. J Semiconductor S r LH0020/LH0020C High Gain Operational Amplifier 3 General Description Features The LH0020/LH0020C is a general purpose operational ™ Low offset voltage typically 1.0 mV at 25°C over the amplifier designed to source and sink 50 mA output cur- entire common-mode voltage range rents. In addition to its high output capability, the LHOO20/ = Low offset current typically 10 nA at 25°C for the LH0020C exhibits excellent open loop gain, typically in ex- LH0020 and 30 nA for the LHO020C cess of 100 dB. The parameters of the LH0020 are guaran- = Offset voltage is adjustable to zero with a single poten- teed over the temperature range of —55°C to + 125°C and tiometer +5V < Vg < +22V, while those of the LHOO20C are guar- @ +44V,50 mA output capability anteed over the temperature range of 0°C to +85°C and +5V < Vg < +18V. Output current capability, excellent input characteristics, and large open loop gain make the LH0020/LH0020C suit- able for application in a wide variety of applications from precision DC power supplies to precision medium power comparator.
