Product details

Overview

TL072ACDT from STMicroelectronics is a low-noise JFET-input dual operational amplifier in SO8 package, rated for 0 °C to +70 °C operation, with 16 V/µs slew rate, 15 nV/√Hz input voltage noise, and ±11 V common-mode input range. It serves as a precision signal conditioning amplifier in audio preamps, sensor interfaces, and active filters.

For engineers reviewing the TL072ACDT datasheet, TL072ACDT pinout, TL072ACDT application, or TL072ACDT equivalent, this page delivers verified electrical parameters, validated SO8 pin mapping, real-world use cases in analog signal chains, and functionally comparable alternatives with documented performance trade-offs.

Technical Context

The TL072ACDT integrates two matched high-voltage JFET input stages with bipolar output stages on a single monolithic die, enabling rail-to-rail-compatible common-mode operation up to ±15 V with internal frequency compensation. Its JFET front-end delivers ultra-low input bias current (20 pA typ) and high input impedance (10¹² Ω).

It achieves 2.5–4 MHz gain-bandwidth product and 80–86 dB supply voltage rejection at ±15 V supply, supporting stable unity-gain and closed-loop configurations without external compensation. Channel separation exceeds 120 dB at Av = 100, minimizing crosstalk in dual-channel designs.

Key Specifications

Parameter	Value and Actual Design Meaning
Slew Rate	16 V/µs typical - enables clean amplification of fast-slewing audio or control signals up to ~100 kHz without distortion
Input Voltage Noise	15 nV/√Hz at 1 kHz - critical for low-level sensor signal integrity in instrumentation and microphone preamps
Input Bias Current	20 pA typical at +25 °C - preserves accuracy in high-impedance source networks (e.g., piezoelectric sensors)
Common-Mode Range	±11 V at ±15 V supply - supports operation with inputs near negative rail, unlike many bipolar op-amps
Supply Voltage Range	±3 V to ±18 V (6–36 V total) - compatible with legacy ±15 V analog systems and modern low-voltage industrial rails
THD	0.01 % typical at 1 kHz - meets fidelity requirements for line-level audio signal processing
Gain-Bandwidth Product	4 MHz typical - allows stable closed-loop gains up to ~40 at 100 kHz

Pinout & Package

TL072ACDT is housed in an 8-pin SO8 (Small Outline) surface-mount package per JEDEC MS-012, with 1.27 mm pitch, 4.9 mm body width, and 6.0 mm length. Thermal resistance junction-to-ambient is 125 °C/W.

Pin/Terminal	Circuit Role	Design Meaning
1	Output 1	Amplified output of first op-amp channel; drives loads up to 60 mA short-circuit current
2	Inverting Input 1	Negative feedback node for channel 1; high-impedance JFET input (10¹² Ω)
3	Non-inverting Input 1	Positive input for channel 1; supports common-mode voltages up to ±11 V
4	VCC−	Negative supply rail connection; must be referenced to system ground midpoint in split-supply configs
5	Non-inverting Input 2	Positive input for second op-amp channel; electrically isolated but thermally coupled to channel 1
6	Inverting Input 2	Negative feedback node for channel 2; identical bias and noise specs to pin 2
7	Output 2	Amplified output of second channel; independent operation with >120 dB channel separation
8	VCC+	Positive supply rail connection; supports up to +18 V absolute max rating

Key Features

Feature	Design Value
Low Input Bias Current	20 pA typical - minimizes DC error in transimpedance amplifiers and high-Z sensor buffers
High Common-Mode Rejection	86 dB typical - rejects interference in differential measurement circuits with unbalanced source impedances
Output Short-Circuit Protection	Infinite duration rating - enables robust operation in fault-prone industrial I/O modules without external current limiting
Latch-Up Free Operation	Guaranteed under all specified conditions - eliminates risk of destructive parasitic conduction during overvoltage transients
Internal Frequency Compensation	Unity-gain stable - eliminates need for external compensation capacitors in standard gain configurations

Applications

Audio Pre-amplifier

Temperature Sensor Interface

Use Scenario: Amplifying low-level output from electret condenser microphones before ADC sampling in voice-recognition edge devices.

IC Role / Device Role / Timing Role: Dual-channel voltage amplifier providing 40 dB gain with <0.01% THD and minimal added noise floor.

Use Value: 15 nV/√Hz input noise preserves SNR of weak acoustic signals; JFET input avoids loading high-impedance mic capsule.

Use Scenario: Conditioning output from platinum RTD (PT100) bridges in HVAC temperature controllers.

IC Role / Device Role / Timing Role: Instrumentation-grade buffer and gain stage with matched dual channels for 3-wire RTD excitation and sensing.

Use Value: 20 pA input bias current prevents self-heating errors in high-resistance RTD legs; ±11 V common-mode range accommodates bridge offset.

Active Bandpass Filter

DC Motor Speed Reference

Use Scenario: 2nd-order bandpass filter centered at 1 kHz in vibration monitoring systems for bearing fault detection.

IC Role / Device Role / Timing Role: Dual op-amp implementing twin-T or multiple-feedback topology with precise component matching.

Use Value: 4 MHz GBW ensures flat response across passband; >120 dB channel separation prevents coupling between filter sections.

Use Scenario: Generating stable 0–5 V speed reference voltage from PWM input in industrial motor drives.

IC Role / Device Role / Timing Role: Low-drift integrator and buffer converting filtered PWM to analog setpoint for PID controller input.

Use Value: 10 µV/°C input offset drift maintains reference accuracy across 0–70 °C ambient; output swing ≥12 V into 10 kΩ load.

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
TL072CDT	Same SO8 package and pinout; wider input offset voltage spec (3–10 mV vs. TL072ACDT's 3–6 mV), identical noise and slew rate	Acceptable where tighter Vio tolerance is not required; lower cost in volume production	Select when budget constraints outweigh need for improved DC precision
OPA2134PA	Lower input voltage noise (8 nV/√Hz), higher GBW (8 MHz), but higher supply current (4 mA vs. 2.5 mA); DIP-8/SO-8 pin-compatible	Better suited for high-fidelity audio; less suitable for battery-powered sensor nodes due to current draw	Choose for premium audio paths requiring sub-10 nV/√Hz noise and faster settling

Compared with TL072CDT, TL072ACDT offers tighter input offset voltage tolerance for improved DC accuracy in precision gain stages; compared with OPA2134PA, it trades 33% lower quiescent current and proven industrial reliability for higher noise and reduced bandwidth-making it optimal for cost-sensitive, medium-speed analog signal chains.

FAQ

Is TL072ACDT pin-compatible with other TL072 variants?

Yes, TL072ACDT shares identical SO8 pinout and footprint with all TL072 family members (e.g., TL072CDT, TL072IDT). Electrical differences-such as input offset voltage (3–6 mV for 'A' grade vs. 3–10 mV for 'C') and operating temperature range (0–70 °C)-do not affect mechanical or connection compatibility.

What is the maximum safe supply voltage for TL072ACDT?

The absolute maximum supply voltage is ±18 V (36 V total), but continuous operation above ±15 V requires derating based on thermal limits. At ±15 V, junction temperature must remain below 125 °C; with SO8 R_thJA = 125 °C/W, power dissipation must stay under 100 mW per amplifier to avoid thermal runaway.

Does TL072ACDT require external compensation capacitors?

No. TL072ACDT features internal frequency compensation optimized for unity-gain stability. It operates reliably without external capacitors in standard inverting, non-inverting, and voltage-follower configurations-verified across its full specified temperature and supply range.

Can TL072ACDT drive capacitive loads directly?

It can drive ≤100 pF capacitive loads stably in unity-gain configuration, as characterized in the datasheet. For larger loads (e.g., cables or ADC input capacitance), a series isolation resistor (≥100 Ω) is recommended between output and capacitance to maintain phase margin and prevent oscillation.
