Product details
Overview
TL072HIDR 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 rail-to-rail common-mode input including VCC+. It is widely deployed in pro audio mixers and battery test equipment where FET-input stability and low distortion are critical.
For engineers reviewing the TL072HIDR datasheet, TL072HIDR pinout, TL072HIDR application, or TL072HIDR equivalent, this page provides verified specifications, SOIC-8 package terminal mapping, real-world use cases in high-fidelity signal chains, and two validated alternative op-amps with documented functional trade-offs for design flexibility.
Technical Context
The TL072HIDR 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 features ultra-low bias current (±1 pA typ) and wide common-mode range extending to VCC+, enabling direct interfacing with high-impedance sensors and single-supply configurations.
It operates across –40°C to +125°C with guaranteed 125 dB open-loop gain, 5.25 MHz gain-bandwidth product, and 0.00012% THD+N at 1 kHz - characteristics confirmed for the TL07xH die revision per Section 5.7 of the official datasheet.
Key Specifications

Pinout & Package
TL072HIDR is supplied in an 8-pin SOIC (D) package with standard JEDEC MS-012AC footprint (5.3 mm × 6.2 mm), surface-mount compatible, and RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | 1OUT | Output of first amplifier - drives external load or next stage with rail-swing capability |
| 2 | 1IN– | Inverting input of first amplifier - accepts feedback network or inverted signal path |
| 3 | 1IN+ | Noninverting input of first amplifier - connects to reference, sensor, or signal source |
| 4 | VCC– | Negative power supply rail - must be decoupled locally to minimize noise coupling |
| 5 | 2IN+ | Noninverting input of second amplifier - independent signal path for dual-channel operation |
| 6 | 2IN– | Inverting input of second amplifier - supports differential or inverting configuration |
| 7 | 2OUT | Output of second amplifier - fully isolated output channel with identical specs to Pin 1 |
| 8 | VCC+ | Positive power supply rail - supplies both amplifiers; common to all internal circuitry |
Key Features
| Feature | Design Value |

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 | Higher input offset (±3 mV typ), wider temp range (0°C to 70°C), no integrated EMI filter | Cost-sensitive consumer audio; not rated for extended temperature or EMI-heavy environments | Select when budget constraints outweigh need for low-offset or industrial-grade EMI immunity |
| OPA2134PA | Lower noise (8 nV/√Hz), higher quiescent current (4 mA/ch), rail-to-rail output, no short-circuit protection | Ultra-low-noise studio preamps; requires external current limiting and careful layout for stability | Select when ultimate audio fidelity is required and board space allows for added protection circuitry |
Compared with TL072CDR, TL072HIDR offers tighter offset, lower noise, and built-in EMI filtering - making it preferable for industrial and pro-audio designs. Compared with OPA2134PA, TL072HIDR trades some noise performance for robustness, lower power, and integrated protection - ideal for embedded systems where reliability trumps marginal SNR gains.

FAQ
What is the maximum supply voltage for TL072HIDR?
The TL072HIDR supports a total supply voltage (VCC+ to VCC−) of up to 40 V (±20 V). Absolute maximum ratings specify 36 V for NS and PS packages and 42 V for all other variants, but recommended operating conditions limit continuous use to 40 V to ensure long-term reliability and specified performance across temperature.
Does TL072HIDR have rail-to-rail output capability?
No, TL072HIDR does not provide rail-to-rail output swing. Its typical output voltage swing is within 115–210 mV of the positive rail and 105–215 mV of the negative rail under 10 kΩ load at ±20 V supply. This limitation is inherent to its JFET-output stage and must be accounted for in headroom-critical designs.
Is TL072HIDR pin-compatible with older TL072 variants?
Yes, TL072HIDR is pin-compatible with TL072CDR, TL072ACDR, and TL072BCDR in the same SOIC-8 (D) package. All share identical pinout, footprint, and basic electrical interface - though TL072HIDR improves on offset, noise, ESD rating (1.5 kV HBM), and operating temperature range (–40°C to +125°C).
What is the input bias current specification for TL072HIDR at 125°C?
Per Section 5.7 of the datasheet, the input bias current for TL072HIDR is specified at ±5 nA maximum over the full –40°C to +125°C temperature range. This elevated value reflects JFET gate leakage increase at high temperature and remains significantly lower than bipolar-input op-amps.
Can TL072HIDR drive capacitive loads directly?
TL072HIDR is characterized to drive up to 300 pF capacitive load stably, as confirmed by small-signal overshoot testing in Figure 5-23 and 5-24. For loads exceeding 300 pF, external isolation resistance (e.g., 10–100 Ω in series with output) is recommended to maintain phase margin and prevent oscillation.
