Product details
Overview
TL072HIDDFR from Texas Instruments is a dual, JFET-input operational amplifier optimized for low-noise audio and precision analog signal conditioning. It delivers 20 V/μs slew rate, 1 mV typical input offset voltage, 37 nV/√Hz input voltage noise at 1 kHz, ±2.25 V to ±20 V supply range, and operates across –40°C to +125°C. It is used in pro audio mixers and battery test equipment where high CMRR (105 dB), rail-inclusive common-mode input, and low THD+N (0.00012%) are critical.
For engineers reviewing the TL072HIDDFR datasheet, TL072HIDDFR pinout, TL072HIDDFR application, or TL072HIDDFR equivalent, this page provides verified electrical specs, SOIC-8 pin mapping, thermal performance data, real-world use cases in solar inverters and UPS systems, and two validated alternative op-amps with documented functional trade-offs.
Technical Context
The TL072HIDDFR implements a dual-channel, high-slew-rate JFET-input architecture with integrated EMI/RF filters and 1.5 kV HBM ESD protection. Its input stage supports common-mode voltage up to VCC+, enabling single-supply operation without level-shifting circuitry.
It features low input bias current (±1 pA typ), low offset drift (±2 μV/°C), and wide gain-bandwidth product (5.25 MHz), making it suitable for unity-gain stable configurations in transimpedance amplifiers and active filters requiring minimal DC error accumulation over temperature.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Slew Rate | 20 V/μs - enables clean reproduction of fast-rising audio transients and step responses in control loops without slew-induced distortion. |
| Input Offset Voltage | ±1 mV (typ) - ensures ≤1 mV DC error in precision DC-coupled gain stages, reducing calibration burden in sensor front-ends. |
| Input Voltage Noise | 37 nV/√Hz @ 1 kHz - supports high-fidelity audio preamplification and low-level signal amplification without significant noise floor elevation. |
| Supply Voltage Range | ±2.25 V to ±20 V (or 4.5 V to 40 V) - allows flexible bipolar or single-supply operation in industrial and audio systems with varying rail constraints. |
| Common-Mode Input Range | Includes VCC+ - permits direct sensing of signals referenced to the positive rail, eliminating need for external bias networks in single-supply applications. |
| Quiescent Current | 940 μA per channel (typ) - balances low power consumption with high-speed performance for battery-powered and thermally constrained designs. |
| CMRR | 105 dB (typ) - rejects >99.999% of common-mode interference in noisy environments like motor drive feedback paths. |
Pinout & Package
TL072HIDDFR is housed in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (4.9 mm × 3.9 mm × 1.75 mm height). Pin 1 is marked by a beveled corner or dot; device orientation follows TI's standard top-view labeling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives loads up to 2 kΩ while maintaining 115 mV headroom from positive rail at VS = 40 V. |
| 2 | 1IN– | Inverting input of first amplifier - high-impedance JFET node (ZICM = 6 TΩ || 1 pF) minimizes loading on passive filter networks. |
| 3 | 1IN+ | Noninverting input of first amplifier - supports rail-to-rail common-mode input including VCC+, enabling true single-supply instrumentation. |
| 4 | VCC– | Negative supply rail - must be decoupled locally with ≥0.1 μF ceramic capacitor to suppress PSRR degradation above 10 kHz. |
| 5 | 2IN+ | Noninverting input of second amplifier - electrically isolated from Channel 1; no crosstalk (channel separation = 10 μV/V at DC). |
| 6 | 2IN– | Inverting input of second amplifier - matched to Pin 2 for differential pair stability; supports identical biasing schemes as Channel 1. |
| 7 | 2OUT | Output of second amplifier - short-circuit protected; sinks/sours ±26 mA continuously without latch-up. |
| 8 | VCC+ | Positive supply rail - accepts up to 40 V total supply; internal EMI filtering reduces RF rectification in high-noise switch-mode environments. |
Key Features
| Feature | Design Value |
|---|---|
| Low Input Bias Current | ±1 pA typical - preserves accuracy in high-impedance sensor interfaces (e.g., piezoelectric pickups, pH electrodes) without added guard traces or bias compensation. |
| High ESD Robustness | ±2000 V HBM - eliminates need for external TVS diodes in production test fixtures and field-deployed audio gear handling frequent human contact. |
| Rail-Inclusive Common-Mode Range | VCM extends to VCC+ - simplifies single-supply design in battery test equipment by enabling direct connection of reference voltages to VCC+ without level shifters. |
| Integrated EMI/RF Filters | On-die filtering - suppresses 1 GHz RF interference (EMIRR = 53 dB), preventing audible artifacts in pro audio mixers near wireless transmitters. |
| Wide Temperature Operation | –40°C to +125°C - supports deployment in under-hood automotive battery monitors and outdoor solar string inverters without derating. |

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 | Wider offset (±3 mV max), lower temp range (0°C to 70°C), no integrated EMI filters, 1.4 mA IQ. | Not qualified for automotive or extended-temp industrial use; unsuitable for high-EMI environments like motor drives. | Select when cost is primary constraint and full TL072H performance is not required. |
| OPA2134UA | Lower noise (8 nV/√Hz), higher GBW (8 MHz), ±13 V max supply, no rail-to-rail input, 2.2 mA IQ. | Superior audio SNR but incompatible with 40 V supplies or VCC+-referenced inputs in battery testers. | Choose for ultra-low-noise audio paths where supply rails ≤±13 V and VCC+ input is unnecessary. |
Compared with TL072CDR and OPA2134UA, TL072HIDDFR uniquely combines rail-inclusive input, 125°C operation, integrated EMI filtering, and sub-1 mV offset-making it the only option among the three qualified for harsh-environment solar and UPS applications requiring long-term DC accuracy and noise immunity.

FAQ
What is the maximum supply voltage for TL072HIDDFR?
The TL072HIDDFR supports a total supply voltage (VCC+ to VCC–) of up to 40 V (±20 V). Absolute maximum rating is 42 V for non-NS/PS packages, but recommended operating range is 4.5 V to 40 V. Exceeding 40 V risks permanent damage and violates TI's specified conditions for guaranteed performance.
Does TL072HIDDFR support single-supply operation?
Yes, TL072HIDDFR supports true single-supply operation because its common-mode input voltage range extends to VCC+. When powered from +15 V and GND, both inputs accept signals from 0 V to +15 V. Output swing remains within 115 mV of each rail at light load, enabling direct interfacing with unipolar sensors and ADCs.
Is TL072HIDDFR pin-compatible with older TL072 variants?
Yes, TL072HIDDFR uses the industry-standard SOIC-8 (D) package with identical pinout to TL072CDR, TL072CP, and TL072ACDR. All share Pin 1 = 1OUT, Pin 2 = 1IN–, Pin 3 = 1IN+, Pin 4 = VCC–, Pin 5 = 2IN+, Pin 6 = 2IN–, Pin 7 = 2OUT, Pin 8 = VCC+. No PCB layout changes are needed for drop-in replacement.
What is the typical input bias current of TL072HIDDFR?
The typical input bias current of TL072HIDDFR is ±1 pA at 25°C, with a maximum of ±120 pA over the full –40°C to +125°C range. This ultra-low value results from its JFET input stage and enables high-impedance applications such as photodiode transimpedance amplifiers and electrochemical sensor interfaces without significant DC error.
How does TL072HIDDFR handle EMI in noisy environments?
TL072HIDDFR integrates on-die EMI and RF filters, achieving 53 dB EMI rejection ratio at 1 GHz. Combined with ±2000 V HBM ESD rating and internal input clamping diodes, it maintains signal integrity in proximity to switching power supplies, motor drives, and wireless transceivers-eliminating need for external RF chokes or ferrite beads in pro audio mixer designs.
