Product details
Overview
TL072BCD 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, ±2.25 V to ±20 V dual-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 FET-input stability and low distortion (0.003% THD+N) are critical.
For engineers reviewing the TL072BCD datasheet, TL072BCD pinout, TL072BCD application, or TL072BCD equivalent, key selection criteria include its dual-channel SOIC-8 package, guaranteed 1 mV max offset voltage (C-grade), 5.25 MHz gain-bandwidth product, and compatibility with ±15 V and single-supply configurations up to 40 V - all validated across 0°C to 70°C industrial temperature range.
Technical Context
The TL072BCD employs a JFET-input differential pair with high-impedance (>1 TΩ common-mode input resistance) and integrated EMI filtering, enabling robust performance in noisy environments. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF while maintaining 56° phase margin.
It operates with quiescent current of 1.4–2.5 mA per amplifier and supports output swing within 115 mV of positive rail and 105 mV of negative rail (at RL = 10 kΩ, VS = 40 V), making it suitable for wide-dynamic-range DC-coupled and AC-coupled amplification stages.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | ±2.25 V to ±20 V (dual) or 4.5 V to 40 V (single); enables flexible biasing in legacy ±15 V systems and modern wide-range supplies. |
| Slew Rate | 20 V/μs (typ); supports clean amplification of fast transients in audio and control-loop feedback paths without slewing distortion. |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz (typ); ensures minimal added noise in low-level sensor signal chains and microphone preamps. |
| Input Offset Voltage | 3–10 mV (max at 25°C, C-grade); provides predictable DC accuracy for non-inverting gain stages and active filters. |
| Gain-Bandwidth Product | 5.25 MHz (typ); allows stable closed-loop gains up to ~50 at 100 kHz for anti-aliasing and tone-control filters. |
| Common-Mode Input Range | Extends to VCC+; permits direct sensing of signals referenced to positive supply, e.g., high-side current monitoring. |
| Total Harmonic Distortion + Noise | 0.003% (typ, 1 kHz); meets fidelity requirements in professional audio mixing and line-level signal routing. |
Pinout & Package
TL072BCD is supplied in an 8-pin SOIC (D) package with standard industry footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Pin 1 is marked by a beveled corner or dot; device orientation follows JEDEC MS-012.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier; capable of sourcing/sinking ±26 mA with rail headroom ≤215 mV. |
| 2 | 1IN− | Inverting input of first amplifier; high-impedance JFET node (IB < 200 pA) for minimal loading on passive networks. |
| 3 | 1IN+ | Noninverting input of first amplifier; common-mode range includes VCC+, enabling level-shifting applications. |
| 4 | VCC− | Negative power supply terminal; must be decoupled locally to minimize PSRR degradation and oscillation risk. |
| 5 | 2IN+ | Noninverting input of second amplifier; electrically isolated from Channel 1 but shares thermal and supply domains. |
| 6 | 2IN− | Inverting input of second amplifier; matched to Pin 2 for differential pair symmetry in instrumentation topologies. |
| 7 | 2OUT | Output of second amplifier; independently buffered and short-circuit protected per channel. |
| 8 | VCC+ | Positive power supply terminal; accepts up to 40 V total supply differential; requires local 0.1 μF ceramic bypass. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | ≤200 pA (max) enables high-Z sensor interfaces (e.g., piezoelectric pickups, pH electrodes) without significant DC error. |
| Output short-circuit protection | Internal current limiting prevents latch-up or destruction during accidental output shorts in test equipment or motor drive feedback loops. |
| Wide supply voltage range | Supports both legacy ±15 V rails and modern 24 V single-ended industrial buses without external level-shifting. |
| Low total harmonic distortion | 0.003% THD+N preserves signal integrity in audio summing amplifiers and active crossover networks. |
| Integrated EMI filtering | On-die RF rejection (53 dB at 1 GHz) suppresses switching noise from nearby DC/DC converters in mixed-signal PCBs. |

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 electrical specs and SOIC-8 package; RoHS-compliant tape-and-reel variant with identical 0°C to 70°C rating. | No functional difference; optimized for automated SMT assembly with moisture-sensitive level (MSL) 1 handling. | Select when volume production requires reel packaging and full RoHS compliance without design change. |
| RC4558DR | Bipolar-input architecture; higher input bias current (500 nA), lower slew rate (1.7 V/μs), but wider temp range (–40°C to 85°C) and lower cost. | Acceptable for non-critical audio buffering or general-purpose gain stages where noise and speed are secondary. | Choose only if budget constraints outweigh need for low-noise, high-speed performance - not a drop-in replacement. |

FAQ
What is the maximum supply voltage for TL072BCD?
The TL072BCD supports a total supply voltage range of ±2.25 V to ±20 V (dual supply) or 4.5 V to 40 V (single supply). Absolute maximum ratings specify 42 V differential supply for non-NS/PS packages; however, recommended operating conditions limit VS to 40 V to ensure reliability and specified performance across 0°C to 70°C ambient.
Does TL072BCD have rail-to-rail output capability?
No, TL072BCD does not feature rail-to-rail output. Its output swing is limited to within 115 mV of the positive rail and 105 mV of the negative rail (at RL = 10 kΩ, VS = 40 V). This headroom requirement must be accounted for in circuit design to avoid clipping, especially in low-voltage or high-gain configurations.
Can TL072BCD operate from a single 5-V supply?
Yes, TL072BCD can operate from a single 5-V supply, as its minimum total supply voltage is 4.5 V. However, input common-mode range extends only to VCC– + 1.5 V and VCC+, so with 5 V supply, usable input range is approximately 1.5 V to 5 V. Output swing will be similarly constrained - design must ensure signal stays within these bounds.
What is the input offset voltage specification for TL072BCD?
The TL072BCD has a maximum input offset voltage of 10 mV at 25°C (typical 3 mV), with full-range specification of 13 mV across 0°C to 70°C. This value is consistent with the "C" grade of the TL072x family and is verified per Section 5.8 of the official TI datasheet SLOS080W.
Is TL072BCD pin-compatible with other TL072 variants like TL072CP or TL072ACD?
Yes, TL072BCD is pin-compatible with all TL072x variants in SOIC-8 (D) package, including TL072CP (PDIP-8) and TL072ACD (SOIC-8 with tighter 6 mV offset spec). Mechanical pinout and function match exactly per Table 4-3 of the datasheet; differences lie only in electrical grading (B vs A vs C) and package type - no PCB redesign is needed when substituting within same package.
