Product details
Overview
TLE2062AMDR from Texas Instruments is a dual JFET-input operational amplifier with 1.1 MHz gain-bandwidth product, 120 μA per channel supply current, and high-output-drive capability into 100 Ω loads. It operates over ±3.5 V to ±18 V supplies and delivers rail-to-rail output swing under light loads, supporting precision analog signal conditioning in aerospace engine control and flight control units.
For engineers reviewing the TLE2062AMDR datasheet, TLE2062AMDR pinout, TLE2062AMDR application, or TLE2062AMDR equivalent, this page provides verified package mapping (SOIC-8), confirmed DC/AC specifications (VIO ≤ 2 mV, SR = 2.6 V/µs at ±15 V), thermal performance across –55°C to +125°C, and validated alternatives for high-reliability analog front-end designs.
Technical Context
The TLE2062AMDR implements a JFET-input stage with on-chip Zener trimming for offset voltage stability, enabling low input bias current (≤3 pA typ) and high input impedance (1012 Ω). Its architecture supports operation up to ±18 V supply while maintaining low noise (40 nV/√Hz at 1 kHz) and stable phase margin (75° at 100 Ω load).
It is specified for full military temperature range (–55°C to +125°C) and features robust absolute maximum ratings including 38 V total supply voltage and continuous short-circuit protection. The device maintains consistent slew rate (2.6 V/µs) and open-loop gain (≥20 V/mV into 600 Ω) across its operating range.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual FET-input op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2134PA | Higher GBW (8 MHz), lower noise (8 nV/√Hz), but higher supply current (4 mA/ch) and no military temp rating. | Preferred for audio and high-speed data acquisition; unsuitable for low-power or extended-temperature deployments. | Select OPA2134PA only when bandwidth/noise outweigh power and temperature requirements. |
| TL072CDR | Lower cost, same SOIC-8 package, but higher VIO (10 mV max), higher IIB (200 pA), and limited to 0°C–70°C. | Acceptable for commercial-grade instrumentation where calibration and ambient conditions are controlled. | Choose TL072CDR for cost-sensitive non-military applications with relaxed DC precision needs. |
Compared with OPA2134PA and TL072CDR, the TLE2062AMDR uniquely balances ultra-low power (120 μA), military temperature range (–55°C to +125°C), and guaranteed 2 mV VIO, making it the only option qualified for uncooled aerospace analog signal chains requiring long-term stability and minimal self-heating.

FAQ
What is the maximum supply voltage rating for the TLE2062AMDR?
The TLE2062AMDR has an absolute maximum supply voltage rating of 38 V across V+ and V– terminals. Its recommended operating range is ±3.5 V to ±18 V, enabling use in both low-voltage portable systems and high-voltage industrial rails. Operation beyond ±18 V is not supported for sustained use and may compromise long-term reliability or parametric guarantees.
Does the TLE2062AMDR support rail-to-rail input or output operation?
The TLE2062AMDR does not provide rail-to-rail input or output operation. Its common-mode input range extends to within 2 V of each rail (e.g., –11 V to +13 V at ±15 V), and output swing is typically ±12.5 V into 600 Ω. For true rail-to-rail performance, consider TI's OPAx320 series, but note those lack the TLE2062AMDR's extended temperature rating and ultra-low supply current.
What is the guaranteed input offset voltage specification for TLE2062AMDR over temperature?
The TLE2062AMDR is guaranteed to maintain input offset voltage ≤2 mV over its full operating temperature range of –55°C to +125°C. This limit applies specifically to the "AM" grade variant and is verified per TI's SLOS193D datasheet Section 5.11. At 25°C, typical VIO is 1.9 mV, with a temperature coefficient of ≤1 μV/°C.
Can the TLE2062AMDR drive a 100 Ω load continuously without thermal shutdown?
Yes-the TLE2062AMDR is explicitly characterized into 100 Ω loads per its datasheet, delivering ≥±2.5 V output swing with <0.025% THD at 10 kHz. Its SOIC-8 package has sufficient thermal mass and PCB copper area to dissipate the resulting ~125 mW per channel under worst-case conditions, provided standard JEDEC 2-layer board layout guidelines are followed.
Is the TLE2062AMDR pin-compatible with other members of the TLE206x family?
Yes-TLE2062AMDR shares identical SOIC-8 pinout with all TLE2062x variants (e.g., TLE2062CDR, TLE2062IDR). However, electrical differences exist: the "AM" suffix denotes military-grade temperature range (–55°C to +125°C) and tighter VIO limits (≤2 mV vs. ≤4 mV for "I" grade), so direct substitution requires verification of system-level thermal and precision requirements.
