What is TLV272CDG4 used for?
The TLV272CDG4 is well-suited for battery-powered sensor nodes and portable medical devices that require two independent amplifier channels on a 2.7 V to 5 V single-supply rail, such as temperature transmitters, pressure sensor signal conditioners, and ECG front-ends. Its 3 MHz bandwidth and rail-to-rail output also make it a practical choice for active low-pass and band-pass filter stages in audio equipment, data-acquisition modules, and 4–20 mA industrial loop transmitters.

Frequently Asked Questions
What gain-bandwidth product does the TLV272CDG4 offer and what filter cut-off frequencies does that support?
The TLV272CDG4 has a 3 MHz gain-bandwidth product, allowing a unity-gain buffer stage or a low-gain amplifier to handle signals up to 3 MHz, and an active Sallen-Key low-pass filter with a gain of 10 dB to achieve a -3 dB corner frequency of about 300 kHz in audio and sensor applications.
How does the rail-to-rail output of the TLV272CDG4 benefit designs running from a 3.3 V single supply?
The rail-to-rail output can swing within 50 mV of both supply rails at light loads, effectively providing a 3.2 V peak-to-peak output swing on a 3.3 V supply, which maximises ADC input utilisation and avoids output clipping in 12-bit data acquisition systems with a 3.3 V reference.
Can the TLV272CDG4 operate reliably in industrial temperature environments?
Yes, the device is rated from -40°C to 125°C, and the 80 dB CMRR is maintained across that range, making it suitable for industrial transmitters, process control instruments, and factory automation sensors that experience wide ambient temperature swings between outdoor winter and hot machinery environments.
What is the input offset voltage specification for the TLV272CDG4 and how does it affect DC accuracy?
Maximum input offset voltage is 5 mV at 25°C, which introduces a DC error of 5 mV times the closed-loop gain; at a gain of 10, this results in a maximum 50 mV output error, acceptable for general-purpose sensor conditioning but worth noting for precision applications requiring better than 0.1% DC accuracy.
How does the TLV272CDG4 compare to a single-supply 5 V op-amp when used in a portable 3 V design?
With a 2.7 V minimum supply rating and rail-to-rail output, the TLV272CDG4 operates from two alkaline AA cells at end-of-life (down to 2.7 V total) without output headroom loss, whereas op-amps with a 5 V minimum supply would require boost regulation, adding cost and reducing battery runtime in portable sensor applications.
