Product details
Overview
TL072ACDR from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise, high-slew-rate precision signal conditioning in audio and industrial analog circuits. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V dual-supply operation, and rail-to-rail common-mode input range extending to VCC+. It is widely used in pro audio mixers and battery test equipment where low distortion (0.003% THD+N) and stable DC performance are critical.
For engineers reviewing the TL072ACDR datasheet, TL072ACDR pinout, TL072ACDR application, or TL072ACDR equivalent, key selection considerations include its FET-input architecture for ultra-low bias current (±120 pA typ), wide supply flexibility, offset voltage drift of ±2 μV/°C, and SOIC-8 packaging suitable for space-constrained PCB layouts with thermal resistance RθJA = 147.8°C/W.
Technical Context
The TL072ACDR implements a dual-channel, high-impedance JFET differential input stage followed by a Class AB output stage with short-circuit protection. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
It operates across 0°C to 70°C ambient temperature (Commercial grade), supports common-mode input voltages up to VCC+, and maintains 105 dB CMRR and 125 dB open-loop gain under 40 V supply conditions - enabling accurate DC-coupled amplification and filtering in multi-stage analog signal chains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Dual independent op-amps in single SOIC-8 package |
| Slew Rate | 20 V/μs - enables faithful reproduction of fast transients in audio and control loops |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - critical for low-level sensor signal amplification without added noise floor |
| Input Bias Current | ±120 pA typical - preserves signal integrity in high-impedance source networks (e.g., piezoelectric sensors) |
| Supply Voltage Range | ±2.25 V to ±20 V (or 4.5 V to 40 V single-ended) - supports legacy ±15 V rails and modern low-voltage systems |
| Offset Voltage Drift | ±2 μV/°C - ensures stable DC operating point over temperature in precision instrumentation |
| Total Harmonic Distortion + Noise | 0.003% at 1 kHz - meets fidelity requirements in professional audio mixing applications |
Pinout & Package
TL072ACDR is housed in an 8-pin SOIC (Small Outline Integrated Circuit) package with standard JEDEC MS-012AC footprint, 1.27 mm pitch, and 4.9 mm × 3.9 mm body size. Thermal resistance is RθJA = 147.8°C/W, supporting reliable operation at ambient temperatures up to +70°C.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier channel - drives external load or next stage with ±13.5 V swing into 10 kΩ |
| 2 | 1IN− | Inverting input of first amplifier - accepts feedback network for stable closed-loop gain configuration |
| 3 | 1IN+ | Noninverting input of first amplifier - connects to high-impedance signal source with minimal loading |
| 4 | VCC− | Negative power supply rail - must be decoupled locally to minimize noise coupling |
| 5 | 2IN+ | Noninverting input of second amplifier - electrically isolated from Channel 1 for dual-path signal processing |
| 6 | 2IN− | Inverting input of second amplifier - supports independent gain-setting resistor network |
| 7 | 2OUT | Output of second amplifier channel - provides matched AC/DC performance to Channel 1 |
| 8 | VCC+ | Positive power supply rail - requires local 0.1 μF ceramic bypass capacitor to ground |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±120 pA typical - avoids signal attenuation in megohm-range sensor interfaces |
| Wide Common-Mode Range | Includes VCC+ - allows direct sensing of signals referenced to positive rail (e.g., current-sense amps) |
| Output Short-Circuit Protection | ±26 mA continuous short-circuit current limit - prevents latch-up or thermal runaway during fault conditions |
| EMI/RF Immunity | Integrated EMI filters and 53 dB EMI rejection ratio at 1 GHz - reduces susceptibility to switching noise in mixed-signal boards |
| Low Power Consumption | 940 μA per channel - enables dual-amplifier functionality within tight power budgets (e.g., portable test gear) |

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 |
|---|---|---|---|
| TL072CDR | Higher input offset voltage (3 mV max vs 1 mV max for TL072H variants); same SOIC-8 package and pinout | Lower DC precision; acceptable for AC-coupled audio but not high-accuracy DC measurement | Select TL072CDR only when cost sensitivity outweighs need for sub-mV offset and low drift |
| OPA2134PA | Lower noise (8 nV/√Hz), lower THD+N (0.00008%), higher quiescent current (4 mA/ch), DIP-8/SOIC-8 package | Superior audio fidelity and DC accuracy; requires higher supply current budget | Choose OPA2134PA for premium pro-audio designs where noise and distortion are primary constraints |
Compared with TL072CDR and OPA2134PA, the TL072ACDR offers balanced performance: lower offset and drift than TL072CDR while consuming less power than OPA2134PA - making it optimal for cost-sensitive industrial and audio applications requiring verified 0.003% THD+N and 37 nV/√Hz noise.

FAQ
What is the maximum supply voltage rating for TL072ACDR?
The TL072ACDR supports a total supply voltage (VCC+ to VCC−) of up to 40 V (±20 V). Absolute maximum ratings specify 42 V for non-NS/PS packages, but recommended operating conditions limit it to 40 V to ensure long-term reliability and specified performance across temperature.
Does TL072ACDR have rail-to-rail input or output capability?
The TL072ACDR features rail-to-rail common-mode input voltage range - including VCC+ - but does not provide rail-to-rail output swing. Its output typically swings within 115–210 mV of each rail under 10 kΩ load, limiting full-scale utilization in low-voltage single-supply configurations.
Can TL072ACDR drive capacitive loads directly?
Yes, the TL072ACDR is characterized to safely drive capacitive loads up to 300 pF while maintaining stability. For loads exceeding this value, external isolation resistance (e.g., 10–100 Ω in series with the output) is recommended to prevent peaking or oscillation.
What is the input offset voltage specification for TL072ACDR?
The TL072ACDR has a maximum input offset voltage of 10 mV at 25°C (per TL07xC spec table), with typical value of 3 mV. This differs from the TL072H variant (1 mV typical); the 'A' suffix denotes improved initial offset over standard 'C' grade but not H-grade precision.
Is TL072ACDR suitable for single-supply operation?
Yes, TL072ACDR supports single-supply operation from 4.5 V to 40 V. Its input common-mode range extends to VCC+, allowing direct interfacing with sensors referenced to the positive rail - though output swing remains limited near both rails, requiring proper level-shifting for true single-supply signal chain design.
