Frequently Asked Questions
What makes the TLV4111CDGN different from standard op-amps?
The TLV4111CDGN combines high output drive capability with an ultra-low input bias current of 25 fA at 25°C, a combination not commonly found in general-purpose op-amps. This makes it uniquely suited for applications that must both sense high-impedance signals accurately and drive low-impedance loads directly without additional buffers.
What is the input bias current of the TLV4111CDGN?
The TLV4111CDGN has a maximum input bias current of 100 fA and a typical value of 25 fA at 25°C. This extremely low bias current prevents loading of high-impedance sources such as pH electrodes, MEMS sensors, and precision voltage references in sensitive measurement applications.
What supply voltage does the TLV4111CDGN require?
The TLV4111CDGN is designed for low-voltage operation, typically running from a single supply in the range suitable for 3V to 5V systems. Its low-voltage architecture makes it compatible with modern microcontroller-based designs and battery-powered portable instruments without requiring a negative supply rail.
What package is the TLV4111CDGN available in?
The TLV4111CDGN is provided in an 8-pin SOIC (Small Outline IC) surface-mount package, which is widely used in industrial and consumer electronics for its balance of compact size, ease of hand-soldering during prototyping, and excellent thermal performance in final production assemblies.
What are typical applications for the TLV4111CDGN?
Typical applications include photodiode transimpedance amplifiers, electrochemical sensor interfaces, active filter stages in medical devices, precision instrumentation front ends, and motor control signal conditioning circuits where high output drive strength and low input leakage are simultaneously required for accurate, reliable performance.
