Staircase Generator (Using IC 555 and OP-AMP IC-741) Manufacturer,Supplier and Exporter in India
Product Code : SCL-EELE-12095
Indian Lab Suppliers supplies the Staircase Generator (Using IC 555 and OP-AMP IC-741) (Product ID: 12095) as part of its electronics engineering lab equipment range. It is a board for studying a free-running staircase waveform generator built from a 555 timer and two 741 op-amps.
Quick Answer
The 555 timer supplies a pulse train, and the op-amp stages turn each pulse into an equal voltage step, so the output climbs in a staircase and then resets to start again without an external trigger. Students view the staircase and the clock on a dual-trace CRO and relate step height and step count to the circuit values. The board has one 555, two 741s, a ±15 V, 60 mA regulated supply and runs on 230 V ±10%, 50 Hz mains.
