Product details
Overview
TLE2062ACDG4 from Texas Instruments is a dual FET-input operational amplifier optimized for high-output-drive, low-power, and wide-bandwidth applications in precision analog signal conditioning. It delivers 1.1 MHz gain-bandwidth product, 120 μA per channel supply current (typical), ±18 V max supply voltage, and specified output drive into 100 Ω loads - enabling use in engine control sensor interfaces and flight control analog input modules.
For engineers reviewing the TLE2062ACDG4 datasheet, TLE2062ACDG4 pinout, TLE2062ACDG4 application, or TLE2062ACDG4 equivalent, key selection criteria include its JFET-input architecture for ultra-low input bias current (<10 pA), rail-to-rail output swing capability under load, low 1/f noise floor, and SOIC-8 packaging compatible with industrial temperature range (–40°C to +85°C).
Technical Context
The TLE2062ACDG4 implements a JFET-input differential pair with on-chip Zener trimming for offset voltage stability, supporting precision DC-coupled amplification across ±3.5 V to ±18 V supplies. Its unity-gain stable design features 46° phase margin at 10 kΩ/100 pF load and delivers 2.2 V/μs slew rate (±5 V) and 2.6 V/μs (±15 V).
It achieves 72–90 dB common-mode rejection ratio and 75–135 dB supply-voltage rejection ratio over temperature, with input resistance >1012 Ω and input capacitance of 4 pF - making it suitable for high-impedance source buffering and low-noise transducer signal conditioning where leakage and capacitive loading must be minimized.
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) without compensation. |
| Supply Current per Channel | 120 μA (typical) - supports battery-powered or energy-constrained systems requiring microamp-level quiescent draw. |
| Input Bias Current | ±10 pA (max, 25°C) - preserves signal integrity when interfacing with high-impedance sensors (e.g., piezoelectric, pH electrodes). |
| Output Drive Capability | Specified into 100 Ω - delivers full-swing output even under heavy resistive loads, critical for driving ADC reference buffers or actuator drivers. |
| Common-Mode Input Range | –11 V to +13 V (at ±15 V supply) - accommodates signals near negative rail, simplifying single-supply or bipolar front-end design. |
| Input Offset Voltage | 2 mV (max, TLE2062A grade) - ensures <0.1% error in 2 V full-scale measurement paths without trimming. |
| Operating Temperature Range | –40°C to +85°C - qualified for automotive engine bay and avionics environmental conditions. |
Pinout & Package
Package: SOIC-8 (D package), 4.9 mm × 6.0 mm body, surface-mount, gull-wing leads.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting Input (Channel A) | Differential input node for first op-amp; high-impedance JFET gate connection. |
| 2 | Non-Inverting Input (Channel A) | Differential input node for first op-amp; accepts high-Z sensor or reference signals. |
| 3 | Output (Channel A) | Class-AB output stage capable of sourcing/sinking >10 mA into 100 Ω while maintaining linearity. |
| 4 | V– (Negative Supply) | Power rail return for both amplifiers; must be decoupled locally to minimize PSRR degradation. |
| 5 | Non-Inverting Input (Channel B) | Second independent input; electrically isolated from Channel A except shared supply rails. |
| 6 | Inverting Input (Channel B) | Second differential input; identical electrical characteristics to Pin 1. |
| 7 | Output (Channel B) | Independent output stage; supports dual-channel signal processing without crosstalk (typical isolation >80 dB). |
| 8 | V+ (Positive Supply) | Power rail input for both amplifiers; requires 0.1 μF ceramic decoupling adjacent to pin. |
Key Features
| Feature | Design Value |
|---|---|
| FET-input architecture | Enables sub-10 pA input bias current, preserving accuracy in high-source-impedance circuits (e.g., photodiode transimpedance amps). |
| High-output-drive capability | Guaranteed performance into 100 Ω loads supports direct interface to transmission lines, DAC buffers, and low-impedance ADC inputs. |
| Low 1/f noise floor | 59 nV/√Hz @ 10 Hz reduces drift-induced errors in DC-coupled instrumentation and precision sensor front-ends. |
| Zener-trimmed offset voltage | 2 mV max (TLE2062A grade) provides factory-calibrated DC accuracy without external trimming components. |
| Wide supply range | ±3.5 V to ±18 V operation allows reuse across 5 V, ±12 V, and ±15 V legacy industrial systems without redesign. |

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 |
|---|---|---|---|
| TLE2062IDR | Same SOIC-8 package and pinout; wider operating temperature (–40°C to +85°C vs. TLE2062ACDG4's same range), but higher 4 mV max VIO (vs. 2 mV for A-grade). | Suitable for cost-sensitive industrial monitoring where ±0.1% gain error is acceptable. | Select when offset voltage tolerance can be relaxed to reduce BOM cost; verify long-term drift in 10+ year deployments. |
| TL072CDR | SOIC-8, JFET-input, but lower 3 mV max VIO, no Zener trimming, and 100 μA supply current - lacks guaranteed 100 Ω drive spec. | Applicable in general-purpose audio and non-critical signal paths where output loading is light. | Choose only if output load remains >10 kΩ; avoid in engine control or flight systems requiring validated heavy-load performance. |
Compared with TLE2062IDR and TL072CDR, the TLE2062ACDG4 provides tighter initial offset (2 mV), guaranteed output drive into 100 Ω, and superior PSRR (135 dB) - making it the preferred choice for safety-critical analog signal chains where parametric consistency and load resilience are mandatory.

FAQ
What is the maximum supply voltage rating for the TLE2062ACDG4?
The TLE2062ACDG4 has an absolute maximum supply voltage rating of ±38 V (VCC+ − VCC−), with recommended operating range of ±3.5 V to ±18 V. Operation beyond ±18 V risks exceeding safe internal junction temperatures and degrading long-term reliability, even if within absolute limits. Always observe derating curves in the datasheet for elevated ambient temperatures.
Does the TLE2062ACDG4 support rail-to-rail input or output operation?
The TLE2062ACDG4 does not provide rail-to-rail input operation - its common-mode input range extends to within ~1.6 V of the negative rail and ~2 V of the positive rail at ±5 V supply. However, its output swings to within ~1.1 V of each rail under 10 kΩ load, and further with lighter loads. For true rail-to-rail performance, consider newer TI families like OPAx320.
How does the TLE2062ACDG4 compare to the TL072 in terms of noise performance?
The TLE2062ACDG4 offers lower 1/f noise: 59 nV/√Hz at 10 Hz versus ~75 nV/√Hz for the TL072. At 1 kHz, both exhibit ~43 nV/√Hz. This makes the TLE2062ACDG4 preferable in DC-coupled, low-frequency sensor applications (e.g., strain gauge bridges) where 0.1–10 Hz noise dominates total integrated error.
Is the TLE2062ACDG4 pin-compatible with other TLE2062 variants in SOIC-8 packages?
Yes - all TLE2062x variants in SOIC-8 (D) package, including TLE2062CDG4, TLE2062IDR, and TLE2062ACDG4, share identical pinout, footprint, and solder profile. Differences lie solely in electrical grading (VIO, temperature range) and marking; no PCB redesign is needed when upgrading from C- or I-grade to A-grade.
What is the typical input capacitance of the TLE2062ACDG4, and how does it affect high-frequency stability?
The TLE2062ACDG4 has a typical input capacitance of 4 pF per input. When combined with source impedances >10 kΩ, this forms a pole that may degrade phase margin - especially in unity-gain follower configurations. For stability-critical designs, add a small series resistor (e.g., 10–50 Ω) at the inverting input or use feedback capacitor compensation per Figure 6-3 in the datasheet.
