1. Pre-Lab Introduction
... 1. Construct the circuit shown in Figure 7-1. Use ± 15 V supplies for the op-amp and a load resistance of 2.4 k-Ohms. 2. Verify the operation of the circuit using a 500 mV peak, 50 Hz sinewave as the input signal. Be sure to design the "gain" such that the output does not saturate. 3. Repeat step 2 ...

a High Speed, Low Power Dual Op Amp AD827
... The AD827 is a dual version of Analog Devices’ industrystandard AD847 op amp. Like the AD847, it provides high speed, low power performance at low cost. The AD827 achieves a 300 V/µs slew rate and 50 MHz unity-gain bandwidth while consuming only 100 mW when operating from ± 5 volt power supplies. Pe ...

band-pass filter
... A second-order band pass filter is to be constructed using RC components that will only allow a range of frequencies to pass above 1kHz (1,000Hz) and below 30kHz (30,000Hz). Assuming that both the resistors have values of 10kΩ´s, calculate the values of the two capacitors required ...
