Product details

Overview

TL062ACN from STMicroelectronics is a low-power JFET-input dual operational amplifier designed for precision analog signal conditioning in cost-sensitive industrial and consumer systems. It delivers 3.5 V/µs slew rate, ±11.5 V input common-mode range (up to V_CC+), 200 µA supply current per amplifier, and 1 MHz gain-bandwidth product - enabling stable AC-coupled amplification and active filtering in single-supply or split-supply configurations.

For engineers reviewing the TL062ACN datasheet, TL062ACN pinout, TL062ACN application, or TL062ACN equivalent, key selection considerations include its JFET-input high-impedance (10¹² Ω), low input bias current (≤200 nA), output short-circuit protection, and DIP8 package compatibility with legacy through-hole PCB layouts requiring minimal board rework.

Technical Context

The TL062ACN integrates two matched JFET-input op-amps on a single monolithic die, using high-voltage JFETs for input stages and bipolar transistors for output drivers. Its internal frequency compensation ensures unity-gain stability with 10 kΩ load and 100 pF capacitive load, supporting robust operation in sensor interface and audio preamp circuits without external compensation.

It operates across ±6 V to ±18 V supply rails (12–36 V total), supports rail-to-rail input common-mode voltage (±11.5 V at ±15 V supplies), and maintains 120 dB channel separation - critical for dual-channel instrumentation where crosstalk must remain below –100 dB in differential signal paths.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Current	200–250 µA per amplifier - enables battery-powered or energy-constrained designs with dual-channel analog front-ends.
Slew Rate	3.5 V/µs - supports clean 100 kHz sine wave generation and fast transient response in active filters.
Input Bias Current	≤200 nA at +25 °C - preserves signal integrity in high-impedance sensor interfaces (e.g., piezoelectric or pH electrodes).
Input Resistance	10¹² Ω - minimizes loading error when buffering high-Z sources like crystal oscillators or photodiode transimpedance nodes.
Common-Mode Rejection	80–86 dB - suppresses power supply noise and ground bounce in noisy industrial environments.
Output Voltage Swing	±20 V into 10 kΩ - delivers full dynamic range across ±15 V supplies without clipping in line-driver applications.
Gain-Bandwidth Product	1 MHz - sets usable closed-loop bandwidth to ~10 kHz at gain = 100, suitable for anti-aliasing and tone control filters.

Pinout & Package

Dual in-line plastic package (DIP8), 0.3-inch body width, through-hole mounting. Pin 1 marked by notch or dot; top view orientation shown in datasheet Figure 1.

Pin/Terminal	Circuit Role	Design Meaning
1	Output 1	Amplifier 1 output node; capable of sourcing/sinking ≥10 mA with short-circuit protection.
2	Inverting Input 1	Inverting terminal of first op-amp; high-impedance JFET input (10¹² Ω) with ≤200 nA bias current.
3	Non-inverting Input 1	Non-inverting terminal of first op-amp; identical impedance and bias characteristics as Pin 2.
4	V_CC–	Negative supply rail connection; referenced to system ground in single-supply configurations.
5	Non-inverting Input 2	Non-inverting terminal of second op-amp; electrically isolated but thermally coupled to Amp 1 for matched drift.
6	Inverting Input 2	Inverting terminal of second op-amp; shares same process-matched JFET structure as Pins 2 and 3.
7	Output 2	Amplifier 2 output node; independent channel with 120 dB isolation from Output 1 at 100 Hz.
8	V_CC+	Positive supply rail connection; supports up to ±18 V operation with thermal derating above +70 °C.

Key Features

Feature	Design Value
Very low power consumption	200 µA per amplifier - reduces thermal load and extends battery life in portable test equipment.
High input impedance JFET stage	10¹² Ω input resistance - avoids signal attenuation in megohm-range sensor networks.
Output short-circuit protection	Indefinite short to either rail or ground - eliminates need for external current-limiting resistors in driver stages.
Latch-up free operation	Guaranteed under all valid operating conditions - prevents catastrophic failure during power sequencing or ESD events.
Wide common-mode voltage range	±11.5 V at ±15 V supplies - allows direct interfacing to signals near supply rails without level-shifting.

Applications

DC-Coupled Sensor Interface

Use Scenario: Amplifying low-level microphone or piezo pickup signals before ADC sampling in portable audio recorders.

IC Role / Device Role / Timing Role: Dual-channel voltage amplifier with DC-coupled inputs and adjustable gain via external resistors.

Use Value: 42 nV/√Hz input noise and 3.5 V/µs slew rate preserve signal fidelity up to 20 kHz while rejecting 50/60 Hz hum via high CMRR.

Use Scenario: Conditioning output from strain gauge bridges or thermopile sensors in HVAC control modules.

IC Role / Device Role / Timing Role: Instrumentation-grade dual op-amp configured as differential amplifier and reference buffer.

Use Value: Matched input offset drift (10 µV/°C) and 120 dB channel separation minimize thermal-induced measurement errors across temperature cycles.

Active Low-Pass Filter

Quadrature Oscillator

Use Scenario: 2nd-order Sallen-Key filter in medical ECG front-end to attenuate RF interference above 150 Hz.

IC Role / Device Role / Timing Role: Dual op-amp implementing unity-gain buffer and feedback integrator in filter topology.

Use Value: Internal frequency compensation ensures stable 1 MHz GBW operation with 100 pF capacitive loads - eliminating external compensation components.

Equivalent & Alternatives

The following parts are listed as comparable options for similar dual JFET-input op-amp applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TL072CP	Lower input noise (18 nV/√Hz), higher slew rate (13 V/µs), but 1.4 mA supply current - 7× higher than TL062ACN.	Better for wideband audio; unsuitable for battery-powered or thermally constrained designs.	Choose TL072CP only when bandwidth/noise outweighs power budget constraints.
RC4558P	Bipolar input (not JFET); 500 nA bias current, 0.6 V/µs slew rate, no short-circuit protection.	Acceptable for low-frequency general-purpose use (e.g., tone controls), but fails in high-Z sensor or precision DC applications.	Select RC4558P only for cost-driven non-critical linear circuits where input impedance >1 MΩ suffices.

Compared with TL072CP and RC4558P, TL062ACN uniquely balances ultra-low quiescent current (200 µA), JFET-input impedance (10¹² Ω), and built-in short-circuit protection - making it the optimal choice for dual-channel, low-power, high-impedance analog signal chains where thermal headroom and sensor compatibility are primary constraints.

FAQ

What is the maximum supply voltage for TL062ACN?

The absolute maximum supply voltage is ±18 V (36 V total), but the recommended operating range is ±6 V to ±18 V. Operation beyond ±18 V risks permanent damage due to junction breakdown, and thermal derating is required above +70 °C ambient to maintain safe power dissipation within the 680 mW limit.

Does TL062ACN support single-supply operation?

Yes - TL062ACN supports single-supply operation with input common-mode range extending to V_CC– (ground) and up to V_CC+ – 3 V. For example, with +15 V and ground supplies, inputs can swing from 0 V to +12 V, and output swings from ~1.5 V to ~13.5 V into 10 kΩ, requiring proper biasing of non-inverting inputs for DC-coupled use.

How does TL062ACN differ from TL062CN?

TL062ACN is the "A" grade variant: it specifies tighter input offset voltage (3–7.5 mV vs. 3–20 mV for TL062CN) and lower input offset current (≤100 pA typical vs. ≤200 pA) at +25 °C. Both share identical pinout, package, and temperature range (0 to +70 °C), but TL062ACN offers improved DC precision for applications sensitive to initial calibration drift.

Is TL062ACN RoHS compliant?

Yes - TL062ACN is manufactured in ST's ECOPACK®-compliant DIP8 package, meeting RoHS Directive 2011/65/EU requirements. Lead-free finish and halogen-free molding compound are standard; full compliance documentation is available in ST's ECOPACK database under part number TL062ACN.
