ALD2711PAL is a precision linear amplifier designed to provide a highly accurate, wide range closed loop DC gain instrumentation preamplifier with adjustable gain. The amplifier consists of two separate differential input stages with a gain of 18 dB and a low noise differential output system. The voltage gain can be adjusted with a resistive network and the gain can be adjusted from 0 to 126 dB. The amplifier requires a +20 VDC supply and it produces a maximum output of +4.5V for single-ended operation.

The device uses bipolar NPN transistors for low noise and low bandwidth applications. They have been designed for instrumentation, measurement and control applications requiring high accuracy and small size. They provide a wide range of gain, low offset voltage and high common-mode rejection ratio of 126 dB. The active parts are low-noise PNP transistors.

The ALD2711PAL features a wide range differential input stage with a low noise, low distortion output system. The amplifier allows for a wide range of gain, adjustable from 0 to 126 dB. The gain can be adjusted using a resistor network and it may be set at 0 to 62 dB, 0 to 92 dB, 0 to 102 dB or 0 to 126 dB. The ALD2711PAL also features a low-noise operational amplifier circuit. This op amp can be used for buffering, filtering and signal conditioning.

The ALD2711PAL is built around two low-noise PNP transistors, which are protected by an on chip ESD protection. The amplifier is provided with an integrated load resistor and a temperature compensation diode. It also includes a temperature sensor to detect and prevent device failure. In addition, the amplifier is protected against breakdown, short circuit and external shorts.

The ALD2711PAL is typically used in applications such as video cameras, DVRs, digital imaging, remote control, medical imaging and instrumentation. It can be used as a sensor amplifier, preamplifier, signal conditioning amplifier and as a signal tracking amplifier. It can also be used in a wide range of audio and music applications. It is ideal for applications that require low noise performance and high accuracy.

In operation, the ALD2711PAL amplifies input signals by adding the gain level set by the user. The input signal is first passed through the differential input stage which provides a gain of 18 dB. The signal is then passed through the low-noise operational amplifier circuit. The output of the amplifier is adjusted with a resistor network to the required gain level. The amplifier features a high common-mode rejection ratio of 126 dB, which ensures that noise signals are not amplified and the desired signal is presented with minimal distortion.

The ALD2711PAL is a precision linear amplifier designed for accurate, wide range closed loop DC gain instrumentation preamplifier with adjustable gain. Its wide range of gain makes it ideal for a wide range of applications such as video cameras, DVRs, digital imaging, remote control, medical imaging and instrumentation. Its integrated load resistor, temperature sensor and ESD protection make it a reliable and accurate device for a variety of signal conditioning applications.
