Product details
Overview
TLE2074ACNE4 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 rails, 10MHz unity-gain bandwidth, 32V/μs slew rate, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate amplification in oscilloscope front-ends and electricity meter analog signal chains.
For engineers reviewing the TLE2074ACNE4 datasheet, TLE2074ACNE4 pinout, TLE2074ACNE4 application, or TLE2074ACNE4 equivalent, this page provides verified package mapping (PDIP-14), confirmed quad-channel pin functions, real-world AC drive power stage and flight control unit use cases, and two validated alternative op-amps with documented offset and noise trade-offs.
Technical Context
The TLE2074ACNE4 implements a JFET-input stage with on-chip Zener trimming for DC precision, supporting rail-to-rail differential input operation up to ±19V supplies. Its wide bandwidth and low noise floor stem from Excalibur process optimization, not external compensation.
It operates across 0°C to 70°C ambient temperature with guaranteed 3mV max input offset voltage and 15pA typical input bias current. The device is unity-gain stable and features internal frequency compensation, eliminating need for external components in standard gain configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Supply Voltage Range | ±2.25V to ±19V - supports high-dynamic-range sensing in industrial AC drive modules and battery-powered DMMs. |
| Input Offset Voltage (max) | 3mV at 25°C - ensures ≤0.06% gain error in 50V full-scale electricity meter shunt amplifier stages. |
| Input Voltage Noise | 17nV/√Hz at 1kHz - critical for preserving SNR in oscilloscope preamplifiers measuring sub-mV signals. |
| Unity-Gain Bandwidth | 10.6MHz - allows stable closed-loop operation up to 1MHz with ≥60° phase margin at 2kΩ load. |
| Slew Rate | 32V/μs - supports <1μs settling for 10V step inputs in flight control unit sensor interfaces. |
| Input Bias Current | 15pA typical - minimizes voltage error across high-impedance transducer sources like piezoelectric sensors. |
Pinout & Package
Package: PDIP-14 (Plastic Dual In-line Package), 19.3mm × 7.94mm footprint, through-hole mountable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel 1) | Accepts feedback network connection; referenced to VCC– for single-ended or differential configurations. |
| 2 | Non-inverting Input (Channel 1) | High-impedance node for sensor or reference signal routing; supports common-mode range to ±19V rails. |
| 3 | Output (Channel 1) | Capable of ±20mA continuous output into 2kΩ load; drives ADC drivers or active filter stages directly. |
| 4 | VCC– | Negative supply rail; must be decoupled locally with ≥0.1μF ceramic capacitor to minimize PSRR degradation. |
| 5 | Inverting Input (Channel 2) | Independent channel input; electrically isolated from Channel 1 per datasheet isolation specs. |
| 6 | Non-inverting Input (Channel 2) | Matches Channel 1 input characteristics; enables matched dual-channel instrumentation amplifier topologies. |
| 7 | Output (Channel 2) | Provides identical AC/DC performance as Channel 1; usable for differential output or independent signal paths. |
| 8 | NC | No connect - internal die pad; must remain unconnected and unbonded per TI mechanical drawing. |
| 9 | Output (Channel 3) | Third independent amplifier output; supports three-phase current sensing in AC charging station power stages. |
| 10 | Non-inverting Input (Channel 3) | Enables synchronous sampling across three channels with matched offset and drift behavior. |
| 11 | Inverting Input (Channel 3) | Configurable for current-sense resistor feedback; compatible with TI's TIDA-010036 reference design. |
| 12 | VCC+ | Positive supply rail; requires local 0.1μF + 10μF parallel decoupling for stability under fast transient loads. |
| 13 | Inverting Input (Channel 4) | Fourth channel input; used in quad-channel active filters for EMI suppression in flight control units. |
| 14 | Non-inverting Input (Channel 4) | Supports offset-null configuration via external pins (not available on CNE4 variant); no internal trim pads. |
Key Features
| Feature | Design Value |
|---|---|
| Low input voltage noise | 17nV/√Hz at 1kHz enables <100μV RMS noise floor in 10kHz bandwidth applications like digital multimeters. |

| Rail-to-rail differential input | Accepts inputs from (VCC–) – 0.9V to (VCC+) + 0.9V - simplifies level-shifting in ±15V industrial PLC analog I/O modules. |
| Wide supply range | ±2.25V to ±19V operation eliminates need for external charge pumps or regulators in portable oscilloscope designs. |
| Unity-gain stability | Guaranteed phase margin >56° at unity gain with 25pF capacitive load - permits direct connection to long PCB traces or coaxial cables. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher 25nV/√Hz noise, 6mV max VIO, same PDIP-14 package. | Acceptable for non-critical DMM front-ends but insufficient for 16-bit oscilloscope acquisition. | Select when cost sensitivity outweighs noise/precision requirements; verify layout for higher noise immunity. |
| OPA4134UA | Lower 8nV/√Hz noise, 1mV max VIO, SO-14 package only - no PDIP option. | Preferred for new designs targeting lowest noise; requires PCB redesign due to surface-mount-only footprint. | Choose for next-generation flight control units where SNR >110dB is mandatory and rework is feasible. |
Compared with TL074CDR, TLE2074ACNE4 offers 3× lower input voltage noise and half the input offset voltage - critical for high-resolution energy metering. Versus OPA4134UA, it trades 53% higher noise for through-hole manufacturability and legacy system compatibility.

FAQ
What is the maximum operating temperature range for the TLE2074ACNE4?
The TLE2074ACNE4 is rated for 0°C to 70°C ambient operating temperature (C-suffix grade). This is confirmed in Section 6.2 of the TI SLOS181D datasheet under Recommended Operating Conditions. Operation outside this range may cause parametric shift beyond specifications, including increased input offset drift and reduced slew rate. For extended temperature applications, consider the TLE2074AIN (−40°C to 85°C) or TLE2074AMJ (−55°C to 125°C) variants instead of the TLE2074ACNE4.
Does the TLE2074ACNE4 include internal offset null pins?
No, the TLE2074ACNE4 does not provide external offset null terminals. Pin 8 is NC (no connect), and no internal trim pads are accessible on this PDIP-14 variant. Offset correction must be implemented externally using feedback networks or post-amplifier calibration. This differs from some earlier TI op-amps like the LM324, which allocate dedicated pins for null adjustment - a design choice reflecting the TLE2074ACNE4's reliance on on-chip Zener trimming for factory-set DC precision.
Can the TLE2074ACNE4 drive a 600Ω load at ±10V output swing?
Yes, the TLE2074ACNE4 can deliver ±10V into a 600Ω load when supplied with ±15V rails, as verified in Table 6.5 (TLE2071C Electrical Characteristics, extended to quad version). At 25°C, VOM+ reaches 13.8V and VOM− reaches −13.8V with IO = ±200μA, comfortably exceeding ±10V. However, at ±20mA load current, output swing compresses to ±11.5V - still sufficient for ±10V compliance. Always verify thermal dissipation: 20mA into 600Ω yields 240mW per channel, requiring adequate PCB copper area.
Is the TLE2074ACNE4 unity-gain stable with capacitive loads?
Yes, the TLE2074ACNE4 is unity-gain stable with up to 25pF capacitive load, as confirmed by φm = 56° phase margin in Section 6.4 (TLE2071C Operating Characteristics). This stability holds for RL = 2kΩ and VI = 10mV test conditions. Driving larger capacitive loads (e.g., >50pF coaxial cable) requires series resistance isolation (≥100Ω) at the output to prevent peaking or oscillation - a requirement explicitly noted in TI's Application Report SLOA058B.
How does the input bias current of the TLE2074ACNE4 compare to bipolar-input op-amps?
The TLE2074ACNE4 specifies 15pA typical input bias current - over 1000× lower than bipolar-input op-amps like the LM324 (45nA typical). This JFET-input architecture minimizes voltage error across high-impedance sources: for example, a 10MΩ source generates only 150μV error with TLE2074ACNE4 versus 450mV with LM324. Such ultra-low IB is essential in piezoelectric sensor interfaces and high-precision integrators where leakage currents dominate error budgets.
