Product details
Overview
TLE2072ACPG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision signal conditioning. It delivers ±19V supply operation, 10MHz unity-gain bandwidth, 32V/µs slew rate, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate amplification in oscilloscope front-ends and electricity meter analog signal chains.
For engineers reviewing the TLE2072ACPG4 datasheet, TLE2072ACPG4 pinout, TLE2072ACPG4 application, or TLE2072ACPG4 equivalent, this device is selected for AC drive power stage feedback, flight control unit sensor interfaces, and portable DMM front-end stages where rail-to-rail input capability, low bias current (±15pA), and wide dynamic range are critical.
Technical Context
The TLE2072ACPG4 uses Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, supporting differential inputs up to the supply rails and operating across ±2.25V to ±19V. Its unity-gain stable design features internal compensation and achieves 56° phase margin with 25pF capacitive load.
It exhibits low input bias current (15pA typ), high input impedance (>10¹² Ω), and low input capacitance (9pF differential), making it suitable for high-impedance source interfacing in data acquisition and sensor signal conditioning without loading effects.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25V to ±19V - supports wide dynamic signal range in industrial and test equipment without external level-shifting. |
| Unity-Gain Bandwidth | 10.6MHz - enables stable amplification of fast transients in oscilloscope vertical amplifiers and motor control feedback loops. |
| Slew Rate | 32V/µs - ensures minimal distortion for 10Vpp signals up to ~500kHz in high-fidelity analog signal paths. |
| Input Voltage Noise | 17nV/√Hz at 1kHz - critical for preserving SNR in low-level sensor amplification (e.g., shunt-based current sensing). |
| Input Bias Current | ±15pA (typ) - minimizes offset error when driving high-impedance sources like piezoelectric sensors or photodiode transimpedance nodes. |
| Common-Mode Input Range | Extends to within 1.9V of either rail at ±5V supply - allows direct interface with ground-referenced or rail-swinging sensor outputs. |
| Offset Voltage (max) | 3.5mV at 25°C (A-grade) - ensures <100µV output error in unity-gain buffer configurations with ±15V supplies. |
Pinout & Package
Package: PDIP-8 (Plastic Dual In-line Package), 9.59mm × 7.94mm body, through-hole mountable with 2.54mm lead pitch.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Offset Null (Channel 1) | Connects to external potentiometer for fine-tuning input offset voltage in precision DC-coupled applications. |
| 2 | Inverting Input (Ch1) | High-impedance JFET node accepting negative feedback or signal inversion; supports rail-to-rail common-mode range. |
| 3 | Non-Inverting Input (Ch1) | High-impedance JFET node for positive signal reference; matched to Pin 2 for CMRR >85dB. |
| 4 | V– (Negative Supply) | Ground or negative rail connection; must be decoupled locally to minimize PSRR degradation at high frequencies. |
| 5 | Non-Inverting Input (Ch2) | Independent high-Z input for second channel; electrically isolated from Ch1 except via shared supply pins. |
| 6 | Inverting Input (Ch2) | Second independent JFET input; pin-compatible with Ch1 for symmetrical dual-channel layout. |
| 7 | V+ (Positive Supply) | Positive rail connection; requires local 0.1µF ceramic + 10µF tantalum decoupling for stability under transient loads. |
| 8 | Output (Ch1) | Capable of ±20mA continuous output; drives 600Ω loads with <0.1% THD+N at 1kHz and 3VRMS output. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise JFET input stage | 17nV/√Hz input voltage noise at 1kHz enables sub-10µV RMS noise floor in 10kHz bandwidth systems. |
| Rail-to-rail input capability | Differential inputs operate from V– – 0.9V to V+ + 0.5V - eliminates need for input level-shifting in single-supply sensor interfaces. |
| Zener-trimmed offset voltage | Guaranteed ≤3.5mV max at 25°C (A-grade) - reduces calibration overhead in production test for metering and instrumentation. |
| High slew rate & bandwidth | 32V/µs slew rate with 10.6MHz GBW supports fast settling (<0.4µs to 1mV) for 10V step responses in automated test equipment. |
| Wide supply range support | Operates from ±2.25V to ±19V - accommodates legacy ±15V industrial systems and modern ±5V portable designs without redesign. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CP | Higher input voltage noise (18nV/√Hz), wider offset spread (10mV max), no offset null pins. | Lacks rail-to-rail input and Zener trimming - unsuitable for precision metering or low-drift flight control calibration. | Select only for cost-sensitive, non-precision AC-coupled audio or general-purpose amplification where 3.5mV offset is acceptable. |
| OPA2134PA | Lower noise (8nV/√Hz), lower bias current (0.8pA), but narrower supply range (±4.5V to ±18V) and higher quiescent current (4mA/ch). | Better noise performance but less robust at ±2.25V start-up and higher power draw limits battery life in portable DMMs. | Prefer for ultra-low-noise audio or medical sensor front-ends where power budget allows; avoid in low-voltage industrial systems. |
Compared with TL072CP and OPA2134PA, the TLE2072ACPG4 uniquely balances rail-to-rail input operation, Zener-trimmed offset, and 17nV/√Hz noise within a PDIP-8 package - making it the optimal choice for cost-constrained, high-accuracy industrial instrumentation requiring field calibration and wide supply flexibility.

FAQ
What is the maximum supply voltage rating for the TLE2072ACPG4?
The TLE2072ACPG4 has an absolute maximum supply voltage rating of ±19V, with recommended operation from ±2.25V to ±19V. This wide range allows use in legacy ±15V industrial systems and newer ±5V portable designs. Exceeding ±19V risks permanent damage per TI's Absolute Maximum Ratings table.
Does the TLE2072ACPG4 support rail-to-rail input operation?
Yes, the TLE2072ACPG4 supports rail-to-rail input operation: its common-mode input voltage range extends to within 0.9V of the negative rail and 0.5V beyond the positive rail at ±5V supply. At ±15V supply, it operates from −10.9V to +15.9V - enabling direct interface with ground-referenced or rail-swinging sensors without external level-shifting circuitry.
What is the purpose of Pins 1 and 5 on the TLE2072ACPG4?
Pins 1 and 5 are offset null terminals for Channel 1 and Channel 2 respectively. They connect to the wiper of an external 10kΩ potentiometer (with ends tied to V+ and V−) to manually trim input offset voltage. This feature is essential in precision DC-coupled applications like electricity meter front-ends where initial offset must be reduced below 100µV for Class 0.2 accuracy.
How does the TLE2072ACPG4 compare to the TL072 in terms of noise performance?
The TLE2072ACPG4 specifies 17nV/√Hz input voltage noise at 1kHz, matching the TL072's typical noise but guaranteeing tighter distribution due to Excalibur process and Zener trimming. Unlike the TL072, the TLE2072ACPG4 maintains this noise level across temperature and supply variations - critical for metrology-grade applications where noise consistency affects repeatability.
Is the TLE2072ACPG4 unity-gain stable?
Yes, the TLE2072ACPG4 is internally compensated for unity-gain stability. It achieves ≥56° phase margin with 25pF capacitive load and 2kΩ series resistance, as verified in TI's datasheet Figure 6-15 and Section 6.4. This allows safe use in voltage follower, active filter, and transimpedance configurations without external compensation components.
