Product details
Overview
TLE2074CDW 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 TLE2074CDW datasheet, TLE2074CDW pinout, TLE2074CDW application, or TLE2074CDW equivalent, this device is selected where rail-to-rail input operation, low 1/f noise, wide dynamic range, and quad-channel integration are required in industrial test equipment, energy measurement systems, and high-fidelity data acquisition stages.
Technical Context
The TLE2074CDW 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 10 MHz gain-bandwidth product and 56° phase margin ensure robust unity-gain stability with capacitive loads up to 25 pF.
It achieves low 17 nV/√Hz noise floor at 1 kHz while maintaining 32 V/µs slew rate and 0.5 µV/°C typical input offset drift - making it suitable for high-resolution, wideband analog signal paths where both speed and precision are critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without inter-device matching errors. |
| Supply Voltage Range | ±2.25 V to ±19 V - supports wide dynamic signal range in high-voltage industrial sensing and power monitoring. |
| Gain-Bandwidth Product | 10.6 MHz - ensures stable unity-gain operation and preserves fidelity in 1–2 MHz sensor or ADC driver applications. |
| Slew Rate | 32 V/µs - enables faithful reproduction of fast transients in oscilloscope vertical amplifiers and pulse conditioning circuits. |
| Input Voltage Noise | 17 nV/√Hz @ 1 kHz - minimizes added noise in low-level signal amplification (e.g., shunt-based current sensing). |
| Input Bias Current | ±15 pA max @ 25°C - preserves accuracy in high-impedance source interfaces like piezoelectric sensors or photodiode transimpedance stages. |
| Common-Mode Input Range | Extends to within 1.9 V of rails (±15 V supply) - allows direct interfacing with rail-referenced sensors and DAC outputs. |
Pinout & Package
Package: SOIC-14 (DW), 10.3 mm × 10.3 mm body, surface-mount, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | High-impedance JFET node for each op-amp channel; accepts signals up to supply rails. |
| 2, 6, 10, 12 | Non-inverting Input (+) | High-impedance JFET node; supports rail-to-rail common-mode operation. |
| 3, 7, 11, 14 | Output | Capable of ±20 mA drive into 600 Ω load; swings to within 1.5 V of rails at full load. |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally for noise-sensitive applications. |
| 8 | VCC+ | Positive supply rail connection; shared across all four amplifiers; requires local 0.1 µF ceramic bypass. |
Key Features
| Feature | Design Value |
|---|---|
| Low input voltage noise | 17 nV/√Hz at 1 kHz - reduces integrated noise in bandwidth-limited precision measurement paths. |
| Rail-to-rail input stage | Operates with inputs up to ±19 V supply rails - eliminates level-shifting in high-side current sensing and HV DAC buffering. |
| Unity-gain stable | No external compensation required - simplifies layout and improves phase margin in gain-of-1 configurations. |
| Excalibur JFET input | ±15 pA input bias current - maintains accuracy with >1 MΩ source impedances without significant offset error. |
| Wide supply range | ±2.25 V to ±19 V - supports legacy ±15 V systems and modern ±5 V/±12 V industrial designs with one part number. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CDR | Higher 18 nV/√Hz noise, lower 3 MHz GBW, ±13 V max supply, no Zener-trimmed offset. | Lower cost but unsuitable for >1 MHz precision or ±15 V+ systems requiring rail-to-rail input. | Select only for non-critical, low-bandwidth general-purpose use where TLE2074CDW's noise/speed advantages are unnecessary. |
| OPA4134UA | Lower 8 nV/√Hz noise, 4 MHz GBW, ±18 V supply, FET input, but higher 100 pA bias current. | Better noise performance but insufficient bandwidth for fast transient capture; not unity-gain stable without compensation. | Prefer when ultra-low noise dominates over speed; avoid where ≥10 MHz closed-loop bandwidth or uncompensated unity-gain is required. |
Compared with TL074CDR and OPA4134UA, the TLE2074CDW uniquely balances 10 MHz bandwidth, 17 nV/√Hz noise, ±19 V operation, and guaranteed unity-gain stability - making it the optimal choice for high-fidelity, wide-dynamic-range, multi-channel industrial signal conditioning where all three attributes are simultaneously required.

FAQ
What is the maximum supply voltage rating for the TLE2074CDW?
The TLE2074CDW supports a total supply voltage (VCC+ to VCC−) of up to 38 V, allowing operation from ±2.25 V to ±19 V. This wide range enables compatibility with legacy ±15 V systems and modern high-dynamic-range industrial supplies. Absolute maximum ratings must not be exceeded - sustained operation above ±19 V risks permanent damage.
Does the TLE2074CDW require external compensation for unity-gain stability?
No, the TLE2074CDW is internally compensated and unity-gain stable. It maintains ≥56° phase margin with 25 pF capacitive load at unity gain, eliminating the need for external compensation networks. This simplifies PCB layout and improves reliability in gain-of-1 configurations such as voltage followers and active filters.
What is the input offset voltage specification for the TLE2074CDW at 25°C?
The TLE2074CDW has a maximum input offset voltage of 5 mV at 25°C, with typical value of 0.49 mV at ±15 V supply. This is specified for the "C" grade (0°C to 70°C ambient), and applies across all four channels. The offset remains stable over time due to Excalibur's Zener-trimmed JFET input structure.
Can the TLE2074CDW drive a 600 Ω load effectively?
Yes - the TLE2074CDW delivers ±20 mA output current per channel, enabling direct drive of 600 Ω loads with ≤1.5 V headroom from either rail at ±15 V supply. Output swing is specified down to ±11.5 V at 20 mA, ensuring full-scale signal integrity in video line drivers and legacy test equipment interfaces.
Is the TLE2074CDW pin-compatible with other SOIC-14 quad op-amps like the TL074?
No - the TLE2074CDW uses a non-standard pinout: VCC− is on Pin 4 and VCC+ on Pin 8, whereas TL074 places VCC− on Pin 4 and VCC+ on Pin 11. Swapping them causes functional failure. Always verify pin mapping using Figure 5-5 (DW package) from the TI SLOS181D datasheet before board layout.
