What are the key features of TLC27L4CDG4?
- Ultra-low input bias current of 0.6 pA maximum enables accurate signal conditioning from high-impedance sources such as pH electrodes and photodiodes without loading error
- Wide single-supply range of 3 V to 16 V and rail-to-rail input common-mode voltage allows flexible integration in both 3.3 V and 5 V or 12 V systems
- 65 dB minimum CMRR (97 dB typical) rejects common-mode noise in industrial sensor and instrumentation amplifier configurations
- Quad op-amp in a compact 14-pin SOIC package reduces BOM and board area compared to four separate single-channel amplifiers
What is TLC27L4CDG4 used for?
TLC27L4CDG4 is well suited for precision analog front ends in data acquisition systems, medical instrumentation, and sensor signal conditioning where its 0.6 pA input bias current prevents signal loading on high-impedance transducers such as pH probes and capacitive pressure sensors. The quad channel count and wide supply range from 3 V to 16 V make it practical for active filter banks, transimpedance amplifier arrays, and multi-channel audio processing in battery-powered or 12 V industrial equipment. Its CMOS input stage also reduces power consumption compared to bipolar-input alternatives in always-on monitoring applications.

Frequently Asked Questions
What is the input bias current of TLC27L4CDG4, and why does it matter for sensor interfaces?
TLC27L4CDG4 has a maximum input bias current of 0.6 pA (0.0006 µA). This extremely low current prevents voltage errors from building up across high-source-impedance sensors such as pH electrodes, capacitive sensors, or pyroelectric detectors, keeping measurement error below 1 mV even with source impedances above 1 GΩ.
Over what supply voltage range does TLC27L4CDG4 operate, and can it run from a single 5 V rail?
TLC27L4CDG4 operates from a single supply of 3 V to 16 V or a dual supply of ±1.5 V to ±8 V. It runs directly from a 5 V rail and is also compatible with 3.3 V systems, making it a flexible choice for microcontroller-based data acquisition boards without requiring a separate bipolar supply.
What is the CMRR specification of TLC27L4CDG4, and how does it benefit differential signal acquisition?
TLC27L4CDG4 specifies a minimum CMRR of 65 dB and a typical CMRR of 97 dB. In an instrumentation amplifier or differential analog front end, this level of common-mode rejection suppresses 50 Hz or 60 Hz power-line noise picked up on long sensor cables, allowing accurate millivolt-level differential signal recovery.
How does using the quad TLC27L4CDG4 compare to four individual single-channel op-amps in a 4-channel filter design?
Using TLC27L4CDG4 consolidates 4 op-amp channels into a single 14-pin SOIC footprint, reducing PCB area by approximately 60% versus four SO-5 or SOT-23 single-channel packages. BOM line items drop from 4 op-amps to 1, and shared decoupling reduces the passive component count, lowering total cost in 4-channel active filter or buffer circuits.
