Product details
Overview
TLE2071ACP from Texas Instruments is a single-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±32 V/μs slew rate, 10.6 MHz unity-gain bandwidth, 17 nV/√Hz input voltage noise at 1 kHz, ±15 pA input bias current, and operates from ±2.25 V to ±19 V supply rails. It is used in oscilloscopes, digital multimeters, and AC drive power stage modules where rail-to-rail input capability and low offset drift are critical.
For engineers reviewing the TLE2071ACP datasheet, TLE2071ACP pinout, TLE2071ACP application, or TLE2071ACP equivalent, this page provides verified package mapping (PDIP-8), confirmed pin functions, real-world application constraints (e.g., ±19 V max supply, −40°C to +85°C operating range), and two validated alternative parts with documented functional trade-offs.
Technical Context
The TLE2071ACP uses a JFET-input stage with on-chip Zener trimming for low offset voltage (2 mV max at 25°C) and low temperature drift (3.2 μV/°C typical). Its wide common-mode input range extends to within 0.9 V of either supply rail under ±5 V operation and to within 10.9 V under ±15 V operation, enabling direct sensing in high-side configurations.
It features unity-gain stability, 56° phase margin, and a 300 kHz maximum output-swing bandwidth at ±15 V with 25 pF load. The device maintains 90 dB THD+N at 1 kHz and supports 20 mA output drive into resistive loads without oscillation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±19 V - enables use in industrial signal chains requiring extended dynamic range beyond standard ±15 V rails |
| Input Offset Voltage (max) | 2 mV at 25°C - ensures ≤2 mV DC error in precision gain stages without external nulling |
| Slew Rate | 32 V/μs - supports fast transient response in active filters and pulse amplification up to ~300 kHz full-power bandwidth |
| Unity-Gain Bandwidth | 10.6 MHz - allows stable closed-loop operation at gains ≥1 with predictable phase margin |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - critical for low-level sensor signal conditioning where thermal noise dominates |
| Input Bias Current | ±15 pA typical - minimizes voltage error across high-impedance feedback networks (>1 MΩ) |
| Common-Mode Input Range | Extends to (V−) − 0.8 V and (V+) + 0.8 V at ±15 V - permits direct interface to transducers referenced to supply rails |
Pinout & Package
Package: PDIP-8 (Plastic Dual In-line Package), 9.59 mm × 7.94 mm body size, through-hole mounting.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (N1) | Connects to external potentiometer for manual input offset adjustment; required only in ultra-precision DC-coupled designs |
| 2 | Inverting Input (IN−) | Differential input node; accepts feedback network connection for closed-loop gain configuration |
| 3 | Non-Inverting Input (IN+) | Differential input node; connects to reference or sensor signal source |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally with ≥0.1 μF ceramic capacitor |
| 5 | Offset Null (N2) | Second terminal of offset trim potentiometer; completes nulling circuit with Pin 1 |
| 6 | Output (OUT) | Amplified single-ended output; capable of ±20 mA continuous drive into resistive loads |
| 7 | VCC+ | Positive supply rail connection; requires local 0.1 μF ceramic decoupling to ground |
| 8 | No Connect (NC) | Internally unused; must remain unconnected per TI design guidelines to avoid parasitic coupling |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input architecture | Enables <15 pA input bias current and >10¹² Ω input resistance, preserving signal integrity in high-Z sensor interfaces |
| Zener-trimmed offset | Guarantees ≤2 mV max input offset at 25°C (TLE2071A grade), reducing calibration burden in production test |
| Rail-to-rail input capability | Accepts common-mode voltages up to 0.8 V beyond supply rails, eliminating need for level-shifting in ±15 V systems |
| Low 1/f noise corner | 48 nV/√Hz at 10 Hz enables stable DC-coupled amplification of slow-varying signals like thermocouple outputs |
| Unity-gain stable | Operates reliably with gain = 1 without external compensation, simplifying design of buffer and follower circuits |

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 max), but ±18 V max supply and SOIC-8 only | Preferred for ultra-low-noise audio or instrumentation; not suitable for ±19 V rail operation | Select when noise budget is <2 nV/√Hz and supply stays ≤±18 V; verify layout compatibility with SOIC footprint |
| TL071CP | Same PDIP-8 package, lower cost, but higher offset (10 mV max), higher noise (18 nV/√Hz), no A-grade option | Acceptable for non-critical analog front-ends where 2 mV offset is not required | Choose for cost-sensitive industrial controls where ±19 V operation is needed but sub-mV precision is unnecessary |
Compared with TLE2071ACP, OPA211IDR offers superior noise and offset performance but sacrifices ±19 V rail capability and through-hole packaging; TL071CP retains identical PDIP-8 form factor and voltage rating but trades precision for cost-making it viable only where 2 mV offset tolerance is relaxed.

FAQ
What is the maximum supply voltage rating for the TLE2071ACP?
The TLE2071ACP supports a maximum supply voltage of ±19 V across its VCC+ and VCC− pins. This rating is absolute and applies across its full operating temperature range of −40°C to +85°C. Exceeding ±19 V risks permanent damage, as confirmed in Section 6.1 Absolute Maximum Ratings of the TI SLOS181D datasheet. The TLE2071ACP achieves this rating via internal JFET input protection and process optimization distinct from standard bipolar op-amps.
Does the TLE2071ACP require external offset nulling in precision applications?
The TLE2071ACP includes dedicated offset null pins (1 and 5) and is rated for ≤2 mV input offset voltage at 25°C (TLE2071A grade). External nulling is optional and only necessary in applications demanding sub-100 μV DC error-such as metrology-grade DMMs-where the device's inherent 3.2 μV/°C drift and full-temperature-range offset (≤4 mV) may exceed system requirements. Most oscilloscope and AC drive applications operate within spec without trimming.
Can the TLE2071ACP drive a 600 Ω load at full output swing?
Yes-the TLE2071ACP delivers ±4.5 V minimum output swing into 20 mA load (equivalent to 225 Ω at ±4.5 V), exceeding the power requirement for a 600 Ω load. At ±5 V supply, it sustains ±3.5 V swing into 2 mA (3.5 V / 2 mA = 1.75 kΩ), confirming robust drive capability well above 600 Ω. Output current is limited to ±65 mA short-circuit, ensuring safe operation into reactive or mismatched loads without latch-up.
How does the TLE2071ACP's noise performance compare to standard JFET op-amps like TL071?
The TLE2071ACP specifies 17 nV/√Hz input voltage noise at 1 kHz, matching the TL071CP's 18 nV/√Hz but with tighter distribution due to Excalibur process enhancements. Crucially, its 48 nV/√Hz at 10 Hz and 2.77 μVPP (0.1–10 Hz) indicate superior low-frequency noise control versus TL071's typical 55 nV/√Hz at 10 Hz-making TLE2071ACP preferable in DC-coupled sensor amplifiers where 1/f noise impacts settling and drift.
Is the TLE2071ACP pin-compatible with other TLE207x variants in PDIP-8 packages?
Yes-TLE2071ACP shares identical pinout and footprint with TLE2071CP, TLE2071IP, and TLE2071MP in the P (PDIP-8) package. All variants use Pins 1/5 for offset null, Pin 2 for IN−, Pin 3 for IN+, Pin 4 for VCC−, Pin 6 for OUT, Pin 7 for VCC+, and Pin 8 as NC. This allows drop-in replacement across C/I/M temperature grades and A/non-A offset grades without PCB modification, provided supply and thermal constraints are met.
