Overview
The TLV272CDRG4, produced by Texas Instruments, is a low-power, wide-bandwidth operational amplifier (opamp) that belongs to the TLV27x family. This device operates from a supply voltage range of 2.7 V to 16 V and is specified over an extended industrial temperature range from –40°C to +125°C. It is designed to provide a rail-to-rail output, making it an ideal alternative to the TLC27x family for applications requiring full output swing. The TLV272 is particularly suited for battery-powered systems and high-impedance sensor interfaces due to its low power consumption and high slew rate.
