Product details
Overview
TL072ACPSR from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V 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 high fidelity and DC accuracy are critical.
For engineers reviewing the TL072ACPSR datasheet, TL072ACPSR pinout, TL072ACPSR application, or TL072ACPSR equivalent, this page provides verified specifications, SO-8 package terminal mapping, real-world use cases in audio and power test systems, and two validated alternative op-amps with documented functional and thermal differences.
Technical Context
The TL072ACPSR uses a dual JFET-input stage with high-impedance differential pair architecture, enabling ultra-low input bias current (≤120 pA typ) and low offset drift (2 μV/°C). Its internal compensation ensures stable unity-gain operation with ≥56° phase margin and 5.25 MHz gain-bandwidth product.
It supports wide-supply operation (±2.25 V to ±20 V), features output short-circuit protection, and includes integrated EMI/RF filters. The device meets industrial temperature requirements (–40°C to +85°C) and offers 100 dB CMRR and 105 dB PSRR at DC.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|

| Gain-Bandwidth Product | 5.25 MHz - supports stable closed-loop designs up to ~100 kHz at moderate gains |
Pinout & Package
TL072ACPSR is housed in an 8-pin SO (Small Outline) plastic package (PS), compliant with JEDEC MS-012, with 1.27 mm pitch and gull-wing leads. The package is RoHS-compliant and rated for surface-mount reflow.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives loads up to ±26 mA with 115–210 mV headroom to positive rail |
| 2 | 1IN− | Inverting input of first amplifier - high-impedance JFET node (ZICM = 6 TΩ || 1 pF) |
| 3 | 1IN+ | Noninverting input of first amplifier - accepts common-mode voltages up to VCC+ |
| 4 | VCC− | Negative supply rail - must be decoupled locally to minimize noise coupling |
| 5 | 2IN+ | Noninverting input of second amplifier - electrically isolated from Channel 1 per datasheet channel separation spec (10 µV/V) |
| 6 | 2IN− | Inverting input of second amplifier - matched to Pin 2 for balanced differential stages |
| 7 | 2OUT | Output of second amplifier - identical AC/DC specs to Pin 1 |
| 8 | VCC+ | Positive supply rail - supports rail-to-rail input and supplies 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 |
|---|---|---|---|
| TL072CDR | Same SO-8 package; wider offset voltage range (3–10 mV vs. 1–4 mV typ); higher quiescent current (1.4–2.5 mA/ch vs. 0.94 mA/ch) | Lower DC precision and higher power draw limit use in battery-powered or high-accuracy systems | Select TL072CDR only when cost sensitivity outweighs need for low noise and low drift |
| OPA2134PA | Higher price; lower noise (8 nV/√Hz); lower input bias (1 pA); rail-to-rail output; no short-circuit protection | Superior audio performance but lacks robustness in industrial fault conditions | Choose OPA2134PA for premium audio design where output protection is externally managed |
Compared with TL072CDR and OPA2134PA, TL072ACPSR uniquely balances low noise (37 nV/√Hz), low drift (2 μV/°C), built-in short-circuit protection, and SO-8 compatibility-making it optimal for cost-constrained industrial audio and test instrumentation requiring reliability and precision.

FAQ
What is the maximum supply voltage for TL072ACPSR?
The TL072ACPSR supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V), with absolute maximum ratings of –0.3 V to +36 V on VCC+ and VCC– pins for NS and PS packages. Operation beyond ±20 V requires verification against derating curves in the datasheet thermal tables.
Does TL072ACPSR have rail-to-rail output capability?
No, TL072ACPSR does not provide rail-to-rail output swing. At VS = 40 V and RL = 10 kΩ, its output swings within 115–210 mV of the positive rail and 105–215 mV of the negative rail. This limited headroom is typical of older JFET-input op-amps and must be accounted for in gain-stage design.
How does TL072ACPSR differ from TL072H variants?
TL072ACPSR belongs to the TL072C grade (0°C to +70°C), while TL072H specifies –40°C to +125°C operation and tighter offset voltage (±1 mV typ vs. ±3 mV typ). TL072ACPSR uses the legacy die (Section 5.8/5.9), whereas TL072H uses the newer H-die with improved noise and drift specs.
Can TL072ACPSR drive capacitive loads?
Yes, TL072ACPSR can safely drive up to 300 pF capacitive load without instability, as confirmed by small-signal overshoot testing in the datasheet. For loads >300 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended to maintain phase margin.
Is TL072ACPSR pin-compatible with other TL072 variants in SO-8?
Yes, TL072ACPSR shares identical pinout and SO-8 (PS) package dimensions with all TL072x variants including TL072CDR, TL072IDR, and TL072CP. Mechanical and electrical pin compatibility is guaranteed across the TL072 family for this package type.
