Product details
Overview
TLE2074AIN 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, ±19 V supply capability, 17 nV/√Hz input voltage noise at 1 kHz, ±15 pA input bias current, and 3 mV max input offset voltage (−40°C to +85°C), enabling accurate amplification in oscilloscopes, electricity meters, and AC drive power stages.
For engineers reviewing the TLE2074AIN datasheet, TLE2074AIN pinout, TLE2074AIN application, or TLE2074AIN equivalent, this page provides verified specifications, package mapping to PDIP-14, functional context for rail-to-rail input operation and high-voltage dynamic range, and validated alternative options for design continuity and sourcing resilience.
Technical Context
The TLE2074AIN uses Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, supporting differential inputs up to the supply rails and operating stably from ±2.25 V to ±19 V. Its 32 V/μs slew rate and 10.6 MHz gain-bandwidth product enable fast settling (0.4 μs to 1 mV) in closed-loop configurations without oscillation.
Designed for wide common-mode input range (−10.8 V to +15 V at ±15 V supplies) and high CMRR (98 dB typical), it maintains accuracy under mismatched source impedances and noisy supply conditions-critical in multi-channel data acquisition and analog front-end signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact 4-channel signal conditioning without inter-device matching drift. |
| Supply Voltage Range | ±2.25 V to ±19 V - supports high-dynamic-range sensing in industrial power monitoring and motor control. |
| Input Offset Voltage (max) | 3 mV over −40°C to +85°C - ensures <0.02% gain error in 100 mV–1 V measurement ranges. |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - preserves SNR in low-level sensor interfaces like shunt-based current sensing. |
| Gain-Bandwidth Product | 10.6 MHz - allows stable unity-gain buffer or 10× gain configuration up to ~1 MHz. |
| Slew Rate | 32 V/μs - supports clean 10 VPP output at 100 kHz without slewing distortion. |
| Input Bias Current | ±15 pA (typ) - minimizes voltage error across high-impedance sources (>100 MΩ). |
Pinout & Package
Package: PDIP-14 (N), 19.3 mm × 7.94 mm, through-hole mounting compatible with legacy industrial PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | High-impedance JFET node; accepts signals up to supply rails with minimal loading. |
| 2, 6, 10, 14 | Non-inverting Input (+) | Matched to inverting input; supports rail-to-rail common-mode operation. |
| 3, 7, 11, 12 | Output | Capable of ±20 mA continuous drive into 600 Ω loads; rail-swing limited by load current. |
| 4 | VCC− | Negative supply pin; must be decoupled locally to minimize PSRR degradation. |
| 8 | VCC+ | Positive supply pin; supports up to ±19 V; requires 0.1 μF ceramic + 10 μF bulk capacitance. |
Key Features
| Feature | Design Value |
|---|---|
| Low-noise JFET input stage | 17 nV/√Hz at 1 kHz enables sub-μV resolution in precision DMMs and digitizers. |
| Rail-to-rail input common-mode range | Operates with inputs up to VCC± - eliminates level-shifting in single-supply sensor interfaces. |
| Excalibur process with Zener trimming | 3 mV max VIO over temperature ensures stable calibration in electricity meter reference paths. |
| Unity-gain stable architecture | No external compensation required - simplifies layout in high-density multichannel DAQ boards. |
| Wide supply range (±2.25 V to ±19 V) | Supports direct connection to ±15 V industrial bus rails without regulators or LDOs. |
Applications
| Application 1 | Application 2 |
|---|---|
Use Scenario: Signal conditioning for shunt-based current measurement in AC drive inverters. IC Role / Device Role / Timing Role: Quad op-amp buffers and amplifies differential voltage across precision shunts before ADC sampling. Use Value: Low 17 nV/√Hz noise preserves resolution at 100 A full-scale; ±19 V supply accommodates high-side sensing without level shifters. |
Use Scenario: Analog front-end for portable digital multimeters (DMMs) requiring 4½-digit accuracy. IC Role / Device Role / Timing Role: Configured as programmable-gain amplifier and filter driver for dual-slope ADC input path. Use Value: 3 mV max VIO and ±15 pA IIB minimize zero-error drift and input loading on high-Z divider networks. |
| Application 3 | Application 4 |

Use Scenario: Reference voltage buffering and error amplification in smart electricity meters. IC Role / Device Role / Timing Role: Precision buffer for metrology-grade voltage references and current transformer secondary signals. Use Value: High CMRR (98 dB) rejects supply ripple; low IIB prevents drift in long-term energy accumulation algorithms. |
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 25 nV/√Hz noise, 6 mV max VIO (0°C–70°C), no extended temp rating. | Limited to commercial-temp instrumentation; unsuitable for AC charging station ambient extremes. | Select when cost sensitivity outweighs noise and temperature stability requirements. |
| OPA4134UA | Lower 8 nV/√Hz noise, 1 mV max VIO, but only ±18 V max supply and higher 4.5 mA/ch ICC. | Better SNR in audio and low-power portable DMMs; less suitable for ±19 V industrial rails. | Choose for ultra-low-noise battery-powered designs where supply headroom is constrained. |
Compared with TL074CDR, TLE2074AIN offers lower noise and guaranteed performance over −40°C to +85°C; versus OPA4134UA, it trades 9 nV/√Hz noise for wider supply range and lower quiescent current-making it optimal for high-voltage, thermally demanding industrial signal chains.

FAQ
What is the maximum supply voltage for the TLE2074AIN?
The TLE2074AIN supports a total supply voltage (VCC+ to VCC−) of up to 38 V, corresponding to ±19 V operation. This allows direct interfacing with standard ±15 V industrial rails while preserving 4 V of headroom-critical for transient immunity in AC drive modules and metering front-ends where supply bounce is common.
Does the TLE2074AIN support rail-to-rail input operation?
Yes, the TLE2074AIN accepts common-mode input voltages from (VCC−) − 0.8 V to (VCC+) + 0.5 V at ±15 V supplies-enabling true rail-to-rail input functionality. This eliminates the need for external level-shifting circuitry when conditioning signals referenced to system ground or supply rails in oscilloscope vertical amplifiers and DMM input stages.
What is the input offset voltage specification for TLE2074AIN over temperature?
The TLE2074AIN guarantees a maximum input offset voltage of 3 mV across the full operating range of −40°C to +85°C. This is tighter than the standard TLE2074IN (5 mV max), reflecting the "A" grade's enhanced Zener-trimmed precision-essential for maintaining calibration integrity in electricity meters and flight control unit analog sensors.
Can the TLE2074AIN drive a 600 Ω load effectively?
Yes, the TLE2074AIN delivers ±20 mA output current per channel and maintains >90 dB large-signal voltage gain into 600 Ω loads at ±15 V supplies. Its output swing reaches ±14.5 V at 20 mA, making it suitable for driving legacy 600 Ω coaxial inputs in oscilloscope and spectrum analyzer signal paths without external buffers.
Is the TLE2074AIN pin-compatible with other quad op-amps in PDIP-14 packages?
The TLE2074AIN follows the industry-standard quad op-amp pinout (dual inverting/non-inverting inputs per half, shared supplies), matching TL074, LM324, and OPA4134 in PDIP-14. However, its JFET input structure, ±19 V rating, and thermal characteristics differ-PCB layout reuse is possible, but electrical validation is required for noise, stability, and supply margin.
