Product details
Overview
TL062CN from STMicroelectronics is a low-power JFET-input dual operational amplifier in an 8-pin DIP package, rated for 0 °C to +70 °C operation. It delivers 3.5 V/µs slew rate, 200 µA supply current per amplifier, ±11.5 V input common-mode range, and 1 MHz gain-bandwidth product - enabling precision signal conditioning in battery-powered instrumentation and audio preamplifier stages.
For engineers reviewing the TL062CN datasheet, TL062CN pinout, TL062CN application, or TL062CN equivalent, key selection criteria include its JFET-input high-impedance (1012 Ω), low input bias current (30–400 pA), output short-circuit protection, and dual-channel isolation (120 dB channel separation) - critical for multi-stage analog front-ends where leakage and crosstalk must be minimized.
Technical Context
The TL062CN 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 1 MHz bandwidth and 3.5 V/µs slew rate under ±15 V supply conditions.
It operates across ±6 V to ±18 V supplies, supports rail-to-rail common-mode input up to VCC±, and maintains 20 V peak-to-peak output swing into 10 kΩ loads. Input offset voltage is specified at 3–20 mV (max), with 10 µV/°C drift and 80–95 dB supply rejection - optimized for DC-coupled sensor interfaces requiring thermal stability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Current | 200–250 µA per amplifier - enables dual-channel operation from microamp-level power rails in portable systems. |
| Slew Rate | 3.5 V/µs - supports clean amplification of audio-band signals (≤100 kHz) without distortion. |
| Input Bias Current | 30–400 pA - preserves signal integrity in high-impedance sensor nodes (e.g., piezoelectric, pH electrodes). |
| Input Resistance | 1012 Ω - minimizes loading on passive filters and capacitive sources. |
| Common-Mode Range | ±11.5 V (with ±15 V supply) - allows direct interfacing to bipolar sensors and industrial transducers. |
| Channel Separation | 120 dB - prevents inter-channel coupling in stereo audio or dual-sensor acquisition paths. |
| Gain-Bandwidth Product | 1 MHz - sets usable closed-loop bandwidth to ~10 kHz at gain = 100, suitable for anti-aliasing and active filtering. |
Pinout & Package
TL062CN is housed in an 8-pin plastic DIP (Dual In-line Package) with 2.54 mm lead pitch, compliant with JEDEC MS-001. The package features through-hole mounting, 85 °C/W junction-to-ambient thermal resistance, and ECOPACK® environmental compliance.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Amplified output of first op-amp channel; capable of ±13.5 V swing into 10 kΩ load. |
| 2 | Inverting Input 1 | High-impedance (1012 Ω) negative feedback node for Channel 1; accepts differential inputs up to ±15 V. |
| 3 | Non-inverting Input 1 | High-impedance positive input for Channel 1; supports common-mode voltages up to VCC+. |
| 4 | VCC− | Negative supply rail connection; must be decoupled locally to minimize noise coupling between channels. |
| 5 | Non-inverting Input 2 | Independent positive input for Channel 2; electrically isolated with 120 dB channel separation. |
| 6 | Inverting Input 2 | Independent negative input for Channel 2; matches Channel 1's bias current and offset specs. |
| 7 | Output 2 | Second independent output; shares same thermal and supply constraints as Output 1. |
| 8 | VCC+ | Positive supply rail; supports ±6 V to ±18 V operation; requires local 100 nF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|

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 vs. 42 nV/√Hz), higher slew rate (13 V/µs), but higher supply current (2.8 mA). | Better suited for wideband audio where noise dominates; less suitable for ultra-low-power sensor nodes. | Choose TL072CP when SNR > 80 dB is required and supply headroom allows >2 mA per channel. |
| RC4558P | Bipolar input (vs. JFET), higher input bias current (30–500 nA), lower input impedance (~300 kΩ), no short-circuit protection. | Cost-optimized for consumer audio where input Z and fault tolerance are secondary. | Choose RC4558P only for non-critical, AC-coupled applications with source impedances <10 kΩ and no fault exposure. |
Compared with TL072CP and RC4558P, TL062CN uniquely balances ultra-low quiescent current (200 µA), JFET-input high impedance (1012 Ω), and output short-circuit protection - making it the only option among the three viable for battery-powered, high-Z, fault-tolerant analog signal chains.

FAQ
What is the maximum supply voltage for TL062CN?
The absolute maximum supply voltage for TL062CN is ±18 V, with recommended operating range of ±6 V to ±18 V. Exceeding ±18 V risks permanent damage to the JFET input stage. Operation at ±15 V yields optimal slew rate (3.5 V/µs) and output swing (20 Vpp into 10 kΩ), while ±12 V remains viable for reduced power consumption.
Does TL062CN support rail-to-rail input or output?
TL062CN supports rail-to-rail common-mode input up to VCC+, meaning its input can accept signals as high as the positive supply rail - a key advantage over standard bipolar op-amps. However, its output swing is limited to ±13.5 V (27 Vpp) under ±15 V supply, not true rail-to-rail; minimum output saturation is typically ±1.5 V from each rail.
How does TL062CN differ from TL062IN?
TL062CN and TL062IN share identical electrical specifications and pinout but differ in temperature grade: TL062CN is rated for 0 °C to +70 °C (commercial), while TL062IN extends to −40 °C to +105 °C (industrial). Both use the same DIP8 package and have identical 200 µA supply current, 3.5 V/µs slew rate, and 120 dB channel separation.
Can TL062CN drive capacitive loads directly?
TL062CN is internally compensated for unity-gain stability with purely resistive loads, but driving >100 pF capacitive loads may cause peaking or oscillation. For capacitive loads >100 pF, a series resistor (typically 100–470 Ω) must be placed between the output pin and the load capacitance to isolate the op-amp's output stage and maintain phase margin.
