Frequently Asked Questions
How low is the TC913BCPA's input bias current, and why does it matter for high-impedance sensor interfaces?
The TC913BCPA has a typical input bias current of 0.00012 µA at 25°C and a maximum of 0.004 µA. Such low bias current is critical when interfacing with high-impedance sensors like pH electrodes or piezoelectric transducers, where significant error voltages would develop across source impedances with a conventional op-amp.
What CMRR does the TC913BCPA provide, and how does it benefit differential measurement circuits?
The TC913BCPA delivers a minimum common-mode rejection ratio of 100 dB and a typical CMRR of 110 dB. This high CMRR ensures that common-mode noise, such as 50 Hz or 60 Hz interference, is strongly rejected in differential measurement circuits like bridge amplifiers and precision instrumentation front ends.
Why choose the TC913BCPA's chopper-stabilized architecture over a standard op-amp for a DC precision weighing scale design?
Chopper stabilization in the TC913BCPA continuously cancels offset voltage errors through an internal switching mechanism, eliminating the slow drift over temperature that affects conventional op-amps. For a DC weighing scale with 24-bit ADC resolution, this ensures the amplifier's offset contributes less than 1 µV of error across a wide temperature range.
Is the TC913BCPA available in an 8-pin through-hole package, and what does this mean for prototyping and repair?
Yes, the TC913BCPA comes in an 8-pin PDIP (DIP-8) through-hole package. This format is convenient for breadboard prototyping, manual soldering during development, and field repair or replacement in industrial instruments without requiring specialized SMD rework equipment.
