Product details
Overview
TLE2072CDRG4 from Texas Instruments is a dual-channel JFET-input operational amplifier optimized for high-voltage, low-noise, and high-speed precision applications. It delivers ±19V supply rails, 10MHz unity-gain bandwidth, 32V/μs slew rate, 17nV/√Hz input voltage noise at 1kHz, and ±15pA input bias current - enabling accurate signal conditioning in oscilloscopes, electricity meters, and AC drive power stages.
For engineers reviewing the TLE2072CDRG4 datasheet, TLE2072CDRG4 pinout, TLE2072CDRG4 application, or TLE2072CDRG4 equivalent, this device supports rail-to-rail differential input operation, wide dynamic range signal acquisition, and stable unity-gain configurations - critical for high-fidelity analog front-ends in test equipment and industrial metering.
Technical Context
The TLE2072CDRG4 uses Excalibur JFET-input architecture with on-chip Zener trimming for low offset drift and high input impedance (>10¹² Ω). Its internal compensation ensures unity-gain stability while maintaining 56° phase margin with 2kΩ load and 25pF capacitive load.
It operates across 0°C to 70°C ambient temperature with ±2.25V to ±19V dual-supply capability, supporting common-mode input voltages extending to within 0.9V of either rail at ±5V supplies and to within 10.9V at ±15V supplies - ideal for high-voltage sensor interfacing and data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent amplifiers in single SOIC-8 package - enables compact dual-path signal conditioning without cross-talk. |
| Supply Voltage Range | ±2.25V to ±19V - supports wide dynamic range in high-voltage industrial sensing and power electronics monitoring. |
| Unity-Gain Bandwidth | 10.6MHz - allows stable amplification of signals up to ~10MHz without external compensation. |
| Slew Rate | 32V/μs - ensures faithful reproduction of fast transients in oscilloscope vertical amplifiers and pulse conditioning circuits. |
| Input Voltage Noise | 17nV/√Hz at 1kHz - minimizes added noise in precision DC-coupled measurement paths like digital multimeters. |
| Input Bias Current | ±15pA (typ) - preserves accuracy when driving high-impedance sources such as piezoelectric sensors or photodiode transimpedance nodes. |
| Offset Voltage Max | 6mV (over 0°C to 70°C) - enables sub-1% error in gain stages with ≤1000V/V closed-loop gain. |
Pinout & Package
Package: SOIC-8 (D), 4.9mm × 6mm body, tape-and-reel (R suffix), RoHS-compliant.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | High-impedance JFET node accepting differential signal reference; supports rail-to-rail common-mode swing. |
| 2 | Non-inverting input (Channel 1) | High-impedance JFET node for signal source connection; matched to Pin 1 for CMRR >85dB. |
| 3 | Output (Channel 1) | Capable of ±20mA continuous output into resistive loads; drives 600Ω directly with <0.0032% THD+N. |
| 4 | V– (Negative Supply) | Reference return for both channels; must be decoupled locally to minimize PSRR degradation. |
| 5 | Non-inverting input (Channel 2) | Independent high-Z input for second signal path; electrically isolated from Channel 1 except shared supply pins. |
| 6 | Inverting input (Channel 2) | Matched to Pin 5; enables dual instrumentation amplifier configurations with common-mode rejection. |
| 7 | Output (Channel 2) | Identical performance to Pin 3; supports dual-channel simultaneous sampling in data acquisition front-ends. |
| 8 | V+ (Positive Supply) | Power rail for both amplifiers; requires low-ESR ceramic bypass (0.1μF + 4.7μF) near pin for stability. |
Key Features
| Feature | Design Value |
|---|---|
| Low input voltage noise | 17nV/√Hz at 1kHz enables high-resolution DC-coupled measurements in electricity meters and DMMs without added noise floor. |
| Rail-to-rail differential input | Accepts inputs up to V– – 0.9V and V+ + 0.9V at ±5V supplies - simplifies level-shifting in high-side current sensing. |
| Unity-gain stable | No external compensation required for G = 1 configurations - reduces BOM count and layout area in buffer applications. |
| High slew rate | 32V/μs supports full-scale step response in <0.4μs to 1mV accuracy - essential for oscilloscope vertical deflection amplifiers. |
| Wide supply range | Operates from ±2.25V to ±19V - accommodates legacy ±15V systems and modern ±5V/±12V industrial controllers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDR | Lower slew rate (13V/μs), higher input noise (18nV/√Hz), no Zener-trimmed offset (max 10mV). | Less suitable for >1MHz signal acquisition; acceptable for audio and general-purpose buffering. | Choose TL072CDR only if cost sensitivity outweighs speed/noise requirements and offset budget allows ≥10mV. |
| OPA2134PA | Lower noise (8nV/√Hz), higher CMRR (100dB), but narrower supply range (±4.5V to ±18V) and no guaranteed operation at ±19V. | Better for ultra-low-noise audio; marginal for ±19V industrial rails where TLE2072CDRG4 is rated. | Select OPA2134PA when noise dominates design priority and supply stays ≤±18V; retain TLE2072CDRG4 for full ±19V compliance. |
Compared with TL072CDR and OPA2134PA, the TLE2072CDRG4 uniquely balances ±19V operation, 10.6MHz bandwidth, and 17nV/√Hz noise - making it the only option among the three qualified for high-voltage, high-speed precision roles in oscilloscopes and AC drive modules.

FAQ
What is the maximum supply voltage rating for the TLE2072CDRG4?
The TLE2072CDRG4 supports dual-supply operation from ±2.25V up to ±19V, with absolute maximum ratings of ±38V across V+ and V–. This allows direct integration into legacy ±15V systems and newer high-dynamic-range designs requiring extended headroom, such as oscilloscope vertical amplifiers and high-voltage sensor interfaces. Operation at ±19V is fully characterized and supported across its 0°C to 70°C temperature range.
Does the TLE2072CDRG4 require external compensation for unity-gain stability?
No, the TLE2072CDRG4 is internally compensated and unity-gain stable. It achieves 56° phase margin with a 2kΩ load and 25pF capacitive load, eliminating the need for external compensation components. This simplifies PCB layout and reduces bill-of-materials cost in buffer, follower, and gain-of-one configurations - a key advantage over decompensated amplifiers like the OPA627.
What is the input bias current specification for the TLE2072CDRG4 at 25°C?
The TLE2072CDRG4 exhibits a typical input bias current of ±15pA at 25°C, with a maximum of ±175pA over the full 0°C to 70°C operating range. This ultra-low bias current stems from its JFET-input architecture and enables accurate amplification of signals from high-impedance sources such as photodiodes, piezoelectric sensors, and high-value resistor dividers without significant input loading error.
Can the TLE2072CDRG4 drive a 600Ω load with low distortion?
Yes, the TLE2072CDRG4 delivers 0.0032% THD+N into a 10kΩ load at 1kHz and 3VRMS, and maintains low distortion into 600Ω loads due to its ±65mA short-circuit output current capability and 32V/μs slew rate. Its output swing reaches ±4.5V at ±20mA into 600Ω, supporting professional audio line-driving and test equipment signal generation without clipping or harmonic degradation.
Is the TLE2072CDRG4 pin-compatible with other devices in the TLE207x family?
Yes, the TLE2072CDRG4 shares identical SOIC-8 pinout with all TLE2072 variants including TLE2072ACDRG4, TLE2072IDRG4, and TLE2072AIDRG4. Pin functions (e.g., Pin 1 = IN– Ch1, Pin 8 = V+) are consistent across C-, I-, and M-suffix versions, enabling drop-in replacement for different temperature or offset specifications without PCB redesign.
