Product details
Overview
TLE2071CD 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 AC drive power stages.
For engineers reviewing the TLE2071CD datasheet, TLE2071CD pinout, TLE2071CD application, or TLE2071CD equivalent, this page provides verified specifications, SOIC-8 package details, real-world use cases in high-speed data acquisition and portable instrumentation, and validated alternative options with documented functional trade-offs.
Technical Context
The TLE2071CD uses Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, supporting rail-to-rail differential input operation up to ±19 V supplies. Its wide bandwidth and low noise floor stem from optimized transconductance and output stage design, not composite or current-feedback topology.
It operates stably in unity-gain configuration with 56° phase margin (CL = 25 pF, RL = 2 kΩ), exhibits 98 dB CMRR at ±15 V supply, and maintains 100 MΩ common-mode input resistance - making it suitable for high-impedance sensor interfacing without external guarding.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10.6 MHz unity-gain bandwidth enables stable amplification of signals up to ~10 MHz without peaking. |
| Slew Rate | 32 V/μs supports clean reproduction of fast 10-V step signals within 0.4 μs settling to 1 mV. |
| Input Noise | 17 nV/√Hz at 1 kHz ensures minimal added noise in precision analog front-ends for DMMs and digitizers. |
| Supply Range | ±2.25 V to ±19 V allows direct interface with industrial ±15 V systems and battery-powered ±5 V designs. |
| Input Bias Current | ±15 pA typical enables high-impedance source coupling (e.g., piezoelectric sensors, pH electrodes) without significant offset drift. |
| Offset Voltage | 4 mV max (C-suffix, 0°C to 70°C) provides baseline DC accuracy for closed-loop gain ≥100 without trimming. |
| CM Input Range | Extends to within 1.9 V of negative rail and 1 V of positive rail at ±5 V supply - supports single-supply biasing with proper headroom. |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6 mm body, surface-mount, JEDEC MS-012AC compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to external potentiometer for manual input offset adjustment; unused in standard configurations. |
| 2 | Inverting Input (–) | Differential input node; high-impedance JFET gate with 100 MΩ common-mode resistance. |
| 3 | Non-inverting Input (+) | Differential input node; accepts common-mode voltages up to supply rails minus safety margin. |
| 4 | V– | Negative supply terminal; must be decoupled locally to minimize PSRR degradation above 10 kHz. |
| 5 | Offset Null (N2) | Second terminal of offset null potentiometer; tied to midpoint of 10-kΩ trimmer when used. |
| 6 | Output | Capable of ±65 mA short-circuit current; drives 600 Ω loads with <0.0032% THD+N at 1 kHz. |
| 7 | V+ | Positive supply terminal; supports up to +19 V with thermal derating above 70°C ambient. |
| 8 | No Connect | Internally unconnected; no routing or grounding required per TI datasheet Figure 5-1. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise JFET input | 17 nV/√Hz input voltage noise at 1 kHz enables sub-μV signal resolution in 10-Hz–10-kHz bandwidths. |
| Rail-compatible inputs | Accepts differential inputs spanning full supply range (±19 V), simplifying level-shifting in high-voltage sensor interfaces. |
| High open-loop gain | 106 dB large-signal voltage gain (RL = 10 kΩ) ensures <10 ppm gain error in precision non-inverting configurations. |
| Unity-gain stability | Stable with 25 pF capacitive load and 2 kΩ series resistor - eliminates need for external compensation in most buffer applications. |
| Wide supply tolerance | Operates from ±2.25 V to ±19 V, allowing reuse across ±5 V portable and ±15 V industrial platforms without redesign. |
Applications
| Oscilloscopes & Digitizers | Electricity Metering |

Equivalent & Alternatives
The following parts are listed as comparable options for similar op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL071CP | Higher input noise (18 nV/√Hz), lower slew rate (13 V/μs), same SOIC-8 package and pinout. | Less suitable for >1-MHz signal paths or ultra-low-noise DMM front-ends due to 3× higher noise density. | Select TL071CP only if cost sensitivity outweighs bandwidth/noise requirements and ±15 V supply suffices. |
| OPA2134PA | Lower noise (8 nV/√Hz), higher CMRR (120 dB), but limited to ±18 V max supply and higher quiescent current (4 mA vs. 2.48 mA). | Better for audio-grade precision but less robust in industrial ±19 V environments; requires tighter thermal management. | Choose OPA2134PA when noise performance is critical and supply stays ≤±18 V; verify layout for 4 mA per channel dissipation. |
Compared with TL071CP and OPA2134PA, the TLE2071CD uniquely balances 10.6 MHz bandwidth, ±19 V operation, and 17 nV/√Hz noise in a cost-effective SOIC-8 package - making it optimal for industrial test equipment where supply headroom and speed coexist with noise constraints.

FAQ
What is the maximum supply voltage for the TLE2071CD?
The TLE2071CD supports a total supply voltage range of ±2.25 V to ±19 V, meaning the absolute maximum voltage difference between V+ and V– is 38 V. This allows direct integration into ±15 V industrial systems with 4-V headroom for transients - a key advantage over standard ±15 V-rated op-amps. The TLE2071CD datasheet specifies this limit under Absolute Maximum Ratings Table 6.1.
Does the TLE2071CD require external compensation for unity-gain stability?
No, the TLE2071CD is unity-gain stable without external compensation components. Its internal compensation ensures 56° phase margin with a 25-pF capacitive load and 2-kΩ series resistor, as confirmed in Section 6.4 of the TLE2071CD datasheet. This eliminates the need for external capacitors in buffer or gain-of-one configurations, reducing BOM count and board space.
What is the input bias current specification for the TLE2071CD at 25°C?
The TLE2071CD has a typical input bias current of ±15 pA at 25°C, with a maximum of ±175 pA across the 0°C to 70°C operating range. This ultra-low value stems from its JFET-input architecture and enables accurate amplification of signals from high-impedance sources such as photodiodes, piezoelectric sensors, and pH electrodes without significant current-induced offset errors.
Can the TLE2071CD drive a 600-Ω load with low distortion?
Yes, the TLE2071CD delivers 0.0032% THD+N into a 10-kΩ load at 1 kHz and 3 VRMS, and maintains low distortion into 600 Ω due to its ±65 mA short-circuit output current capability and 106 dB open-loop gain. At G = 1 and 1 kHz, distortion remains below 0.01% into 600 Ω - verified in Section 6.4 of the TLE2071CD datasheet - making it suitable for precision line-driver applications.
Is the TLE2071CD pin-compatible with other SOIC-8 op-amps like the TL071?
Yes, the TLE2071CD uses the industry-standard SOIC-8 pinout (pin 1 = offset null N1, pin 2 = inverting input, pin 3 = non-inverting input, pin 4 = V–, pin 5 = offset null N2, pin 6 = output, pin 7 = V+, pin 8 = NC), matching TL071CP, OP07CP, and many other general-purpose op-amps. However, functional equivalence requires verification of bandwidth, noise, and supply range - the TLE2071CD offers superior slew rate and wider supply than TL071CP.
