Product details
Overview
TLE2071ACPG4 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 gain-bandwidth product, ±19 V supply rails, and 32 V/µs slew rate - enabling accurate signal conditioning in oscilloscopes, electricity meters, and flight control units.
For engineers reviewing the TLE2071ACPG4 datasheet, TLE2071ACPG4 pinout, TLE2071ACPG4 application, or TLE2071ACPG4 equivalent, this page provides verified specifications, package mapping to PDIP-8, functional context for rail-to-rail input operation and unity-gain stability, and validated alternative options for design continuity.
Technical Context
The TLE2071ACPG4 uses Excalibur JFET-input architecture with on-chip Zener trimming for low offset drift, supporting differential inputs up to the supply rails. Its wide bandwidth (10 MHz GBW) and high slew rate (32 V/µs) enable fast settling in data acquisition stages without phase margin degradation.
It operates across ±2.25 V to ±19 V supplies and maintains low bias current (±15 pA typ) and high input impedance (6 TΩ differential), making it suitable for high-impedance sensor interfaces and precision integrators where leakage and noise must be minimized.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±19 V - supports wide dynamic signal range in industrial and test equipment power domains. |
| Input Offset Voltage (Typ) | ±300 µV - enables sub-millivolt DC accuracy in precision instrumentation front-ends. |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - critical for low-noise amplification of weak analog signals (e.g., sensor outputs). |
| Gain-Bandwidth Product | 10 MHz - ensures stable unity-gain operation and sufficient bandwidth for 1–2 MHz signal paths. |
| Slew Rate | 32 V/µs - allows clean amplification of fast transients (e.g., pulse edges in DMM sampling circuits). |
| Input Bias Current (Typ) | ±15 pA - preserves signal integrity in high-impedance photodiode or piezoelectric sensor interfaces. |
| Common-Mode Input Range | Extends to within 1.9 V of rails (±15 V supply) - supports rail-to-rail input operation in single-supply derived systems. |
Pinout & Package
Package: PDIP-8 (Plastic Dual Inline Package, 9.59 mm × 7.94 mm), lead finish Sn/Pb, through-hole mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to external potentiometer for fine-tuning input offset voltage in ultra-precision applications. |
| 2 | Inverting Input (IN−) | Differential input node; accepts feedback network for closed-loop gain configuration. |
| 3 | Non-Inverting Input (IN+) | Differential input node; used for reference or signal injection in follower/buffer configurations. |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally for noise immunity. |
| 5 | Offset Null (N2) | Second terminal of offset null potentiometer; completes trimming circuit with Pin 1. |
| 6 | Output (OUT) | Amplified output signal; capable of ±14.5 V swing into 20 mA load at ±15 V supplies. |
| 7 | VCC+ | Positive supply rail connection; requires local 0.1 µF ceramic decoupling capacitor. |
| 8 | No Connect (NC) | Internally unused; must remain unconnected per TI specification to avoid parametric shift. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise JFET input stage | 17 nV/√Hz at 1 kHz enables high-fidelity amplification in sensitive measurement chains (e.g., DMM input buffers). |
| Zener-trimmed input offset | ±300 µV typical offset with <2 µV/°C drift supports stable DC-coupled designs over temperature. |
| Rail-to-rail input capability | Accepts common-mode voltages within 1.9 V of either supply rail - simplifies level-shifting in multi-supply systems. |
| Unity-gain stable architecture | Guarantees stability without external compensation in buffer, gain-of-1, or inverting amplifier configurations. |
| High slew rate + wide bandwidth | 32 V/µs slew rate and 10 MHz GBW allow accurate reproduction of fast pulses and AC waveforms up to ~1 MHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1 nV/√Hz), lower offset (±25 µV), but only ±18 V max supply; SOIC-8 only. | Better for ultra-low-noise audio or medical instrumentation; not drop-in due to different pinout and no offset-null pins. | Select when noise budget is <2 nV/√Hz and PCB layout allows SOIC-8; avoid if offset trimming or PDIP-8 footprint required. |
| TL071CP | Higher noise (18 nV/√Hz), higher offset (±3 mV), same PDIP-8 package and pinout; no offset-null terminals. | Cost-sensitive general-purpose replacement where ±3 mV offset and no trimming are acceptable. | Use for legacy board refreshes needing identical footprint and through-hole mounting, but expect reduced DC accuracy. |
Compared with OPA211IDR and TL071CP, the TLE2071ACPG4 uniquely balances low noise (17 nV/√Hz), trimmable offset (via Pins 1 & 5), and PDIP-8 compatibility - making it optimal for repair, calibration-critical, or high-voltage industrial instrumentation where layout change is constrained.

FAQ
What is the maximum supply voltage for the TLE2071ACPG4?
The TLE2071ACPG4 supports a total supply voltage range of ±2.25 V to ±19 V, meaning the maximum differential supply is 38 V. This allows operation in high-dynamic-range systems such as industrial power analyzers and high-voltage oscilloscope front-ends where ±15 V rails are standard. Absolute maximum ratings must not be exceeded to prevent permanent damage.
Does the TLE2071ACPG4 have offset null capability?
Yes, the TLE2071ACPG4 includes dedicated offset null terminals (Pins 1 and 5) that accept an external 10 kΩ potentiometer to adjust input offset voltage to near-zero. This feature is essential for applications like precision DMMs and calibration equipment where sub-100 µV residual offset is required after system-level trimming.
Is the TLE2071ACPG4 unity-gain stable?
Yes, the TLE2071ACPG4 is explicitly unity-gain stable, with a phase margin of 56° at unity gain (measured with CL = 25 pF, RL = 2 kΩ). This eliminates the need for external compensation in buffer, follower, or gain-of-1 configurations - simplifying design in oscilloscope vertical amplifiers and active filters.
What is the input bias current specification for the TLE2071ACPG4?
The TLE2071ACPG4 has a typical input bias current of ±15 pA at 25°C, enabled by its JFET-input architecture. This ultra-low value minimizes voltage errors in high-impedance sensor interfaces (e.g., piezoelectric accelerometers or pH electrodes), preserving signal fidelity without requiring guard traces or active guarding.
Which package type does the TLE2071ACPG4 use?
The TLE2071ACPG4 uses an 8-pin PDIP (Plastic Dual Inline Package) with dimensions 9.59 mm × 7.94 mm. The "G4" suffix denotes TI's RoHS-compliant Sn/Pb lead finish variant, fully compatible with legacy through-hole assembly processes and socket-based test fixtures used in calibration labs and repair centers.
