What are the key features of TLC072CDGNG4?
- 100 pA maximum input bias current minimizes error in high-impedance sensor interfaces such as pH probes and photodiodes
- 80 dB minimum CMRR (95 dB typical) rejects common-mode noise in differential signal paths
- Wide ±4 V to ±8 V supply range with internal frequency compensation for stable single or dual-supply operation
What is TLC072CDGNG4 used for?
TLC072CDGNG4 is a strong choice for precision analog front-ends in data-acquisition systems, audio filter stages, and instrumentation amplifiers where the source impedance is high and low input bias current is critical. Its dual-amplifier configuration simplifies active filter implementations — such as dual Sallen-Key topologies — within a single 8-pin HVSSOP footprint. Industrial sensor interfaces and medical monitoring equipment also benefit from its 95 dB typical CMRR rejecting 50/60 Hz interference.

Frequently Asked Questions
How does the 100 pA maximum input bias current of TLC072CDGNG4 affect high-impedance sensor interface accuracy?
At 100 pA maximum bias current, a 10 MΩ source impedance introduces only 1 mV of offset-like error, well within the 3 mV input offset voltage spec. This makes TLC072CDGNG4 suitable for pH electrode buffers, photodiode transimpedance stages, and capacitive humidity sensors where source resistances can exceed 1 MΩ.
What supply voltage range does TLC072CDGNG4 support, and can it run from a single 5 V rail?
TLC072CDGNG4 operates on dual supplies from ±4 V to ±8 V (8 V to 16 V total). A single 5 V supply falls below the minimum 8 V total, so a split ±5 V or ±8 V supply is required. For single-supply 5 V designs, a different TI op-amp in the TLC07x family with rail-to-rail input would be a better choice.
For a second-order active low-pass filter centered at 10 kHz, what makes TLC072CDGNG4's dual configuration and HVSSOP package advantageous?
A second-order Sallen-Key or multiple-feedback low-pass filter at 10 kHz needs 2 op-amp stages. TLC072CDGNG4 provides both amplifiers in one 8-pin HVSSOP package measuring roughly 3 mm × 3 mm, cutting part count by half. The 95 dB typical CMRR also suppresses 50 Hz or 60 Hz power-line interference that would otherwise distort the passband.
