1-1 Introduction 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 T exas Instruments surface-mount op amps with or without shutdown feature.
Design Features 1-2 Introduction 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.
2-1 Evaluation Module Layout 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.
Physical Considerations 2-2 Evaluation Module Layout 2.1 Physical Considerations The EVM board has three circuit development areas. Each area can be separated from the others by breaking along the score lines. The circuit layout in each area supports an op amp package, voltage reference, and ancillary devices.
Physical Considerations 2-3 Evaluation Module Layout 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 2-4 Evaluation Module Layout 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.
Physical Considerations 2-5 Evaluation Module Layout 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.
