Frequently Asked Questions
What is the input bias current of the TLC081IDG4?
The TLC081IDG4 features an extremely low typical input bias current of 0.05pA (50 femtoamperes) at 25°C due to its JFET input stage. This ultra-low bias current makes it ideal for amplifying signals from high-impedance sources such as piezoelectric sensors, photodiodes, and pH electrodes.
What is the CMRR of the TLC081IDG4?
The TLC081IDG4 achieves a common-mode rejection ratio (CMRR) of 110 dB nominal and a minimum of 80 dB, enabling excellent rejection of common-mode interference and noise in differential measurement applications such as bridge sensors and precision instrumentation circuits.
What supply voltage does the TLC081IDG4 operate from?
The TLC081IDG4 operates from a dual supply of ±8V (maximum ±8V, or 16V total supply), allowing a wide output voltage swing suitable for interfacing with both legacy ±15V systems and modern ±5V or single 12V supply designs with appropriate biasing.
What package is the TLC081IDG4 available in?
The TLC081IDG4 is available in an 8-pin SOIC (Small Outline Integrated Circuit) surface-mount package, which is one of the most common op-amp package formats. It is easy to hand-solder and compatible with standard automated PCB assembly processes.
