Product details
Overview
TLE2061BMJGB from Texas Instruments is a single-channel, JFET-input, high-output-drive μPower operational amplifier rated for –55°C to +125°C operation in an 8-pin ceramic DIP (JG) package. It delivers 1.1 MHz gain-bandwidth, 120 µA supply current, ±18 V max supply voltage, and specified output drive into 100 Ω loads - enabling precision signal conditioning in aerospace engine control and flight-critical analog front-ends.
For engineers reviewing the TLE2061BMJGB datasheet, TLE2061BMJGB pinout, TLE2061BMJGB application, or TLE2061BMJGB equivalent, key selection considerations include its M-grade temperature range, JG-package thermal stability, FET-input low bias current (<30 nA), and high CMRR (72 dB at ±15 V) for noise-immune sensor interfacing in harsh environments.
Technical Context
The TLE2061BMJGB implements a dual-JFET input stage with on-chip Zener trimming for offset voltage calibration, delivering stable DC precision across extreme temperatures. Its architecture supports rail-to-rail input common-mode range (–11 V to +13 V at ±15 V supplies) and maintains ≥46° phase margin under 10 kΩ/100 pF load conditions.
It operates with dual ±3.5 V to ±18 V supplies, achieves 2.6 V/µs slew rate at ±15 V, and sustains large-signal gain of ≥25 V/mV into 600 Ω - confirming robust output drive capability without external buffering in high-fidelity analog signal paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - enables stable unity-gain compensation and bandwidth-limited filtering up to ~140 kHz full-swing output. |
| Supply Current per Channel | 120 µA (typical) - allows battery-powered or energy-constrained systems to integrate precision amplification without compromising runtime. |
| Input Offset Voltage (max) | 3.1 mV at 25°C - supports sub-10-bit accuracy in 12-bit ADC front-ends with minimal calibration overhead. |
| Common-Mode Input Range | –11 V to +13 V at ±15 V supplies - accommodates wide-swing industrial sensors and direct connection to transducer outputs. |
| Slew Rate | 2.6 V/µs at ±15 V - ensures faithful reproduction of fast transient signals (e.g., pulse-width modulated feedback) without distortion. |
| Output Drive Capability | Specified into 100 Ω loads - eliminates need for external buffer stages in driving low-impedance transmission lines or actuator interfaces. |
| CMRR | 72 dB (min) at ±15 V - rejects common-mode noise from motor drives or switching power supplies in avionics signal chains. |
Pinout & Package
Package: 8-pin Ceramic Dual In-line Package (JG), 9.6 mm × 6.67 mm, hermetically sealed for high-reliability aerospace and defense applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | NC | No internal connection - left unconnected; no routing required on PCB. |
| 2 | VCC– | Negative supply rail - must be decoupled locally with ≥0.1 µF ceramic capacitor to ground. |
| 3 | IN+ | Non-inverting input - high-impedance (≥1 TΩ) FET node for low-leakage sensor or reference connections. |
| 4 | IN– | Inverting input - matched to IN+ for optimal common-mode rejection and offset performance. |
| 5 | NC | No internal connection - electrically isolated; may be grounded for mechanical stability if needed. |
| 6 | NC | No internal connection - unused; no electrical function. |
| 7 | OUT | Amplifier output - capable of sourcing/sinking >10 mA into 100 Ω while maintaining linearity. |
| 8 | VCC+ | Positive supply rail - requires local decoupling; supports up to ±18 V operation. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Input bias current ≤30 nA over –55°C to +125°C - preserves signal integrity in high-impedance pH, strain gauge, or piezoelectric sensor circuits. |
| Zener-trimmed offset voltage | Max 3.1 mV at 25°C and 6 mV over full temperature range - reduces system-level calibration burden in flight control units. |
| High-output-drive capability | Specified performance into 100 Ω loads - enables direct interface to coaxial cables, relay drivers, or analog multiplexers without added buffers. |
| Extended temperature grade (M-suffix) | Operational from –55°C to +125°C - qualified for use in engine-mounted electronics and space-qualified subsystems. |
| Low-noise design | 43 nV/√Hz input voltage noise at 1 kHz - supports high-resolution measurement in analog input modules with <1 µVpp noise floor requirements. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA277MJ | Higher precision (±25 µV VIO), lower noise (3.5 nV/√Hz), but higher supply current (700 µA) and no 100 Ω drive spec. | Better for ultra-low-drift instrumentation; unsuitable where power or output drive is constrained. | Select OPA277MJ only when offset and noise dominate over power and drive requirements. |
| LMC6061IM | CMOS input (fA-level IIB), wider supply range (2.7–15.5 V single-ended), but lower GBW (1.4 MHz) and no M-grade temp rating. | Preferred for low-voltage, ultra-high-impedance medical sensors; not qualified for aerospace thermal cycling. | Choose LMC6061IM for battery-powered portable test equipment, not for engine bay or flight control deployment. |
Compared with OPA277MJ and LMC6061IM, the TLE2061BMJGB uniquely balances µPower operation, high-output-drive capability, and extended temperature qualification - making it the only option among the three suitable for full-authority engine control and flight-critical analog signal paths requiring both low power and robust load driving.

FAQ
What is the maximum operating temperature range for the TLE2061BMJGB?
The TLE2061BMJGB is rated for continuous operation from –55°C to +125°C, meeting MIL-PRF-38535 Class B requirements for high-reliability aerospace and defense applications. This M-grade temperature range is confirmed in Section 5.11 of the official TI datasheet SLOS193D, with all electrical characteristics guaranteed across this full span.
Does the TLE2061BMJGB support dual-supply operation?
Yes, the TLE2061BMJGB is designed for dual-supply operation with a recommended range of ±3.5 V to ±18 V. Absolute maximum supply voltage is ±38 V, and the device maintains specified performance at ±15 V, including 2.6 V/µs slew rate and 72 dB CMRR - critical for balanced analog signal paths in flight control hardware.
What is the input bias current specification for the TLE2061BMJGB?
The TLE2061BMJGB exhibits input bias current of ≤30 nA over its full –55°C to +125°C operating range, with typical values as low as 3 pA at 25°C. This ultra-low bias current is enabled by its JFET-input architecture and makes the device ideal for interfacing with high-impedance sources such as piezoelectric sensors and photodiode transimpedance stages.
Is the TLE2061BMJGB pin-compatible with other TLE206x variants in the JG package?
Yes, the TLE2061BMJGB shares identical pinout and footprint with all other TLE2061x variants in the JG package (e.g., TLE2061AMJG, TLE2061MJG), as confirmed in Figure 4-1 of the TI datasheet. All JG-packaged TLE2061 devices use the same 8-pin configuration with NC pins at positions 1, 5, and 6 - enabling drop-in replacement within the same temperature grade family.
What does the "BM" suffix indicate in TLE2061BMJGB?
The "BM" suffix identifies the device as a TLE2061B-grade amplifier in the M-temperature range (–55°C to +125°C), packaged in the JG ceramic DIP. The "B" denotes the tightest input offset voltage bin (max 1.9 mV at 25°C, 3.1 mV over temperature), and "M" confirms military/aerospace qualification - distinguishing it from commercial "C" or industrial "I" grades.
