TL084CNSR

Instrumentation, Op Amps, Buffer Amps Overview

The TL084CNSR is a quad JFET-input operational amplifier from the Texas Instruments TL08xx family, housed in a 14-pin SOIC surface-mount package. It integrates high-voltage JFETs with bipolar transistors to deliver high slew rates and low input bias currents. The device operates on a single or dual power supply ranging from 7V to 36V (±3.5V to ±18V). Key electrical characteristics include a gain-bandwidth product of 3 MHz, a typical slew rate of 13 V/µs, and an input bias current as low as 30 pA. It features output short-circuit protection and is rated for operation between 0°C and 70°C.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• JFET input stage providing high input impedance and low input bias current

• Wide common-mode and differential voltage operating ranges
• Low power consumption with 1.4 mA per channel

Instrumentation, Op Amps, Buffer Amps Applications

• General-purpose analog signal processing circuits
• Audio preamplifiers and tone control stages
• Voltage followers and buffer amplifiers
• Active filters and integrators

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'SR' indicates tape-and-reel packaging when sourcing. Confirm the 'C' designation corresponds to the commercial temperature range (0°C to 70°C) rather than industrial or automotive grades. Ensure the supplier provides the official Texas Instruments datasheet Rev. O or later to validate pinout and electrical limits against counterfeit risks.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring high input impedance without the need for chopper-stabilized precision. It serves as a direct functional replacement for other quad JFET op-amps in the TL08x series. Consider the SOIC package constraints for thermal management if multiple channels are driven near maximum load. Verify that the required slew rate meets the signal frequency demands of the specific circuit design.

Instrumentation, Op Amps, Buffer Amps Part Context

The TL084CNSR belongs to the widely used TL08xx family of JFET-input operational amplifiers. This family is characterized by its compatibility with standard bipolar logic and its ability to operate over a wide voltage range. The 'CN' prefix typically denotes the PDIP package, while 'CNSR' specifies the SOIC surface-mount variant with reel packaging, maintaining identical electrical performance across the form factors.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Compatible substitutes include the TL084CDR and TL084IDR from Texas Instruments, which share the same quad JFET architecture. Other generic equivalents may exist, but verify pinout compatibility and electrical specifications such as input offset voltage and bandwidth before integration.
