The MAX4071UA-T is an advanced instrumentation operational amplifier (in-amp) designed for precision and accuracy in the most demanding applications. It is ideal for precision and high-temperature applications. The in-amp has an extended common-mode voltage range, low offset voltage and drift, excellent linearity, and low current noise. Working Principle of MAX4071UA-T The MAX4071UA-T has a differential amplifier architecture with a wide differential voltage range of ±50V. This amplifier provides common-mode rejection (CMRR) up to ±110dB over the specified temperature range and power supply range. The input stage is a fully differential amplifier with an integrated pass-gate switch for ground-referenced inputs. The MAX4071UA-T’s architecture eliminates the need for a voltage-source termination resistor and reduces thermal EMFs. The input stage includes an on-board precision voltage reference (VREF) to minimize matching between different in-amps, providing excellent common-mode rejection. The MAX4071UA-T also includes a variable-gain amplifier (VGA) which can be used to adjust the gain of the amplifier over a wide range. The VGA can be programmed using external resistors or can be set using an external signal. The VGA allows the device to provide accurate signal conditioning and signal rejection in closed-loop applications.The MAX4071UA-T has adjustable output current and low-offset current capability. The output current of the device can be adjusted from 0.2mA to 1.0mA by changing the output current range (OCR) resistor. The low-offset current allows the device to operate with ultra-low offset voltage and drift. The output stage provides excellent linearity and low area spacing, making it ideal for applications that require low area spacing. The output stage also provides over voltage protection, providing added protection to the device.Application Fields of MAX4071UA-TThe MAX4071UA-T is designed for precision analog applications such as precision sensor interfaces, precision measurement architectures, and transconductance amplifiers. The device is ideal for industrial and laboratory use, as it has an extended operating temperature range of -40°C to +125°C. The MAX4071UA-T is also ideal for applications such as data converters, test instrumentation, strain gauge amplifiers, pressure transducer amplifiers, bridge amplifiers, and industrial controls. In addition, the device has a high common-mode rejection, low drifting, and excellent linearity, making it suitable for high-precision applications.ConclusionThe MAX4071UA-T is a high-performance instrumentation operational amplifier designed for the most demanding applications. Its features include an extended common-mode voltage range, low offset voltage and drift, excellent linearity, low current noise, adjustable output current, and low-offset current capability. The device is ideal for precision and high-temperature applications such as industrial and laboratory use. It is also suitable for applications such as data converters, test instrumentation, strain gauge amplifiers, pressure transducer amplifiers, bridge amplifiers, and industrial controls.
