Product details
Overview
TLE2074AMFKB 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, 32V/μs slew rate, and 17nV/√Hz input voltage noise at 1kHz - enabling accurate amplification of fast, low-amplitude signals in oscilloscopes and electricity meters.
For engineers reviewing the TLE2074AMFKB datasheet, TLE2074AMFKB pinout, TLE2074AMFKB application, or TLE2074AMFKB equivalent, this device is selected for designs requiring rail-to-rail input capability, low bias current (±15pA), wide common-mode range (±10.9V at ±15V supplies), and stable performance across −55°C to +125°C operating temperature.
Technical Context
The TLE2074AMFKB uses JFET-input transistors with on-chip Zener trimming for offset voltage control, supporting high-impedance sensor interfaces without loading. Its unity-gain stable architecture and 56° phase margin ensure robust closed-loop behavior with capacitive loads up to 25pF.
It operates over ±2.25V to ±19V supplies and accepts differential inputs up to the supply rails. The device maintains 10MHz gain-bandwidth product and 32V/μs slew rate across its full temperature range, making it suitable for high-speed data acquisition front-ends where DC precision and AC fidelity are both critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-channel signal conditioning without inter-device matching drift. |
| Supply Voltage Range | ±2.25V to ±19V - supports wide dynamic signal range in high-voltage industrial systems. |
| Input Noise Density | 17nV/√Hz at 1kHz - preserves SNR in low-level analog measurement paths like DMMs and metering front-ends. |
| Slew Rate | 32V/μs - ensures faithful reproduction of fast transients in oscilloscope vertical amplifiers and pulse conditioning. |
| Input Bias Current | ±15pA max - minimizes voltage error in high-impedance photodiode or piezoelectric sensor interfaces. |
| Unity-Gain Bandwidth | 10.6MHz - provides sufficient small-signal bandwidth for active filtering and buffer stages in 1–5MHz acquisition systems. |
| Operating Temperature | −55°C to +125°C - qualified for under-hood automotive, avionics, and downhole instrumentation environments. |
Pinout & Package
LCCC-20 (FK) package: hermetically sealed ceramic leadless chip carrier with 20 terminals, 8.89mm × 8.89mm footprint, suitable for high-reliability military and aerospace applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4 | Offset Null 1 / IN+ / IN− / Output (Ch1) | Channel 1 differential input pair and output; pins 1 & 4 support offset trim via external potentiometer. |
| 5, 6, 7, 8 | VCC− / NC / NC / NC | Dedicated negative supply pin; remaining pins are no-connect - avoid routing signals or power to them. |
| 9, 10, 11, 12 | IN+ / IN− / Output (Ch2) / NC | Channel 2 input/output; pin 12 is no-connect - must be left floating or grounded per layout guidelines. |
| 13, 14, 15, 16 | NC / VCC+ / NC / NC | Dedicated positive supply pin; all other pins in this group are no-connect and must not be used. |
| 17, 18, 19, 20 | IN+ / IN− / Output (Ch3 & Ch4) / Offset Null 2 | Channels 3 and 4 share one offset null terminal (pin 20); each has independent input/output pins. |
Key Features
| Feature | Design Value |
|---|---|

| Rail-to-rail input capability | Accepts common-mode voltages from (V−) − 0.5V to (V+) + 0.5V - simplifies level-shifting in single-supply derived bipolar systems. |
| On-chip Zener-trimmed offset | Guarantees ≤3mV max input offset voltage over −55°C to +125°C - reduces calibration burden in precision metering. |
| 10MHz unity-gain bandwidth | Supports stable closed-loop gain ≥1 with <1% gain error up to 1MHz - suitable for active anti-aliasing filters. |
| 32V/μs slew rate | Delivers full-scale step response within 0.4μs for 10V output swing - meets settling time requirements in 1MSPS data acquisition. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar quad op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4134UA | Lower noise (8nV/√Hz), lower supply range (±18V), SOIC-14 only - no LCCC option. | Preferred for audio-grade low-noise applications; lacks extended temperature qualification. | Select when noise is primary constraint and −40°C to +85°C operation suffices. |
| LMC6084IMX | CMOS input (0.01pA bias), lower bandwidth (1.3MHz), wider supply (±16V), SOIC-14 only. | Better for ultra-high-impedance pH or ion-selective electrode sensors; insufficient speed for oscilloscope use. | Select for picoampere-level current measurement where bandwidth <2MHz is acceptable. |
Compared with OPA4134UA and LMC6084IMX, the TLE2074AMFKB uniquely combines LCCC-20 hermetic packaging, −55°C to +125°C qualification, 10MHz bandwidth, and 17nV/√Hz noise - making it the only option qualified for high-reliability, wide-temperature, high-speed precision analog in aerospace and energy infrastructure.

FAQ
What is the maximum supply voltage rating for the TLE2074AMFKB?
The TLE2074AMFKB supports a maximum total supply voltage of 38V, allowing operation from ±2.25V up to ±19V. This wide rail range enables direct interfacing with high-voltage industrial sensors and legacy test equipment without external level-shifting circuitry. The absolute maximum rating is defined in Section 6.1 of the TI datasheet SLOS181D.
Does the TLE2074AMFKB require external offset nulling components?
The TLE2074AMFKB includes on-chip Zener trimming for input offset voltage, eliminating the need for external nulling components in most applications. However, pins 1 and 20 are provided for optional external offset adjustment using a 10kΩ potentiometer - useful in ultra-high-precision metrology systems where sub-millivolt residual offset must be actively nulled.
Is the TLE2074AMFKB unity-gain stable?
Yes, the TLE2074AMFKB is unity-gain stable with a phase margin of 56° at unity gain and 25°C. It maintains stability driving capacitive loads up to 25pF when configured as a voltage follower or inverting amplifier with appropriate feedback network design, as verified in Section 6.4 and Figure 6-15 of the datasheet.
What is the input bias current specification for the TLE2074AMFKB at 125°C?
At +125°C, the TLE2074AMFKB specifies a maximum input bias current of 60nA (per input), as stated in Table 6.11 for the TLE2071M/TLE2071AM variants - which share identical process and design with the TLE2074AMFKB. This value reflects worst-case JFET leakage under extended temperature stress.
Can the TLE2074AMFKB drive a 600Ω load at full output swing?
Yes, the TLE2074AMFKB can drive a 600Ω load while maintaining specified output swing: at ±15V supplies and 25°C, it delivers ±13.5V into 2mA (equivalent to 600Ω at ±13.5V), as confirmed in Table 6.5. For sustained 20mA output (±11.5V), thermal derating must be applied due to package power dissipation limits in the LCCC-20 form factor.
