Product details

Overview

TL062BCDT from STMicroelectronics is a low-power JFET-input dual operational amplifier in SO-8 package, rated for 0 °C to +70 °C operation, delivering 3.5 V/µs slew rate, 1 MHz gain-bandwidth product, and 200 µA supply current per amplifier-used in precision analog signal conditioning, active filters, and sensor interface circuits where low input bias current (<30 pA typ.) and high input impedance (10¹² Ω) are critical.

For engineers reviewing the TL062BCDT datasheet, TL062BCDT pinout, TL062BCDT application, or TL062BCDT equivalent, this page provides verified pin functions, real-world operating limits (±15 V supply, ±11.5 V common-mode range), channel separation (120 dB), thermal resistance (125 °C/W junction-to-ambient), and validated alternatives for industrial analog signal chains.

Technical Context

The TL062BCDT integrates two matched JFET-input op-amp cores on a single monolithic die, using high-voltage JFETs for ultra-low input bias current and bipolar transistors for robust output drive. Its internal frequency compensation ensures unity-gain stability without external components.

It operates across ±6 V to ±18 V dual supplies (or 12–36 V single supply), supports rail-to-rail input common-mode range up to V_CC+, and features output short-circuit protection with infinite duration rating under thermal limits-enabling reliable use in unregulated or noisy supply environments.

Key Specifications

Parameter	Value and Actual Design Meaning
Supply Current	200 µA per amplifier - enables battery-powered or energy-constrained designs with minimal quiescent power draw
Slew Rate	3.5 V/µs - supports clean amplification of signals up to ~100 kHz at unity gain without distortion
Gain Bandwidth Product	1 MHz - defines maximum stable closed-loop bandwidth at given gain (e.g., 100 kHz at G = 10)
Input Offset Voltage	3–15 mV max (TL062C grade) - sets baseline DC error in precision DC-coupled stages
Input Bias Current	30 pA typ. at +25 °C - preserves signal integrity in high-impedance sensor interfaces (e.g., piezoelectric, pH electrodes)
Common-Mode Range	±11.5 V (with ±15 V supply) - allows input signals to swing within 3.5 V of either rail, simplifying level-shifting
Output Voltage Swing	±10 V min into 10 kΩ - delivers usable dynamic range near supply rails for analog-to-digital conversion front-ends

Pinout & Package

TL062BCDT is housed in an SO-8 (small-outline integrated circuit, 150 mil width) plastic micropackage compliant with ECOPACK® environmental standards. Thermal resistance is 125 °C/W (junction-to-ambient) and 40 °C/W (junction-to-case).

Pin/Terminal	Circuit Role	Design Meaning
1	Output 1	Amplified output of first op-amp channel; capable of sourcing/sinking ±20 mA under short-circuit protection
2	Inverting Input 1	High-impedance (10¹² Ω) JFET node; bias current <30 pA enables high-Z feedback networks
3	Non-inverting Input 1	Matches Pin 2 in offset and bias specs; used for unity-gain buffers or non-inverting configurations
4	V_CC−	Negative supply rail connection; must be decoupled locally to minimize noise coupling between channels
5	Non-inverting Input 2	Independent second channel input; electrically isolated from Channel 1 except via shared supply pins
6	Inverting Input 2	Matches Pin 2 performance; supports dual-channel active filtering or differential signal processing
7	Output 2	Second independent output; channel separation >120 dB prevents crosstalk in multi-stage analog paths
8	V_CC+	Positive supply rail; total device supply current is 400 µA max (2 × 200 µA) at room temperature

Key Features

Feature	Design Value
Very low power consumption	200 µA per amplifier - extends battery life in portable instrumentation and remote sensors
High input impedance JFET stage	10¹² Ω input resistance - avoids loading of high-impedance sources like photodiodes or ceramic microphones
Output short-circuit protection	Infinite duration rating - eliminates need for external current-limiting resistors in fault-prone industrial I/O
Latch-up free operation	Guaranteed over full temp/voltage range - prevents destructive failure during power sequencing or ESD events
Wide common-mode voltage range	Up to V_CC+ - enables direct interfacing with sensors referenced to positive rail (e.g., current-sense amps)

Applications

Audio Pre-amplifier

Active Low-pass Filter

Use Scenario: Amplifying weak microphone or piezoelectric sensor outputs before ADC sampling in portable audio recorders.

IC Role / Device Role / Timing Role: First-stage non-inverting amplifier with gain = 100, configured with 10 MΩ feedback resistor and 100 kΩ input resistor.

Use Value: Ultra-low input bias current (30 pA) prevents DC drift and preserves signal fidelity from high-impedance sources.

IC Role / Device Role / Timing Role: Dual-channel Sallen-Key topology implementing 2nd-order 1 kHz low-pass response with matched component ratios.

Use Value: 120 dB channel separation prevents feedthrough between filter stages, ensuring accurate cutoff roll-off.

DC-Coupled Sensor Interface

Quadrature Oscillator

IC Role / Device Role / Timing Role: Unity-gain buffer followed by precision instrumentation amplifier stage; both channels used for reference and signal paths.

Use Value: ±11.5 V common-mode range allows direct connection to electrode without level-shifting circuitry.

Use Scenario: Generating synchronized sine/cosine waveforms for resolver-to-digital conversion in motor control systems.

Use Value: Matched slew rate (3.5 V/µs) and gain-bandwidth (1 MHz) ensure identical phase response across both channels.

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
TL072CDT	Lower input offset voltage (10 mV max vs. 15 mV), higher slew rate (13 V/µs), but 1.4× higher supply current (2.8 mA vs. 400 µA)	Better for wideband AC-coupled audio; unsuitable for ultra-low-power battery operation	Select when speed and DC precision outweigh power budget constraints
RC4558D	Bipolar input (vs. JFET); 500 nA input bias current (16,000× higher), no rail-to-rail input, lower CMRR (70 dB)	Acceptable for cost-sensitive consumer audio where sensor interface isn't required	Choose only for legacy replacement in non-critical, low-impedance signal paths

Compared with TL062BCDT, TL072CDT trades 7× higher power for 4× faster response and tighter DC specs, while RC4558D sacrifices JFET advantages for cost-making TL062BCDT optimal for low-power, high-Z analog front-ends where input current and supply efficiency are design-critical.

FAQ

What is the maximum supply voltage for TL062BCDT?

The absolute maximum supply voltage is ±18 V (36 V total). Operation beyond this risks permanent damage. For reliable long-term use, ST specifies 6–36 V total supply range (±3 V to ±18 V), with typical applications using ±12 V or ±15 V dual supplies to maximize output swing and headroom.

Does TL062BCDT support single-supply operation?

Yes-TL062BCDT operates with single supplies from 12 V to 36 V. Its input common-mode range extends to V_CC− (ground) and up to V_CC+, enabling true rail-to-rail input capability. Output swing remains limited to ~2 V below V_CC+ and ~2 V above V_CC−, so mid-rail biasing is required for AC signals.

How does TL062BCDT differ from TL062CDT?

TL062BCDT is the B-grade version: it offers tighter input offset voltage (2–5 mV max vs. 3–20 mV for C-grade) and lower input offset voltage drift (10 µV/°C vs. unspecified for C-grade). Both share identical pinout, package, supply range, and temperature rating (0 °C to +70 °C), making them drop-in replacements where enhanced DC precision is needed.

Is TL062BCDT RoHS-compliant and lead-free?

Yes-TL062BCDT is manufactured in ST's ECOPACK®-compliant SO-8 package, meeting RoHS Directive 2011/65/EU and REACH regulations. The device uses lead-free terminations and halogen-free molding compound, with full compliance documented in ST's official material declarations and packaging data sheets.
