Chapter 1 Introduction This user’s guide describes the universal operational amplifier single, dual, quad (SOIC) evaluation module (EVM) with shutdown (SLOP248). The EVM simplifies evaluation of Texas Instruments surface-mount op amps with or without shutdown feature. Topic Page Design Features .
Design Features 1.1 Design Features The EVM board design allows many circuits to be constructed easily and quickly. There are three circuit development areas on the board, and each uses IC amplifiers in the SOIC package. Area 100 is for a single operational amplifier (op amp), with or without shutdown.
Chapter 2 Evaluation Module Layout This chapter shows the universal operational amplifier single, dual, quad (SOIC) evaluation module (EVM) with shutdown board layout, schematics of each area, and describes the relationships between the three areas. Topic Page Physical Considerations ........2–2 Area 100—Single Device SOIC .
If through hole is desired, the TLV431ACLP, TLV431AILP, TL431CLP, TL431ACLP, TL431ILP, or TL431AILP adjustable shunt regulators can be used. Refer to Texas Instruments’ Power Supply Circuits Data Book (literature number SLVD002) for details on usage of these shunt regulators.
Physical Considerations 2.2 Area 100—Single Device SOIC Area 100 uses 1xx reference designators, and is compatible with a single op amp, with or without shutdown, packaged as an 8-pin SOIC. This surface-mount package is designated by a D suffix in TI part numbers, as in TxxxxCD, TxxxxID, etc.
Physical Considerations 2.3 Area 200—Dual Device SOIC Area 200 uses 2xx reference designators, and is compatible with dual op amps, with or without shutdown, packaged as an 8-pin (without shutdown) or 14-pin (with shutdown) SOIC. This package is designated by a D suffix in TI part numbers, as in TxxxxCD.
Physical Considerations 2.4 Area 300—Quad Device SOIC Area 300 uses 3xx reference designators, and is compatible with quad op amps, with or without shutdown, packaged in a 14-pin (without shutdown) or 16-pin (with shutdown) SOIC. This surface-mount package is designated by a D suffix in TI part numbers, as in TxxxxID.
General Power Dissipation Considerations 2.5 General Power Dissipation Considerations For a given , the maximum power dissipation is shown in Figure 2–4 and is calculated by the following formula: –T Where: = Maximum power dissipation of Txxxx IC (watts) = Absolute maximum junction temperature (150 C) = Free-air temperature ( C) = Thermal coefficient from junction to case = Thermal coefficient from case to ambient air ( C/W)
Chapter 3 Example Circuits This chapter shows and discusses several example circuits that can be constructed using the universal operational amplifier EVM. The circuits are all classic designs that can be found in most operational amplifier design books. Topic Page Schematic Conventions .
Schematic Conventions 3.1 Schematic Conventions Figures 3–1 through 3–6 show schematic examples of circuits that can be constructed using the universal operational amplifier EVM with shutdown.
