Product details
Overview
TL062ACDRE4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-power, high-input-impedance signal conditioning in cost-sensitive industrial and consumer systems. It delivers 200 µA per amplifier supply current, 3.5 V/µs slew rate, ±11 V common-mode input range (including VCC+), and 1 MHz unity-gain bandwidth - enabling precision DC-coupled amplification in battery-powered tablets and white goods.
For engineers reviewing the TL062ACDRE4 datasheet, TL062ACDRE4 pinout, TL062ACDRE4 application, or TL062ACDRE4 equivalent, key selection criteria include ultra-low quiescent current, JFET-input bias current below 200 pA at 25°C, rail-to-rail common-mode capability, and SOIC-8 packaging compatible with automated SMT assembly.
Technical Context
The TL062ACDRE4 implements a two-stage JFET-input architecture with internal frequency compensation, delivering stable unity-gain operation without external components. Its high-impedance differential pair enables <10 pA input offset current and >1 TΩ input resistance, supporting sensor interfacing where leakage must be minimized.
Designed as a lower-power counterpart to the TL072 and TL082 families, it maintains comparable AC performance (1 MHz GBW, 3.5 V/µs slew) while reducing supply current by ~50%. The device operates across 0°C to 70°C (Commercial grade) and supports dual ±15 V or single +30 V supplies.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200 µA per amplifier - enables multi-channel analog front-ends in energy-constrained devices like portable electronics. |
| Input Bias Current | ≤200 pA at 25°C - preserves signal integrity when amplifying high-impedance sources (e.g., piezoelectric sensors). |
| Slew Rate | 3.5 V/µs typical - supports accurate reproduction of audio-band signals and fast-settling control loops. |
| Unity-Gain Bandwidth | 1 MHz - allows stable closed-loop gain configurations up to 10× at 100 kHz without phase margin loss. |
| Common-Mode Range | Includes VCC+ - permits direct sensing of signals referenced to positive rail (e.g., high-side current monitoring). |
| ESD Rating | 1.5 kV HBM - provides robustness against handling damage during PCB assembly and field service. |
| Input Offset Voltage | 6 mV max over temperature - ensures ≤12 mV total error in dual-supply ±15 V systems without trimming. |
Pinout & Package
TL062ACDRE4 is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package measuring 4.90 mm × 6.00 mm, with standard 1.27 mm pitch and gull-wing leads suitable for reflow soldering.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives loads ≥10 kΩ; short-circuit protected to ground or either supply rail. |
| 2 | IN– A | Inverting input for Amplifier A - high-impedance JFET node; sensitive to EMI without proper guarding. |
| 3 | IN+ A | Non-inverting input for Amplifier A - accepts common-mode voltages up to VCC+. |
| 4 | VCC– | Negative supply terminal - must be connected to system ground or negative rail; decoupling capacitor required. |
| 5 | IN+ B | Non-inverting input for Amplifier B - electrically isolated from Amplifier A; crosstalk attenuation ≥120 dB. |
| 6 | IN– B | Inverting input for Amplifier B - shares same JFET process as Pin 2; matched offset characteristics. |
| 7 | VCC+ | Positive supply terminal - supports ±5 V to ±15 V operation; requires local 0.1 µF ceramic decoupling. |
| 8 | OUT B | Amplifier B output - independent drive capability; no internal connection to OUT A. |
Key Features
| Feature | Design Value |
|---|---|
| JFET-input stage | Input impedance >1012 Ω enables microamp-level current measurement without loading transducers. |
| Output short-circuit protection | Allows indefinite shorting to VCC+, VCC–, or GND without latch-up or permanent damage. |
| Internal frequency compensation | Guarantees stability in unity-gain follower and inverting configurations without external compensation networks. |
| Latch-up-free operation | Prevents destructive parasitic thyristor conduction during overvoltage or ESD events. |
| Wide common-mode range | Accepts inputs up to VCC+, simplifying single-supply sensor interface designs without level-shifting circuitry. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET-input operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL062CDR | Same SOIC-8 package and pinout; wider input offset voltage spec (3–15 mV vs. 3–6 mV for TL062ACDRE4). | Acceptable where tighter offset is not required; lower cost in high-volume production. | Select TL062CDR when offset voltage tolerance >6 mV is acceptable and cost optimization is prioritized. |
| TL072CDR | Higher supply current (1.4 mA vs. 0.2 mA); 13 V/µs slew rate; improved noise (18 nV/√Hz vs. 30 nV/√Hz). | Better suited for high-fidelity audio or wideband applications where power budget allows. | Choose TL072CDR only if higher speed and lower noise justify 7× higher quiescent current and thermal load. |
Compared with TL062CDR, TL062ACDRE4 offers tighter input offset voltage control for precision DC amplification; compared with TL072CDR, it reduces supply current by 86% at the expense of bandwidth and noise performance - making it optimal for always-on, battery-operated sensor nodes.

FAQ
What is the maximum supply voltage rating for TL062ACDRE4?
The absolute maximum supply voltage for TL062ACDRE4 is ±18 V (36 V total), but recommended operating conditions specify ±5 V to ±15 V. Exceeding ±15 V may increase power dissipation beyond safe limits and accelerate parameter drift over time. Always observe derating curves in the thermal section of the datasheet when operating near maximum ratings.
Does TL062ACDRE4 require external compensation capacitors?
No, TL062ACDRE4 features internal frequency compensation and is stable in unity-gain configurations without external components. This eliminates layout complexity and component cost in standard inverting, non-inverting, and voltage-follower circuits - verified across all recommended operating conditions including full temperature and supply ranges.
How does the input offset voltage of TL062ACDRE4 compare to TL062CDR?
TL062ACDRE4 guarantees a maximum input offset voltage of 6 mV over temperature (0°C to 70°C), whereas TL062CDR specifies up to 15 mV. This tighter specification makes TL062ACDRE4 preferable in precision DC-coupled applications such as sensor signal conditioning where offset-induced errors must remain below 12 mV in ±15 V systems.
Can TL062ACDRE4 operate from a single supply?
Yes, TL062ACDRE4 supports single-supply operation up to +30 V. Its common-mode input range extends to VCC+, allowing direct interfacing with signals referenced to the positive rail. However, output swing is limited to approximately ±10 V under load, so proper headroom must be maintained for intended signal amplitude and load impedance.
What is the thermal resistance (RθJA) of TL062ACDRE4 in SOIC-8 package?
The junction-to-ambient thermal resistance (RθJA) for TL062ACDRE4 in its SOIC-8 (D) package is 97°C/W under standard JEDEC test conditions. This value assumes a 1-inch² copper pad on the PCB with 2 oz copper; actual thermal performance improves with enhanced heatsinking or multiple thermal vias beneath the exposed pad area.
