This application note describes a monolithic operational amplifier which has input error currents in theorder of 100 pA over a в€’55В°C to 125В°C temperature range. Instead of FETs, the circuit used bipolartransistors with current gains of 5000 so that offset voltage and drift are not degraded. A powerconsumption of 1 mW at low voltage is also featured.A number of novel circuits that make use

Operational amplifiers are undoubtedly the easiest and best way of performing a wide range of linearfunctions from simple amplification to complex analog computation. The cost of monolithic amplifiers isnow less than $2.00, in large quantities, which makes it attractive to design them into circuits where theywould not otherwise be considered. Yet low cost is not the only attraction of monoli

It is well known that the voltage noise of an operational amplifier can be decreased by increasing the emitter currentof the input stage. The signal-to-noise ratio will be improved by the increase of bias, until the base current noise begins to dominate.

One of the most predictable non-linear elements commonly available is the bipolar transistor. Therelationship between collector current and emitter base voltage is precisely logarithmic from currentsbelow one picoamp to currents above one milliamp. Using a matched pair of transistors and integratedcircuit operational amplifiers it is relatively easy to construct a linear to logarithmic conv

Since the introduction of monolithic IC amplifiers there has been a continual improvement in DC accuracy.Bias currents have been decreased by 5 orders of magnitude over the past 5 years. Low offset voltagedrift is also necessary in a high accuracy circuits. This is evidenced by the popularity of low drift amplifiertypes as well as the requests for selected low-drift op amps. However until n

The availability of dual and quad packaged FET op amps offers the designer all the traditional capabilitiesof FET op amps including low bias current and speed and some additional advantages. The cost-peramplifieris lower because of reduced package costs. This means that more amplifiers are available toimplement a function at a given cost making design easier. At the same time the availab
