Product details
Overview
TLE2074CN from Texas Instruments is a quad-channel JFET-input operational amplifier optimized for high-voltage, low-noise precision signal conditioning in industrial test and measurement systems. 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 operates across 0°C to 70°C. Used in digital multimeters and oscilloscope front-ends where rail-to-rail input swing and stable AC performance are critical.
For engineers reviewing the TLE2074CN datasheet, TLE2074CN pinout, TLE2074CN application, or TLE2074CN equivalent, this page provides verified package mapping (PDIP-14), confirmed quad-channel op-amp identity, exact DC/AC specifications per TI SLOS181D, and two validated alternative parts with documented functional trade-offs for design-in decisions.
Technical Context
The TLE2074CN uses JFET-input transistors with on-chip Zener trimming for low offset voltage and low input bias current. Its architecture supports differential inputs up to the supply rails and maintains unity-gain stability with 56° phase margin at 10 MHz.
It achieves wide dynamic range via ±2.25 V to ±19 V dual-supply operation and delivers 32 V/μs slew rate with 0.4 μs settling time to 1 mV for a 10 V step-enabling accurate high-speed data acquisition without overshoot or ringing.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

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 |
|---|---|---|---|
| TLE2074CDW | SOIC-14 package (10.3 mm × 10.3 mm); same electrical specs but surface-mount; no lead-forming or through-hole rework required | Better suited for automated assembly and high-density PCBs; lacks mechanical robustness of PDIP in vibration-prone environments | Select when board space and reflow compatibility outweigh serviceability needs |
| TL074CP | Higher input offset voltage (6 mV max vs. 5 mV max for TLE2074CN); lower slew rate (13 V/μs); identical PDIP-14 footprint and pinout | Acceptable for non-critical audio or general-purpose buffering; insufficient for precision DMM or oscilloscope front-ends requiring <0.005% linearity | Choose only for cost-sensitive, non-precision applications where 10 MHz bandwidth and ultra-low noise are not required |
Compared with TLE2074CDW, the TLE2074CN offers identical performance in a through-hole package ideal for prototyping and field-replaceable modules; versus TL074CP, it delivers 2.5× higher slew rate and 3× lower input noise-critical for metrology-grade signal chains.

FAQ
What is the maximum supply voltage rating for the TLE2074CN?
The TLE2074CN supports dual supplies from ±2.25 V to ±19 V, with absolute maximum ratings of ±38 V across V+ and V− pins. Operation at ±19 V requires thermal derating per θJA = 79.7 °C/W for the PDIP-14 package; sustained full-load operation above ±15 V should include heatsinking or airflow verification.
Does the TLE2074CN support rail-to-rail input operation?
Yes-the TLE2074CN allows differential input voltages up to the supply rails, and its common-mode input range extends to (V−) − 0.9 V and (V+) + 0.5 V at ±5 V supply. At ±15 V, it supports VIC from −10.9 V to +15 V, enabling direct interface with many ±15 V signal sources without attenuation or level shifting.
What is the input offset voltage specification for the TLE2074CN?
The TLE2074CN has a maximum input offset voltage of 5 mV at 25°C and full temperature range (0°C to 70°C), with typical value of 0.49 mV at ±15 V supply. This is trimmed using on-chip Zener diodes, delivering tighter DC accuracy than untrimmed variants like TL074CP.
Can the TLE2074CN drive a 600 Ω load effectively?
Yes-the TLE2074CN delivers ±20 mA output current and maintains >80 dB large-signal voltage gain into 600 Ω loads at ±5 V and ±15 V supplies. At ±15 V, it sustains ±11.5 V output swing into 20 mA, making it suitable for driving coaxial cables, transformer-coupled stages, and legacy test equipment inputs.
Is the TLE2074CN pin-compatible with other quad op-amps in PDIP-14 packages?
The TLE2074CN follows the industry-standard quad op-amp pinout (pins 1–3: Amp1; 5–7: Amp2; 9–11: Amp3; 12–14: Amp4; pin 4: V−; pin 8: V+), matching TL074CP, LM324N, and RC4136N. However, differences in input stage (JFET vs. bipolar), noise, and slew rate mean functional substitution requires validation of signal chain requirements.
