Frequently Asked Questions
What bias current does TL071HIDCKR offer and why does it matter for high-impedance sensor interfaces?
TL071HIDCKR has a maximum input bias current of 0.005 µA and a typical value of 0.00012 µA at 25°C. This ultra-low current prevents loading high-impedance sources such as pH electrodes and photodiodes, maintaining measurement accuracy without signal attenuation errors common in BJT-input amplifiers.
How does the 105 dB CMRR of TL071HIDCKR improve performance in differential measurement circuits?
With a 105 dB common-mode rejection ratio, TL071HIDCKR attenuates common-mode noise by over 177,000 times relative to differential signals. This is critical in industrial sensor bridges and audio balanced line receivers where 50 Hz or 60 Hz interference must be rejected while microvolt-level signal differences are accurately amplified.
When should a designer choose TL071HIDCKR in SOT-23-5 over a larger SOIC package for board-space savings?
The SOT-23-5 package of TL071HIDCKR occupies only about 2.9 mm x 1.6 mm of PCB area, roughly 6 times smaller than an SOIC-8 footprint. Choosing SOT-23-5 is advantageous in portable medical devices, wearables, and compact IoT nodes where each square millimeter of board space reduces product size and cost.
What supply voltage range does TL071HIDCKR support and which portable applications benefit most?
TL071HIDCKR operates from ±2.25V to ±18V dual supply or 4.5V to 36V single supply. Battery-powered instruments running from a 9V or ±12V rail gain full dynamic range, while single 5V USB-powered designs can use the TL071 in rail-to-rail output configurations to maximize output swing within the 5V window.
