Product details
Overview
TL072ACDRE4 from Texas Instruments is a dual JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 37 nV/√Hz input voltage noise at 1 kHz, 20 V/μs slew rate, ±15 V (±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 TL072ACDRE4 datasheet, TL072ACDRE4 pinout, TL072ACDRE4 application, or TL072ACDRE4 equivalent, this page provides verified electrical specifications, SOIC-8 package layout, real-world use cases in solar inverters and battery test equipment, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TL072ACDRE4 implements a dual-channel, high-slew-rate JFET-input architecture with rail-to-rail common-mode input range extending to VCC+, integrated EMI/RF filtering, and output short-circuit protection. Its FET input stage enables ultra-low input bias current (1 pA typ) and low 1/f noise, making it suitable for high-impedance source interfacing.
It operates across –40°C to +85°C (commercial grade), supports supply voltages from ±2.25 V to ±20 V, and maintains 100 dB CMRR and 125 dB open-loop gain under full-load conditions - ensuring stable closed-loop performance in DC-coupled instrumentation and active filter designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage | ±2.25 V to ±20 V - supports bipolar supplies down to ±2.25 V for low-voltage precision sensing without rail compression. |
| Input Offset Voltage | 1 mV (typ) - enables accurate DC amplification in strain gauge or thermocouple interfaces with <0.1% initial error. |
| Slew Rate | 20 V/μs - sustains clean 100 kHz full-power bandwidth at ±10 V output swing, critical for audio line drivers. |
| Input Voltage Noise | 37 nV/√Hz @ 1 kHz - preserves SNR in microphone preamps and low-level sensor signal chains. |
| Common-Mode Input Range | Includes VCC+ - allows direct interface to signals referenced to positive rail, e.g., current-sense shunt monitoring. |
| Quiescent Current | 940 μA per channel - balances low power consumption with high-speed performance for battery-powered test gear. |
| CMRR | 100 dB (min) - rejects common-mode interference in noisy industrial environments like motor drive feedback loops. |
Pinout & Package
TL072ACDRE4 is housed in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm, 1.27 mm pitch). Pin 1 is marked by a beveled corner or dot; thermal pad is not present.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives external load or next-stage input; capable of ±12 V swing into 10 kΩ. |
| 2 | 1IN– | Inverting input of first amplifier - accepts feedback network or inverted signal path; high-impedance (1 TΩ). |
| 3 | 1IN+ | Noninverting input of first amplifier - connects to reference or high-Z sensor; common-mode range includes VCC+. |
| 4 | VCC– | Negative supply rail - must be decoupled with ≥0.1 μF ceramic capacitor near pin. |
| 5 | 2IN+ | Noninverting input of second amplifier - independent channel; identical specs to Channel 1. |
| 6 | 2IN– | Inverting input of second amplifier - used for differential gain stages or active filters. |
| 7 | 2OUT | Output of second amplifier - fully isolated from Channel 1; supports separate gain/phase tuning. |
| 8 | VCC+ | Positive supply rail - requires local 0.1 μF ceramic bypass to minimize supply-induced distortion. |
Key Features
| Feature | Design Value |
|---|---|
| Low input bias current | 1 pA typical - eliminates significant voltage error when driving high-value feedback resistors (>1 MΩ) in integrators. |
| Output short-circuit protection | ±26 mA continuous limit - prevents latch-up or destruction during accidental output shorts in lab equipment. |
| Low THD+N | 0.003% (typ) at 1 kHz - ensures transparent audio signal reproduction in mixing console summing amps. |
| Wide supply range | ±2.25 V to ±20 V - accommodates both portable battery-powered designs and industrial ±15 V systems without redesign. |
| EMI/RF rejection | 53 dB at 1 GHz - suppresses cellular and switching regulator noise in embedded measurement modules. |
Applications

IC Role / Device Role / Timing Role: Dual-channel preamplifier with independent gain control per channel; no timing function. Use Value: 37 nV/√Hz noise floor preserves dynamic range; ±20 V supply headroom avoids clipping on transient peaks. | Use Scenario: Isolating and scaling DC bus voltage and string current measurements in photovoltaic array monitoring units. IC Role / Device Role / Timing Role: Precision differential amplifier for shunt-based current sensing and high-side voltage divider buffering. Use Value: Rail-inclusive common-mode input handles >600 V string voltages via resistive dividers; 100 dB CMRR rejects inverter switching noise. |

Use Value: 20 V/μs slew rate tracks fast-changing PWM-modulated currents; EMI filtering reduces false triggering in noisy EMI environments. |
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; commercial temperature range (0°C to 70°C); 3 mV max offset vs. 10 mV for TL072ACDRE4. | Lower-cost option for non-critical consumer audio; lacks A-grade offset spec for precision sensor front-ends. | Select TL072CDR only if 3 mV offset and 0°C–70°C operation meet system requirements. |
| OPA2134PA | Higher cost; 8 V/μs slew rate; 8 nV/√Hz noise; unity-gain stable; SO-8 package. | Better suited for ultra-low-noise audio DAC output stages where 37 nV/√Hz is insufficient. | Choose OPA2134PA when noise performance dominates over slew rate and cost constraints. |
Compared with TL072CDR, TL072ACDRE4 offers tighter offset (1 mV vs. 3 mV typ) and extended temperature range (–40°C to +85°C), while OPA2134PA trades slew rate for significantly lower noise - making TL072ACDRE4 optimal for cost-sensitive, wide-temp, medium-bandwidth precision analog paths.

FAQ
What is the maximum supply voltage rating for TL072ACDRE4?
The absolute maximum supply voltage for TL072ACDRE4 is ±20 V (40 V total), with recommended operating range from ±2.25 V to ±20 V. Exceeding ±20 V risks permanent damage, and operation below ±2.25 V may degrade slew rate and output swing. Always observe the 0.3 V diode clamp margin relative to rails per the datasheet's Absolute Maximum Ratings table.
Does TL072ACDRE4 support rail-to-rail input or output?
TL072ACDRE4 supports rail-to-rail common-mode input - its input range extends to VCC+ - but does not provide rail-to-rail output swing. Typical output swing is within 115 mV of VCC+ and 105 mV of VCC– under 10 kΩ load. For true rail-to-rail I/O, consider modern alternatives like TLV2462 or OPA2313.
Is TL072ACDRE4 pin-compatible with other TL072 variants in SOIC-8?
Yes, TL072ACDRE4 is pin-compatible with all TL072x devices in the D (SOIC-8) package, including TL072CDR, TL072IDR, and TL072CP. Pin functions - 1OUT, 1IN–, 1IN+, VCC–, 2IN+, 2IN–, 2OUT, VCC+ - are identical across these variants; only electrical specs and temperature grades differ.
What is the input bias current specification for TL072ACDRE4 at 85°C?
At TA = +85°C, TL072ACDRE4 exhibits ≤5 nA maximum input bias current, per Section 5.8 of the datasheet. This is higher than the 1 pA typical value at 25°C but remains orders of magnitude lower than bipolar-input op-amps - preserving accuracy in high-impedance sensor interfaces even at elevated temperatures.
Can TL072ACDRE4 drive capacitive loads up to 300 pF stably?
Yes, TL072ACDRE4 is characterized to drive up to 300 pF capacitive load without oscillation, as confirmed in Section 5.7 (CLOAD = 300 pF). However, for loads >100 pF, adding a small series resistor (10–50 Ω) between output and load improves phase margin and settling behavior in precision applications like active filters.
