Op-Amp used as Scaler, Summer and Voltage Follower with Power Supply Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12316
Indian Lab Suppliers supplies the Op-Amp used as Scaler, Summer and Voltage Follower with Power Supply (Product ID: 12316) as part of its electronics engineering lab equipment range. It combines three op-amp circuits on one board: a scaling amplifier with offset, a summing amplifier and a voltage follower.
Quick Answer
The scaling amplifier can be set for a direct or inverse transfer function with a positive or negative DC offset; the summer adds several DC inputs; and the voltage follower gives unity gain with very high input impedance. Three 0-10 V DC (50 mA) variable supplies act as inputs, and two 3½-digit digital panel meters (0-20 V) read input and output. Two IC 741s and two potentiometers are fitted, powered by an internal ±15 V DC, 50 mA supply. A 3¾-digit DMM, audio sine-wave generator and 20 MHz CRO are needed for AC tests. The unit measures about 412 x 150 x 310 mm and weighs about 5 kg.
