Product details
Overview
TLE2064MWB from Texas Instruments is a quad JFET-input operational amplifier optimized for low-power, high-output-drive precision analog signal conditioning in extended-temperature industrial and military systems. It delivers 2 MHz unity-gain bandwidth, 290 µA per channel supply current, ±12 V output swing into 600 Ω at ±15 V supplies, and on-chip zener-trimmed offset voltage (max 4 mV over −55°C to 125°C) - enabling dc-coupled sensor interfacing in rugged data acquisition front-ends.
For engineers reviewing the TLE2064MWB datasheet, TLE2064MWB pinout, TLE2064MWB application, or TLE2064MWB equivalent, key selection criteria include its BiFET architecture's high input impedance (>10¹² Ω), low 1/f noise (1.1 µVPP, 0.1–10 Hz), 70° phase margin into 600 Ω, and guaranteed operation across −55°C to 125°C with ±3.5 V to ±18 V dual supplies.
Technical Context
The TLE2064MWB uses Texas Instruments' Excalibur BiFET process to combine JFET input stages (for >10¹² Ω input resistance and sub-pA bias current) with bipolar output circuitry capable of sourcing/sinking ±80 mA and driving 100 Ω loads - a capability uncommon among low-power op amps. Its internal compensation ensures stability with capacitive loads up to 100 pF while maintaining 70° phase margin at unity gain into 600 Ω.
On-chip zener trimming enables precision DC performance (VIO ≤ 4 mV over full temperature range), while the quad configuration shares common supply pins (VCC+, VCC−) and includes no internal connections on unused offset null terminals - distinguishing it from single/dual variants like TLE2061M/TLE2062M that retain dedicated offset pins.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±3.5 V to ±18 V - supports wide-rail industrial power domains without external regulation |
| Unity-Gain Bandwidth | 2 MHz - enables stable amplification of audio-band and low-speed control signals |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CD | Higher supply current (1.4 mA/ch), wider offset range (15 mV max), no on-chip offset trim | Limited to commercial temp range (0°C to 70°C); unsuitable for extended-temperature deployments | Select when cost sensitivity outweighs precision and temperature range requirements |
| TLE2064ACN | Same die, plastic DIP (N) package; 0°C to 70°C rating; 2 mV max VIO at 25°C only | Lower reliability and moisture sensitivity; not qualified for aerospace/military use | Select for cost-sensitive commercial instrumentation where hermetic sealing is unnecessary |
Compared with TL084CD and TLE2064ACN, the TLE2064MWB provides superior DC accuracy over military temperature extremes and hermetic packaging for harsh environments - making it the only option qualified for deployed avionics and downhole oilfield electronics where long-term parameter stability is non-negotiable.

FAQ
What is the maximum operating temperature range for the TLE2064MWB?
The TLE2064MWB is fully specified from −55°C to +125°C, with absolute maximum ratings extending to −65°C storage and 150°C junction temperature. This makes it suitable for deployment in uncontrolled environments such as engine compartments, downhole tools, and outdoor military enclosures where ambient temperatures exceed commercial-grade limits.
Does the TLE2064MWB require external offset nulling components?
No. The TLE2064MWB uses on-chip zener trimming to achieve ≤4 mV input offset voltage over its full −55°C to 125°C operating range, eliminating the need for external potentiometers or trimming networks. Unlike earlier TLE206x variants (e.g., TLE2061x), the TLE2064MWB has no functional offset null pins - all NC pins are internally disconnected.
Can the TLE2064MWB drive a 100 Ω load effectively?
Yes. The TLE2064MWB is explicitly characterized into 100 Ω loads, delivering ±2.5 V output swing at ±5 V supplies and ±12 V at ±15 V supplies. Its bipolar output stage sources/sinks up to ±80 mA, ensuring stable operation without thermal shutdown or distortion - a key differentiator from standard low-power JFET op amps.
How does the TLE2064MWB compare to the TL084 in terms of noise performance?
The TLE2064MWB offers significantly lower 1/f noise: 1.1 µVPP (0.1–10 Hz) versus TL084's typical 2.5 µVPP. At 1 kHz, its 40–60 nV/√Hz input voltage noise is also 30% lower than TL084's 60–80 nV/√Hz. This advantage stems from TI's Excalibur BiFET process, which reduces flicker noise while retaining high input impedance.
Is the TLE2064MWB pin-compatible with other TLE206x quad op amps?
Yes - the TLE2064MWB shares the identical 14-pin W-package pinout with all TLE2064 variants (e.g., TLE2064ACN, TLE2064ID). However, it is not pin-compatible with dual (TLE2062) or single (TLE2061) versions, nor with TL084 due to differing offset null pin assignments. Always verify supply decoupling and layout per the W-package thermal requirements (10°C/W θJA).
