Texas Instruments TL072BCP

Overview

TL072BCP from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise, high-slew-rate signal conditioning in audio and precision analog circuits. 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 TL072BCP datasheet, TL072BCP pinout, TL072BCP application, or TL072BCP 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 legacy TL072 designs requiring C-grade temperature performance (0°C to 70°C).

Technical Context

The TL072BCP implements a dual-channel, high-impedance JFET differential input stage followed by a Class AB output stage, enabling low distortion (0.003% THD+N) and fast settling (0.56 μs to 0.1% for 2 V step). Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.

It operates across ±2.25 V to ±20 V supplies, supports common-mode input voltages up to VCC+, and features integrated EMI filtering and 2 kV HBM ESD protection-making it suitable for industrial and audio environments with noisy power rails or RF interference.

Key Specifications

Pinout & Package

TL072BCP is housed in an 8-pin PDIP (Plastic Dual In-line Package) with 0.3-inch body width and through-hole mounting. This package provides robust thermal performance (RθJA = 85°C/W) and mechanical stability for prototyping and legacy PCB designs.

FAQ

What is the maximum operating temperature range for TL072BCP?

The TL072BCP is rated for operation from 0°C to 70°C (commercial temperature grade). This range is confirmed in Section 5.3 of the official datasheet under Recommended Operating Conditions for TL07xC devices. It does not support extended industrial or military temperature ranges like the TL072I (–40°C to +85°C) or TL072M (–55°C to +125°C) variants.

Does TL072BCP support rail-to-rail input or output?

TL072BCP supports rail-to-rail input common-mode 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 (per Section 5.7). For true rail-to-rail I/O, consider modern alternatives like OPA2340 or TLV2462, not TL072BCP.

Can TL072BCP be used with single-supply operation?

Yes, TL072BCP 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., VCC/2) using a resistor divider, while the inverting input accepts AC-coupled or level-shifted signals-enabling robust single-supply amplifier designs.

What is the typical input offset voltage for TL072BCP?

The typical input offset voltage for TL072BCP is ±1 mV at 25°C, with a maximum of ±3 mV across the full commercial temperature range (0°C to 70°C). This value is specified in Section 5.8 of the datasheet for TL07xC-grade devices and distinguishes TL072BCP from standard TL072CP (±10 mV max).

Is TL072BCP pin-compatible with other TL072 variants in PDIP-8?

Yes, TL072BCP is fully pin-compatible with all TL072x variants in the 8-pin PDIP package (e.g., TL072CP, TL072IP, TL072M), sharing identical pinout (1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+). Mechanical and electrical interoperability is maintained across temperature grades and suffixes in this package.
