Precision zero-drift amplifier in a through-hole package
The LTC1050CN8#PBF is a single zero-drift operational amplifier from Linear Technology, designed for applications that demand extremely low input offset voltage and minimal drift over temperature and time. With a typical offset of 0.5 µV and input bias current of 10 pA, this part is suited for precision DC measurement, thermocouple amplifiers, and medical instrumentation front-ends where accuracy cannot be traded off. The 2.5 MHz gain-bandwidth product and 4 V/µs slew rate provide enough bandwidth for low-frequency signal conditioning without sacrificing stability. Housed in an 8-DIP (0.300", 7.62 mm) through-hole package, it fits socketed or breadboard prototypes as well as production boards that favor hand-solderable DIP footprints. The supply range of 4.75 V to 16 V covers single-supply and split-supply rails common in industrial and lab equipment. Operating temperature from -40°C to 85°C covers industrial environments.
Zero-drift topology — what it means for your signal chain
The zero-drift architecture continuously auto-corrects the input offset, so the 0.5 µV typical offset stays flat across the temperature range and over years of operation. That matters for circuits like load-cell readouts, precision current shunts, or DAC output buffers where a few microvolts of drift would shift the system accuracy out of spec. The 10 pA input bias current also suits high-impedance sources — pH probes, photodiode preamps, or high-value resistive dividers — without needing a second buffer stage. The 1 mA supply current per amplifier keeps the thermal budget modest in multi-channel panels.
Slew rate and bandwidth — matching the signal
Gain-bandwidth product is 2.5 MHz and slew rate is 4 V/µs.
