TL054 Enhanced JFET Input Quad Op-Amp

Contents hide

TL054 operational amplifiers offer improved dc and ac characteristics over the TL07x and TL08x families of BiFET operational amplifiers. The IC has range of working conditions a wide range of working voltages, and possesses direct interfacing capability with almost every PMOS, CMOS, and NMOS device. Moreover, the IC offers a wide array of features such as high noise immunity, ESD barring/reduction, and exceptionally low power dissipation.

Operational Amplifier

Operational Amplifiers are basically voltage amplifying devices designed to be used with components like capacitors and resistors. They serve as the core part of any analog device. Feedback components like capacitors and resistors are used to determine the operation of the amplifier. The amplifier can perform many different operations (resistive, capacitive, or both), giving it the name Operational Amplifier. Op-amps are linear devices that are ideal for DC amplification and are used often in signal conditioning, filtering or other mathematical operations

Application

analog thermometer
By combining a current source that does not vary over temperature with an instrumentation amplifier, a precise analog thermometer can be built . Amplifier U1A and IC1 establish a constant current through the temperature-sensing diode D1. For this section of the circuit to operate correctly, the TL05x must use split supplies and R3 must be a metal-film resistor with a low temperature coefficient.
