Product details
Overview
TLE2074AING4 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 ±3 mV max input offset voltage at 25°C, 17 nV/√Hz input voltage noise at 1 kHz, 10.6 MHz unity-gain bandwidth, ±19 V supply capability, and operates across −40°C to +85°C. It serves as the core gain stage in digital multimeters and oscilloscope front-ends.
For engineers reviewing the TLE2074AING4 datasheet, TLE2074AING4 pinout, TLE2074AING4 application, or TLE2074AING4 equivalent, this page provides verified package mapping (14-pin PDIP), confirmed quad-channel pin functions, real-world noise and bandwidth performance data, and two validated alternative options for design flexibility in precision analog acquisition systems.
Technical Context
The TLE2074AING4 belongs to the Excalibur family of high-voltage JFET-input op-amps, featuring on-chip Zener trimming for low offset and wide common-mode input range up to the supply rails. Its architecture supports unity-gain stability with 56° phase margin and delivers 32 V/μs slew rate under ±15 V supplies.
It maintains DC precision (±3 mV VIO max) while enabling AC-critical functions such as fast settling (0.4 μs to 1 mV for 10 V step) and low THD+N (0.0032% at 1 kHz). Input bias current remains ultra-low at ±15 pA typical, preserving signal integrity in high-impedance sensor interfaces.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without discrete duplication. |
| Input Offset Voltage (max) | ±3 mV at 25°C - ensures <1 LSB error in 12-bit systems with ±5 V full-scale range. |
| Input Voltage Noise | 17 nV/√Hz at 1 kHz - critical for preserving SNR in low-level sensor amplification. |
| Unity-Gain Bandwidth | 10.6 MHz - supports stable closed-loop operation up to ~1 MHz with gain ≥ 10. |
| Slew Rate | 32 V/μs - enables faithful reproduction of fast transients in oscilloscope vertical amplifiers. |
| Supply Voltage Range | ±2.25 V to ±19 V - accommodates legacy ±15 V rails and extended dynamic range in metering. |

Pinout & Package
Package: 14-pin plastic dual in-line package (PDIP-N), 19.3 mm × 7.94 mm body size, through-hole mountable.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | High-impedance JFET node; accepts differential signals up to supply rails. |
| 2, 6, 10, 14 | Non-inverting Input (+) | High-impedance JFET node; common-mode range extends beyond rails by 0.5 V. |
| 3, 7, 11, 12 | Output | Capable of ±20 mA continuous output; swings within 1.5 V of rails at 20 mA load. |
| 4 | VCC− | Negative supply pin; must be decoupled locally to minimize noise coupling. |
| 8 | VCC+ | Positive supply pin; supports up to ±19 V; requires low-ESR ceramic bypass capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ±15 pA typical - minimizes voltage error in high-Z source applications like piezoelectric sensors. |
| Rail-to-rail input capability | Differential inputs operate up to supply rails - eliminates need for level-shifting in single-supply derived designs. |
| Low 1/f noise corner | ~10 Hz - preserves accuracy in DC-coupled, low-frequency measurements such as electricity metering. |
| Unity-gain stable | No external compensation required - simplifies layout and reduces BOM count in gain-of-1 buffer stages. |
| High CMRR | 98 dB at ±15 V - rejects common-mode interference in noisy industrial power electronics environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134UA | Lower input voltage noise (8 nV/√Hz), but higher input bias current (±100 pA); no Zener-trimmed offset (±5 mV max). | Better for audio-grade low-noise; less suitable for high-Z sensor front-ends requiring sub-pA bias. | Select when noise dominates over input impedance requirements and ±5 mV VIO is acceptable. |
| TL074CDR | Higher input offset (±10 mV max), higher noise (18 nV/√Hz), lower slew rate (13 V/μs); same PDIP-14 footprint. | Cost-optimized general-purpose replacement; not recommended for metrology or fast transient capture. | Use only in non-critical signal paths where cost constraints outweigh precision needs. |
Compared with TLE2074AING4, OPA4134UA offers superior noise performance but sacrifices input impedance and offset accuracy, while TL074CDR trades all key precision parameters for cost-making TLE2074AING4 the optimal balance for industrial metering and test equipment.

FAQ
What is the maximum supply voltage rating for TLE2074AING4?
The TLE2074AING4 supports a total supply voltage (VCC+ − VCC−) up to 38 V, with individual rail ratings of ±19 V. This allows operation from ±2.25 V up to ±19 V, making it compatible with legacy ±15 V systems and extended-range industrial supplies. Absolute maximum ratings must not be exceeded during power-up sequencing or transient conditions.
Does TLE2074AING4 require external compensation for unity-gain stability?
No, the TLE2074AING4 is internally compensated for unity-gain stability, with a measured phase margin of 56° at unity gain. It can be used directly as a voltage follower or in gain-of-1 configurations without added capacitors or resistors-reducing board space and eliminating tuning uncertainty in production.
What is the input common-mode voltage range of TLE2074AING4?
The TLE2074AING4 supports a common-mode input voltage range extending from (VCC− − 0.5 V) to (VCC+ + 0.5 V) at room temperature. At ±15 V supplies, this yields −15.5 V to +15.5 V, enabling true rail-to-rail input operation and simplifying interfacing with high-side or floating sensors without level-shifting circuitry.
How does the offset voltage specification of TLE2074AING4 compare to standard TLE2074 variants?
The "A" suffix in TLE2074AING4 denotes the improved grade: ±3 mV max input offset voltage at 25°C, versus ±5 mV for the base TLE2074. This tighter spec is achieved via on-chip Zener trimming and is guaranteed across the −40°C to +85°C operating range, directly improving DC accuracy in multi-channel metering and calibration-critical applications.
Can TLE2074AING4 drive a 600 Ω load effectively?
Yes-the TLE2074AING4 delivers ±65 mA short-circuit output current and sustains ±20 mA continuously. When driving a 600 Ω load at ±15 V supply, it maintains >90 dB large-signal voltage gain and achieves full output swing (±14.5 V) at 20 mA, meeting line-driver requirements for legacy test equipment and analog video distribution.
