Product details
Overview
TLE2072IDR from Texas Instruments is a dual JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision signal conditioning. It delivers 10 MHz unity-gain bandwidth, 32 V/µs slew rate, ±19 V supply capability, and 17 nV/√Hz input voltage noise at 1 kHz - enabling accurate amplification in oscilloscope front-ends and electricity meter sensor interfaces.
For engineers reviewing the TLE2072IDR datasheet, TLE2072IDR pinout, TLE2072IDR application, or TLE2072IDR equivalent, this device is selected for designs requiring rail-to-rail input operation, low bias current (±15 pA), wide common-mode range (±10.8 V at ±15 V supplies), and stable unity-gain performance without external compensation.
Technical Context
The TLE2072IDR uses Excalibur JFET-input architecture with on-chip Zener trimming for offset voltage control, supporting operation across −40°C to +85°C. Its differential input stage accepts signals up to the supply rails, and its internal compensation ensures unity-gain stability with 56° phase margin at 10 MHz.
It achieves low-noise performance via matched JFET pairs and optimized die layout, while maintaining high DC precision: max 6 mV input offset voltage over temperature and 29 µV/°C drift. Supply rejection exceeds 80 dB across ±5 V to ±15 V operation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth | 10.6 MHz unity-gain bandwidth enables accurate 1–2 MHz signal amplification without gain peaking. |
| Slew Rate | 32 V/µs supports fast transient response in data acquisition front-ends and active filter stages. |
| Input Noise | 17 nV/√Hz at 1 kHz ensures minimal added noise in precision sensor signal chains. |
| Supply Range | ±2.25 V to ±19 V allows direct interface with industrial ±15 V systems and high-dynamic-range sensors. |
| Input Bias Current | ±15 pA typical enables high-impedance source interfacing (e.g., piezoelectric sensors, photodiode transimpedance). |
| Offset Voltage | Max 6 mV over −40°C to +85°C reduces calibration burden in multi-channel metering applications. |
| CMRR | Min 80 dB ensures robust rejection of common-mode interference in noisy industrial environments. |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6.0 mm, surface-mount, tape-and-reel (R suffix denotes reel packaging).
| Pin/Terminal | Circuit Role | Design Meaning |

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 | Lower bandwidth (3 MHz), higher input noise (18 nV/√Hz), no guaranteed 17 nV/√Hz spec; same SOIC-8 package. | Not rated for ±19 V operation (max ±18 V); less suitable for high-dynamic-range metering requiring full ±15 V swing. | Select TL072CDR only for cost-sensitive, lower-bandwidth applications where 32 V/µs slew rate and 10 MHz GBW are not required. |
| OPA2134PA | Lower noise (8 nV/√Hz), higher CMRR (100 dB), but narrower supply range (±13.5 V max); DIP-8/SOIC-8 pinout differs (non-pin-compatible). | Superior audio-grade performance, but unsuitable for ±15 V industrial systems needing rail tolerance beyond ±13.5 V. | Choose OPA2134PA for low-noise audio or medical instrumentation; avoid in high-voltage metering or oscilloscope front-ends. |
Compared with TL072CDR and OPA2134PA, the TLE2072IDR uniquely balances 10 MHz bandwidth, ±19 V operation, and 17 nV/√Hz noise in a standard SOIC-8 footprint - making it optimal for industrial test equipment and precision energy monitoring where supply headroom and speed are critical.

FAQ
What is the maximum supply voltage for TLE2072IDR?
The TLE2072IDR supports a total supply voltage of up to 38 V, meaning it operates with dual supplies ranging from ±2.25 V to ±19 V. This ±19 V rating enables direct use in legacy ±15 V industrial systems and high-dynamic-range sensor interfaces without level-shifting circuitry - a key advantage over many general-purpose op-amps limited to ±15 V or less.
Does TLE2072IDR require external compensation for unity-gain stability?
No, the TLE2072IDR is internally compensated and unity-gain stable. Its phase margin is specified at 56° under unity-gain conditions with 25 pF capacitive load and 2 kΩ load resistance. This eliminates the need for external compensation networks, simplifying PCB layout and reducing bill-of-materials count in buffer and gain-of-1 configurations.
What is the input bias current specification for TLE2072IDR at 25°C?
The TLE2072IDR has a typical input bias current of ±15 pA at 25°C, with a maximum of ±175 pA over the full −40°C to +85°C operating range. This ultra-low bias current makes it ideal for interfacing with high-impedance sources such as photodiodes, piezoelectric sensors, and precision voltage dividers in electricity meters and scientific instruments.
How does the noise performance of TLE2072IDR compare at 1 kHz versus 10 kHz?
At 1 kHz, the TLE2072IDR exhibits 17 nV/√Hz input voltage noise - its specified low-noise floor. At 10 kHz, this drops to 4.4 nV/√Hz, reflecting its flat broadband noise profile above the 1/f corner. This behavior supports wideband applications like oscilloscope front-ends where consistent SNR across 100 kHz–1 MHz is essential.
Is TLE2072IDR pin-compatible with other dual op-amps in SOIC-8 packages?
The TLE2072IDR follows the industry-standard dual op-amp pinout (Pin 1: Ch1−, Pin 2: Ch1+, Pin 3: Ch1 Out, Pin 4: V−, Pin 5: Ch2+, Pin 6: Ch2−, Pin 7: Ch2 Out, Pin 8: V+), matching TL072, NE5532, and OPA2134. However, functional compatibility requires verification of bandwidth, noise, supply range, and input stage type - e.g., TL072 lacks ±19 V rating and has higher noise.
