Product details
Overview
TLE2071AIP from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±300 µV typical input offset voltage, 17 nV/√Hz input voltage noise at 1 kHz, 10 MHz unity-gain bandwidth, ±19 V supply capability, and operates across −40°C to +85°C. It serves as a signal-conditioning front-end in electricity meters and oscilloscope analog acquisition stages.
For engineers reviewing the TLE2071AIP datasheet, TLE2071AIP pinout, TLE2071AIP application, or TLE2071AIP equivalent, key selection criteria include its rail-to-rail input operation, low bias current (±15 pA), wide common-mode range (−10.9 V to +15 V at ±15 V supplies), and compatibility with high-impedance sensor interfaces requiring minimal DC error and broadband fidelity.
Technical Context
The TLE2071AIP uses a JFET-input stage with on-chip Zener trimming for offset calibration, enabling stable DC precision without external nulling. Its architecture supports differential inputs up to the supply rails and maintains unity-gain stability with 56° phase margin at 2 kΩ load and 25 pF capacitance.
It achieves 32 V/µs slew rate and 0.4 µs settling time to 1 mV for a 10 V step under ±15 V supplies, making it suitable for fast transient response in data acquisition and active filter implementations where both speed and low noise are critical.
Key Specifications

|---|---|
| Input Offset Voltage | ±300 µV typ - enables accurate DC-coupled amplification with sub-millivolt error in precision measurement paths |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - preserves signal integrity in low-level sensor interfaces like shunt-based current sensing |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier 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 | Preferred for ultra-low-noise lab instrumentation; not drop-in due to different pinout and no offset-null pins | Select when ultimate noise performance outweighs need for offset trimming or PDIP packaging |
| TL071CP | Higher offset (±10 mV), higher noise (18 nV/√Hz), same PDIP-8 package and pinout, but no offset-null terminals | Cost-sensitive general-purpose use; lacks precision features needed for metrology-grade metering | Choose only for non-critical signal conditioning where offset drift and noise are acceptable |
Compared with OPA211IDR and TL071CP, the TLE2071AIP uniquely balances low-noise (17 nV/√Hz), trimmable offset (via Pins 1/5), ±19 V supply headroom, and through-hole PDIP-8 compatibility-making it optimal for industrial test equipment and energy meter designs requiring field-serviceability and long-term DC stability.

FAQ
What is the maximum supply voltage rating for the TLE2071AIP?
The TLE2071AIP supports a total supply voltage range of ±2.25 V to ±19 V, meaning the absolute maximum difference between V+ and V− is 38 V. This allows operation on standard ±15 V rails with 4 V headroom, supporting robust signal swing in industrial analog front-ends. Exceeding ±19 V violates Absolute Maximum Ratings and risks permanent damage.
Does the TLE2071AIP require external offset nulling in all applications?
The TLE2071AIP includes dedicated offset null pins (1 and 5) for manual trimming, but nulling is optional. With ±300 µV typical input offset voltage and ±2 mV maximum over temperature, many applications-including electricity meters and oscilloscope buffers-operate within specification without trimming. Use nulling only when sub-millivolt DC accuracy is mandatory across full temperature range.
Can the TLE2071AIP drive capacitive loads directly?
The TLE2071AIP is unity-gain stable but exhibits reduced phase margin with capacitive loads >100 pF. For loads exceeding 50 pF, TI recommends adding a series resistor (10–100 Ω) between the output and capacitance to isolate the pole. This preserves stability in active filter and cable-driving applications without degrading bandwidth beyond design intent.
How does the TLE2071AIP compare to the standard TLE2071IP in terms of precision?
The TLE2071AIP offers tighter DC specifications than the TLE2071IP: ±300 µV vs. ±400 µV typical input offset voltage, and ±2 mV vs. ±4 mV maximum over temperature. Both share identical noise (17 nV/√Hz), bandwidth (10.6 MHz), and slew rate (32 V/µs). The "A" grade is specified for higher-precision applications such as Class 0.2 electricity meters and calibrated test equipment.
Is the TLE2071AIP pin-compatible with other PDIP-8 op-amps like the TL071CP?
No-the TLE2071AIP has offset null pins (1 and 5) not present on the TL071CP, which uses Pins 1 and 5 for different functions (output compensation and NC). Direct substitution would cause incorrect biasing or instability. While both are PDIP-8, their pinouts differ; PCB layout must match the TLE2071AIP's specific terminal mapping to ensure proper operation.
