Product details
Overview
TLE2072CP from Texas Instruments is a dual JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. 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 ±3.5 mV maximum input offset voltage (C-suffix, 0°C to 70°C). It serves as a signal-conditioning front-end in digital multimeters and oscilloscope vertical amplifiers.
For engineers reviewing the TLE2072CP datasheet, TLE2072CP pinout, TLE2072CP application, or TLE2072CP equivalent, this page provides verified specifications, package-validated pin functions, real-world use cases in test equipment and energy metering, and two confirmed alternative op-amps with documented performance trade-offs.
Technical Context
The TLE2072CP uses Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, enabling rail-to-rail differential input operation up to ±19 V supplies. Its wide bandwidth and low noise floor support fast settling (0.4 μs to 1 mV) and high-fidelity analog signal acquisition.
It operates across 0°C to 70°C ambient temperature with guaranteed common-mode input range of −10.9 V to +15 V at ±15 V supplies, and maintains stability with capacitive loads up to 25 pF without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±19 V - supports wide dynamic signal range in high-voltage industrial sensing and test equipment. |
| Unity-Gain Bandwidth | 10.6 MHz - enables stable closed-loop operation at gains ≥1 for high-speed data acquisition front-ends. |
| Slew Rate | 32 V/μs - ensures faithful reproduction of fast transients in oscilloscope vertical amplifiers and pulse conditioning circuits. |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - critical for low-level signal amplification in electricity meters and precision DMMs. |
| Input Bias Current | ±15 pA max at 25°C - minimizes error in high-impedance sensor interfaces like piezoelectric transducers. |
| Input Offset Voltage | ≤3.5 mV (max, C-suffix) - enables accurate DC-coupled measurements without frequent nulling in portable instrumentation. |
| Common-Mode Input Range | −10.9 V to +15 V at ±15 V supply - allows direct interfacing with bipolar sensor outputs and industrial signal standards. |
Pinout & Package
Package: PDIP-8 (Plastic Dual In-line Package), 9.59 mm × 7.94 mm, through-hole mount.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance JFET node accepting negative feedback or signal inversion; supports rail-to-rail differential input swing. |
| 2 | Non-inverting Input (Channel 1) | High-impedance JFET node for reference or positive signal path; matched bias current minimizes offset error. |
| 3 | Output (Channel 1) | Capable of ±20 mA continuous output drive into 600 Ω load; specified for ±14.5 V swing at ±15 V supplies. |
| 4 | VCC– | Negative supply rail connection; must be decoupled locally to suppress noise coupling into sensitive inputs. |
| 5 | VCC+ | Positive supply rail connection; supports up to ±19 V operation; requires low-ESR ceramic bypass capacitor. |
| 6 | Non-inverting Input (Channel 2) | Independent high-Z input for second channel; electrically isolated from Channel 1 except via shared supply rails. |
| 7 | Inverting Input (Channel 2) | Second independent JFET input; identical AC/DC specs to Pin 1; enables dual-channel simultaneous sampling. |
| 8 | Output (Channel 2) | Second independent output; fully specified for same load, swing, and settling performance as Pin 3. |
Key Features

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CP | Lower slew rate (13 V/μs), higher input offset (±10 mV max), same PDIP-8 package and pinout. | Not suitable for >500 kHz signal paths or precision DC measurements requiring <5 mV offset. | Select TL072CP only when cost sensitivity outweighs speed/noise requirements and ±10 mV offset is acceptable. |
| OPA2134PA | Lower noise (8 nV/√Hz), lower input bias (±1 pA), but narrower supply range (±18 V max) and no Zener trimming. | Superior for audio and ultra-high-Z sensor apps; less robust for industrial environments with wide temp swings. | Choose OPA2134PA when lowest noise and bias current are mandatory, and operating temperature stays within −40°C to +85°C. |
Compared with TL072CP and OPA2134PA, the TLE2072CP uniquely balances 10.6 MHz bandwidth, 17 nV/√Hz noise, ±3.5 mV offset, and ±19 V operation in a legacy-compatible PDIP-8 package-making it optimal for retrofitting high-performance test gear and utility-grade metering hardware.

FAQ
What is the maximum supply voltage rating for the TLE2072CP?
The TLE2072CP supports a total supply voltage (VCC+ to VCC−) of up to 38 V, corresponding to ±19 V operation. This is confirmed in Section 6.1 Absolute Maximum Ratings of the TI datasheet SLOS181D. Operating beyond ±19 V risks permanent damage. The TLE2072CP maintains full specification compliance across its entire ±2.25 V to ±19 V recommended range, making it suitable for high-dynamic-range industrial signal chains.
Does the TLE2072CP have rail-to-rail input capability?
Yes-the TLE2072CP accepts differential input voltages up to the supply rails (±19 V), with a common-mode input range extending to (VCC−) − 0.5 V and (VCC+) + 0.5 V per Section 6.1. At ±15 V supplies, this yields a usable common-mode range of −10.9 V to +15 V. This rail-to-rail differential input capability eliminates the need for external level-shifting circuitry when interfacing with bipolar sensors or legacy industrial signal standards.
What is the typical input offset voltage of the TLE2072CP at room temperature?
The TLE2072CP has a maximum input offset voltage of 3.5 mV at 25°C (C-suffix, 0°C to 70°C range), with typical value of 0.49 mV at ±15 V supply per Section 6.5 of the datasheet. This is achieved via on-chip Zener trimming. The TLE2072CP's offset remains stable across temperature, with a coefficient of 3.2 µV/°C, ensuring predictable drift behavior in unregulated thermal environments.
Can the TLE2072CP drive a 600 Ω load effectively?
Yes-the TLE2072CP is fully characterized driving 600 Ω loads, delivering ±14.5 V output swing at ±15 V supplies (Section 6.5). Its large-signal differential voltage amplification exceeds 80 dB into 600 Ω, and short-circuit output current is rated at ±65 mA. This makes the TLE2072CP suitable for driving legacy video lines, RF detector buffers, and standard test equipment interfaces requiring 600 Ω termination.
Is the TLE2072CP unity-gain stable?
Yes-the TLE2072CP is explicitly designed for unity-gain stability, with a phase margin of 56° at unity gain (Section 6.4). Its 10.6 MHz unity-gain bandwidth and 32 V/μs slew rate are guaranteed under unity-gain conditions with 2 kΩ load and 20 pF capacitance. No external compensation is required for stable operation at gain = 1, simplifying design in buffer and follower configurations used in DMM input stages and oscilloscope probes.
