Product details
Overview
TLE2071IDG4 from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers 10.6 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 signal conditioning in oscilloscopes, electricity meters, and flight control units.
For engineers reviewing the TLE2071IDG4 datasheet, TLE2071IDG4 pinout, TLE2071IDG4 application, or TLE2071IDG4 equivalent, this device is selected where rail-to-rail input operation, low 1/f noise, wide dynamic range, and stable unity-gain performance are required in industrial and aerospace instrumentation.
Technical Context
The TLE2071IDG4 uses Excalibur JFET-input architecture with on-chip Zener trimming for offset voltage stability across temperature. Its differential input stage operates up to the supply rails, supporting full-swing signal acquisition without clipping in high-common-mode environments.
Designed for unity-gain stability, it features a 56° phase margin with 25 pF capacitive load and delivers 300 kHz maximum output-swing bandwidth at ±15 V supplies - making it suitable for active filtering, sensor interfacing, and analog front-end buffering where DC precision and AC fidelity must coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±19 V - supports wide dynamic signal range in high-voltage industrial systems |
| Unity-Gain Bandwidth | 10.6 MHz - enables stable amplification of fast transients up to ~10 MHz without compensation |
| Slew Rate | 32 V/μs - preserves fidelity of 2–10 V step signals with sub-microsecond settling |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - critical for low-level sensor signal integrity in DMMs and metering |
| Input Bias Current | ±15 pA (typ) - minimizes error in high-impedance source interfaces like piezoelectric sensors |
| Common-Mode Input Range | Extends to within 0.8 V of rails at ±15 V - allows direct connection to unbuffered transducer outputs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1 nV/√Hz), lower offset (25 µV), but ±18 V max supply and SOIC-8 package only | Better for ultra-low-noise audio or precision DAC buffers; less suited for ±19 V rail operation | Select when noise dominates over supply headroom; verify thermal dissipation at 3.6 mA quiescent current |
| TL071CDR | Same family lineage, higher noise (18 nV/√Hz), wider offset spread (10 mV max), lower slew rate (13 V/μs) | Cost-optimized alternative for non-critical industrial signal conditioning where speed is not limiting | Choose for legacy designs or cost-sensitive BOMs; confirm CMRR (70 dB) suffices for noisy motor-drive environments |
Compared with OPA211IDR and TL071CDR, the TLE2071IDG4 uniquely balances ±19 V operation, 10.6 MHz bandwidth, and 17 nV/√Hz noise - making it the preferred choice for high-fidelity, high-supply-voltage analog front-ends where both precision and headroom are non-negotiable.

FAQ
What is the operating temperature range for the TLE2071IDG4?
The TLE2071IDG4 is rated for −40°C to +85°C free-air operating temperature, matching the 'I' suffix designation in its part number. This range is validated per TI's characterization across all key parameters including offset voltage, bias current, and common-mode input range - ensuring reliable performance in industrial control cabinets and outdoor metering enclosures without derating.
Does the TLE2071IDG4 require external compensation for unity-gain stability?
No, the TLE2071IDG4 is internally compensated for unity-gain stability and maintains ≥56° phase margin with 25 pF capacitive load at ±15 V supplies. External compensation is unnecessary for standard inverting/non-inverting configurations with gains ≥1 - simplifying layout and reducing bill-of-materials count in high-speed analog signal paths.
Can the TLE2071IDG4 drive a 600 Ω load effectively?
Yes, the TLE2071IDG4 delivers ±20 mA continuous output current and maintains >80 dB large-signal voltage gain into 600 Ω loads at ±15 V supplies. Its output swing reaches ±13.5 V at 2 mA load - sufficient for driving legacy video lines, RF detector stages, or analog transmission standards without external buffers.
How does the offset null functionality work on the TLE2071IDG4?
The TLE2071IDG4 provides dedicated Offset Null pins (1 and 5) for connecting a 10 kΩ potentiometer between V− and V+, with wiper to Pin 1. Adjusting this potentiometer nulls input offset voltage to ≤100 µV - critical for DC-coupled integrators, precision current sources, and zero-balance bridge amplifiers where residual offset directly impacts system accuracy.
Is the TLE2071IDG4 pin-compatible with other TLE207x variants in SOIC-8?
Yes, all TLE207x and TLE207xA variants in the SOIC-8 (D) package - including TLE2071CDR, TLE2071ACDR, and TLE2071IDR - share identical pinout, footprint, and thermal pad configuration. This allows drop-in replacement across performance grades (C/I/A) without PCB revision, provided supply and temperature requirements align with the selected variant.
