Product details
Overview
TLE2074ACNG4 from Texas Instruments is a quad-channel JFET-input operational amplifier optimized for high-precision, low-noise signal conditioning in industrial and test equipment. 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 ±15 pA input bias current - enabling accurate amplification of weak sensor signals in oscilloscopes, digital multimeters, and AC drive power stage modules.
For engineers reviewing the TLE2074ACNG4 datasheet, TLE2074ACNG4 pinout, TLE2074ACNG4 application, or TLE2074ACNG4 equivalent, this page provides verified electrical specifications, SOIC-14 package layout, real-world use cases in high-speed data acquisition and precision metering, and validated alternative options for design continuity and sourcing flexibility.
Technical Context
The TLE2074ACNG4 implements a JFET-input differential pair with on-chip Zener trimming for low offset voltage (±2 mV max at 25°C), supporting rail-to-rail input operation up to ±19 V supplies. Its wide common-mode range (−10.9 V to +15 V at ±15 V supplies) and high CMRR (98 dB typical) ensure stability in noisy industrial environments.
It features unity-gain stability, 300 kHz maximum output-swing bandwidth, and 56° phase margin - making it suitable for closed-loop configurations without external compensation. The device operates across 0°C to 70°C and draws only 2.48 mA per channel at ±5 V.

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 |
|---|---|---|---|
| TL084CDR | Higher input noise (18 nV/√Hz), wider offset spread (±10 mV), no Zener trimming; same SOIC-14 package. | Lower precision; suitable for general-purpose audio or non-critical signal paths where cost is prioritized over DC accuracy. | Select when budget constraints outweigh need for <2 mV offset or 17 nV/√Hz noise performance. |
| OPA4134UA | Lower noise (8 nV/√Hz), lower bias current (±1 pA), but narrower supply range (±18 V max); SOIC-14, pin-compatible. | Better for ultra-low-noise audio or medical sensor front-ends; not rated for extended ±19 V operation. | Choose for highest fidelity in battery-powered or low-power precision systems where ±18 V supply suffices. |
Compared with TL084CDR and OPA4134UA, the TLE2074ACNG4 uniquely balances ±19 V operation, Zener-trimmed 2 mV offset, and 17 nV/√Hz noise - making it optimal for industrial test equipment requiring both wide dynamic range and DC stability without layout changes.

FAQ
What is the maximum supply voltage rating for the TLE2074ACNG4?
The TLE2074ACNG4 supports dual-supply operation from ±2.25 V up to ±19 V, with absolute maximum ratings of 0 V to 38 V across VCC+ and VCC− pins. This ±19 V capability enables direct integration into legacy ±15 V industrial systems and high-dynamic-range test equipment without level-shifting circuitry. Exceeding ±19 V may compromise long-term reliability or violate absolute maximum limits specified in the TI SLOS181D datasheet.
Does the TLE2074ACNG4 support rail-to-rail input operation?
Yes, the TLE2074ACNG4 supports rail-to-rail input operation: its common-mode input voltage range extends to within 0.9 V of either supply rail at ±5 V and to −10.9 V to +15 V at ±15 V supplies. This allows direct interfacing with sensors and DACs operating near supply rails without external level translation, improving design simplicity and signal fidelity in multi-stage analog chains.
What is the typical input bias current of the TLE2074ACNG4, and why does it matter?
The TLE2074ACNG4 has a typical input bias current of ±15 pA, enabled by its JFET-input architecture. This ultra-low value minimizes voltage error across high-impedance sources - such as photodiode transimpedance amplifiers, piezoelectric sensors, or high-value resistor dividers - preserving signal integrity and reducing calibration drift. At 25°C, bias current remains stable enough to support 16-bit measurement accuracy in precision metering applications.
Is the TLE2074ACNG4 unity-gain stable, and what is its phase margin?
Yes, the TLE2074ACNG4 is unity-gain stable with a measured phase margin of 56° at unity gain under standard test conditions (VI = 10 mV, CL = 25 pF, RL = 2 kΩ). This ensures robust closed-loop performance in buffer, inverter, and active filter configurations without external compensation components - simplifying PCB layout and improving reliability in high-density industrial control modules.
How does the TLE2074ACNG4 differ from the standard TLE2074CNG4?
The TLE2074ACNG4 is the "A" grade variant of the TLE2074 family, featuring tighter input offset voltage specification: ±2 mV maximum at 25°C versus ±3 mV for the standard TLE2074CNG4. Both share identical SOIC-14 packaging, pinout, bandwidth, noise, and supply range. The "A" grade is selected for applications demanding higher initial DC accuracy - such as factory-calibrated test instruments or revenue-grade energy meters - where reduced trim effort and improved channel matching are critical.
