Product details
Overview
TLE2074ACN from Texas Instruments is a quad-channel, JFET-input operational amplifier optimized for high-precision, low-noise signal conditioning in industrial and test equipment. 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 3 mV max input offset voltage (25°C), enabling accurate amplification in digital multimeters and oscilloscope front-ends.
For engineers reviewing the TLE2074ACN datasheet, TLE2074ACN pinout, TLE2074ACN application, or TLE2074ACN equivalent, key selection criteria include rail-to-rail input operation, wide common-mode range (±10.9 V at ±15 V supplies), low 1.35–2.92 mA per-channel quiescent current, and compatibility with ±2.25 V to ±19 V dual supplies in PDIP-14 packaging.
Technical Context
The TLE2074ACN employs Excalibur JFET-input architecture with on-chip Zener trimming for DC precision, supporting stable unity-gain operation without external compensation. Its high slew rate (32 V/μs) and low phase margin (56° at unity gain) are validated under 2 kΩ load and 25 pF capacitive loading conditions.
It operates across 0°C to 70°C ambient temperature with guaranteed performance at ±5 V and ±15 V dual supplies, delivering full-swing output (±14.5 V at ±15 V, 20 mA load) and maintaining >85 dB CMRR and >90 dB PSRR over its rated temperature range.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables single-package implementation of multi-stage signal chains (e.g., differential input + gain + filtering + buffer). |
| GBW | 10.6 MHz - supports accurate amplification of signals up to ~1 MHz with ≤1% gain error in closed-loop configurations. |
| VIO (max) | 3 mV at 25°C - ensures ≤0.02% full-scale error in 15 V-range DMM front-ends without nulling circuitry. |
| Vn | 17 nV/√Hz at 1 kHz - preserves SNR in low-level sensor signal paths (e.g., thermocouple amplifiers, strain gauge bridges). |
| IIB | ±15 pA typical - minimizes voltage error across high-impedance sources (>100 MΩ), critical for piezoelectric and photodiode interfaces. |
| Supply Range | ±2.25 V to ±19 V - accommodates legacy ±15 V industrial systems and modern ±5 V embedded designs without level-shifting. |
| Slew Rate | 32 V/μs - enables faithful reproduction of fast transients (e.g., pulse-width modulated motor control feedback signals). |
Pinout & Package
Package: PDIP-14 (Plastic Dual In-line Package), 19.3 mm × 7.94 mm body size, through-hole mounting compatible with standard wave-solder processes.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | High-impedance JFET node; accepts differential signals up to supply rails (rail-to-rail input). |
| 2, 6, 10, 14 | Non-inverting Input (+) | High-impedance JFET node; common-mode range extends 0.9 V beyond rails at ±5 V supply. |
| 3, 7, 11, 12 | Output | Capable of ±14.5 V swing into 20 mA load at ±15 V supply; unity-gain stable. |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally to minimize noise coupling. |
| 8 | VCC+ | Positive supply rail connection; supports up to ±19 V absolute maximum rating. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±15 pA typical - eliminates significant offset drift in high-Z sensor interfaces (e.g., pH electrodes, capacitive touch). |
| Rail-to-rail input stage | Operates with inputs up to VCC+ + 0.5 V and VCC− − 0.5 V - simplifies design of level-shifting circuits in mixed-supply systems. |
| Low noise floor | 17 nV/√Hz at 1 kHz - maintains resolution in 6½-digit DMMs where 100 nV/√Hz would degrade effective number of bits. |
| Wide supply range | ±2.25 V to ±19 V - allows reuse across legacy ±15 V instrumentation and newer ±5 V portable test gear. |
| Unity-gain stability | No external compensation required - reduces BOM count and PCB area in gain-of-one buffers and active filters. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL074CD | Higher 25 nV/√Hz noise, 3 mV VIO max, same PDIP-14 package. | Limited to lower-bandwidth (<4 MHz) applications due to reduced GBW and slew rate (13 V/μs). | Select when cost sensitivity outweighs noise and speed requirements in non-critical signal paths. |
| OPA4134UA | Lower 8 nV/√Hz noise, 10 V/μs slew rate, SO-14 only - no PDIP option. | Requires PCB redesign for surface-mount assembly; superior audio-grade performance but higher cost. | Choose for ultra-low-noise audio or precision data acquisition where layout flexibility permits SMT-only design. |
Compared with TL074CD and OPA4134UA, the TLE2074ACN uniquely balances low noise (17 nV/√Hz), high speed (10.6 MHz, 32 V/μs), and through-hole PDIP-14 availability - making it optimal for industrial test equipment upgrades where legacy board compatibility and performance headroom are both essential.

FAQ
What is the maximum supply voltage rating for the TLE2074ACN?
The TLE2074ACN has an absolute maximum supply voltage rating of ±19 V across VCC+ and VCC−. Operation within the recommended range of ±2.25 V to ±19 V ensures specified performance; exceeding ±19 V risks permanent damage. This rating enables direct integration into legacy ±15 V industrial systems and high-voltage sensor interfaces without external regulators.
Does the TLE2074ACN support rail-to-rail input operation?
Yes, the TLE2074ACN supports rail-to-rail input operation: its common-mode input voltage range extends to VCC+ + 0.5 V and VCC− − 0.5 V. At ±15 V supply, this yields a usable input range of −15.5 V to +15.5 V - allowing direct interfacing with signals that swing near or beyond supply rails, such as those from certain transducers and isolated amplifiers.
What is the typical input bias current of the TLE2074ACN and why does it matter?
The TLE2074ACN exhibits a typical input bias current of ±15 pA, enabled by its JFET-input architecture. This ultra-low value minimizes voltage drop across high-impedance source impedances (e.g., >100 MΩ piezoelectric sensors or photodiode bias networks), preventing significant offset errors and drift - a critical factor in precision measurement front-ends where even nanoampere leakage degrades accuracy.
Is the TLE2074ACN unity-gain stable and what does that mean for circuit design?
Yes, the TLE2074ACN is unity-gain stable, meaning it can be configured as a voltage follower (gain = 1) without external compensation components. This simplifies design of high-impedance buffers and active filters, reduces component count, avoids stability tuning, and ensures predictable phase margin (56° at unity gain with 2 kΩ load and 25 pF capacitance) - directly improving time-to-market for instrumentation-grade analog circuits.
How does the noise performance of the TLE2074ACN compare to standard bipolar-input op-amps?
The TLE2074ACN delivers 17 nV/√Hz input voltage noise at 1 kHz - significantly lower than typical bipolar-input op-amps like the LM324 (35–40 nV/√Hz). This JFET-input advantage enables higher dynamic range in low-level signal amplification (e.g., thermocouple or strain gauge outputs), where noise dominates resolution limits. The TLE2074ACN's noise profile remains flat down to 10 Hz, supporting precision DC-coupled applications without 1/f noise penalties.
