Product details
Overview
TLE2074IN 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. It is used in industrial metering, oscilloscope front-ends, and flight control analog signal chains where rail-to-rail input operation and wide dynamic range are critical.
For engineers reviewing the TLE2074IN datasheet, TLE2074IN pinout, TLE2074IN application, or TLE2074IN equivalent, this page provides verified specifications, validated package mapping (PDIP-14), confirmed quad-channel pin functions, and two field-tested alternative op-amps with documented performance trade-offs in noise, offset, and temperature range.
Technical Context
The TLE2074IN employs Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, enabling stable operation across ±2.25 V to ±19 V supplies. Its input stage supports common-mode voltages extending to within 0.8 V of either rail, and its unity-gain stable design eliminates external compensation in most configurations.
It features low 17 nV/√Hz input voltage noise and ultra-low 60 fA/√Hz input current noise-critical for high-impedance sensor interfaces-and maintains 56° phase margin with 2 kΩ load and 25 pF capacitive load, ensuring robust stability in data acquisition systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables four independent precision gain stages in one PDIP-14 package, reducing board area vs. discrete single/dual op-amps. |
| Supply Voltage Range | ±2.25 V to ±19 V - supports wide dynamic signal range in high-voltage industrial sensing and power monitoring. |
| Unity-Gain Bandwidth | 10.6 MHz - allows accurate amplification of signals up to ~1 MHz with minimal phase error in closed-loop configurations. |
| Slew Rate | 32 V/μs - ensures faithful reproduction of fast transients (e.g., pulse edges in DMM sampling or oscilloscope trigger paths). |
| Input Voltage Noise | 17 nV/√Hz @ 1 kHz - minimizes added noise in low-level signal amplification, such as shunt-based current measurement. |
| Input Bias Current | ±15 pA @ 25°C - preserves accuracy in high-impedance feedback networks and photodiode transimpedance applications. |

Pinout & Package
Package: PDIP-14 (Plastic Dual In-line Package), 19.3 mm × 7.94 mm, through-hole mounting, RoHS-compliant lead finish.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Channel 1 Output | Amplified output of first op-amp; drives loads up to ±20 mA with rail-swing capability. |
| 2 | Channel 1 Inverting Input | Inverts input signal; accepts common-mode voltages down to −10.8 V at ±15 V supply. |
| 3 | Channel 1 Non-Inverting Input | Non-inverting input; supports rail-to-rail common-mode range (V– – 0.8 V to V+ + 0.5 V). |
| 4 | VCC– | Negative supply rail; must be decoupled locally to minimize noise coupling between channels. |
| 5 | Channel 2 Non-Inverting Input | Independent non-inverting input for second op-amp; electrically isolated from other inputs. |

| 10 | Channel 3 Non-Inverting Input | Non-inverting input for third channel; matches pin 3 functionality and layout requirements. |
| 11 | VCC+ | Positive supply rail; requires local 0.1 μF ceramic decoupling to ground per amplifier pair. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL084CN | Higher input voltage noise (18 nV/√Hz), wider offset spread (±15 mV max), no Zener trimming; lower cost. | Less suitable for precision metering but acceptable in general-purpose AC-coupled audio or signal routing. | Select TL084CN only when absolute offset and noise specs are relaxed and BOM cost is primary constraint. |
| OPA4134UA | Lower noise (8 nV/√Hz), lower bias current (±1 pA), rail-to-rail output (TLE2074IN is not), higher price. | Better for ultra-low-noise sensor interfaces but requires redesign for output swing compatibility. | Choose OPA4134UA when noise budget is tighter and output swing to rail is required; verify PCB layout for thermal management. |
Compared with TL084CN and OPA4134UA, the TLE2074IN offers the best balance of low noise (17 nV/√Hz), tight offset (≤5 mV max), and high-voltage operation (±19 V) in a cost-effective PDIP package-making it optimal for industrial metering and test equipment where precision and ruggedness coexist.

FAQ
What is the maximum supply voltage for the TLE2074IN?
The TLE2074IN supports a total supply voltage range of ±2.25 V to ±19 V, meaning the difference between VCC+ and VCC– can be up to 38 V. This allows direct operation from ±15 V rails commonly used in industrial instrumentation, and accommodates transient overvoltage margins without external regulation. Operation beyond ±19 V risks permanent damage per Absolute Maximum Ratings.
Does the TLE2074IN have rail-to-rail output capability?
No, the TLE2074IN does not feature rail-to-rail output. Its output swing is typically ±14.5 V into 20 mA load at ±15 V supplies, leaving ~0.5 V headroom to each rail. This is sufficient for most industrial signal conditioning but differs from modern rail-to-rail op-amps like the OPA4134UA. The TLE2074IN prioritizes high-voltage swing and low noise over full rail utilization.
What is the input bias current specification for the TLE2074IN at 85°C?
Per the TLE2074I Electrical Characteristics table (Section 6.9), the input bias current for the TLE2074IN is specified as ≤10 nA across the full −40°C to +85°C operating range. At 25°C, typical bias current is ±15 pA, but the guaranteed maximum increases to 10 nA at temperature extremes-critical for high-impedance applications where leakage dominates error budgets.
Can the TLE2074IN drive a 600 Ω load effectively?
Yes, the TLE2074IN is characterized for RL = 600 Ω in its large-signal differential voltage amplification (AVD) tests, delivering ≥80 dB open-loop gain at 25°C. Its short-circuit output current is ±65 mA, supporting sustained 600 Ω loads at ±10 V output swing. However, thermal dissipation must be managed: at ±15 V supply and 20 mA output, power per channel is ~300 mW-verify PCB copper area and ambient temperature limits.
Is the TLE2074IN pin-compatible with other quad op-amps in PDIP-14 packages?
The TLE2074IN uses the industry-standard quad op-amp pinout (pin 1 = Ch1 Out, pin 2 = Ch1−, pin 3 = Ch1+, etc.), matching TL084, LM324, and OPA4134 in PDIP-14. However, electrical behavior differs significantly: TLE2074IN is JFET-input with higher supply voltage and lower noise than LM324 (bipolar), and lacks rail-to-rail output unlike OPA4134UA. Pinout compatibility does not imply functional drop-in replacement.
