Texas Instruments TLE2074MJ

Overview

TLE2074MJ from Texas Instruments is a quad-channel JFET-input operational amplifier optimized for high-voltage, low-noise precision signal conditioning in 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 operates across −55°C to +125°C. It serves as the core gain stage in high-speed data acquisition front-ends and oscilloscope analog signal paths.

For engineers reviewing the TLE2074MJ datasheet, TLE2074MJ pinout, TLE2074MJ application, or TLE2074MJ equivalent, key selection criteria include its extended temperature range (−55°C to +125°C), ceramic DIP (J) package with 14 pins, JFET-input architecture enabling ultra-low bias current, and guaranteed low-noise performance in high-impedance sensor interfaces and precision instrumentation.

Technical Context

The TLE2074MJ implements a dual-differential-pair JFET input stage with on-chip Zener trimming for offset voltage stability, enabling DC precision without external nulling. Its wide supply range (±2.25V to ±19V) supports rail-to-rail differential input operation up to the supply rails, while maintaining 32V/μs slew rate and 56° phase margin for unity-gain stability.

It features high open-loop gain (>90dB at 10kΩ load), 89dB common-mode rejection ratio (CMRR), and 99dB supply-voltage rejection ratio (SVR) - all specified over its full military-grade temperature range. Input resistance exceeds 1TΩ, and input capacitance is 2.5pF differential, making it suitable for high-Z photodiode and piezoelectric transducer amplification.

FAQ

What is the maximum supply voltage for the TLE2074MJ?

The TLE2074MJ supports a maximum supply voltage of ±19V, enabling operation in high-dynamic-range analog circuits such as industrial process controllers and high-voltage sensor interfaces. This rating is absolute maximum and applies across its full −55°C to +125°C operating range. Operation above ±19V risks permanent damage, and design margins should maintain at least ±0.5V headroom per rail.

Does the TLE2074MJ require external compensation for unity-gain stability?

No, the TLE2074MJ is internally compensated and unity-gain stable - no external capacitors or resistors are needed for stable operation at gain = 1. This is confirmed in Section 6.4 of the datasheet, where phase margin is specified at 56° under unity-gain conditions with 25pF load. External compensation is only necessary if driving heavy capacitive loads (>100pF) directly.

What is the input bias current specification for the TLE2074MJ at −55°C?

At −55°C, the TLE2074MJ exhibits a maximum input bias current of 60nA, as specified in Table 6.11 (TLE2071M Electrical Characteristics) and confirmed for the quad variant via family-wide characterization. This value reflects worst-case JFET leakage at cold extremes and remains well below bipolar-input alternatives, preserving accuracy in high-impedance transducer interfaces.

Can the TLE2074MJ drive a 600Ω load at ±10V output swing?

Yes, the TLE2074MJ can deliver ±10V output swing into a 600Ω load when supplied with ±15V rails, as verified by VOM± specifications in Table 6.5 (TLE2071C Electrical Characteristics at ±15V). At 25°C, it achieves ±13.5V swing into 2mA load - comfortably exceeding ±10V at 16.7mA - with THD+N maintained at 0.0032% at 1kHz.

Is the TLE2074MJ pin-compatible with other TLE2074 variants like TLE2074CN?

Yes, all TLE2074 variants - including TLE2074MJ, TLE2074CN, TLE2074ACDW, and TLE2074IN - share identical 14-pin CDIP (J), PDIP (N), SOIC (DW), and CFP (W) pinouts per Figure 5-4 and Figure 5-5 of the datasheet. Pin functions (inputs, outputs, supplies) are electrically and physically identical; only package construction, temperature grade, and offset voltage binning differ between variants.
