There are three TL082 OP-Amp
ICs has two amplifiers, which are labelled A and B. Thus 1A and 1B are the two
OP-AMps on OP-AMP IC 1, etc. The six OP-amps are categorized as below.
Thus, the OP-amps are marked TYPE I, TYPE II and TYPE III on the board. The
OP-Amps marked TYPE I can be connected in the inverting configuration only.
With the help of connectors, either resistors or capacitors can be used in the
feedback loop of the amplifier. There are two such TYPE I amplifiers. There
are two TYPE II amplifiers which can be configured to act as inverting or non-
inverting. Finally, we have two TYPE III amplifiers which can be used as voltage
buffers.
Three analog multipliers
precision analog multipliers from Texas Instruments (MPY634). Each
multiplier is a 14-pin IC and operates on internally provided ±10V supply.
There are two digital-to-analog converters (DAC)
kit, labeled DAC I and DAC II. Both the DACs are DAC7821 from Texas
Instruments. They are 12-bit, parallel-input multiplying DACs which can be
used in place of analog multipliers in circuits like AGC/AVC. Ground and power
supplies are provided internally to the DAC. DAC Logic Supply Jumper can
be used to connect logic power supplies of both DAC I and DAC II to either

LDO or DC/DC converter located on the board. Using Tri-state switches you
can set 12-bits of input data for each DAC to desired value. Click the Latch
Data button to trigger Digital-to-analog conversion.
We have included a
converter
converter provides an output of 3.3V over a wide input range
of 5.5-15V at output currents ranging from 0.125A to 2.5A.
Using Vout SEL jumper you can select output voltage to be either 5V or
3.3V. Another jumper allows you to select whether input voltage is provided
from the board (+10V), or externally using screw terminals.
We have included
designing an LDO regulator (Experiment 10), or custom experiments.
A specialized LDO regulator IC
board, which can provide a constant output voltage for input voltage ranging
from 5.5V to 11V. Ground connection is internally provided to the IC. Using
ON/OFF jumper you can enable or disable LDO IC. Another jumper allows
you to select whether input voltage is provided from the board (+10V), or
externally using screw terminals.
There are two 1kX trimmers
to obtain a variable voltage if needed for a circuit. The potentiometers are
labeled P1 and P2. These operate respectively in the range 0V to +10V, and
-10V to 0V.
The kit has a
ICs on the board are internally connected to power supply. Please refer to
Appendix D for schematics of ASLK PRO.
We have included
rectifiers in custom laboratory experiments.
