Product details
Overview
TL062BCD from STMicroelectronics is a low-power JFET-input dual operational amplifier in SO-8 package, rated for 0 °C to +70 °C operation, featuring 200 µA supply current per amplifier, 3.5 V/µs slew rate, and ±11.5 V input common-mode range - used in precision signal conditioning stages of industrial sensor interfaces and audio preamplifier circuits.
For engineers reviewing the TL062BCD datasheet, TL062BCD pinout, TL062BCD application, or TL062BCD equivalent, key selection criteria include input bias current (≤200 pA typ), channel separation (120 dB), output swing (20 Vpp into 10 kΩ), and thermal resistance (125 °C/W junction-to-ambient in SO-8).
Technical Context
The TL062BCD integrates two matched high-voltage JFET input stages with bipolar output transistors on a single monolithic die, enabling rail-to-rail-compatible input operation up to VCC and differential input voltage tolerance of ±30 V. Its internal frequency compensation ensures unity-gain stability without external components.
Designed for low-noise, low-drift analog signal paths, it delivers 1 MHz gain-bandwidth product, 86 dB common-mode rejection (typ), and 95 dB supply voltage rejection at ±15 V supply - supporting DC-coupled amplification and active filtering in single-supply or split-supply configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply current | 200 µA per amplifier - enables battery-powered or energy-constrained systems with dual-channel analog front ends |
| Slew rate | 3.5 V/µs - supports faithful reproduction of audio-band signals up to ~100 kHz with minimal distortion |
| Input offset voltage | 3–15 mV max - sets baseline DC error in precision DC-coupled gain stages and instrumentation amplifiers |
| Input bias current | 30–400 pA (typ 200 pA) - preserves signal integrity when driving high-impedance sources like piezoelectric sensors |
| Common-mode range | ±11.5 V (with ±15 V supply) - allows direct interfacing to transducers operating near supply rails |
| Output voltage swing | 20 Vpp into 10 kΩ - delivers usable dynamic range in line-level audio and industrial control loop outputs |
| Gain-bandwidth product | 1 MHz - defines maximum stable closed-loop bandwidth for unity-gain buffers or low-gain amplifiers |
Pinout & Package
TL062BCD is housed in an SO-8 (small-outline integrated circuit, 8-pin) plastic micropackage with standard 1.27 mm pitch, JEDEC MS-012AC compliant, and RoHS-compliant ECOPACK® grade.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Output 1 | Amplified output signal from first op-amp channel; drives loads up to 10 kΩ with 20 Vpp swing |
| 2 | Inverting input 1 | Inverting node of first op-amp; accepts feedback networks for precise gain configuration |
| 3 | Non-inverting input 1 | High-impedance (10¹² Ω) input for reference or sensor signal; supports DC-coupled sensing |
| 4 | VCC– | Negative supply rail connection; referenced to system ground in single-supply use with level-shifting |
| 5 | Non-inverting input 2 | Second op-amp's high-Z input; electrically isolated from Channel 1 for dual independent signal paths |
| 6 | Inverting input 2 | Feedback node for second amplifier; enables simultaneous processing of two analog channels |
| 7 | Output 2 | Dedicated output for second channel; 120 dB channel separation prevents crosstalk in stereo or differential pairs |
| 8 | VCC+ | Positive supply rail; supports 6–36 V total supply range (±3 to ±18 V) for flexible system integration |
Key Features
| Feature | Design Value |
|---|---|
| Very low power consumption | 200 µA per amplifier - extends battery life in portable instrumentation and remote sensor nodes |
| High input impedance JFET stage | 10¹² Ω input resistance - minimizes loading on high-output-impedance sources such as pH electrodes or photodiodes |
| Output short-circuit protection | Indefinite short-circuit duration to either rail - enhances reliability in field-deployed equipment subject to wiring faults |
| Latch-up free operation | Guaranteed under all specified conditions - eliminates risk of destructive latch-up during overvoltage transients |
| Internal frequency compensation | Unity-gain stable without external components - reduces BOM count and layout complexity in basic amplifier designs |

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 |
|---|---|---|---|
| TL072CD | Lower input noise (18 nV/√Hz), higher slew rate (13 V/µs), but 1.4 mA supply current - 7× higher quiescent power | Better for wideband audio or fast transient response; unsuitable for ultra-low-power battery operation | Select TL072CD only when speed/noise outweigh power constraints; verify thermal dissipation in SO-8 package |
| RC4558IDR | Bipolar input (not JFET); 800 µA supply current, 0.6 V/µs slew rate, no guaranteed CMVR beyond ±12 V | Cost-optimized general-purpose use; lacks JFET advantages for high-Z or low-power designs | Choose RC4558IDR for non-critical, high-volume consumer applications where input bias and power are not limiting |
Compared with TL062BCD, TL072CD trades 7× higher supply current for 3.7× faster slew rate and half the input noise, while RC4558IDR sacrifices JFET input benefits for lower cost and wider availability - making TL062BCD optimal for low-power, high-impedance precision analog tasks.

FAQ
What is the maximum supply voltage for TL062BCD?
The absolute maximum supply voltage is ±18 V (36 V total), but the recommended operating range is ±3 V to ±18 V (6–36 V). Operation beyond ±18 V risks permanent damage, and thermal limits must be observed - especially in SO-8 package where RthJA is 125 °C/W.
Does TL062BCD support single-supply operation?
Yes - TL062BCD operates with single supplies from 6 V to 36 V. Its input common-mode range extends to VCC– (but not beyond VCC+), so level-shifting or biasing is required for true rail-to-rail input; output swing remains within 1.5 V of each rail under load.
How does TL062BCD differ from TL062CD?
TL062BCD is the B-grade version (tighter input offset voltage: 2–5 mV max vs. 3–20 mV for C-grade), while TL062CD is the standard C-grade. Both share identical SO-8 packaging, temperature range (0 °C to +70 °C), and electrical specs except offset voltage and its drift - B-grade is preferred for precision DC-coupled applications.
Is TL062BCD pin-compatible with other dual op-amps in SO-8?
Yes - TL062BCD uses industry-standard SO-8 pinout (pin 1 = Output 1, pin 4 = VCC–, pin 8 = VCC+), matching TL072, NE5532, and RC4558 families. However, electrical behavior differs significantly: JFET vs. bipolar input, supply current, and noise performance require circuit revalidation.
