What are the key features of TLC2272AMDG4?
- Dual rail-to-rail output operational amplifier enabling output swing within millivolts of both supply rails, maximizing dynamic range in single-supply 3.3V and 5V systems
- Ultra-low 0.8 nA maximum input bias current minimizing offset errors when driven from high-impedance sensor sources such as pH electrodes or photodetectors
- 70 dB minimum common-mode rejection ratio maintaining signal integrity in noisy industrial environments where common-mode interference is prevalent
What is TLC2272AMDG4 used for?
The TLC2272AMDG4 excels in precision signal conditioning for portable medical instrumentation, data acquisition front ends, and industrial sensor interfaces where single-supply operation and rail-to-rail output swing are required. Its ultra-low input bias current makes it a natural fit for high-impedance sensor buffering in pH measurement systems, photodiode amplifiers, and humidity sensor signal chains operating from 2.7V to 16V supplies.

Frequently Asked Questions
How low is the input bias current of the TLC2272AMDG4, and how does that benefit high-impedance sensor interfaces?
The maximum input bias current is 0.8 nA (0.0008 µA), which introduces negligible offset voltage error even when driven from source impedances in the megohm range, making it well suited for pH probes, ion-selective electrodes, and similar high-impedance transducer outputs.
What supply voltage range does the TLC2272AMDG4 support, and can it run from a single 3.3V rail?
The TLC2272AMDG4 operates from 2.7V to 16V on a single supply, which covers 3.3V and 5V systems directly; rail-to-rail output ensures the signal swing extends close to both ground and VDD, preserving full ADC input dynamic range.
What does the 70 dB CMRR specification mean for the TLC2272AMDG4 in a noisy industrial setting?
A 70 dB minimum CMRR means common-mode noise appearing equally on both inputs is attenuated by a factor of over 3000:1 at the differential output, which is critical for rejecting 50/60 Hz line interference and ground loop noise in industrial sensor front ends.
For a dual-channel audio or sensor design, how does using the TLC2272AMDG4 compare to using two single op-amps?
The TLC2272AMDG4 integrates 2 independent op-amp channels in a single 8-pin SOIC package, reducing component count and PCB area by roughly 50% versus two discrete single-channel devices, while both channels share the same low-bias-current CMOS process for matched performance.
