SLVU006A Datasheet, PDF (8/28 Pages) Texas Instruments – UNIVERSAL OPERATIONAL AMPLIFIER EVALUATION MODULE

Design Features
1.1 Design Features
The evaluation module board design allows many different circuits to be
constructed easily and quickly. The board has four separate circuit
development areas that can be snapped apart and separated. Areas 100 and
200 are for dual op amps in the SOIC and TSSOP/MSOP packages. Areas 300
and 400 are for SOT23–5 single operational amplifier packages. A few
possible circuits are listed below:
J Voltage Follower
J Noninverting Amplifier
J Inverting Amplifier
J Simple or Algebraic Summing Amplifier
J Difference Amplifier
J Current-to-Voltage Converter
J Voltage–to-Current Converter
J Integrator/Low-Pass Filter
J Differentiator/High-Pass Filter
J Instrumentation Amplifier
J Sallen-Key Filter
The EVM PCB is of two-layer construction, with a ground plane on the solder
side. Circuit performance should be comparable to final production designs.
1.2 Power Requirements
The devices and designs that are used dictate the input power requirements.
Three input terminals are provided for each area of the board:
Vx+
GNDx
Vx–
Positive input power for area x00 i.e., V1+ ⇒ area 100
Ground reference for area x00 i.e., GND2 ⇒ area 200
Negative input power for area x00 i.e., V4– ⇒ area 400
Each area has four bypass capacitors, two for the positive supply, and two for
the negative supply. Each supply should have a 1-µF to 10-µF capacitor for low
frequency bypassing and a 0.01-µF to 0.1-µF capacitor for high frequency
bypassing.
When using single supply circuits, the negative supply is shorted to ground by
bridging Cx02 or Cx06, and power input is between Vx+ and GNDx. The
voltage reference circuitry is provided for single supply applications that
require a reference voltage to be generated.
