Product details
Overview
TLE2072ID from Texas Instruments is a dual JFET-input operational amplifier optimized for high-voltage, low-noise, and high-speed precision applications. It delivers ±19V supply operation, 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 flight control units.
For engineers reviewing the TLE2072ID datasheet, TLE2072ID pinout, TLE2072ID application, or TLE2072ID equivalent, this page provides verified specifications, SOIC-8 package details, functional alternatives, and design-critical performance context for high-fidelity analog front-end implementation.
Technical Context
The TLE2072ID uses JFET-input transistors with on-chip Zener trimming to achieve low offset voltage (max 6mV at 25°C) and ultra-low input bias current. Its rail-to-rail input stage supports common-mode voltages extending to within 0.8V of either supply rail under ±15V operation.
It features unity-gain stability, 56° phase margin, and maintains 300kHz full-power bandwidth at ±15V with 20mA output drive - making it suitable for wide-dynamic-range data acquisition and precision instrumentation where DC accuracy and AC fidelity are co-required.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25V to ±19V - enables operation in high-voltage industrial and test equipment without external level-shifting. |
| Input Offset Voltage (max) | 6mV at 25°C - ensures ≤6mV DC error in closed-loop gain ≥10 configurations without nulling circuitry. |
| Unity-Gain Bandwidth | 10.6MHz - supports stable amplification of signals up to ~10MHz with minimal phase lag. |
| Slew Rate | 32V/μs - allows faithful reproduction of fast 10V-step transitions in <0.4μs (to 1mV). |
| Input Voltage Noise | 17nV/√Hz at 1kHz - critical for preserving SNR in low-level sensor signal chains (e.g., strain gauge, thermocouple). |
| Input Bias Current | ±15pA typical - minimizes voltage error across high-impedance feedback networks (>10MΩ). |
| Common-Mode Input Range | −10.8V to +15V at ±15V supply - accepts inputs within 0.8V of rails, simplifying single-supply interface design. |
Pinout & Package
Package: SOIC-8 (D package), 4.9mm × 6mm body, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance differential input node; connects to feedback network for inverting configuration. |
| 2 | Non-Inverting Input (Channel 1) | High-Z input for reference or sensor signal; supports rail-to-rail common-mode range. |
| 3 | Output (Channel 1) | Capable of ±20mA continuous drive into 2kΩ load; specified for ±15V supply swing to ±14.5V. |
| 4 | VCC– | Negative supply rail connection; must be decoupled locally with 0.1μF ceramic capacitor. |
| 5 | Non-Inverting Input (Channel 2) | Independent second channel input; electrically isolated from Channel 1 except shared supply pins. |
| 6 | Inverting Input (Channel 2) | Second channel inverting input; identical electrical characteristics to Pin 1. |
| 7 | Output (Channel 2) | Second independent output; matches Channel 1 performance including slew rate and noise floor. |
| 8 | VCC+ | Positive supply rail connection; requires local 0.1μF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise JFET input stage | 17nV/√Hz input voltage noise at 1kHz enables high-resolution measurement in DMMs and digitizers. |
| Rail-to-rail input capability | Accepts common-mode signals within 0.8V of ±15V rails - eliminates need for input attenuators or level shifters. |
| High slew rate (32V/μs) | Supports accurate amplification of fast transient signals (e.g., pulse-width modulated motor control feedback). |
| Zener-trimmed offset voltage | Guarantees ≤6mV max VIO over −40°C to +85°C - reduces calibration burden in portable instrumentation. |
| Wide supply range (±2.25V to ±19V) | Operates directly from legacy ±15V industrial supplies or extended ±18V systems without regulation. |

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 offset (10mV max), lower slew rate (13V/μs), 16nV/√Hz noise - no Zener trimming. | Lower-cost general-purpose use; not rated for precision metrology or high-speed settling. | Choose TL072CDR only when cost sensitivity outweighs need for <6mV offset or >30V/μs slew rate. |
| OPA2134PA | Lower noise (8nV/√Hz), higher CMRR (100dB), but narrower supply (±18V max) and higher quiescent current (4mA/ch). | Better suited for audio-grade or ultra-low-distortion applications; less optimal for battery-powered portable meters. | Select OPA2134PA when noise performance is primary and supply headroom permits ±18V operation. |
Compared with TL072CDR and OPA2134PA, the TLE2072ID uniquely balances 6mV max offset, 32V/μs slew rate, and 17nV/√Hz noise within a −40°C to +85°C industrial temperature grade and ±19V supply capability - making it optimal for high-reliability, wide-dynamic-range instrumentation where all three parameters are simultaneously constrained.

FAQ
What is the maximum operating supply voltage for TLE2072ID?
The TLE2072ID supports a total supply voltage range of ±2.25V to ±19V, meaning the absolute maximum difference between VCC+ and VCC– is 38V. This allows direct use in legacy ±15V systems and extended ±18V industrial rails without external regulators - a key advantage over standard ±15V-rated op-amps.
Does TLE2072ID support rail-to-rail input operation?
Yes, the TLE2072ID accepts common-mode input voltages within 0.8V of either supply rail when operated at ±15V - i.e., from −10.8V to +15V. This rail-to-rail input capability eliminates the need for level-shifting circuitry in many sensor interface applications and improves dynamic range utilization.
What is the guaranteed input offset voltage specification for TLE2072ID over temperature?
The TLE2072ID has a maximum input offset voltage of 6mV at 25°C and 7.6mV over its full operating range of −40°C to +85°C. This specification is guaranteed per TI's SLOS181D datasheet Section 6.7, ensuring predictable DC error in precision gain stages without trimming.
Can TLE2072ID drive a 600Ω load at ±15V supply?
Yes, the TLE2072ID delivers ±20mA output current per channel, enabling direct driving of 600Ω loads at ±15V supply while maintaining full output swing (±14.5V). Its open-loop output impedance is 80Ω at 1MHz, ensuring stable closed-loop behavior into reactive or capacitive loads when properly compensated.
How does the noise performance of TLE2072ID compare to standard bipolar-input op-amps?
The TLE2072ID's 17nV/√Hz input voltage noise at 1kHz is significantly lower than typical bipolar-input op-amps (e.g., LM358: ~40nV/√Hz), due to its JFET input architecture. This makes it superior for low-level signal amplification where voltage noise dominates - such as piezoelectric sensors or high-impedance photodiode interfaces - while retaining low input bias current.
