Product details
Overview
TLE2074AIDW from Texas Instruments is a quad-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision signal conditioning. It delivers ±19V supply operation, 10MHz unity-gain bandwidth, 17nV/√Hz input voltage noise at 1kHz, ±15pA input bias current, and 32V/μs slew rate - enabling accurate amplification in oscilloscope front-ends and electricity meter analog signal chains.
For engineers reviewing the TLE2074AIDW datasheet, TLE2074AIDW pinout, TLE2074AIDW application, or TLE2074AIDW equivalent, this device supports demanding AC drive power stage monitoring, flight control unit sensor interfaces, and portable DMM front-end designs where rail-to-rail input capability, low offset drift, and wide dynamic range are critical selection criteria.
Technical Context
The TLE2074AIDW implements a JFET-input differential pair with on-chip Zener trimming for offset voltage stability, supporting operation across ±2.25V to ±19V supplies. Its unity-gain stable architecture enables direct use in gain-of-one configurations without external compensation.
It features rail-to-rail input common-mode range (extending beyond supply rails by up to 0.5V) and delivers full output swing within 1.5V of each rail at ±20mA load. The device maintains 56° phase margin with 25pF capacitive load and exhibits 98dB CMRR at ±15V supply.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without discrete op-amp duplication. |
| Supply Voltage Range | ±2.25V to ±19V - supports wide dynamic signal range in industrial and test equipment. |
| Input Voltage Noise | 17nV/√Hz at 1kHz - ensures minimal added noise in precision measurement front-ends. |
| Slew Rate | 32V/μs - allows faithful reproduction of fast transients in oscilloscope and data acquisition systems. |
| Unity-Gain Bandwidth | 10.6MHz - enables stable high-frequency closed-loop operation up to ~10MHz. |
| Input Bias Current | ±15pA max at 25°C - preserves accuracy in high-impedance sensor interfaces like piezoelectric transducers. |
| Offset Voltage Max | 3mV over −40°C to +85°C - reduces calibration burden in electricity meter and AC charging station analog stages. |
Pinout & Package
Package: SOIC-14 (DW), 10.3mm × 10.3mm body, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 10, 14 | Output | Four independent buffered outputs - each drives ≥20mA into resistive loads. |
| 2, 6, 9, 13 | Inverting Input (−) | Differential inputs accept signals up to ±0.5V beyond supply rails - simplifies level-shifting design. |
| 3, 7, 11, 12 | Non-inverting Input (+) | High-impedance JFET inputs minimize loading on source networks (e.g., filter RC nodes). |
| 4 | VCC− | Negative supply rail - must be decoupled locally with ≥0.1μF ceramic capacitor. |
| 8 | VCC+ | Positive supply rail - shared across all four amplifiers; requires local decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise JFET input stage | 17nV/√Hz input voltage noise enables sub-mV resolution in 16-bit+ data acquisition systems. |
| Zener-trimmed offset voltage | 3mV max over temperature eliminates need for manual nulling in production electricity meters. |
| Rail-to-rail input common-mode range | Operates with inputs up to (V−) − 0.5V and (V+) + 0.5V - accommodates unbuffered transducer outputs directly. |
| Wide supply range (±2.25V to ±19V) | Supports single-supply (e.g., +3.3V/0V) and dual-supply (±15V) topologies without redesign. |
| Unity-gain stable | Eliminates external compensation components in buffer, active filter, and gain-of-one configurations. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher input noise (18nV/√Hz), wider offset spread (6mV max), no Zener trimming. | Limited to cost-sensitive, non-metrology applications like audio preamps or basic instrumentation. | Acceptable where 3mV offset and 17nV/√Hz noise are not required; lower cost but reduced DC precision. |
| OPA4134UA | Lower noise (8nV/√Hz), higher supply current (4mA/ch), no rail-to-rail input, ±18V max supply. | Better suited for ultra-low-noise audio or medical EEG front-ends where power budget allows. | Preferred when noise dominates design; avoid in rail-to-rail input or >±18V applications. |
Compared with TL074CDR and OPA4134UA, the TLE2074AIDW uniquely balances low noise, tight offset, rail-to-rail input, and ±19V operation - making it optimal for industrial energy metering and test equipment where all four attributes are simultaneously required.

FAQ
What is the maximum supply voltage for the TLE2074AIDW?
The TLE2074AIDW supports a total supply voltage range of ±2.25V to ±19V, meaning the absolute maximum difference between VCC+ and VCC− is 38V. Operation beyond ±19V violates Absolute Maximum Ratings and risks permanent damage. This wide range enables use in both low-voltage portable DMMs and high-voltage industrial power monitors.
Does the TLE2074AIDW support rail-to-rail input operation?
Yes, the TLE2074AIDW accepts common-mode input voltages from (VCC−) − 0.5V to (VCC+) + 0.5V - exceeding the supply rails. This rail-to-rail input capability allows direct connection of unbuffered sensor outputs and simplifies design in applications like oscilloscope front-ends and AC charging station current sensing.
What is the typical input offset voltage specification for the TLE2074AIDW?
The TLE2074AIDW has a maximum input offset voltage of 3mV over the full operating temperature range (−40°C to +85°C). At 25°C, typical offset is ±300µV. This tight tolerance, achieved via on-chip Zener trimming, reduces system-level calibration overhead in precision applications such as electricity meters and flight control units.
Can the TLE2074AIDW drive a 50Ω load in oscilloscope applications?
Yes - the TLE2074AIDW delivers ±20mA output current per channel, sufficient to drive 50Ω loads to ±1V (at 20mA) or ±10V (at 200mA, within safe dissipation limits). Its 32V/μs slew rate and 10.6MHz bandwidth ensure fidelity for fast transient capture in oscilloscope vertical amplifiers using the TLE2074AIDW.
Is the TLE2074AIDW unity-gain stable?
Yes, the TLE2074AIDW is internally compensated for unity-gain stability. It maintains ≥56° phase margin with a 25pF capacitive load and requires no external compensation components in buffer, follower, or gain-of-one configurations - simplifying layout and improving reliability in high-frequency signal paths.
