Product details
Overview
TL072BIYDT from STMicroelectronics is a high-speed, low-noise JFET-input dual operational amplifier rated for automotive-grade operation (−40 °C to +125 °C), featuring 16 V/µs slew rate, 15 nV/√Hz input voltage noise, and ±11 V input common-mode range with ±15 V supply. It delivers 0.01 % THD at 1 kHz and supports rail-to-rail output swing up to ±12 V into 2 kΩ - used in precision audio preamplifiers, sensor signal conditioning, and automotive cabin control analog front-ends.
For engineers reviewing the TL072BIYDT datasheet, TL072BIYDT pinout, TL072BIYDT application, or TL072BIYDT equivalent, this page provides verified technical context, SO8 package mapping, real-world use scenarios, and validated alternatives for AEC-Q100-compliant analog signal chain design.
Technical Context
The TL072BIYDT integrates two matched JFET-input op-amp channels on a single monolithic die, using high-voltage JFETs for input stage and bipolar transistors for output stage. Its internal frequency compensation ensures unity-gain stability without external components.
It operates over ±6 V to ±18 V supply range, supports differential input voltages up to ±30 V, and maintains latch-up-free behavior under transient stress - critical for automotive subsystems exposed to load dump or reverse battery conditions.
Key Specifications

|---|---|
| Slew Rate | 16 V/µs typical - enables clean amplification of fast-slewing audio or sensor signals without distortion |
| Input Voltage Noise | 15 nV/√Hz at 1 kHz - preserves SNR in low-level microphone or thermocouple amplification |
| Input Bias Current | 20 pA typical at 25 °C - minimizes DC error in high-impedance transducer interfaces |
| Common-Mode Range | ±11 V with ±15 V supply - allows direct sensing of signals referenced to non-ground potentials |
| THD + N | 0.01 % at 1 kHz, 2 Vpp - meets fidelity requirements for automotive infotainment line drivers |

| 3 | Non-inverting Input 1 | High-Z input accepting signals within ±11 V common-mode range |
| 4 | VCC− | Negative supply rail; must be connected to system ground or negative bias |
| 5 | Non-inverting Input 2 | Second op-amp's positive input; electrically isolated but thermally coupled to Channel 1 |
| 6 | Inverting Input 2 | Second channel's feedback node; matches Channel 1's bias and noise specs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual JFET op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TL072CDT | Commercial grade (0 °C to +70 °C); same electrical specs but no AEC-Q100 validation | Not qualified for under-hood or cabin control modules requiring extended temperature operation | Select only for cost-sensitive non-automotive applications with ambient-limited environments |
| OPA2134UA | Lower noise (8 nV/√Hz), higher GBP (8 MHz), but higher supply current (4 mA/ch) and no automotive qualification | Preferred for premium audio where SNR outweighs power and qualification constraints | Choose when THD < 0.001 % and wider bandwidth are required, and AEC-Q100 is not mandated |
Compared with TL072CDT and OPA2134UA, TL072BIYDT uniquely combines AEC-Q100 Grade 1 compliance, JFET-input low-noise performance, and robust ±30 V differential input tolerance - making it the only option qualified for safety-relevant analog signal chains in modern vehicle ECUs.

FAQ
Is TL072BIYDT pin-compatible with standard TL072 variants?
Yes - TL072BIYDT uses the same SO8 footprint and pinout as TL072IDT, TL072CDT, and all TL072x variants. The 'Y' suffix denotes AEC-Q100 qualification and enhanced screening, not mechanical or electrical reconfiguration. No PCB redesign is needed when upgrading from commercial to automotive-grade versions.
What is the maximum safe supply voltage for TL072BIYDT?
The absolute maximum supply voltage is ±18 V (36 V total), but continuous operation above ±15 V requires thermal derating due to increased power dissipation. At +125 °C ambient, the recommended maximum is ±13 V to stay within the 500 mW SO8 package power limit and maintain reliability per AEC-Q100 stress guidelines.
Does TL072BIYDT support single-supply operation?
Yes - it functions with single supplies as low as +6 V, provided the input common-mode range (−12 V to +15 V relative to VCC−) and output swing (≥10 V peak-to-peak into 2 kΩ) are respected. For true rail-to-rail input/output, a dedicated RRIO op-amp is required; TL072BIYDT retains JFET-input headroom limitations.
How does TL072BIYDT differ from TL072AIYDT and TL072IYDT?
TL072BIYDT has the tightest input offset voltage spec: 1–3 mV (25 °C), versus 3–6 mV for TL072AIYDT and 3–10 mV for TL072IYDT. All three share identical packaging, temperature rating, noise, slew rate, and AEC-Q100 qualification - only the initial Vio binning differs, enabling higher-accuracy designs without layout changes.
