Product details
Overview
TLE2072IDRG4 from Texas Instruments is a dual JFET-input operational amplifier optimized for high-voltage, low-noise, and high-speed precision signal conditioning. It delivers 10 MHz unity-gain bandwidth, 32 V/µs slew rate, ±19 V supply capability, 17 nV/√Hz input voltage noise at 1 kHz, and ±15 pA input bias current - enabling accurate amplification in oscilloscope front-ends and electricity meter sensor interfaces.
For engineers reviewing the TLE2072IDRG4 datasheet, TLE2072IDRG4 pinout, TLE2072IDRG4 application, or TLE2072IDRG4 equivalent, key selection criteria include rail-to-rail input operation, low offset drift (3.2 µV/°C), wide common-mode range (±10.8 V at ±15 V supplies), and SOIC-8 packaging compatibility with industrial temperature range (−40°C to +85°C).
Technical Context
The TLE2072IDRG4 employs Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, supporting stable closed-loop operation up to 10 MHz without external compensation. Its input stage operates with differential inputs extending to both supply rails, enabling direct interfacing with high-impedance sensors and transducers.
Designed for unity-gain stability, it maintains 56° phase margin with 2 kΩ load and 25 pF capacitive load, while delivering full-swing output capability (±14.5 V at ±15 V supplies, 20 mA load) and high open-loop gain (>95 dB at 10 kΩ load) across its −40°C to +85°C operating range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10.6 MHz unity-gain bandwidth enables accurate amplification of fast analog signals up to ~10 MHz without gain peaking. |
| Slew Rate | 32 V/µs supports clean reproduction of 2-V step signals within 0.4 µs to 1 mV accuracy - critical for data acquisition front-ends. |
| Input Noise | 17 nV/√Hz at 1 kHz ensures minimal added noise in precision sensor signal chains, such as shunt-based current sensing. |
| Supply Range | ±2.25 V to ±19 V allows operation from low-voltage portable systems to high-dynamic-range industrial power monitoring. |
| Input Bias Current | ±15 pA typical enables use with high-impedance sources (e.g., piezoelectric sensors, pH electrodes) without significant error. |
| Offset Voltage | 6 mV max at 25°C (I-grade) provides predictable DC accuracy in closed-loop configurations like active filters and instrumentation amps. |
| CMRR | 98 dB at ±15 V supplies rejects common-mode interference in noisy industrial environments, preserving signal integrity. |

Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input operation | Accepts common-mode voltages from (V–) – 0.8 V to (V+) + 0.5 V, simplifying level-shifting in multi-supply systems. |

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 |
|---|---|---|---|
| TL072CDR | Higher input noise (18 nV/√Hz), wider offset spread (10 mV max), no Zener trimming; lower cost. | Limited to less demanding audio and general-purpose analog circuits - not recommended for metrology-grade metering. | Select TL072CDR only when budget constraints outweigh need for low drift and guaranteed noise performance. |
| OPA2134PA | Lower noise (8 nV/√Hz), higher GBW (8 MHz), FET input but no rail-to-rail input; ±18 V max supply. | Better suited for audio and low-distortion applications; lacks rail-to-rail input needed for single-supply sensor interfaces. | Choose OPA2134PA where ultra-low THD+N (<0.00008%) and lower noise dominate over input voltage range requirements. |
Compared with TL072CDR and OPA2134PA, the TLE2072IDRG4 uniquely balances rail-to-rail input operation, 17 nV/√Hz noise, ±19 V supply, and Zener-trimmed offset - making it optimal for industrial measurement systems requiring both wide dynamic range and DC precision.

FAQ
What is the maximum supply voltage rating for the TLE2072IDRG4?
The TLE2072IDRG4 supports a total supply voltage (V+ to V−) up to 38 V, allowing operation from ±2.25 V to ±19 V. This enables use in high-dynamic-range applications such as power supply monitoring and motor current sensing where wide headroom is required. Absolute maximum ratings must not be exceeded during operation or transient conditions.
Does the TLE2072IDRG4 support rail-to-rail input operation?
Yes, the TLE2072IDRG4 supports rail-to-rail input operation: its common-mode input voltage range extends from (V−) − 0.8 V to (V+) + 0.5 V at ±15 V supplies. This allows direct interfacing with sensors and transducers whose output spans near the supply rails - a key advantage over standard bipolar-input op-amps in precision measurement systems.
What is the typical input voltage noise density of the TLE2072IDRG4 at 1 kHz?
The typical input voltage noise density of the TLE2072IDRG4 is 17 nV/√Hz at 1 kHz, as specified in the official Texas Instruments datasheet. This value is confirmed across multiple test conditions and is representative of its Excalibur JFET-input architecture - making it suitable for low-noise applications such as shunt-based current sensing and high-resolution data acquisition.
Is the TLE2072IDRG4 unity-gain stable?
Yes, the TLE2072IDRG4 is unity-gain stable and requires no external compensation. Its internal compensation ensures ≥56° phase margin under standard test conditions (10 mV input, 25 pF load, 2 kΩ load), enabling reliable use in voltage followers, active filters, and gain-of-1 signal buffers without risk of oscillation.
What does the 'I' and 'G4' suffix indicate in TLE2072IDRG4?
The 'I' suffix denotes the industrial temperature grade (−40°C to +85°C), while 'G4' indicates TI's green packaging standard (lead-free, RoHS-compliant, halogen-free). The 'R' signifies tape-and-reel packaging, and 'D' specifies the SOIC-8 package. Together, TLE2072IDRG4 identifies a lead-free, industrial-grade, tape-and-reel SOIC-8 dual op-amp meeting strict environmental and reliability requirements.
