Texas Instruments TL072IP

Overview

TL072IP from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in audio and precision analog systems. 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 fidelity and DC stability are critical.

For engineers reviewing the TL072IP datasheet, TL072IP pinout, TL072IP application, or TL072IP equivalent, key selection considerations include its FET-input architecture for ultra-low bias current (±1 pA typ), wide supply flexibility, output short-circuit protection, and compatibility with single- or dual-supply configurations in instrumentation-grade circuits.

Technical Context

The TL072IP uses a dual JFET-input differential pair architecture enabling femtoampere-level input bias currents and low input offset voltage drift (±2 μV/°C). Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF while maintaining 5.25 MHz gain-bandwidth product and 56° phase margin.

It supports common-mode input voltages up to the positive supply rail (VCC+), operates across –40°C to +85°C, and features integrated EMI/RF filters plus 2 kV HBM ESD rating - making it suitable for industrial and audio environments with noisy power or layout constraints.

FAQ

What is the maximum supply voltage for TL072IP?

The TL072IP supports a total supply voltage (VCC+ to VCC–) of up to 40 V, corresponding to ±20 V dual supply or 40 V single supply. Absolute maximum ratings specify 42 V for non-NS/PS packages, but recommended operating conditions limit continuous use to 40 V to ensure reliability and parametric compliance across temperature.

Does TL072IP have rail-to-rail output capability?

No, TL072IP does not feature rail-to-rail output. Its output voltage swing is typically within 115–210 mV of the positive rail and 105–215 mV of the negative rail under 10 kΩ load at ±20 V supply. This headroom must be accounted for in circuit design to avoid clipping near supply limits.

Can TL072IP operate on a single supply?

Yes, TL072IP supports single-supply operation from 4.5 V to 40 V. Its common-mode input range extends to VCC+, allowing the noninverting input to be biased at mid-supply (e.g., via resistor divider) while accepting signals referenced to ground - a key enabler for single-supply audio and sensor front-ends.

What is the input bias current specification for TL072IP?

The TL072IP exhibits an input bias current of ±1 pA typical at 25°C, with a maximum of ±120 pA over temperature. This ultra-low value stems from its JFET-input stage and makes it ideal for integrating capacitors, photodiode amplifiers, and other high-impedance applications where leakage would otherwise dominate error.

Is TL072IP pin-compatible with other TL072 variants like TL072CP or TL072CDR?

Yes, TL072IP (PDIP-8) is pin-compatible with TL072CP (same package) and TL072CDR (SOIC-8), sharing identical pin functions and electrical behavior. However, thermal and packaging differences affect PCB layout and thermal management - SOIC versions require different footprint and may exhibit slightly higher RθJA.
