Product details
Overview
TLE2074CDWR from Texas Instruments is a quad-channel, JFET-input operational amplifier optimized for high-voltage, low-noise, high-speed signal conditioning in precision analog systems. 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 5 mV max input offset voltage (25°C), making it suitable for oscilloscope front-ends and electricity metering circuits.
For engineers reviewing the TLE2074CDWR datasheet, TLE2074CDWR pinout, TLE2074CDWR application, or TLE2074CDWR equivalent, this page provides verified specifications, SOIC-14 package layout, real-world use cases in AC drive modules and flight control units, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TLE2074CDWR employs Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, enabling rail-to-rail differential input operation up to ±19 V supplies. Its wide dynamic range supports high-fidelity acquisition of fast transients without clipping.
It features unity-gain stability, 56° phase margin, and low 60 fA/√Hz input current noise-critical for high-impedance sensor interfaces. The device operates across 0°C to 70°C and maintains 10.6 MHz bandwidth and 32 V/μs slew rate under ±5 V and ±15 V conditions.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-stage filtering or simultaneous signal conditioning in 4-channel data acquisition systems |
| Supply Voltage Range | ±2.25 V to ±19 V - supports industrial high-voltage rails without external level-shifting circuitry |
| Unity-Gain Bandwidth | 10.6 MHz - ensures accurate reproduction of signals up to ~1.7 MHz at 0.1 dB gain flatness |

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 |
|---|---|---|---|
| TL074CDR | Lower slew rate (13 V/μs), higher input noise (18 nV/√Hz), no Zener-trimmed offset (max 10 mV) | Acceptable for audio and general-purpose signal conditioning but insufficient for 10+ MHz transient capture | Choose TL074CDR only when cost sensitivity outweighs bandwidth/noise requirements |
| OPA4134UA | Lower noise (8 nV/√Hz), lower input bias (±10 pA), but narrower supply range (±18 V max) and no guaranteed ±19 V operation | Better for ultra-low-noise audio or medical instrumentation; less robust in high-voltage industrial environments | Select OPA4134UA when sub-10 nV/√Hz noise is mandatory and supply stays ≤±18 V |
Compared with TL074CDR and OPA4134UA, the TLE2074CDWR uniquely balances ±19 V operation, 10.6 MHz bandwidth, and 17 nV/√Hz noise-making it optimal for high-voltage, high-fidelity acquisition where rail margin and speed are jointly constrained.

FAQ
What is the maximum supply voltage rating for the TLE2074CDWR?
The TLE2074CDWR supports a total supply voltage span of up to 38 V, with individual rails rated from ±2.25 V to ±19 V. This allows operation at ±19 V, enabling direct interfacing with high-voltage industrial buses without external attenuation. Absolute maximum ratings specify VCC+ = 38 V and VCC− = 0 V, but symmetric ±19 V is the validated operating limit per TI SLOS181D Section 6.1.
Does the TLE2074CDWR support rail-to-rail input operation?
Yes, the TLE2074CDWR accepts differential input voltages extending to (V−) − 0.5 V and (V+) + 0.5 V, as confirmed in Section 6.2 of the datasheet. This rail-to-rail differential input capability permits direct connection to overvoltage-tolerant sensors and eliminates the need for external clamping diodes in many industrial signal chains.
What is the typical input offset voltage for the TLE2074CDWR at room temperature?
The TLE2074CDWR has a maximum input offset voltage of 5 mV at 25°C, as specified in Table 4-3 for the C-suffix (0°C to 70°C) grade. Typical values are lower-TI's characterization shows ~0.49 mV at ±15 V supply-but design margins must use the 5 mV max value for worst-case error analysis in the TLE2074CDWR.
Can the TLE2074CDWR drive a 600 Ω load effectively?
Yes-the TLE2074CDWR delivers ±65 mA short-circuit output current and sustains ±14.5 V output swing into 20 mA loads at ±15 V supply. At 600 Ω, full-scale output remains within specification: for example, a 10 Vpp signal draws only ~16.7 mA peak, well within its linear output capability as verified in Section 6.5's VOM± data.
Is the TLE2074CDWR unity-gain stable?
Yes, the TLE2074CDWR is explicitly unity-gain stable, with 56° phase margin measured at unity gain with 25 pF capacitive load (Section 6.4). Its internal compensation ensures stable operation in follower, inverter, and active filter configurations without external compensation components.
