Overview
The TL052CDR is a dual, JFET-input operational amplifier produced by Texas Instruments. It is part of the TL05x series, which offers improved DC and AC characteristics over the TL07x and TL08x families of BiFET operational amplifiers. The TL052CDR is known for its high slew rate, low offset voltage, and high input impedance, making it suitable for applications requiring precision and high AC response.
This amplifier is available in an 8-pin SOIC (D) package and operates within a temperature range of 0°C to 70°C. It is pin-compatible with the TL07x and TL08x, allowing for easy upgrades in existing circuits or optimal performance in new designs.
