Product details
Overview
TLE2061MFKB from Texas Instruments is a single-channel, JFET-input operational amplifier with high-output-drive capability and ultra-low supply current (120 μA typical). It operates over ±3.5 V to ±18 V supply rails, delivers ±4.9 V output swing into 10 kΩ at ±5 V, and features 1.1 MHz gain-bandwidth product and 4 V/µs slew rate. It is used in precision analog signal conditioning within flight control units and full-authority digital engine control systems.
For engineers reviewing the TLE2061MFKB datasheet, TLE2061MFKB pinout, TLE2061MFKB application, or TLE2061MFKB equivalent, this page provides verified electrical specifications, LCCC-20 package terminal mapping, military-grade temperature range (–55°C to +125°C), and validated alternatives for high-reliability aerospace and industrial instrumentation designs.
Technical Context
The TLE2061MFKB uses a JFET-input stage with on-chip Zener trimming for offset voltage calibration, enabling low input bias current (3 pA typical) and high input resistance (1 TΩ). Its architecture supports stable unity-gain operation with 58° phase margin into 10 kΩ//100 pF loads.
It is specified for high-output-drive performance into low-impedance loads (e.g., 600 Ω), with guaranteed output swing of ±2.5 V under those conditions. The device maintains DC precision across its full military temperature range, with input offset voltage drift of only 1 μV/°C and long-term drift of 0.04 μV/month.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±3.5 V to ±18 V - Supports dual-rail operation in wide-input industrial and avionics power domains. |
| Gain-Bandwidth Product | 1.1 MHz - Enables stable closed-loop gain up to ~10× at audio and low-speed control frequencies. |
| Slew Rate | 4 V/µs - Sustains clean 10 kHz sine-wave output with ≤0.025% THD into 10 kΩ. |
| Input Offset Voltage (max) | 3.1 mV at 25°C (TLE2061AM variant) - Matches precision sensor front-end requirements without external trimming. |
| Supply Current (typ) | 120 μA per channel - Enables multi-channel battery-powered instrumentation with minimal quiescent load. |
| Input Bias Current (typ) | 3 pA - Minimizes voltage error across high-impedance source networks (e.g., piezoelectric sensors). |
| Output Drive Capability | ±2.5 V into 600 Ω - Directly interfaces with legacy analog I/O standards and low-Z actuator drivers. |
Pinout & Package
LCCC-20 (FK) ceramic leadless chip carrier package: 8.89 mm × 8.89 mm body, hermetically sealed, suitable for high-reliability military and aerospace applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | V– (Negative Supply) | Return path for negative rail; must be decoupled locally to minimize noise coupling into high-Z inputs. |
| 2 | Inverting Input (–) | Differential input node; high impedance (1 TΩ) and low bias current (3 pA) enable precision transimpedance configurations. |
| 3 | Non-Inverting Input (+) | Reference input node; matched common-mode range (–1.6 V to +4 V at ±5 V supplies) ensures rail-to-rail input operation. |
| 4 | Output | Class-AB output stage capable of sourcing/sinking >10 mA into 600 Ω while maintaining linearity. |
| 5–8, 13–20 | No Connect (NC) | Unused terminals; electrically isolated and not bonded - must remain unconnected per TI design. |
| 9 | V+ (Positive Supply) | Primary positive rail connection; requires local 0.1 μF ceramic decoupling adjacent to pin. |
| 10–12 | No Connect (NC) | Structural pads only; no internal connection - no routing or thermal relief required. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables picoampere-level input bias current (3 pA typ), critical for high-source-impedance sensor interfacing. |
| Zener-trimmed offset voltage | Guarantees ≤3.1 mV max VIO at 25°C (TLE2061AM variant), reducing need for external nulling circuitry. |
| Military temperature range | Specified from –55°C to +125°C, supporting deployment in engine bays, flight control surfaces, and space-qualified subsystems. |
| High-output-drive capability | Delivers ±2.5 V into 600 Ω, eliminating external buffer stages in analog output modules and DAC reconstruction paths. |
| Low-noise performance | 43 nV/√Hz input voltage noise at 1 kHz enables use in low-level signal amplification without added gain-stage noise penalty. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277UA | Lower input offset voltage (10 μV max), higher supply current (700 μA), SOIC-8 only. | Optimized for lab-grade instrumentation; lacks military temp rating and high-output-drive into 600 Ω. | Select when sub-25 μV offset dominates over power and drive requirements. |
| LMC6061IM | CMOS input (0.01 pA bias), wider supply range (2.7–15.5 V single), but lower GBW (1.4 MHz) and no ±18 V support. | Targeted at low-voltage portable systems; not rated for –55°C or high-voltage bipolar rails. | Select for battery-powered sensor nodes requiring femtoampere bias, not for avionics or industrial 36 V systems. |
Compared with OPA277UA and LMC6061IM, the TLE2061MFKB uniquely combines military temperature range, ±18 V operation, 600 Ω drive capability, and 3 pA input bias-making it irreplaceable in high-reliability analog signal chains where all four attributes are simultaneously required.

The TLE2061MFKB is rated for operation from –55°C to +125°C, meeting MIL-PRF-38535 requirements for high-reliability military and aerospace applications. This range is confirmed in Section 5.11 of the TI datasheet (SLOS193D), where all electrical characteristics are specified across this full temperature span.
Does the TLE2061MFKB support ±15 V operation?
Yes, the TLE2061MFKB supports ±15 V operation per the Recommended Operating Conditions table (Section 5.2), with guaranteed performance including ±13.2 V output swing into 10 kΩ and 2.6 V/µs slew rate. All key parameters-including CMRR, kSVR, and ICC-are characterized at ±15 V in Sections 5.13 and 5.14.
What is the input bias current specification for the TLE2061MFKB?
The TLE2061MFKB has a typical input bias current of 3 pA at 25°C, with a maximum of 30 nA across –55°C to +125°C (Section 5.11). This ultra-low value stems from its JFET-input architecture and enables accurate amplification of signals from high-impedance sources like piezoelectric sensors and pH electrodes.
Is the TLE2061MFKB pin-compatible with other TLE206x variants in LCCC-20?
Yes-the TLE2061MFKB shares identical pinout and footprint with all TLE2061xM variants in FK (LCCC-20) packaging, including TLE2061AMFK and TLE2061BMFK. Figure 4-5 in the datasheet confirms identical top-view pin assignments, and all share the same NC pin configuration and supply/output terminal locations.
What load impedance can the TLE2061MFKB drive while maintaining specified performance?
The TLE2061MFKB is explicitly specified to drive 600 Ω loads, delivering ±2.5 V output swing under those conditions (Section 5.11). It also maintains ≥1.1 MHz bandwidth into 10 kΩ and sustains 0.025% THD at 10 kHz into 10 kΩ, confirming robust small-signal and large-signal linearity across common industrial load ranges.
