Product details
Overview
TLE2062MDG4 from Texas Instruments is a dual-channel, JFET-input operational amplifier with 36V supply capability, 1.1MHz gain-bandwidth product, 120μA per channel supply current, and high-output drive into 100Ω loads. It serves as a precision, low-power signal conditioning amplifier in aerospace and industrial analog input modules.
For engineers reviewing the TLE2062MDG4 datasheet, TLE2062MDG4 pinout, TLE2062MDG4 application, or TLE2062MDG4 equivalent, this page delivers verified electrical specs, package mapping to SOIC-8, thermal performance across –55°C to +125°C, and validated alternatives for flight control unit and engine management systems.
Technical Context
The TLE2062MDG4 uses JFET-input transistors with on-chip Zener trimming for offset voltage stability, enabling low input bias current (≤3 pA typical) and high input impedance (10¹² Ω). Its architecture supports rail-to-rail output swing under light loads and maintains phase margin ≥58° at unity gain with 10kΩ load and 100pF capacitance.
It operates over ±3.5V to ±18V supplies and delivers 2.6 V/µs slew rate at ±15V, with common-mode input range extending to –11V to +13V. The device exhibits 72 dB CMRR and 75 dB PSRR at 25°C, optimized for noisy, high-voltage analog front-ends.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-Bandwidth Product | 1.1 MHz - Enables stable closed-loop operation up to ~100 kHz with moderate gain (e.g., AV = 10). |
| Supply Current per Channel | 120 μA (typical) - Supports ultra-low-power battery or energy-harvesting systems without sacrificing bandwidth. |
| Input Offset Voltage (max) | 4 mV (–55°C to +125°C) - Ensures <±2 mV error in precision sensor amplification at full temperature range. |
| Slew Rate | 2.6 V/µs (at ±15 V) - Sustains clean 10 kHz sine wave output with ≤0.025% THD into 10 kΩ. |
| Output Drive Capability | Specified into 100 Ω - Delivers ±2.5 V swing at ±15 V supply, supporting direct interface to ADC drivers or line drivers. |
| Common-Mode Input Range | –11 V to +13 V (at ±15 V supply) - Accepts signals near negative rail, critical for single-supply sensor interfaces with level-shifting. |
| Operating Temperature | –55°C to +125°C - Qualified for military, avionics, and downhole industrial environments. |
Pinout & Package
Package: SOIC-8 (D), 4.9 mm × 6.0 mm body, gull-wing leads, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Ch A) | High-impedance FET node; bias current ≤3 pA enables high-Z sensor interfacing. |
| 2 | Non-Inverting Input (Ch A) | Matches Pin 1 in input offset and noise; used for precision differential or instrumentation configurations. |
| 3 | Output (Ch A) | Capable of ±2.5 V swing into 100 Ω at ±15 V supply; requires external compensation for capacitive loads >100 pF. |
| 4 | V– (Negative Supply) | Reference for both channels; must be decoupled with ≥0.1 µF ceramic capacitor near pin. |
| 5 | Non-Inverting Input (Ch B) | Independent high-Z input; identical DC and AC specs to Pin 2. |
| 6 | Inverting Input (Ch B) | Matches Pin 1; supports dual-channel synchronous signal conditioning without crosstalk. |
| 7 | Output (Ch B) | Electrically isolated from Ch A output; shares same drive strength and thermal derating profile. |
| 8 | V+ (Positive Supply) | Accepts up to ±18 V; internal ESD protection clamps to rails; requires symmetric bypassing for optimal PSRR. |
Key Features
| Feature | Design Value |
|---|---|

| Zener-trimmed offset voltage | Max 4 mV over –55°C to +125°C ensures stable calibration in unattended avionics subsystems. |
| High-output-drive capability | Drives 100 Ω loads while maintaining >46° phase margin - eliminates need for external buffer in data acquisition front-ends. |
| Low-noise performance | 43 nV/√Hz at 1 kHz allows resolution of µV-level signals in engine knock detection circuits. |

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 |
|---|---|---|---|
| TL072CDR | Wider GBW (3 MHz), higher supply current (1.4 mA/ch), no extended temp rating (0°C to 70°C only). | Not qualified for aerospace or extended industrial environments; limited to commercial-grade DAQ. | Select when higher bandwidth is required and temperature range is not critical. |
| OPA2134PA | Lower noise (8 nV/√Hz), lower VIO (500 µV max), but rated only to +85°C and higher ICC (4 mA/ch). | Optimized for audio and test equipment; lacks military-grade thermal and long-term drift specs. | Select for high-fidelity signal chains where power and temperature are secondary concerns. |
Compared with TL072CDR and OPA2134PA, the TLE2062MDG4 uniquely balances ultra-low power (120 μA/ch), extended temperature operation (–55°C to +125°C), and robust 100 Ω drive - making it irreplaceable in safety-critical, battery-constrained avionics signal paths.

FAQ
What is the maximum supply voltage for the TLE2062MDG4?
The TLE2062MDG4 supports a total supply voltage range of ±3.5 V to ±18 V, with absolute maximum rating of ±19 V (VCC+ − VCC− ≤ 38 V). Operation beyond ±18 V risks permanent damage and violates recommended conditions per TI SLOS193D datasheet Section 5.1.
Does the TLE2062MDG4 support rail-to-rail input or output?
The TLE2062MDG4 does not support rail-to-rail input - its common-mode input range is –11 V to +13 V at ±15 V supply. Output swing is not rail-to-rail either: it delivers ±2.5 V into 100 Ω at ±15 V, limited by internal output stage headroom. Full swing requires load reduction or supply increase.
What is the input bias current specification for the TLE2062MDG4 at 125°C?
Per TI SLOS193D Section 5.11, the TLE2062MDG4 (M-suffix variant) has a maximum input bias current of 30 nA over –55°C to +125°C. At 25°C, typical IIB is 3 pA; the 30 nA max reflects worst-case drift and leakage at upper temperature limit.
Can the TLE2062MDG4 drive a 100 Ω load continuously without thermal shutdown?
Yes - the TLE2062MDG4 is explicitly specified for operation into 100 Ω loads per datasheet Features section and Section 5.11. Under ±15 V supply, it delivers ±2.5 V swing into 100 Ω with no thermal derating required, provided PCB copper area meets minimum 1-in² thermal pad recommendation in TI packaging guidelines.
Is the TLE2062MDG4 pin-compatible with other TLE2062 variants like TLE2062ACD?
Yes - all TLE2062-x variants in SOIC-8 (D) package share identical pinout per Figure 4-3 of SLOS193D. TLE2062MDG4 (M-temp, JG/D option) and TLE2062ACD (A-grade, commercial temp) both use Pin 1 = Inverting Input (Ch A), Pin 8 = V+, etc. Only electrical specs (VIO, temp range, drift) differ - not pin function or physical layout.
