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

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

The LM340-XX are three terminal 1.0A positive voltage regulators with preset output voltages of 5.0V or15V. The LM340 regulators are complete 3-terminal regulators requiring no external components fornormal operation. However by adding a few parts one may improve the transient response provide for avariable output voltage or increase the output current. Included on the chip are all of t

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

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
