MAX419ESD+T

MAX419ESD+T is a precision operational amplifier that features dielectrically isolated input. It is characterized by high multi-echo cancellation stability and low sourcing power of the analog input. This operational amplifier is suited for use in instrumentation and test equipment applications where precision and wide bandwidth operation is required.

Applications

MAX419ESD+T is specifically designed for demanding audio applications. Its wide bandwidth, precision and high multi-echo cancellation stability makes it ideal for use in audio mixing and synthesis applications, as well as in instrumentation and test equipment where accuracy and fast response time are required. This amplifier is also suitable for use in buffer amplifiers, linear control, and for monitoring and control of multiple loop stages.

Working Principle

The MAX419ESD+T provides buffered Differential Non-inverting (DN) outputs with a voltage gain of 1. It features adjustable current sources that eliminate loading effects. The input stage consists of two closely coupled NPN transistors, which provide low input bias current, high input resistance, and equal input bias current.

In addition, the MAX419ESD+T has an internal low pass filter that reduces noise and distortion. The amplifier also features an active electrical de-coupling system that is incorporated within the input stage. This reduces the effects of power supply and external noise on the inputs of the amplifier, making it remarkably stable with low input capacitance, low input bias current, and high impedance.

The MAX419ESD+T is a DC coupled amplifier, which means it can handle both AC and DC signals. It is designed to work with +V/-V power supplies and is capable of supplying up to 5mA of output current. The operational amplifier has a maximum supply voltage of +14V/-14V and a nominal supply voltage from +7V/-7V.
