Frequently Asked Questions
What is the input bias current of the TLC272BID?
The TLC272BID has a maximum input bias current (IIB) of 0.06 nA (60 pA) at 25°C, making it one of the lowest-bias CMOS op-amps available. This ultra-low bias current is critical for high-impedance sensor interfaces such as pH electrodes, photodiodes, and charge amplifiers where even picoamp-level currents would cause significant measurement error.
What are the typical applications for the TLC272BID?
The TLC272BID is commonly used in precision instrumentation amplifiers, active low-pass and band-pass filters, sensor signal conditioning for temperature and pressure transducers, photodiode current-to-voltage converters, and sample-and-hold circuits. Its dual channel configuration also suits differential amplifier designs in medical devices, industrial data acquisition systems, and portable battery-operated equipment.
What package does the TLC272BID come in and what are its supply voltage requirements?
The TLC272BID is housed in an 8-pin SOIC (Small Outline IC) package, which offers a compact footprint suitable for surface-mount assembly. It operates from a single supply of 3 V to 16 V or a dual supply of ±1.5 V to ±8 V, providing flexibility for both single-supply microcontroller-based systems and traditional dual-rail analog designs.
How does the TLC272BID compare to bipolar op-amps like the LM358?
Unlike bipolar op-amps such as the LM358, which have input bias currents in the range of 20–100 nA, the TLC272BID's CMOS input stage delivers bias currents as low as 0.06 nA—over 300 times lower. This makes it far superior for high-impedance applications. However, the TLC272BID may exhibit higher input offset voltage drift with temperature compared to precision bipolar devices, so the optimal choice depends on the specific accuracy and impedance requirements of the design.
