LMT1097 is a precision operational amplifier with an 8 – pin industry-standard configuration. The IC features a low offset-voltage temperature coefficient, high gain, low supply current, and low noise. The IC is available in an 8 – pin hermetically sealed dual inline IC packaging (DIP). LT1097 offers many different features such as high gain current and low voltage noise, etc.
Precision operational amplifier
A Precision operational amplifier is an operational amplifier with better design specifications and topology than the conventional op-amp. Precision Op-amps are more accurate than your average general-purpose op-amps. In terms of design topology, Precision amplifiers have a better precision offset, zero-drift over time, lower internal noise (nV/√Hz), and input bias current. On the component scale, they have precise matching resistors etched in the substrate at the chip level.
For Example; a LM741 op-amp, has an offset voltage of 5mV. The offset voltage signifies the voltage that the user has to apply between the +ve and -ve of the IC, in order to get an output of 0V. On configuring the op-amp to operate at a gain of 100. The gain will not only multiply the input signal, but it will also multiply the offset voltage. This will result in the output voltage being off-value by a factor of +/-0.5V. On considering the OP177; a precision op-amp, with an offset voltage of 25uV. The same gain value of 100, would produce an error of only 2.5mV in a signal that has been amplified by a factor of 100.
