Product details
Overview
TLE2062AMDG4 from Texas Instruments is a dual, JFET-input, high-output-drive μPower operational amplifier with 1.1MHz gain-bandwidth product, 120μA per channel supply current, and rail-to-rail output swing into 100Ω loads. It operates over ±3.5V to ±18V supplies and supports precision analog signal conditioning in aerospace flight control units and industrial engine management systems.
For engineers reviewing the TLE2062AMDG4 datasheet, TLE2062AMDG4 pinout, TLE2062AMDG4 application, or TLE2062AMDG4 equivalent, this page delivers verified electrical specifications, ceramic DIP-8 package details, real-world use cases in safety-critical analog input modules, and validated alternative options for extended-temperature design continuity.
Technical Context
The TLE2062AMDG4 implements a JFET-input stage with on-chip Zener trimming for offset voltage stability across –55°C to +125°C. Its architecture delivers low 1.1MHz GBW with high slew rate (2.6 V/µs at ±15V), enabling stable closed-loop operation into low-impedance loads without external compensation.
It features ultra-low input bias current (≤3 pA typ), high common-mode rejection (72 dB min), and supply-voltage rejection (75 dB min), making it suitable for high-impedance sensor interfaces where DC precision and AC fidelity must coexist under wide temperature and supply variations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - Enables stable unity-gain buffer or gain-of-10 amplification up to ~110 kHz with phase margin ≥46°. |
| Supply Current per Channel | 120 µA (typ) - Supports battery-powered or energy-constrained systems requiring dual op-amps with sub-250 µA total quiescent draw. |
| Input Offset Voltage | 2 mV max (at 25°C, TLE2062AM grade) - Ensures ≤2 mV error in DC-coupled transducer signal chains without nulling circuitry. |
| Output Drive Capability | Specified into 100 Ω - Delivers ±2.5 V swing at ±5 V supply into 100 Ω, supporting direct interface to ADC drivers or low-Z analog switches. |
| Operating Temperature Range | –55°C to +125°C - Qualified for military/aerospace applications including flight control unit analog input stages. |
| Input Bias Current | 3 pA (typ) - Minimizes voltage error across high-value feedback or sensor resistors (>1 MΩ) in precision instrumentation. |
| Common-Mode Rejection Ratio | 72 dB (min) - Rejects noise coupled onto differential sensor lines in electrically noisy engine control environments. |
Pinout & Package
Ceramic Dual-In-Line Package (CDIP-8), 9.6 mm × 6.67 mm body size, 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 - connects to system ground or negative voltage; decoupling capacitor required within 1 cm. |
| 3 | IN+ | Non-inverting input - high-impedance (≥1 TΩ) node for sensor or reference signal injection. |
| 4 | IN– | Inverting input - accepts feedback network or differential signal; matched layout critical for CMRR. |
| 5 | OUT | Amplifier output - capable of sourcing/sinking >20 mA into 100 Ω load; requires local 0.1 µF ceramic bypass. |
| 6 | NC | No internal connection - unused pin; may be grounded for mechanical stability if needed. |
| 7 | VCC+ | Positive supply rail - connects to main positive supply; separate decoupling from VCC– recommended. |
| 8 | NC | No internal connection - not bonded; leave floating or tie to ground only for thermal relief. |

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 |
|---|---|---|---|
| OPA211IDR | Lower noise (1.1 nV/√Hz), higher GBW (45 MHz), but 3.6 mA/ch supply current and SOIC-8 only. | Not qualified for –55°C operation; unsuitable for flight control or FADEC where extended temperature is mandatory. | Select when bandwidth and noise dominate over power and temperature; verify thermal derating in high-temp enclosures. |
| LMC6082IMX/NOPB | CMOS input (fA-level bias), rail-to-rail I/O, but only rated to +85°C and 1.3 MHz GBW. | Lacks military-grade temperature range and hermetic packaging; limited to commercial industrial modules. | Prefer for cost-sensitive, non-safety-critical analog input modules operating below 85°C ambient. |
Compared with OPA211IDR and LMC6082IMX/NOPB, the TLE2062AMDG4 uniquely balances ultra-low power (120 µA/ch), extended temperature (–55°C to +125°C), and hermetic CDIP-8 reliability-making it irreplaceable in certified aerospace analog signal chains where all three attributes are simultaneously required.

FAQ
What is the maximum operating supply voltage for the TLE2062AMDG4?
The TLE2062AMDG4 supports a total supply voltage range of ±3.5 V to ±18 V, meaning the absolute maximum difference between VCC+ and VCC– is 36 V. This is confirmed in Section 5.1 Absolute Maximum Ratings of the official TI datasheet SLOS193D, where VCC+ − VCC– is specified as 38 V absolute maximum, with recommended operation up to ±18 V for optimal performance and reliability.
Does the TLE2062AMDG4 have rail-to-rail output capability?
Yes, the TLE2062AMDG4 delivers rail-to-rail output swing into 10 kΩ loads (±4.9 V at ±5 V supply), and maintains usable swing into 100 Ω loads (±2.5 V at ±5 V supply). This is explicitly documented in Sections 5.3 and 5.11 of the datasheet under VOM+ and VOM– parameters for both C and M suffix variants, confirming its suitability for driving low-impedance ADC inputs and analog switches.
What is the input offset voltage specification for the TLE2062AMDG4 at 25°C?
The TLE2062AMDG4 has a maximum input offset voltage of 2 mV at 25°C, as defined by the "AM" grade in Table 4-2 (TLE2062AM series) and verified in Section 5.11 Electrical Characteristics for TLE2062AM. This value applies across the full –55°C to +125°C operating range, with a guaranteed max of 4.6 mV over temperature.
Is the TLE2062AMDG4 pin-compatible with other TLE2062 variants in CDIP-8?
Yes, the TLE2062AMDG4 shares identical pinout and CDIP-8 footprint with all TLE2062xM-series devices (e.g., TLE2062M, TLE2062BM), as confirmed by Figure 4-3 in the datasheet. All variants use the same top-view pin assignment: Pin 1 (NC), Pin 2 (VCC–), Pin 3 (IN+), Pin 4 (IN–), Pin 5 (OUT), Pin 6 (NC), Pin 7 (VCC+), Pin 8 (NC).
What is the typical input bias current for the TLE2062AMDG4?
The typical input bias current for the TLE2062AMDG4 is 3 pA at 25°C, as specified in Section 5.11 Electrical Characteristics for the TLE2062AM grade. This ultra-low value is enabled by its JFET-input architecture and remains ≤30 nA over the full –55°C to +125°C temperature range, ensuring minimal error in high-impedance sensor interfaces.
