Core Features & Advantages
The TLC2252CD is the tube-packaged variant of the TLC2252CDR, offering identical electrical performance in SOIC-8 with tube packaging for prototyping and low-volume assembly.
- Primary Function: Dual-channel micropower rail-to-rail CMOS operational amplifier, tube-packed for low-volume manual assembly and prototyping, identical in function to the TLC2252CDR tape-and-reel version.
- Advantages:
- Identical electrical performance to TLC2252CDR — same 35μA/channel, 19nV/√Hz, 1pA bias current, and rail-to-rail I/O in a convenient tube package for bench and short-run production.
- Tube packaging for flexibility — 75-piece tubes suit prototyping, manual insertion, and low-volume builds without tape-and-reel minimums or feeder setup.
- Low 1pA input bias current — near-zero sensor loading for high-impedance piezoelectric and capacitive signal sources, matching the tape-and-reel variant specification for specification.
Typical Application Scenarios
- Industry: Consumer / Portable / Prototyping / Education
- Equipment: Evaluation boards, bench prototypes, educational lab kits, low-volume sensor modules
- Use Cases:
- Engineering prototyping and evaluation boards where tube packaging simplifies manual handling and small-bank soldering.
- Educational laboratory amplifier experiments demonstrating micropower and rail-to-rail output concepts.
- Low-volume specialty sensor modules requiring the same TLC2252 performance without tape-and-reel procurement minimums.
