Frequently Asked Questions
What is the input bias current of the TLC072IDRG4 and why does it matter for high-impedance sensor interfaces?
The TLC072IDRG4 has an extremely low input bias current of 0.00005 µA at 25°C, which prevents significant loading on high-impedance signal sources such as piezoelectric sensors and pH electrodes. This characteristic preserves signal integrity and measurement accuracy in precision instrumentation and biomedical sensor front-end circuits.
How does the TLC072IDRG4 perform in noise-sensitive audio or measurement applications given its CMRR specification?
The TLC072IDRG4 achieves a common-mode rejection ratio of 95 dB typical and 80 dB minimum, effectively suppressing power supply noise and interference in differential signal paths. This makes it highly effective in audio preamplifiers, active filter stages, and precision ADC input buffers where noise rejection directly impacts output quality.
Which package does the TLC072IDRG4 use and what are its key physical dimensions for PCB layout planning?
The TLC072IDRG4 comes in an 8-pin SOIC (Small Outline IC) package, R-PDSO-G8, measuring approximately 5 mm x 4 mm with 1.27 mm pin pitch. This compact footprint integrates easily into dense PCB layouts for dual-channel amplifier circuits in portable instruments and consumer electronics.
For an industrial sensor signal chain operating between -40°C and 85°C, does the TLC072IDRG4 remain reliable?
Yes, the TLC072IDRG4 is rated for the industrial temperature range from -40°C to +85°C, ensuring stable amplifier performance with maintained CMRR above 80 dB and input offset voltage within 3000 µV across the full operating range. This reliability makes it suitable for harsh industrial measurement and control environments.
