Linear - Amplifiers - Instrumentation, OP Amps, Buffer Amps

The PA85M is an instrumentational amplifier that is used primarily for automated test and measurement equipment, industrial and consumer amplifiers, as well as medical and scientific instrumentation. It is a high performance, low power, cost effective amplifier with a wide range of applications. This amplifier provides excellent linearity and low distortion characteristics, making it an ideal choice for high-end applications.The PA85M device consists of three sections – power amplifier, driver amplifier and input buffer – in a single integrated circuit. The power amplifier section consists of a pair of operational amplifiers (op-amp) that provide the high input impedance, low output resistance, and low noise performance. The driver amplifier section is a common-source, class A amplifier that is designed to drive either a load or a capacitive load, depending on its application. The input buffer section offers an adjustable gain that varies according to the input voltage.The PA85M operates in the linear mode of amplification. It is designed primarily for applications requiring low-distortion reproduction of audio or other signals. It is able to provide a wide range of gain settings, with gain ranging from zero to infinity. The most common application for the PA85M is an audio preamp, providing low-distortion amplification of mic and line level signals.The PA85M uses a class A amplifier configuration to minimize distortion and noise. The bias of the PA85M is accomplished using a cascade of three resistors and an adjustable current source. When properly biased, the amplifier has a gain of greater than one. This allows the PA85M to deliver a large output voltage swing while still remaining within the linear region of operation.The PA85M also offers a high common-mode rejection ratio (CMRR) and a low output impedance, thus providing superior sound quality. The CMRR helps reduce noise, hum, and other effects that can be picked up from ground loops. The low output impedance ensures that the PA85M is not affected by capacitive loads. This ensures a low output impedance across the operating range, which in turn reduces the susceptibility to external noise.The PA85M also features an adjustable current limit that protects the device from excessive currents that could result in damage. The current limit prevents the device from drawing too much current from the power supply, preventing permanent damage to the unit. A thermal overload protection circuit is also built into the device which will trip the device off if it reaches a certain temperature.In conclusion, the PA85M is an excellent choice for a wide range of applications due to its low distortion and low power consumption. It is well suited for applications requiring a high-end performance, such as audio preamps, as well as for high and low frequency loop gain instrumentation. The adjustable gain and current limit ensure that the device provides superior performance in all its intended applications, while the thermal overload and common-mode rejection ratio provide enhanced protection against the risks of damage.
