Product details
Overview
TLE2072ACD from Texas Instruments is a dual-channel, JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision applications. It delivers ±19V supply rails, 10MHz unity-gain bandwidth, 32V/μs slew rate, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate signal conditioning in oscilloscopes, electricity meters, and AC drive power stages.
For engineers reviewing the TLE2072ACD datasheet, TLE2072ACD pinout, TLE2072ACD application, or TLE2072ACD equivalent, key selection criteria include its SOIC-8 package, ±3.5mV max input offset voltage (25°C), rail-to-rail input capability, and guaranteed operation from 0°C to 70°C - critical for industrial instrumentation and test equipment design.
Technical Context
The TLE2072ACD uses Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, supporting differential inputs up to the supply rails. Its wide dynamic range (±19V) and high slew rate enable faithful amplification of fast, high-amplitude signals without clipping or distortion.
It features unity-gain stability, 56° phase margin, and low input bias current (±15pA typ), making it suitable for high-impedance sensor interfaces and active filter designs where leakage and settling time are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual - supports two independent amplification paths in one SOIC-8 package, reducing board space vs. discrete op-amps. |
| Supply Voltage Range | ±2.25V to ±19V - enables direct interfacing with high-voltage industrial sensors and legacy analog systems. |
| Input Offset Voltage | Max 3.5mV at 25°C - ensures minimal DC error in precision gain stages and sensor front-ends. |
| Unity-Gain Bandwidth | 10.6MHz - supports stable closed-loop operation up to ~10MHz, suitable for medium-speed data acquisition. |
| Slew Rate | 32V/μs - preserves fidelity of fast transients (e.g., pulse shaping, DAC output buffering) without slew-induced distortion. |
| Input Voltage Noise | 17nV/√Hz at 1kHz - lowers integrated noise floor in audio and measurement circuits compared to standard bipolar op-amps. |
| Input Bias Current | ±15pA typical - minimizes voltage error across high-value feedback or source impedances (>1MΩ). |
Pinout & Package
Package: SOIC-8 (D package), 4.9mm × 6mm body, surface-mount, tape-and-reel compatible (TLE2072ACDR variant available).
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | High-impedance JFET node accepting negative feedback or signal inversion; supports common-mode voltages to ±19V. |
| 2 | Non-Inverting Input (Channel 1) | High-Z input for reference or sensor signal; rail-to-rail common-mode range enables single-supply use with level-shifting. |
| 3 | Output (Channel 1) | Capable of ±20mA continuous output drive; swings within 1.5V of rails at full load for wide dynamic range. |
| 4 | V– (Negative Supply) | Connects to system ground or negative rail; thermal pad not present in SOIC-8 - θJA = 97.1°C/W. |
| 5 | Non-Inverting Input (Channel 2) | Independent second channel input; identical specs to Pin 2 - enables dual-path signal processing. |
| 6 | Inverting Input (Channel 2) | Second channel inverting input; matched offset and noise performance to Channel 1 for differential pair use. |
| 7 | Output (Channel 2) | Second independent output; fully specified for same load, temperature, and supply conditions as Pin 3. |
| 8 | V+ (Positive Supply) | Accepts up to +19V; internal protection limits absolute max to 38V differential between V+ and V–. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input stage | Accepts common-mode signals beyond supply rails by ±0.5V - eliminates need for external level-shifting in high-voltage sensor interfaces. |
| Low input bias current (±15pA) | Reduces voltage error across 10MΩ source impedances to <150μV - critical for piezoelectric and photodiode amplifiers. |
| 17nV/√Hz input voltage noise | Lowers total integrated noise in 10Hz–100kHz band by >5× vs. TL072 - improves SNR in digital multimeter front-ends. |
| ±19V supply capability | Directly interfaces with ±15V industrial control buses and legacy test equipment without external regulators or level translators. |
| Unity-gain stable | Operates reliably with gain = 1 without external compensation - simplifies design of buffers, active filters, and I/V converters. |
Applications
| Electricity Meter Front-End | Oscilloscope Vertical Amplifier |
|---|---|
Use Scenario: Amplifying low-level current-sense signals from shunt resistors or current transformers in Class 0.2 smart meters. IC Role / Device Role: Precision gain stage with high CMRR and low drift, driving ADC input while rejecting line-frequency interference.

IC Role / Device Role: High-common-mode rejection amplifier feeding isolation amplifier or comparator inputs. Use Value: ±19V supply and rail-to-rail input allow direct connection to gate-driver supplies; low IIB prevents offset drift in high-Z sense networks. | Use Scenario: Signal conditioning for 6½-digit DMMs measuring µV-level thermocouple outputs or nA-level leakage currents. IC Role / Device Role: Low-noise, low-drift instrumentation amplifier core with programmable gain and auto-zero support. Use Value: 17nV/√Hz noise and <3.5mV VIO enable 1µV resolution; JFET input avoids dielectric absorption errors in integrating capacitors. |
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 |
|---|---|---|---|
| TL072CD | Higher input offset (6mV max), higher noise (18nV/√Hz), lower slew rate (13V/μs), same SOIC-8 package. | Less suitable for precision metering or fast transient capture; acceptable for general-purpose audio or filtering. | Choose TL072CD only when cost is primary constraint and 3.5mV VIO or 32V/μs slew rate are not required. |
| OPA2134PA | Lower noise (8nV/√Hz), lower VIO (1mV max), but narrower supply range (±18V max) and no rail-to-rail input. | Better for ultra-low-noise audio or medical instrumentation; unsuitable for ±19V industrial rails or rail-to-rail input needs. | Select OPA2134PA when noise dominates design requirements and supply stays ≤±18V; avoid if input must swing to V±. |
Compared with TL072CD and OPA2134PA, the TLE2072ACD uniquely balances ±19V operation, rail-to-rail input, 3.5mV VIO, and 32V/μs slew rate - making it the only dual JFET op-amp in SOIC-8 meeting all four specs simultaneously for industrial test and measurement.

FAQ
What is the maximum supply voltage rating for the TLE2072ACD?
The TLE2072ACD has an absolute maximum supply voltage rating of ±19V (38V total differential), with recommended operating range from ±2.25V to ±19V. Operation beyond ±19V risks permanent damage. The device's wide supply range allows direct integration into legacy ±15V systems and newer high-dynamic-range industrial designs without external regulation - a key advantage over standard op-amps limited to ±15V.
Does the TLE2072ACD support rail-to-rail input operation?
Yes, the TLE2072ACD supports rail-to-rail input operation: its common-mode input voltage range extends to (V–) – 0.5V and (V+) + 0.5V, enabling signal acquisition beyond the supply rails. This feature eliminates level-shifting circuitry in applications like high-side current sensing or interfacing with ±19V sensor outputs - directly supported in the TLE2072ACD's electrical specifications under VICR parameter.
What is the input offset voltage specification for the TLE2072ACD at 25°C?
The TLE2072ACD has a maximum input offset voltage of 3.5mV at 25°C, per Table 4-2 in the official datasheet. This value applies specifically to the 'A' grade (TLE2072Axx) across all packages including the D (SOIC-8). The 'C' suffix denotes 0°C to 70°C operation, and the 'A' prefix indicates improved VIO grading - confirmed in the TLE2072ACD ordering table and electrical characteristics sections.
Is the TLE2072ACD unity-gain stable, and what is its phase margin?
Yes, the TLE2072ACD is unity-gain stable with a measured phase margin of 56° at unity gain (VCC± = ±5V or ±15V, CL = 25pF, RL = 2kΩ). This is explicitly verified in Sections 6.4 and 6.6 of the datasheet under φm (phase margin) - ensuring stable operation in buffer, follower, and active filter configurations without external compensation components.
What package type and dimensions does the TLE2072ACD use?
The TLE2072ACD uses the SOIC-8 (D) package: 4.9mm × 6mm nominal body size, 1.75mm max height, with standard 1.27mm lead pitch. This surface-mount package is RoHS-compliant, tape-and-reel ready (suffix R available), and compatible with automated PCB assembly - matching the mechanical data in Section 10 of the TLE207x datasheet and TI's official packaging documentation.
