AD8556ACPZ-REEL7 Introduction

AD8556ACPZ-REEL7 is a high performance, wideband and low power programmable gain amplifier (PGA). It is a wideband current feedback amplifier with bandwidth from 0.025 Hz to 26 MHz and low power consumption. It also has an adjustable gain which can be up to 40 dB and a low start-up power of 0.6 mA. It is widely used in automotive, professional audio, telecom, medical and RF applications.

AD8556ACPZ-REEL7 Application Field

AD8556ACPZ-REEL7 is mainly used in linear amplification applications. It is suitable for use in amplifying small signals that require high accuracy measurement such as temperature and pressure. It is also used in instrumentation amplifiers, operational amplifiers, buffer amplifiers and other circuit applications.

AD8556ACPZ-REEL7 Working Principle

The AD8556ACPZ-REEL7 uses current feedback to amplify the input signal. By adjusting the gain of the amplifier, the noise that accompanies the signal can be reduced and the signal-to-noise ratio can be improved. It also has a low power consumption and a built-in automatic power-down function. It is designed to reduce electromagnetic interference (EMI) with a low noise floor of –80 dBFS. The AD8556ACPZ-REEL7 also has a wide supply voltage range of 3.3V to 12V. The amplifier has an integrated gate driver and two output pins for complementary outputs. The output can be configured as either a single-ended output or complementary balanced output, depending on the application. Additionally, the AD8556ACPZ-REEL7 offers voltage feedforward for improved stability and a protection circuit for overvoltage and overcurrent. The amplifier enables small-sized designs in many applications.

Conclusion

The AD8556ACPZ-REEL7 is a high performance, wideband and low power programmable gain amplifier (PGA). It is designed for linear amplification applications, instrumentation amplifiers, operational amplifiers, buffer amplifiers and other circuit applications. It has adjustable gain up to 40 dB and low power consumption. It also has a wide supply voltage range of 3.3V to 12V and can be configured as a single-ended or balanced output. Additionally, it has built-in automatic power-down, voltage feedforward, EMI reduction and other features. All of these features make the AD8556ACPZ-REEL7 ideal for a wide range of applications.
