Frequently Asked Questions

What is the input bias current specification of the TLC272AIDG4?

The TLC272AIDG4 has a maximum input bias current (IIB) of 60pA (0.00006 µA) at 25°C, which is extremely low due to its CMOS input stage. This ultra-low bias current makes it ideal for high-impedance source applications such as photodiode amplifiers, pH sensors, and precision charge amplifiers where leakage current would cause significant measurement errors.

What supply voltage range does the TLC272AIDG4 operate on?

The TLC272AIDG4 operates on a single supply from 3V to 16V or dual supplies from ±1.5V to ±8V. This wide voltage flexibility allows it to be used in both low-power 3.3V battery applications and traditional ±15V industrial analog systems, making it a versatile choice for multi-rail designs and portable instrumentation.

How many op-amp channels are in the TLC272AIDG4 and what package does it use?

The TLC272AIDG4 contains two independent op-amp channels (dual configuration) in an 8-pin SOIC package (JEDEC R-PDSO-G8). The small outline package offers a compact PCB footprint and is compatible with standard SMT assembly processes, making it suitable for space-constrained PCB designs.

What is the CMRR of the TLC272AIDG4 and why does it matter?

The TLC272AIDG4 has a common-mode rejection ratio (CMRR) minimum of 65dB and typically 80dB. High CMRR ensures that signals common to both inputs (such as power supply noise or ground shifts) are rejected while differential signals are amplified accurately, which is critical in differential sensor readout circuits and noisy industrial environments.

What are the main applications for the TLC272AIDG4 and are there pin-compatible alternatives?

The TLC272AIDG4 is used in active filters, integrators, sample-and-hold circuits, photodiode amplifiers, and precision instrumentation front-ends. Pin-compatible alternatives include the TLC272C (commercial grade), TLC272M (military grade), and the LMC6482 from Texas Instruments. The TLC272AI designates the industrial temperature grade (-40°C to 85°C), providing reliable operation across extended temperature ranges.
