Frequently Asked Questions
What are the key electrical specifications of the TLC27M4AIN?
The TLC27M4AIN features a maximum input offset voltage of 5000µV, a typical bias current of 0.00006µA (0.06nA) at 25°C with a maximum of 0.002µA, and a common-mode rejection ratio of 91dB typical and 65dB minimum. It uses a voltage-feedback architecture with internal frequency compensation.
What are the typical applications for the TLC27M4AIN?
The TLC27M4AIN is commonly used in precision signal conditioning, sensor interfaces, active filters, instrumentation amplifiers, and data acquisition systems. Its ultra-low bias current makes it especially suitable for high-impedance source applications, medical instrumentation, and battery-powered portable devices.
What package type does the TLC27M4AIN come in and is it RoHS compliant?
The TLC27M4AIN comes in a Dual-In-Line (DIP) package, which is convenient for prototyping and through-hole PCB assembly. It is RoHS compliant and Pb-free (Pbfree Code: Yes), making it suitable for environmentally conscious designs and meeting modern regulatory requirements.
How does the TLC27M4AIN compare to standard bipolar quad op-amps?
Compared to standard bipolar quad op-amps, the TLC27M4AIN uses a LinCMOS process that delivers significantly lower bias current (0.06nA vs. hundreds of nA for bipolar), reducing errors when interfacing with high-impedance sources. The trade-off is a slightly higher offset voltage, but the precision specifications still make it excellent for instrumentation and measurement applications.
