Product details
Overview
TSV911IYDT from STMicroelectronics is a single-channel rail-to-rail input/output operational amplifier optimized for automotive-grade applications, operating from 2.5 V to 5.5 V with 8 MHz gain-bandwidth product, 4.5 V/µs slew rate, and ultra-low 1 pA typical input bias current. It delivers 35 mA output drive capability and achieves 1.5 mV max input offset voltage (A grade) across –40 °C to 125 °C, making it suitable for precision sensor interfaces in engine control units.
For engineers reviewing the TSV911IYDT datasheet, TSV911IYDT pinout, TSV911IYDT application, or TSV911IYDT equivalent, key selection considerations include its AEC-Q100 qualified SO-8 package, rail-to-rail operation at low supply voltage, high CMRR (82 dB), low noise (21 nV/√Hz @ 10 kHz), and unity-gain stability with capacitive load drive up to 100 pF.
Technical Context
The TSV911IYDT employs a CMOS input stage enabling 1 pA typical input bias current and rail-to-rail common-mode input range (VCC– – 0.1 V to VCC+ + 0.1 V), supporting direct interfacing with low-output-impedance sensors. Its internal compensation ensures unity-gain stability without external components while maintaining 45° phase margin with 100 pF capacitive load.
It features a robust output stage delivering ±32 mA sink/source current into 600 Ω loads, with output swing within 40 mV of rails at 10 kΩ and 150 mV at 600 Ω. The device exhibits 86 dB supply voltage rejection ratio (SVR) and 82 dB common-mode rejection ratio (CMRR) at 5 V supply, critical for noisy automotive power domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable closed-loop operation up to ~1 MHz in unity-gain buffer or non-inverting configurations. |
| Slew rate | 4.5 V/µs - supports clean 100 kHz sine-wave output at 2 Vpp without distortion in active filtering. |
| Input offset voltage (max) | 1.5 mV (A grade, 25 °C) - limits DC error to ≤0.3% of full-scale in 0.5 V reference amplification. |
| Supply current (typ) | 820 µA - allows continuous operation for >1 year on a 200 mAh coin cell in always-on battery monitoring. |
| Common-mode rejection | 82 dB (at 5 V) - rejects ≥12.6 V of common-mode noise while amplifying 100 mV differential signal. |
| Output drive | ±35 mA - directly drives 10-bit SAR ADC reference buffers or LED indicators without external transistors. |
| ESD protection | ≥5 kV HBM - survives handling and board-level ESD events per ISO 10605 in automotive assembly. |
Pinout & Package
TSV911IYDT is supplied in an automotive-qualified SO-8 package (ECOPACK® compliant), with exposed pad electrically unconnected and configurable as ground or left floating per layout requirements.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (IN–) | Differential node for feedback network connection; accepts common-mode voltages down to VCC– – 0.1 V. |
| 2 | Non-inverting input (IN+) | Sensor or reference signal input; rail-to-rail common-mode range enables direct connection to resistive divider outputs. |
| 3 | VCC– (ground) | Power return path; must be decoupled with 10 nF capacitor placed <1 mm from pin per layout guidelines. |
| 4 | NC | No internal connection; may be grounded or left unconnected to reduce parasitic coupling. |
| 5 | Output (OUT) | Capable of sourcing/sinking 32 mA while maintaining rail-to-rail swing; stable with 100 pF load. |
| 6 | NC | No internal connection; no routing required; avoid stub traces to minimize EMI susceptibility. |
| 7 | VCC+ (supply) | Accepts 2.5–5.5 V; requires local 10 nF ceramic decoupling; SVR of 86 dB suppresses ripple-induced errors. |
| 8 | NC | No internal connection; not used in single-amplifier configuration; leave unconnected per datasheet. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V systems-output swings within 40 mV of rails at light load. |
| Automotive qualification | AEC-Q100 Grade 1 (–40 °C to 125 °C) with advanced screening per AEC-Q001/Q002-validates reliability for under-hood use. |
| Low input bias current | 1 pA typical eliminates significant voltage error across high-impedance pH or thermistor sensor networks (>10 MΩ). |
| Unity-gain stable | Operates without external compensation in buffer, integrator, or active filter topologies-reduces BOM count. |
| High output current | 35 mA drive capability supports direct interface to analog multiplexers, DAC buffers, or low-side current sense shunts. |
Applications
| Engine Control Unit Sensor Interface | Automotive Cabin Temperature Monitoring |

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911IDT | Industrial-grade (–40 °C to 125 °C), same electrical specs but not AEC-Q100 qualified. | Lacks automotive qualification testing-unsuitable for safety-critical ECU modules requiring PPAP documentation. | Select when cost sensitivity outweighs automotive compliance requirements and ambient temperature remains within spec. |
| TSV991IYDT | Higher 20 MHz GBW, 10 V/µs slew rate, but higher 1.4 mA ICC and reduced CMRR (75 dB). | Better for wideband signal conditioning (e.g., radar front-end), less optimal for DC-stable sensor buffering. | Choose only when bandwidth >10 MHz is mandatory and supply current budget allows +70% increase. |
Compared with TSV911IDT, the TSV911IYDT adds AEC-Q100 validation and tighter Vos drift control, while TSV991IYDT trades precision and power efficiency for speed-making TSV911IYDT the optimal choice for automotive sensor signal chains demanding accuracy, low power, and qualification assurance.

FAQ
What is the maximum capacitive load the TSV911IYDT can drive without external compensation?
The TSV911IYDT is unity-gain stable and can drive up to 100 pF capacitive load directly in voltage-follower configuration without oscillation, as verified by 45° phase margin measurements at 5 V supply. For loads exceeding 100 pF, a series resistor (e.g., 10–100 Ω) between output and load is recommended to restore stability.
Does the exposed pad on the SO-8 package require PCB connection?
No-the exposed pad of the TSV911IYDT's SO-8 package is not internally connected. Per STMicroelectronics' datasheet (DS4899 Rev 13, page 17), it may be tied to VCC– (ground) for improved thermal performance or left floating; neither choice affects electrical functionality, but grounding improves heat dissipation by ~15%.
How does the TSV911IYDT's input offset voltage compare across temperature?
At 25 °C, the A-grade TSV911IYDT has a maximum input offset voltage of 1.5 mV; this increases to 3 mV over the full –40 °C to 125 °C operating range. Its 5 µV/°C drift coefficient ensures predictable, linear offset variation-critical for calibration algorithms in engine temperature sensing.
Can the TSV911IYDT operate from a single 2.5 V supply in rail-to-rail mode?
Yes-the TSV911IYDT is fully specified for 2.5 V to 5.5 V single-supply operation. At 2.5 V, its input common-mode range extends from –0.1 V to +2.6 V, and output swings within 40 mV of both rails under 10 kΩ load, enabling full utilization of 2.5 V ADC reference ranges without level-shifting circuitry.
