also features an adjustable output stage to reduce output impedance. The BD7542F-E2 is designed for low power operation, making it ideal for battery-powered instruments.

Working Principle:

The BD7542F-E2 is composed of two operational amplifier stages, the gain of which is controlled by two feedback resistors. The gain can be changed simply by changing the resistors. The two outputs can then be combined to create a differential signal. The voltage gain is set by the feedback resistors and the inverting and non-inverting inputs of the amplifier.

The output stage of the BD7542F-E2 reduces output impedance to reduce noise and ensure a stable gain. The output stage is adjustable, allowing it to be configured for single-ended or balanced output. The output stage is also designed for low power operation, allowing it to be used in battery-powered applications. Furthermore, the BD7542F-E2 is designed to reduce noise and distortion, ensuring accurate and reliable signals.

Conclusion:

The BD7542F-E2 is a high performance, low power dual-channel instrumentation amplifier designed for signal acquisition applications. It offers high gain accuracy, low noise operation and adjustable output stage to reduce output impedance. The BD7542F-E2 is well-suited for portable instruments such as electrocardiograms, temperature and pressure sensors, and bridge signals. The BD7542F-E2 is an ideal choice for applications that require precision, long-term stability and low power operation.
