Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'DG4' indicates tape and reel packaging as documented in the datasheet ordering options. Confirm the 'I' suffix corresponds to the extended industrial temperature range of -40°C to 125°C. Ensure the manufacturer is identified as Texas Instruments. Cross-reference the part number against the latest Package Option Addendum for accurate pinout and footprint details before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high output drive current and wide bandwidth in a single-supply environment. It serves as an upgrade path for BiFET users transitioning to single-supply systems. Consider the 14-pin SOIC package for surface-mount assembly. Evaluate the trade-off between the 10 MHz bandwidth and the 1.9 mA per channel supply current based on power constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

The TLC084AIDG4 belongs to the TLC08xA family of wide-bandwidth, high-output-drive single-supply operational amplifiers. This family utilizes TI's patented LBC3 BiCMOS process. It is designed to replace older BiFET amplifiers like the TL08x series, offering improved bandwidth and lower noise while maintaining compatibility with existing designs through familiar features such as offset nulling pins.
