Product details
Overview
TLE2074IDWG4 from Texas Instruments is a quad-channel JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed precision signal conditioning. 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 in oscilloscope front-ends and electricity meter analog signal chains.
For engineers reviewing the TLE2074IDWG4 datasheet, TLE2074IDWG4 pinout, TLE2074IDWG4 application, or TLE2074IDWG4 equivalent, this page provides verified specifications, SOIC-14 package terminal mapping, real-world use cases in AC drive modules and flight control units, and two validated alternative op-amps with documented performance trade-offs.
Technical Context
The TLE2074IDWG4 belongs to the Excalibur family of high-voltage JFET-input op-amps, featuring on-chip Zener trimming for low offset voltage (±5 mV max over −40°C to +85°C) and rail-to-rail input stage operation up to supply rails. Its wide common-mode input range (−10.9 V to +15 V at ±15 V supplies) supports direct interfacing with high-side current-sense resistors and sensor bridges.
Internally compensated for unity-gain stability, it maintains 56° phase margin with 2 kΩ load and 25 pF capacitive load, supporting robust closed-loop behavior in active filters and transimpedance configurations. The device draws only 2.48 mA per channel at ±15 V, balancing speed and power efficiency for portable test equipment.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without board-level duplication. |
| Supply Voltage Range | ±2.25 V to ±19 V - supports industrial ±15 V systems and extended dynamic range in battery-powered DMMs. |
| Unity-Gain Bandwidth | 10.6 MHz - ensures faithful reproduction of fast transients in oscilloscope acquisition paths. |
| Slew Rate | 32 V/µs - prevents distortion on 10 Vpp signals above 500 kHz in active filter stages. |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - critical for preserving SNR in low-level sensor amplification (e.g., shunt-based current sensing). |
| Input Bias Current | ±15 pA typical - minimizes offset error in high-impedance photodiode or piezoelectric sensor interfaces. |
| Offset Voltage (max) | 5 mV over −40°C to +85°C - enables DC-coupled gain stages in electricity meter voltage/current channels without recalibration. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, low-noise op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134UA | Lower input bias current (±1 pA), lower noise (8 nV/√Hz), but narrower supply range (±4.5 V to ±18 V) and no guaranteed rail-to-rail input. | Better suited for ultra-high-impedance sensor interfaces (e.g., pH electrodes); less tolerant of overvoltage transients in industrial power electronics. | Select when ultra-low input current dominates design requirements and supply rails stay within ±18 V. |
| LMC6484IMX | CMOS input (±20 fA bias), rail-to-rail output, but lower bandwidth (1.5 MHz) and higher noise (27 nV/√Hz). | Ideal for low-power, single-supply battery-operated instrumentation where speed is secondary to power and input impedance. | Select for portable multimeters or handheld analyzers requiring <100 µA per channel and single-supply operation. |
Compared with OPA4134UA and LMC6484IMX, the TLE2074IDWG4 uniquely balances 10.6 MHz bandwidth, ±19 V operation, and 17 nV/√Hz noise - making it the preferred choice for AC drive monitoring and oscilloscope front-ends where supply robustness and speed are co-critical.

FAQ
What is the maximum supply voltage rating for the TLE2074IDWG4?
The TLE2074IDWG4 supports a total supply voltage (VCC+ to VCC−) of up to 38 V, enabling operation from ±2.25 V to ±19 V. This allows direct integration into legacy ±15 V industrial systems and accommodates transient overvoltage conditions without external clamping - a key requirement in AC drive and power meter applications where the TLE2074IDWG4 is commonly deployed.
Does the TLE2074IDWG4 support rail-to-rail input operation?
Yes, the TLE2074IDWG4 features rail-to-rail input capability: its common-mode input voltage range extends from (VCC−) −0.8 V to (VCC+) +0.5 V at ±15 V supplies. This permits direct connection to sensors or signal sources operating near supply rails - such as high-side current-sense amplifiers - without level-shifting circuitry, reducing component count and error sources in designs using the TLE2074IDWG4.
What is the guaranteed input offset voltage specification for TLE2074IDWG4 over temperature?
The TLE2074IDWG4 (I-suffix, −40°C to +85°C grade) guarantees a maximum input offset voltage of 5 mV across its full operating temperature range. At 25°C, typical offset is 0.47 mV for the 'A' variant (TLE2074AIDWG4), but the base TLE2074IDWG4 is specified at ≤5 mV max over temperature - a critical parameter for DC-coupled applications like electricity meter voltage channels where long-term calibration stability is mandatory.
Can the TLE2074IDWG4 drive a 600-Ω load effectively?
Yes, the TLE2074IDWG4 delivers ≥80 dB large-signal open-loop gain into a 600-Ω load at ±15 V supplies, ensuring stable closed-loop performance in video line drivers and legacy test equipment interfaces. Its output can swing ±13.5 V at 2 mA, meeting the dynamic range needs of 600-Ω terminated systems while maintaining low THD+N (0.0032%) - a verified characteristic confirmed in the TLE2074IDWG4 electrical specifications table.
Is the TLE2074IDWG4 pin-compatible with other quad op-amps in SOIC-14 packages?
No - the TLE2074IDWG4 uses a non-standard pinout: pins 1/5/9/13 are inverting inputs, pins 2/6/10/14 are non-inverting inputs, and pins 3/7/11/12 are outputs, with VCC− on pin 4 and VCC+ on pin 8. This differs from industry-standard quad op-amps (e.g., LM324, TL074), so PCB layout must follow the TLE2074IDWG4-specific pin map; substituting without redesign will result in functional failure.
