Product details

Overview

TL062IDT from STMicroelectronics is a low-power JFET-input dual operational amplifier in SO-8 package, delivering 3.5 V/µs slew rate, ±11.5 V input common-mode range (up to V_CC±), and 200 µA supply current per amplifier. It operates from ±6 V to ±18 V supplies across –40 °C to +105 °C, and is used in precision signal conditioning for industrial sensor interfaces and audio preamplifier stages.

For engineers reviewing the TL062IDT datasheet, TL062IDT pinout, TL062IDT application, or TL062IDT equivalent, key selection considerations include its JFET-input high input impedance (10¹² Ω), low input bias current (30 pA typ.), dual-channel channel separation (120 dB), and SO-8 thermal resistance (R_thJA = 125 °C/W) for thermally constrained PCB layouts.

Technical Context

The TL062IDT integrates matched high-voltage JFET and bipolar transistors on a monolithic die, enabling rail-to-rail-compatible input operation with latch-up-free behavior and internal frequency compensation for unity-gain stability. Its differential pair architecture supports wide common-mode voltage swing beyond supply rails (±11.5 V at ±15 V supply).

Designed for low-noise analog signal paths, it features 42 nV/√Hz input noise at 1 kHz, 80 dB CMRR and SVRR (min), and output short-circuit protection - all while maintaining only 6 mW total quiescent power dissipation at ±15 V.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Voltage Range	±6 V to ±18 V - supports dual-rail industrial power domains without level-shifting.
Slew Rate	3.5 V/µs - enables faithful reproduction of 100 kHz sine waves with <1% distortion at 10 V_PP.
Input Bias Current	30 pA (typ.) - minimizes DC error in high-impedance transducer interfaces (e.g., piezoelectric sensors).
Input Resistance	10¹² Ω - preserves signal integrity in passive filter networks and photodiode amplifiers.
Common-Mode Rejection	80 dB (min) - rejects coupled noise in noisy industrial environments with ground differentials.
Channel Separation	120 dB - prevents crosstalk between dual channels in stereo audio or differential sensor pairs.
Quiescent Current	200 µA per amplifier - allows battery-powered instrumentation with multi-year runtime.

Pinout & Package

TL062IDT uses an SO-8 (small outline integrated circuit) plastic micropackage with standard 1.27 mm pitch, 5.0 mm × 6.0 mm body, and 1.75 mm height - optimized for automated SMT assembly and thermal performance (R_thJA = 125 °C/W).

Pin/Terminal	Circuit Role	Design Meaning
1	Output 1	Low-impedance buffered output of first op-amp channel; capable of ±10 V swing into 10 kΩ.
2	Inverting Input 1	Differential input node for Channel 1; high-Z JFET gate with 30 pA bias current.
3	Non-inverting Input 1	Reference input for Channel 1; shares same high-impedance characteristics as Pin 2.
4	V_CC–	Negative supply rail connection; must be decoupled locally to minimize PSRR degradation.
5	Non-inverting Input 2	Independent reference input for second op-amp; electrically isolated from Channel 1 inputs.
6	Inverting Input 2	Differential input for Channel 2; identical electrical specs to Pin 2.
7	Output 2	Second independent output; 120 dB isolation ensures minimal inter-channel coupling.
8	V_CC+	Positive supply rail; symmetric ±15 V operation yields 27 V_PP output swing.

Key Features

Feature	Design Value
Very low power consumption	200 µA per amplifier enables dual-channel operation under 500 µA total supply current.
High input impedance JFET stage	10¹² Ω input resistance prevents loading of high-Z sources like crystal microphones or pH electrodes.
Output short-circuit protection	Allows safe operation during prototyping or fault conditions without external current limiting.
Wide common-mode voltage range	±11.5 V at ±15 V supply permits direct interfacing to signals near rail voltages without attenuation.
Internal frequency compensation	Guarantees stable unity-gain operation without external compensation components.

Applications

Industrial Sensor Signal Conditioning

Use Scenario: Amplifying low-level mV outputs from RTD, thermocouple, or strain gauge bridges in PLC I/O modules.

IC Role / Device Role / Timing Role: Dual-channel instrumentation amplifier front-end with matched gain and offset tracking.

Use Value: 30 pA input bias current avoids significant offset drift in 100 kΩ+ bridge arms; 80 dB CMRR suppresses 50/60 Hz pickup in factory floors.

Use Scenario: Low-noise microphone preamp and tone control stage in portable audio mixers.

IC Role / Device Role / Timing Role: Dual op-amp implementing non-inverting gain + active EQ filtering.

Use Value: 42 nV/√Hz input noise preserves dynamic range; 120 dB channel separation prevents stereo crosstalk below –100 dB.

Quadrature Oscillator

Active Filter Stage

Use Scenario: Generating synchronized sine/cosine waveforms for encoder interpolation or phase-locked loops.

IC Role / Device Role / Timing Role: Dual op-amp configured as coupled integrators in 100 kHz oscillator topology.

Use Value: 3.5 V/µs slew rate supports clean 100 kHz outputs; low input offset (<6 mV) ensures quadrature accuracy within ±0.5°.

Use Scenario: 2nd-order low-pass filtering in data acquisition anti-aliasing paths.

IC Role / Device Role / Timing Role: Dual op-amp implementing Sallen-Key topology with precise pole placement.

Use Value: Matched internal transistor pairs minimize component tolerance sensitivity; 1 MHz GBP enables cutoff frequencies up to 100 kHz.

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
TL072CDR	Higher slew rate (13 V/µs), lower input noise (18 nV/√Hz), but 1.4 mA supply current.	Better for wideband audio or fast transient response; unsuitable for ultra-low-power battery systems.	Choose when bandwidth >1 MHz and noise <20 nV/√Hz are critical; accept 7× higher quiescent power.
CA3140EZ	BiMOS input (FET + MOS), 0.5 pA input bias, but only 1.5 MHz GBP and no SO-8 option.	Superior for femtoampere-level photodiode current sensing; lacks dual-channel integration and modern packaging.	Prefer for single-channel ultra-high-Z sensor amps; avoid where dual-channel layout density or SO-8 reflow is required.

Compared with TL062IDT, TL072CDR trades 7× higher supply current for 3.7× faster slew rate and half the input noise, while CA3140EZ offers sub-picoampere bias at the cost of bandwidth and package modernity - making TL062IDT optimal for balanced industrial signal chains requiring dual channels, low power, and SO-8 manufacturability.

FAQ

What is the maximum operating temperature range for TL062IDT?

The TL062IDT is rated for operation from –40 °C to +105 °C, matching the TL062I grade specification. This extended temperature range is validated per Table 2 of ST's Doc ID 2294 Rev 4 and supports deployment in industrial motor drives, outdoor sensor nodes, and HVAC control units without derating.

Does TL062IDT require external compensation capacitors?

No - TL062IDT incorporates internal frequency compensation optimized for stable unity-gain operation. The datasheet confirms unconditional stability with capacitive loads ≤100 pF and resistive loads ≥10 kΩ, eliminating need for external compensation in standard configurations.

Can TL062IDT drive a 600 Ω audio load directly?

No - TL062IDT is not specified for 600 Ω loads. Its output stage delivers ±10 V into 10 kΩ (27 V_PP swing), but output current is limited to ±10 mA typical. Driving 600 Ω would require >16 mA peak current and cause severe clipping; a dedicated line driver or buffer stage is required.

Is TL062IDT RoHS-compliant and halogen-free?

Yes - TL062IDT 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 "IDT" suffix denotes tape-and-reel packaging compliant with JEDEC J-STD-020 moisture sensitivity level 1.
