Overview
The TL054CDR is a quad operational amplifier from Texas Instruments, part of the TL05x series. This device is known for its high slew rate, low offset voltage, and high input impedance, making it suitable for a variety of applications requiring precision and high performance. The TL054CDR is housed in a 14-pin SOIC (D) package and is fully specified for operation at ±15 V and ±5 V supply voltages.
The TL05x series offers improved DC and AC characteristics compared to the TL07x and TL08x families of BiFET operational amplifiers. The on-chip Zener trimming of the offset voltage ensures precision grades as low as 1.5 mV, enhancing accuracy in DC-coupled applications. The BiFET process used in these amplifiers provides the high input impedance of JFET-input transistors without sacrificing the output drive associated with bipolar amplifiers.
