Product details
Overview
TLE2074IDWR from Texas Instruments is a quad-channel JFET-input operational amplifier optimized for high-voltage, low-noise precision signal conditioning in industrial and test equipment. It delivers ±19V supply operation, 10MHz unity-gain bandwidth, 32V/μs slew rate, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate amplification of fast, low-amplitude signals in oscilloscopes and digital multimeters.
For engineers reviewing the TLE2074IDWR datasheet, TLE2074IDWR pinout, TLE2074IDWR application, or TLE2074IDWR equivalent, this device is selected for designs requiring rail-to-rail input capability, low bias current (±15pA), wide common-mode range (±10.9V at ±15V supplies), and stable unity-gain performance without external compensation.
Technical Context
The TLE2074IDWR implements a high-slew-rate JFET-input stage with on-chip Zener trimming for offset voltage control, supporting differential inputs up to the supply rails. Its internal architecture enables stable operation across ±2.25V to ±19V supplies while maintaining low noise and high DC precision.
It features a fully compensated design with 56° phase margin at unity gain and operates over −40°C to +85°C. The device exhibits 100MΩ common-mode input resistance and 6TΩ differential input resistance, making it suitable for high-impedance sensor interfaces and precision integrators.

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CDR | Higher input offset (15mV max), higher noise (18nV/√Hz), lower slew rate (13V/μs), same SOIC-14 package. | Less suitable for precision low-noise applications like DMMs or oscilloscope front-ends; acceptable for general-purpose industrial signal buffering. | Select TL084CDR only when cost is primary constraint and 10MHz bandwidth/low-noise performance is not required. |
| OPA4134UA | Lower noise (8nV/√Hz), lower VIO (1mV max), higher price, same SOIC-14 footprint but different pinout (non-compatible). | Better suited for ultra-low-noise audio or medical instrumentation; requires PCB redesign due to pinout mismatch. | Choose OPA4134UA only if noise budget demands <10nV/√Hz and layout revision is feasible. |
Compared with TL084CDR and OPA4134UA, the TLE2074IDWR provides optimal balance of low noise (17nV/√Hz), high slew rate (32V/μs), rail-to-rail input, and guaranteed −40°C to +85°C operation - making it the preferred choice for industrial test equipment where performance and reliability are prioritized over lowest cost or absolute lowest noise.

FAQ
What is the maximum supply voltage for the TLE2074IDWR?
The TLE2074IDWR supports a total supply voltage range of ±2.25V to ±19V, meaning the maximum differential supply is 38V. This allows operation in legacy ±15V systems and high-voltage industrial applications without external level-shifting circuitry. Absolute maximum ratings specify VCC+ up to +38V relative to VCC−, but recommended operation stays within ±19V for reliability and specified performance.
Does the TLE2074IDWR require external compensation for unity-gain stability?
No, the TLE2074IDWR is internally compensated and unity-gain stable. Its phase margin is specified at 56° under standard test conditions (CL = 25pF, RL = 2kΩ), ensuring stable closed-loop operation with gain ≥1 without adding external capacitors or resistors. This simplifies design in applications like voltage followers and active filters where minimal external components are desired.
What is the input bias current specification for the TLE2074IDWR at 85°C?
At +85°C, the TLE2074IDWR has a maximum input bias current of ±10nA per input, as confirmed by the TLE2074I electrical characteristics tables. This value reflects worst-case behavior across the full −40°C to +85°C operating range and remains significantly lower than bipolar-input op-amps, preserving accuracy in high-impedance sensor interfaces even at elevated temperatures.
Can the TLE2074IDWR drive a 600Ω load effectively?
Yes, the TLE2074IDWR can drive a 600Ω load with full output swing and specified performance. At ±15V supplies and 25°C, it delivers ±14.5V output swing into 20mA (equivalent to 725Ω), and its short-circuit output current is ±65mA. Driving 600Ω results in ~25mA peak current - well within safe operating limits and supported by the device's 10.6MHz bandwidth and 32V/μs slew rate for dynamic loads.
Is the TLE2074IDWR pinout compatible with other quad op-amps in SOIC-14 packages?
No, the TLE2074IDWR uses a non-standard SOIC-14 pinout optimized for quad JFET-input operation: pins 1/5/8/12 are inverting inputs, 2/6/9/13 are non-inverting inputs, and 3/7/10/14 are outputs, with VCC− on pin 4 and VCC+ on pin 11. This differs from industry-standard pinouts (e.g., TL084, LM324), so direct replacement requires PCB layout modification unless verified as pin-compatible in the target application.
