Product details
Overview
TLE2074AMJB from Texas Instruments is a quad-channel, JFET-input operational amplifier optimized for high-voltage, low-noise precision signal conditioning in demanding industrial and test equipment. It delivers ±19V supply operation, 10MHz unity-gain bandwidth, 17nV/√Hz input voltage noise at 1kHz, ±15pA input bias current, and ±3mV max input offset voltage over temperature - enabling accurate amplification in oscilloscopes, electricity meters, and flight control units.
For engineers reviewing the TLE2074AMJB datasheet, TLE2074AMJB pinout, TLE2074AMJB application, or TLE2074AMJB equivalent, this device is selected for high-dynamic-range analog front-ends where rail-to-rail input capability, low 1/f noise, and stable performance across −55°C to +125°C are required without sacrificing DC precision.
Technical Context
The TLE2074AMJB implements a JFET-input differential pair with on-chip Zener trimming for offset voltage stability, supporting differential input voltages up to the supply rails. Its Excalibur process enables wide supply range (±2.25V to ±19V) while maintaining low input bias current and high common-mode rejection (≥89dB).
It features unity-gain stability with 56° phase margin, 32V/μs slew rate, and low-output-impedance drive capability - making it suitable for driving capacitive loads in active filter stages and precision gain blocks without external compensation.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - supports four independent precision gain paths in one 14-pin CERDIP package. |
| Supply Voltage Range | ±2.25V to ±19V - enables direct interface with ±15V legacy industrial systems and high-headroom sensor signal chains. |
| Input Offset Voltage (max) | ±3mV over −55°C to +125°C - ensures minimal DC error in multi-stage instrumentation amplifiers without trimming. |
| Input Voltage Noise | 17nV/√Hz at 1kHz - critical for preserving SNR in low-level signal acquisition (e.g., strain gauge, thermocouple interfaces). |
| Unity-Gain Bandwidth | 10.6MHz - supports stable closed-loop operation up to ~1MHz with gain ≥10, suitable for active anti-aliasing filters. |
| Slew Rate | 32V/μs - allows full-scale step response within 0.4μs for 10V output swing, meeting speed requirements in DMM front-ends. |
| Input Bias Current | ±15pA typical at 25°C - minimizes voltage drop across high-impedance sources (e.g., piezoelectric sensors, pH electrodes). |
Pinout & Package
Package: J (CERDIP-14), 19.6mm × 7.9mm, hermetically sealed ceramic dual-in-line for military/industrial reliability and moisture resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 5, 9, 13 | Inverting Input (−) | High-impedance JFET node; accepts signals up to VCC− −0.8V and VCC+ +0.5V. |
| 2, 6, 10, 14 | Non-Inverting Input (+) | Differential input terminal; supports rail-to-rail common-mode range under specified conditions. |
| 3, 7, 11, 12 | Output | Capable of ±20mA continuous drive; outputs swing to within 1.5V of rails at 20mA load. |
| 4 | VCC− | Negative supply pin; must be decoupled locally to minimize noise coupling into all four channels. |
| 8 | VCC+ | Positive supply pin; shared across all four op-amps; requires low-ESR ceramic bypass capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input capability | Accepts common-mode voltages beyond supply rails by up to 0.5V - simplifies level-shifting in multi-supply systems. |
| On-chip Zener-trimmed offset | Eliminates need for external nulling circuitry in production test fixtures and embedded calibration loops. |
| Low 1/f noise corner | Equivalent input noise remains flat down to 0.1Hz - essential for DC-stable measurements in digital multimeters. |
| High CMRR & PSRR | ≥89dB CMRR and ≥80dB supply rejection ensure immunity to ground bounce and power rail ripple in noisy environments. |
| Hermetic CERDIP packaging | Guarantees long-term parameter stability and zero moisture-induced drift in aerospace and downhole applications. |

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 |
|---|---|---|---|
| OPA4134UA | Lower noise (8nV/√Hz), but only rated for −40°C to +85°C; no hermetic package option. | Preferred for commercial audio and lab equipment where extended temperature is not required. | Choose when lower noise dominates over temperature range and long-term drift stability. |
| LMC6084IMX | CMOS input (fA-level IIB), but 1.4MHz GBW and higher 40nV/√Hz noise; SOIC-14 only. | Better for ultra-high-impedance pH or ion-selective electrode interfaces, not high-speed precision. | Choose for picoampere-level source impedance compatibility, not bandwidth or noise-critical roles. |
Compared with OPA4134UA and LMC6084IMX, the TLE2074AMJB uniquely combines military-grade temperature range, hermetic reliability, 10MHz bandwidth, and 17nV/√Hz noise - making it irreplaceable in flight control, utility metering, and high-reliability test instrumentation where all three attributes are simultaneously required.

FAQ
What is the maximum operating temperature range for the TLE2074AMJB?
The TLE2074AMJB is rated for operation from −55°C to +125°C, verified per its M-suffix qualification and tested in the CERDIP (J) package. This extended range is confirmed in Section 6.2 of the TI datasheet SLOS181D and applies to all electrical characteristics unless otherwise noted. The TLE2074AMJB maintains ±3mV max input offset voltage across this full range, making it suitable for aerospace and downhole applications where thermal extremes are routine.
Does the TLE2074AMJB support rail-to-rail input operation?
Yes, the TLE2074AMJB supports differential input voltages up to the supply rails and common-mode input voltages extending 0.5V beyond VCC+ and 0.8V below VCC−, as specified in the Absolute Maximum Ratings and Recommended Operating Conditions tables. This rail-to-rail input capability is intrinsic to its JFET-input architecture and is validated across the full −55°C to +125°C range - enabling direct interfacing with sensors whose output swings near supply limits.
What is the noise performance of the TLE2074AMJB at low frequencies?
The TLE2074AMJB exhibits 17nV/√Hz input voltage noise at 1kHz and maintains flat spectral density down to 0.1Hz, with peak-to-peak equivalent input noise of 2.77μVPP over 0.1Hz–10Hz. This low 1/f noise corner is confirmed in Sections 6.4 and 6.10 of the datasheet and results from its Excalibur JFET process - directly enabling high-resolution DC measurements in digital multimeters and precision data loggers without external filtering.
Can the TLE2074AMJB drive a 600Ω load effectively?
Yes, the TLE2074AMJB delivers ±65mA short-circuit output current and sustains ±20mA continuously, allowing robust 600Ω drive capability. At ±15V supplies and 20mA load, output swing remains within 1.5V of each rail (VOM± = ±11.5V), and large-signal voltage gain exceeds 95dB into 600Ω. This is documented in Tables 6.5 and 6.9, confirming suitability for legacy test equipment interfaces and line-driver applications.
Is the TLE2074AMJB pin-compatible with other TLE2074 variants?
Yes, the TLE2074AMJB shares identical pinout with all TLE2074x variants in the J (CERDIP-14) package, including TLE2074MJ, TLE2074IJ, and TLE2074CJ. Pin functions - inputs, outputs, and supplies - are fully aligned per Figure 5-4 of the datasheet. However, electrical specifications differ significantly across suffixes (e.g., M vs. I vs. C), so substitution requires validation of offset, noise, and temperature performance for the target application.
