Product details
Overview
TL062ACDT from STMicroelectronics is a low-power JFET-input dual operational amplifier in SO-8 package, delivering 3.5 V/µs slew rate, 1 MHz gain-bandwidth product, and 200 µA supply current per amplifier at ±15 V. It features high input impedance (10¹² Ω), rail-to-rail common-mode range (±11.5 V to ±15 V), and output short-circuit protection - used in precision signal conditioning for industrial sensor interfaces and audio preamplifier stages.
For engineers reviewing the TL062ACDT datasheet, TL062ACDT pinout, TL062ACDT application, or TL062ACDT equivalent, key selection criteria include input bias current (≤200 pA typ), offset voltage (3–7.5 mV max), channel separation (120 dB), thermal resistance (125 °C/W for SO-8), and SO-8 footprint compatibility with legacy TL062 variants.
Technical Context
The TL062ACDT integrates matched high-voltage JFET and bipolar transistors on a monolithic die, enabling low-noise, low-drift operation across its full temperature range (0 to +70 °C). Its internal frequency compensation ensures unity-gain stability without external components.
Designed for single-supply or split-supply configurations (±3 V to ±18 V), it supports wide common-mode input (up to VCC±) and differential input (±30 V), with latch-up-free operation and ESD robustness (900 V HBM, 1.5 kV CDM).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200–250 µA per amplifier - enables battery-powered instrumentation with multi-year runtime |
| Slew Rate | 3.5 V/µs - supports 100 kHz small-signal amplification with <1% distortion |
| Gain-Bandwidth Product | 1 MHz - sets usable closed-loop bandwidth up to ~10 kHz at gain = 100 |
| Input Offset Voltage | 3–7.5 mV (max over temp) - defines DC error floor in precision transducer amplifiers |
| Common-Mode Range | ±11.5 V to ±15 V - allows direct interfacing with ±12 V sensors without level-shifting |
| Input Bias Current | 30–200 pA (typ) - preserves signal integrity in high-impedance pH or photodiode circuits |
| Channel Separation | 120 dB - prevents crosstalk between dual-channel audio or differential sensor paths |
Pinout & Package
TL062ACDT is housed in an SO-8 (small outline integrated circuit) plastic micropackage, 4.8–5.0 mm × 5.8–6.2 mm body, 1.27 mm pitch, with gull-wing leads and 125 °C/W junction-to-ambient thermal resistance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Amplified output of first op-amp channel; drives loads ≥10 kΩ |
| 2 | Inverting Input 1 | Negative feedback node for Channel 1; accepts signals within Vicm range |
| 3 | Non-inverting Input 1 | Positive input for Channel 1; high-impedance (10¹² Ω) sensing node |
| 4 | VCC− | Negative supply rail connection; must be decoupled with 100 nF ceramic capacitor |
| 5 | Non-inverting Input 2 | Positive input for Channel 2; electrically isolated from Channel 1 inputs |
| 6 | Inverting Input 2 | Negative feedback node for Channel 2; shares no internal coupling with Pin 2 |
| 7 | Output 2 | Amplified output of second op-amp channel; independent output drive capability |
| 8 | VCC+ | Positive supply rail connection; referenced to Pin 4 for symmetric ±V operation |
Key Features
| Feature | Design Value |
|---|---|
| JFET input stage | 10¹² Ω input resistance and ≤200 pA bias current enable ultra-high-Z sensor interfacing |
| Internal frequency compensation | Guarantees stable unity-gain operation without external compensation capacitors |
| Output short-circuit protection | Allows indefinite shorting to either rail or ground without damage under normal ambient conditions |
| Latch-up free design | Prevents destructive parasitic thyristor conduction during overvoltage or ESD events |

Applications
| Industrial Sensor Signal Conditioning | Audio Pre-amplifier Stage |
|---|---|
|
Use Scenario: Amplifying low-level mV outputs from RTD, thermocouple, or strain gauge bridges in PLC analog input modules. IC Role / Device Role / Timing Role: Dual-channel DC-coupled instrumentation amplifier front-end with matched gain paths. Use Value: 120 dB channel separation prevents cross-talk between adjacent sensor channels; 3.5 V/µs slew rate preserves step response fidelity in 10 Hz–1 kHz measurement bands. |
Use Scenario: First-stage gain block for electret microphone or line-level audio in consumer audio mixers and voice recorders. IC Role / Device Role / Timing Role: Low-noise, low-distortion dual op-amp providing 20–40 dB gain before ADC or tone control stage. Use Value: 42 nV/√Hz input noise and 1 MHz GBW support clean 20 kHz bandwidth; SO-8 footprint simplifies layout in space-constrained PCBs. |
| Quadrature Oscillator | DC Motor Speed Reference Generator |
|
Use Scenario: Generating synchronized sine/cosine waveforms for resolver simulation or phase-locked loop reference in motion control systems. IC Role / Device Role / Timing Role: Dual op-amp configured as coupled integrator pair in 100 kHz oscillator topology (per Figure 19). Use Value: Matched slew rate and gain-bandwidth ensure quadrature accuracy (<1° phase error); low power enables integration into embedded controller boards. |
Use Scenario: Converting PWM duty cycle or potentiometer wiper position into stable analog speed reference voltage for BLDC motor drivers. IC Role / Device Role / Timing Role: Dual op-amp used as active low-pass filter + buffer to smooth and scale control signals. Use Value: Rail-to-rail common-mode input accepts 0–5 V PWM-derived signals; 200 µA quiescent current minimizes standby power in always-on motor controllers. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDT | Lower input noise (18 nV/√Hz vs. 42 nV/√Hz), higher slew rate (13 V/µs), but 1.4 mA supply current | Better for audio; unsuitable for battery-powered sensor nodes due to 7× higher ICC | Select when SNR > power efficiency; verify SO-8 thermal derating at 1.4 mA |
| RC4558DT | Bipolar input (higher Iib = 500 nA), lower Vio (2 mV), no JFET input impedance advantage | Acceptable for general-purpose AC-coupled amplification where input Z > 1 MΩ suffices | Choose only if cost sensitivity outweighs input bias and noise requirements |
Compared with TL072CDT and RC4558DT, TL062ACDT uniquely balances ultra-low power (200 µA), JFET input impedance (10¹² Ω), and adequate speed (1 MHz GBW) - making it optimal for always-on, high-impedance sensor front-ends where thermal and battery constraints rule out higher-ICC alternatives.

FAQ
What is the maximum operating supply voltage for TL062ACDT?
The absolute maximum supply voltage is ±18 V (36 V total), but the recommended operating range is ±3 V to ±18 V per Table 2. Operation at ±18 V requires thermal derating due to 680 mW power dissipation limit and 125 °C/W RthJA; sustained use above ±15 V should include board-level thermal analysis.
Does TL062ACDT support single-supply operation?
Yes - it operates with VCC+ = +5 V to +36 V and VCC− = 0 V (ground), provided input common-mode and output swing remain within specified limits. For example, with +12 V/0 V supply, Vicm spans 0 V to +10.5 V and Vopp reaches up to +10.5 V (RL = 10 kΩ), confirmed in Figures 2–4.
How does TL062ACDT differ from TL062CDT?
TL062ACDT is the "A" grade variant: it specifies tighter input offset voltage (3–7.5 mV vs. 3–20 mV for TL062CDT) and lower input offset current (5–100 pA vs. 5–200 pA) across 0 to +70 °C. Both share identical SO-8 packaging, pinout, and electrical architecture - TL062ACDT is selected when higher DC precision is required.
Is TL062ACDT RoHS-compliant and halogen-free?
Yes - TL062ACDT is manufactured in ST's ECOPACK®-compliant SO-8 package, meeting RoHS Directive 2011/65/EU and halogen-free requirements per IEC 61249-2-21. The "DT" suffix denotes tape-and-reel packaging compatible with automated SMT assembly.
