Product details
Overview
TLE2071CPG4 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 (TLE2071A variant), 17 nV/√Hz input voltage noise at 1 kHz, 10 MHz unity-gain bandwidth, ±19 V supply capability, and operates across 0°C to 70°C. It serves signal conditioning in oscilloscopes, electricity meters, and AC drive power stages.
For engineers reviewing the TLE2071CPG4 datasheet, TLE2071CPG4 pinout, TLE2071CPG4 application, or TLE2071CPG4 equivalent, this page provides verified specifications, package mapping to PDIP-8, functional context for high-precision analog front-ends, and validated alternative options with documented parameter trade-offs.
Technical Context
The TLE2071CPG4 uses Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, enabling rail-to-rail differential input operation up to ±19 V supplies. Its 32 V/µs slew rate and 10.6 MHz unity-gain bandwidth support fast settling in data acquisition and active filtering.
It achieves 85 dB common-mode rejection and 99 dB supply-voltage rejection at 25°C under ±5 V supply, with input bias current as low as ±15 pA - critical for high-impedance sensor interfaces and integrator circuits where leakage-induced drift 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 without external level-shifting. |
| Input Offset Voltage (Typ) | ±300 µV (TLE2071A grade) - enables sub-mV accuracy in precision gain stages and reference buffers. |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - ensures minimal added noise in low-level signal amplification (e.g., transducer outputs). |
| Unity-Gain Bandwidth | 10.6 MHz - allows stable operation in unity-gain configurations for high-fidelity buffering and active filters. |
| Slew Rate | 32 V/µs - supports ≤300 ns settling to 1 mV for 10 V steps, suitable for medium-speed data acquisition. |
| Input Bias Current | ±15 pA max at 25°C - preserves signal integrity in photodiode, piezoelectric, and high-Z source interfaces. |
| Common-Mode Input Range | Extends to within 1 V of rails (e.g., −10.9 V to +15 V at ±15 V supply) - simplifies design of single-supply compatible circuits using dual supplies. |
Pinout & Package
Package: PDIP-8 (Plastic Dual In-line Package), 9.59 mm × 7.94 mm, through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to external potentiometer for fine-tuning input offset voltage - required only in ultra-high-DC-accuracy applications. |
| 2 | Inverting Input (1IN–) | Differential input node; accepts feedback network connection for closed-loop gain configuration. |
| 3 | Non-Inverting Input (1IN+) | Differential input node; connects to signal source or reference in follower/buffer configurations. |
| 4 | VCC– | Negative supply rail connection - must be decoupled locally to minimize noise coupling into high-impedance inputs. |
| 5 | Offset Null (N2) | Second terminal of offset null potentiometer - used with Pin 1 to balance input stage mismatch. |
| 6 | Output (OUT) | Amplified output node - capable of ±20 mA continuous drive into resistive loads with <1.5 V headroom at ±15 V supply. |
| 7 | VCC+ | Positive supply rail connection - requires local 0.1 µF ceramic decoupling adjacent to pin for stability. |
| 8 | No Connect (NC) | Internally unused pin - left unconnected; no routing or grounding required. |
Key Features
| Feature | Design Value |
|---|---|
| Low input voltage noise | 17 nV/√Hz at 1 kHz enables clean amplification of microvolt-level signals from strain gauges or thermocouples. |
| JFET input stage | ±15 pA input bias current minimizes error in high-source-impedance circuits like charge amplifiers and pH probes. |
| Rail-to-rail differential input | Accepts inputs up to ±0.5 V beyond supply rails - eliminates need for input clamping diodes in overvoltage-prone systems. |
| Excalibur process with Zener trimming | Delivers ±300 µV typical VIO and 3.2 µV/°C drift - reduces calibration frequency in portable DMMs and field instruments. |
| Unity-gain stable | Operates reliably with gain = 1 without external compensation - simplifies design of non-inverting buffers and active filters. |

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 offset (±10 mV max), higher noise (18 nV/√Hz), same PDIP-8 package and pinout. | Lower DC precision; suitable for audio and general-purpose use but not metrology-grade measurements. | Select TL071CP only when cost sensitivity outweighs offset/noise requirements and ±10 mV error is acceptable. |
| OPA2134PA | Lower noise (8 nV/√Hz), lower bias current (±1 pA), SO-8 package - not pin-compatible with PDIP-8. | Superior performance in ultra-low-noise sensor interfaces, but requires PCB redesign due to different footprint and lead pitch. | Choose OPA2134PA when noise budget is <10 nV/√Hz and layout flexibility exists for SO-8 rework. |
Compared with TL071CP, TLE2071CPG4 offers 33× lower typical offset and tighter drift control; versus OPA2134PA, it trades 53% higher voltage noise for proven PDIP-8 compatibility and broader supply tolerance (±19 V vs. ±18 V), easing drop-in upgrades in legacy industrial designs.

FAQ
What is the maximum supply voltage rating for the TLE2071CPG4?
The TLE2071CPG4 supports a total supply voltage (VCC+ – VCC−) up to 38 V, with individual rails rated from ±2.25 V to ±19 V. This ±19 V capability enables direct interfacing with high-voltage industrial sensors and power stage monitors without external level-shifting circuitry, and is confirmed in Section 6.1 Absolute Maximum Ratings of the TI SLOS181D datasheet.
Does the TLE2071CPG4 require external offset nulling in standard applications?
The TLE2071CPG4 does not require external offset nulling for most applications: its typical input offset voltage is ±300 µV (TLE2071A grade), and maximum is 4 mV over 0°C–70°C. Pins 1 and 5 are provided for optional nulling via a 10 kΩ potentiometer only when sub-millivolt DC accuracy is mandatory - such as in precision weigh scales or calibration references.
Is the TLE2071CPG4 unity-gain stable, and what is its phase margin?
Yes, the TLE2071CPG4 is unity-gain stable with a measured phase margin of 56° at 25°C under ±5 V supply with 25 pF load and 2 kΩ load resistance. This stability is guaranteed across its full operating range and eliminates the need for external compensation networks in buffer, follower, or gain-of-one configurations per Section 6.4 and 6.6 of the datasheet.
What is the input bias current specification for the TLE2071CPG4 at 85°C?
At 85°C, the TLE2071CPG4 exhibits a maximum input bias current of 5 nA (full-range spec for TLE2071C grade), per Table 6.7 Electrical Characteristics. This remains significantly lower than bipolar-input op-amps and ensures minimal voltage error in high-impedance circuits like photodiode transimpedance amplifiers operating in warm environments.
Can the TLE2071CPG4 drive a 600 Ω load at ±15 V supply while maintaining linearity?
Yes - the TLE2071CPG4 delivers ±20 mA output current and maintains large-signal differential voltage amplification of ≥80 dB into 600 Ω loads at ±15 V supply (Section 6.5). Its output swing reaches ±13.5 V at 2 mA load, ensuring >90% of rail-to-rail utilization and <0.0032% THD+N at 1 kHz - sufficient for driving legacy video lines or RF test equipment inputs.
