Product details
Overview
TLE2074IDW from Texas Instruments is a quad JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision signal conditioning. It delivers 10 MHz unity-gain bandwidth, 32 V/µs slew rate, ±19 V supply capability, 17 nV/√Hz input voltage noise at 1 kHz, and ±15 pA input bias current - enabling accurate amplification in oscilloscopes, electricity meters, and flight control units.
For engineers reviewing the TLE2074IDW datasheet, TLE2074IDW pinout, TLE2074IDW application, or TLE2074IDW equivalent, this device supports rail-to-rail input operation, wide common-mode range (±10.8 V at ±15 V supplies), and stable unity-gain performance - critical for high-fidelity data acquisition and low-distortion analog front-ends.
Technical Context
The TLE2074IDW employs Excalibur JFET-input architecture with on-chip Zener trimming for low offset drift, delivering DC precision alongside AC performance. Its fully differential input stage operates up to the supply rails, and its internal compensation ensures unity-gain stability without external components.
Designed for ±2.25 V to ±19 V dual-supply operation, it maintains 90 dB CMRR and 99 dB PSRR across temperature, with 56° phase margin and 300 kHz full-output-swing bandwidth - supporting fast settling (0.4 µs to 1 mV) in closed-loop configurations.
Key Specifications

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 |
|---|---|---|---|
| TL074CDR | Higher input noise (18 nV/√Hz), lower slew rate (13 V/µs), no guaranteed 10 MHz bandwidth. | Lower-cost general-purpose use; not specified for metrology-grade or high-speed acquisition. | Acceptable where bandwidth ≤ 3 MHz and noise ≤ 20 nV/√Hz suffices; lacks TLE2074IDW's rail-to-rail input and Zener-trimmed offset. |
| OPA4134UA | Lower noise (8 nV/√Hz), higher precision (250 µV max offset), but narrower supply range (±4 V to ±18 V) and no guaranteed −40°C to +85°C operation. | Better suited for audio and ultra-low-noise lab instruments; not qualified for industrial temperature range. | Preferred for audio or low-noise lab applications; TLE2074IDW remains optimal for wide-temp industrial metering and test equipment. |
Compared with TL074CDR and OPA4134UA, the TLE2074IDW uniquely balances 10 MHz bandwidth, rail-to-rail input, −40°C to +85°C qualification, and 17 nV/√Hz noise - making it the only option qualified for high-speed, high-accuracy, wide-temperature industrial instrumentation without trade-offs in speed or operating range.

FAQ
What is the maximum supply voltage rating for the TLE2074IDW?
The TLE2074IDW supports dual-supply operation from ±2.25 V up to ±19 V, with absolute maximum ratings of ±38 V on V+ and V− pins. This allows direct integration into legacy ±15 V systems and newer high-dynamic-range industrial rails without level-shifting circuitry.
Does the TLE2074IDW require external compensation for unity-gain stability?
No - the TLE2074IDW is internally compensated for unity-gain stability. Its phase margin is 56° at unity gain with 25 pF capacitive load, enabling direct use in gain-of-1 buffers, active filters, and integrators without adding external compensation networks.
What is the input offset voltage specification for the TLE2074IDW over temperature?
The TLE2074IDW has a maximum input offset voltage of 5 mV across the full operating range of −40°C to +85°C, with a typical value of 0.47 mV at 25°C and ±15°C. Its temperature coefficient is 3.2 µV/°C, ensuring predictable drift behavior in thermally varying environments.
Can the TLE2074IDW drive a 600 Ω load effectively?
Yes - the TLE2074IDW delivers ±14.5 V output swing into 20 mA loads at ±15 V supplies, which exceeds the ±10 V needed for 600 Ω (±6 V). Its open-loop output impedance is ~80 Ω at 1 MHz, and large-signal voltage gain remains >95 dB into 600 Ω, ensuring low distortion and minimal loading error.
Is the TLE2074IDW pin-compatible with other SOIC-14 quad op-amps like the TL074?
No - the TLE2074IDW uses a non-standard pinout: V− is on pin 4 and V+ on pin 11, whereas TL074 places V− on pin 4 and V+ on pin 8. Swapping them without layout revision causes functional failure; PCB redesign is required for substitution.
