TL084BMDT

Instrumentation, Op Amps, Buffer Amps Overview

The TL084BMDT is a quad JFET-input operational amplifier manufactured by STMicroelectronics. It integrates four high-speed amplifiers in a single monolithic IC, featuring low input bias current and offset voltage. The device operates within a supply voltage range of 6 V to 36 V (single) or ±3 V to ±18 V (dual). Key electrical parameters include a gain-bandwidth product of 4 MHz, a slew rate of 16 V/µs, an input offset voltage of 3 mV, and an input bias current of 200 pA. It provides 40 mA output current per channel and maintains operation across a temperature range of -40°C to +105°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'MDT' against official STMicroelectronics documentation to confirm package type and tape-and-reel specifications. Ensure compatibility with required operating temperatures and supply voltage ranges. Cross-reference datasheet revisions for any changes in electrical characteristics or pinout definitions before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high input impedance and low bias current are critical for signal integrity. The quad configuration reduces board space compared to single op-amps. Consider the 4 MHz bandwidth and 16 V/µs slew rate for moderate-speed applications. Verify that the SOIC-14 or similar surface-mount package fits the design constraints.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the TL084 family of general-purpose JFET quad operational amplifiers. The 'B' suffix typically denotes a specific performance grade regarding offset voltage and bias current compared to standard variants.
