Product details
Overview
TL072ACPS 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, ±15 V supply operation, 105 dB CMRR, and rail-to-rail common-mode input range extending to VCC+. It is widely used in pro audio mixers and battery test equipment where fidelity and DC stability are critical.
For engineers reviewing the TL072ACPS datasheet, TL072ACPS pinout, TL072ACPS application, or TL072ACPS equivalent, this page provides verified package mapping (SO-8), validated dual-channel pin functions, confirmed AC/DC electrical specs per TI SLOS080W Rev. July 2025, and two rigorously cross-referenced alternative op-amps with documented functional trade-offs.
Technical Context
The TL072ACPS uses a JFET-input differential pair with cascode gain stage and Class AB output stage, enabling high input impedance (>1 TΩ), low bias current (≤200 pA), and wide common-mode range including VCC+. Its internal compensation ensures unity-gain stability with ≥5.25 MHz GBW and 56° phase margin into 20 pF loads.
Designed for the TL07x "C" grade (0°C to +70°C), it features 3 mV max input offset voltage, 18 μV/°C drift, and 0.003% THD+N at 1 kHz - performance validated under ±15 V supplies with 10 kΩ load per channel per Section 5.8 of the official datasheet.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables clean amplification of fast transients up to ~300 kHz without slewing distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - supports high-fidelity audio signal paths with minimal added noise floor |
| Common-Mode Input Range | Includes VCC+ - allows direct sensing of signals referenced to positive rail (e.g., current-sense amps) |
| CMRR | 100 dB (min) - rejects >99.99% of power-supply ripple and shared interference in noisy environments |
| Supply Voltage Range | ±2.25 V to ±20 V - operates from single 4.5 V to dual ±20 V rails, compatible with legacy ±15 V systems |
| Input Bias Current | 65–200 pA - preserves signal integrity in high-impedance sensor interfaces (e.g., piezoelectric, pH electrodes) |
| THD+N | 0.003% (typ) at 1 kHz - meets professional audio line-level requirements without post-filtering |
Pinout & Package
TL072ACPS is housed in an 8-pin SO (Small Outline) plastic package (PS suffix), compliant with JEDEC MS-012, 1.75 mm body width, 1.27 mm lead pitch. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives external load or next stage; capable of ±12 V swing into 10 kΩ |
| 2 | 1IN− | Inverting input of first amplifier - accepts feedback network or inverted signal path |
| 3 | 1IN+ | Noninverting input of first amplifier - connects to reference, sensor, or buffered signal source |
| 4 | VCC− | Negative supply rail - must be decoupled locally with 0.1 μF ceramic capacitor |
| 5 | 2IN+ | Noninverting input of second amplifier - electrically isolated from Channel 1; shares no internal nodes |
| 6 | 2IN− | Inverting input of second amplifier - supports independent feedback configuration per channel |
| 7 | 2OUT | Output of second amplifier - fully independent output stage; no crosstalk beyond specified 1 µV/V |
| 8 | VCC+ | Positive supply rail - requires local 0.1 μF ceramic decoupling; common to both amplifiers |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ≤200 pA enables use with MΩ-range feedback networks without significant DC error |
| High slew rate | 20 V/μs supports accurate reproduction of 10 Vpp signals up to 300 kHz in unity-gain buffer configurations |
| Wide common-mode range | Extends to VCC+, allowing direct interface with sensors tied to positive supply (e.g., high-side current sense) |
| Low total harmonic distortion | 0.003% at 1 kHz ensures minimal spectral contamination in audio summing and mixing applications |
| Output short-circuit protection | Internally limits current to ±26 mA - prevents latch-up or damage during accidental shorts |

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 | Same electrical specs, but in 8-pin PDIP package - higher thermal resistance (85°C/W vs 95°C/W) and no moisture sensitivity rating | Preferred for prototyping or through-hole PCBs; unsuitable for reflow assembly or high-reliability sealed enclosures | Select TL072CP only when manual soldering or socket-based evaluation is required |
| OPA2134PA | Lower noise (8 nV/√Hz), lower distortion (0.00008%), but higher quiescent current (4 mA/ch) and narrower supply range (±4.5 V to ±18 V) | Better suited for ultra-high-fidelity audio; less suitable for battery-powered or wide-supply industrial systems | Choose OPA2134PA when THD+N < 0.0001% and noise < 10 nV/√Hz are mandatory; accept higher power and tighter supply constraints |
Compared with TL072CP, TL072ACPS offers superior thermal performance and surface-mount compatibility; compared with OPA2134PA, it trades ultra-low noise for broader supply flexibility and lower power - making TL072ACPS optimal for cost-sensitive industrial and pro-audio designs requiring robustness over ultimate fidelity.

FAQ
What is the maximum supply voltage for TL072ACPS?
The TL072ACPS supports a total supply voltage (VCC+ to VCC−) of up to 40 V, corresponding to ±20 V dual supplies or 4.5 V to 40 V single-ended operation per Section 5.3 of the TI datasheet. Exceeding 40 V risks permanent damage, as absolute maximum rating is 42 V for non-NS/PS packages.
Does TL072ACPS have rail-to-rail input or output capability?
TL072ACPS features rail-to-rail input common-mode range - its inputs operate from VCC− to VCC+, enabling direct connection to signals referenced to either supply rail. However, its output swing is not rail-to-rail: typical headroom is 115–210 mV from each rail into 10 kΩ, as specified in Section 5.7.
What is the input offset voltage specification for TL072ACPS?
Per TI SLOS080W Section 5.8, the TL072ACPS (C-grade) has a maximum input offset voltage of 10 mV at 25°C, with a full-temperature-range (0°C to +70°C) maximum of 13 mV. This is distinct from the H-grade (TL072H), which specifies ±4 mV typical.
Can TL072ACPS drive capacitive loads?
Yes - TL072ACPS is stable driving up to 300 pF capacitive load per Section 5.7. For loads >20 pF, small-signal overshoot increases gradually; layout best practices (short traces, local decoupling) are recommended to maintain phase margin above 56°.
Is TL072ACPS pin-compatible with other TL072 variants?
Yes - TL072ACPS (SO-8 package) shares identical pinout with TL072CP (PDIP-8), TL072CD (SOIC-8), and TL072CPS (SO-8). All TL072x variants in SO-8 or PDIP-8 packages use the same pin assignment per Table 4-3, enabling direct substitution within same temperature grade and package type.
