Product details
Overview
TL072BCDG4 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, ±2.25 V to ±20 V supply operation, and 1 mV typical input offset voltage - enabling high-fidelity preamplification in pro-audio mixers and sensor front-ends.
For engineers reviewing the TL072BCDG4 datasheet, TL072BCDG4 pinout, TL072BCDG4 application, or TL072BCDG4 equivalent, this page provides verified specifications, SOIC-8 package layout, real-world use cases in solar inverters and battery test equipment, and validated alternative options for design continuity.
Technical Context
The TL072BCDG4 implements a dual-channel, high-slew-rate JFET-input architecture with rail-to-rail common-mode input range extending to VCC+, enabling operation in single-supply configurations. Its internal compensation ensures unity-gain stability with capacitive loads up to 300 pF.
Each amplifier features independent input bias current below 120 pA (typ), differential input resistance >1 TΩ, and integrated EMI/RF filtering - supporting robust performance in electrically noisy industrial environments like motor drive power-stage modules.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables accurate reproduction of fast transients in audio and control loops without slew-induced distortion |
| Input Voltage Noise | 37 nV/√Hz at 1 kHz - supports low-noise amplification of microvolt-level sensor signals |
| Input Offset Voltage | ±1 mV (typ) - reduces DC error in precision instrumentation and closed-loop feedback paths |
| Supply Voltage Range | ±2.25 V to ±20 V (4.5 V to 40 V) - accommodates both low-voltage portable systems and high-voltage industrial rails |
| Common-Mode Input Range | Includes VCC+ - allows direct sensing of signals referenced to positive supply, simplifying single-supply designs |
| Quiescent Current | 940 μA per channel (typ) - balances low power consumption with high-speed performance for battery-aware systems |
| Gain-Bandwidth Product | 5.25 MHz - supports stable unity-gain buffers and moderate-gain filters up to ~100 kHz |
Pinout & Package
TL072BCDG4 is housed in an 8-pin SOIC (D) package with standard industry footprint and thermal characteristics (RθJA = 147.8°C/W). Pin functions are fully compatible with legacy TL072 variants and widely adopted op-amp layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives downstream stages with ±12 V swing into 10 kΩ load |
| 2 | 1IN− | Inverting input of first amplifier - accepts feedback network for stable gain configuration |
| 3 | 1IN+ | Noninverting input of first amplifier - connects to reference or signal source with ultra-low bias current |
| 4 | VCC− | Negative supply rail - must be decoupled locally to suppress ground bounce in dual-supply operation |
| 5 | 2IN+ | Noninverting input of second amplifier - electrically isolated from Channel 1 for independent signal paths |
| 6 | 2IN− | Inverting input of second amplifier - supports differential or inverting configurations without crosstalk |
| 7 | 2OUT | Output of second amplifier - capable of sourcing/sinking ±26 mA short-circuit current |
| 8 | VCC+ | Positive supply rail - common to both amplifiers; requires local 0.1 μF ceramic decoupling |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | <120 pA (typ) - minimizes voltage error across high-impedance sensor bridges and photodiode interfaces |
| Output short-circuit protection | ±26 mA continuous limit - prevents latch-up or damage during accidental output faults |
| EMI/RF filtering | Integrated on-die filters - suppresses 1 GHz interference without external ferrites in EMC-sensitive applications |
| Wide temperature range | –40°C to +125°C operation - qualified for under-hood automotive and industrial motor control environments |
| High CMRR | 105 dB (typ) - rejects common-mode noise in unshielded cables and noisy power domains |

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; C-grade (0°C to 70°C) vs B-grade (–40°C to 85°C); 3–5 mV max offset vs 10 mV max | Lower-cost option for commercial temperature range; not rated for extended industrial ambient | Select when full –40°C to +85°C operation is unnecessary and cost sensitivity outweighs offset tightness |
| OPA2134PA | FET-input, 8 MHz GBW, 20 V/μs slew, 8 nV/√Hz noise - superior AC performance but higher quiescent current (4 mA/ch) | Targeted at premium audio and metrology where noise and bandwidth exceed TL072BCDG4 capability | Choose when 37 nV/√Hz noise or 5.25 MHz GBW is insufficient, and board space allows TO-99 or SOIC-8 alternatives |
Compared with TL072CDR and OPA2134PA, the TL072BCDG4 offers the best balance of industrial temperature rating, low-noise JFET input, and proven reliability in cost-constrained embedded systems - making it ideal for long-lifecycle industrial and energy infrastructure designs.

FAQ
What is the maximum supply voltage for TL072BCDG4?
The TL072BCDG4 supports a total supply voltage range of ±2.25 V to ±20 V (4.5 V to 40 V). Absolute maximum ratings allow up to ±20 V across VCC+ and VCC−, with recommended operating conditions specifying 10 V to 30 V for industrial-grade operation. Exceeding these limits risks permanent damage.
Does TL072BCDG4 have rail-to-rail input capability?
Yes, the TL072BCDG4 features a common-mode input voltage range that includes VCC+, meaning its inputs can operate up to and slightly beyond the positive supply rail. However, the output swing is not rail-to-rail - it typically maintains 105–215 mV headroom from each rail under 10 kΩ load.
Is TL072BCDG4 suitable for audio applications?
Yes, TL072BCDG4 is widely used in professional audio applications including mixer preamps and effects processors. Its 37 nV/√Hz input voltage noise at 1 kHz, 0.00012% THD+N, and 20 V/μs slew rate support high-fidelity signal amplification with minimal coloration or transient distortion.
What is the input offset voltage specification for TL072BCDG4?
The TL072BCDG4 has a typical input offset voltage of ±1 mV, with a maximum of ±4 mV at 25°C and ±5 mV over the full –40°C to +85°C operating range. This B-grade specification reflects tighter initial offset tolerance than the standard C-grade TL072 variants.
Can TL072BCDG4 drive capacitive loads?
Yes, the TL072BCDG4 is characterized to drive capacitive loads up to 300 pF while maintaining stability. For loads exceeding 300 pF, external isolation resistors (e.g., 10–100 Ω in series with the output) are recommended to prevent peaking or oscillation, especially in unity-gain configurations.
