Product details
Overview
TL072ID from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise audio and precision signal conditioning. It delivers 20 V/μs slew rate, 37 nV/√Hz input voltage noise at 1 kHz, and ±2.25 V to ±20 V supply operation. Its rail-to-rail common-mode input range (including VCC+) supports high-side sensing in industrial sensor interfaces and pro-audio mixer front-ends.
For engineers reviewing the TL072ID datasheet, TL072ID pinout, TL072ID application, or TL072ID equivalent, key selection criteria include FET-input bias current (<120 pA typ), offset voltage drift (±2 μV/°C), output short-circuit protection, wide supply range, and SOIC-8 package compatibility with legacy TL072 designs.
Technical Context
The TL072ID uses a complementary JFET input stage enabling ultra-low input bias current and high input impedance (>1 TΩ). Its internal compensation ensures stable unity-gain operation with capacitive loads up to 300 pF.
It features integrated EMI/RF filters and 2-kV HBM ESD protection, supporting robust deployment in electrically noisy environments such as motor drive feedback loops and solar inverter voltage monitoring circuits.

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 SOIC-8 package; rated for 0°C to 70°C (commercial temp), higher max offset voltage (10 mV vs 4 mV typ) | Suitable for cost-sensitive consumer audio where extended temperature range is not required | Select TL072CDR only when ambient operating temperature remains within 0°C–70°C and tighter offset specs are unnecessary |
| OPA2134PA | Higher precision (250 μV max offset), lower noise (8 nV/√Hz), but higher quiescent current (4 mA/ch) and no short-circuit protection | Preferred in studio-grade audio where ultimate SNR outweighs power and fault tolerance requirements | Choose OPA2134PA when designing premium audio gear requiring sub-10 μV offset and <10 nV/√Hz noise, accepting higher supply current |
Compared with TL072CDR and OPA2134PA, TL072ID offers the optimal balance of industrial temperature range (–40°C to +85°C), robustness (output short-circuit protection), and low-noise FET input performance-making it ideal for embedded industrial and renewable energy systems where reliability and signal fidelity are both critical.

FAQ
What is the maximum supply voltage for TL072ID?
The TL072ID supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V). Absolute maximum ratings specify 42 V for non-NS/PS packages, but recommended operating conditions limit VS to 40 V to ensure long-term reliability and specified performance across temperature. Exceeding 40 V may degrade offset stability and increase quiescent current beyond datasheet limits.
Does TL072ID have rail-to-rail input or output capability?
The TL072ID 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 the positive rail and 105–215 mV of the negative rail under 10 kΩ load. This partial output swing is sufficient for most industrial interface and audio line-driving applications where headroom margins are acceptable.
Can TL072ID drive capacitive loads directly?
Yes, TL072ID is characterized to safely drive capacitive loads up to 300 pF while maintaining stability and specified phase margin (56°). For loads exceeding 300 pF, external series resistance (typically 10–100 Ω) at the output is recommended to isolate the capacitance and prevent peaking or oscillation-especially critical in active filter and cable-driving applications.
Is TL072ID pin-compatible with older TL072 variants?
Yes, TL072ID uses the standard SOIC-8 (D) package with identical pinout to TL072CP, TL072CN, and TL072CDR. All share the same 1–8 pin assignment: 1OUT, 2IN–, 3IN+, 4VCC–, 5IN+, 6IN–, 7OUT, 8VCC+. No PCB layout changes are required when upgrading from legacy commercial-grade TL072 parts to TL072ID for enhanced temperature range and ESD robustness.
What is the input offset voltage specification for TL072ID?
The TL072ID has a typical input offset voltage of ±1 mV and a maximum of ±4 mV at 25°C, with ±5 mV guaranteed over the full –40°C to +85°C operating range. This performance reflects its "H" suffix designation (TL072H), indicating improved process control versus earlier TL072C/I/M variants, making it suitable for precision DC-coupled gain stages where offset-induced errors must remain below 100 μV.
