Product details
Overview
TSV911AIYDT from STMicroelectronics is a single-channel, rail-to-rail input/output operational amplifier optimized for automotive-grade applications. It operates from 2.5 V to 5.5 V, delivers 8 MHz gain-bandwidth product, consumes only 820 µA typical supply current, and features 1.5 mV max input offset voltage (A grade) and 1 pA typical input bias current - enabling precision signal conditioning in battery-constrained automotive sensor interfaces.
For engineers reviewing the TSV911AIYDT datasheet, TSV911AIYDT pinout, TSV911AIYDT application, or TSV911AIYDT equivalent, this device is selected for low-voltage, low-power analog front-ends requiring rail-to-rail swing, high output drive (±35 mA), and AEC-Q100 qualified reliability in engine control units, body electronics, and ADAS sensor signal chains.
Technical Context
The TSV911AIYDT employs a CMOS input stage delivering ultra-low input bias current (1 pA typ.) and rail-to-rail common-mode input range (VCC− − 0.1 V to VCC+ + 0.1 V), supporting direct interfacing with high-impedance sensors. Its unity-gain stable architecture achieves 4.5 V/µs slew rate and 45° phase margin into 100 pF capacitive loads without external compensation.
It integrates ESD protection ≥5 kV (HBM), latch-up immunity up to 200 mA, and operates across −40 °C to +125 °C - meeting automotive ambient and transient requirements. The SO-8 package variant uses standard pinout (IN−, IN+, VCC−, OUT, VCC+, NC, NC, NC) with internal NC pins reserved for dual/quad variants.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - supports stable closed-loop operation up to ~1 MHz at unity gain for anti-aliasing filters and sensor amplification. |
| Supply current (typ.) | 820 µA - enables multi-year battery life in always-on automotive modules like door control or occupancy detection. |
| Input offset voltage (max) | 1.5 mV (A grade, 25 °C) - ensures ≤0.3% error in 0–5 V sensor output scaling without trimming. |
| Input bias current (typ.) | 1 pA - prevents significant voltage drop across >10 MΩ source impedances (e.g., piezoresistive or pH sensors). |
| Output drive (sourcing/sinking) | 35 mA / 32 mA - directly drives 100 Ω loads or multiple CMOS inputs without buffer stages. |
| Common-mode input range | VCC− − 0.1 V to VCC+ + 0.1 V - accepts signals spanning full supply rail, critical for single-supply industrial transducers. |
| ESD HBM rating | ≥5 kV - withstands handling and board-level electrostatic discharge in automotive assembly environments. |
Pinout & Package
TSV911AIYDT 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−) | High-impedance node for feedback network connection; accepts rail-to-rail common-mode voltages. |
| 2 | Non-inverting input (IN+) | Direct interface point for sensor outputs or reference voltages; 1 pA bias current minimizes loading error. |
| 3 | VCC− (ground) | Power return path; must be decoupled with 10 nF capacitor placed <1 mm from pin per layout guidelines. |
| 4 | Output (OUT) | Capable of ±35 mA drive into resistive loads; stable with ≤100 pF capacitive loads in unity-gain follower configuration. |
| 5 | VCC+ (supply) | Accepts 2.5–5.5 V DC; supply rejection ratio ≥70 dB ensures immunity to power rail noise in noisy automotive domains. |
| 6–8 | No connect (NC) | Internally unconnected; may be tied to VCC− or left floating - no electrical function or thermal impact. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization in 3.3 V or 5 V single-supply systems without level-shifting circuitry. |
| AEC-Q100 Grade 1 qualified | Validated for −40 °C to +125 °C operation with extended lifetime testing - suitable for under-hood and cabin ECUs. |
| Unity-gain stable | Eliminates need for external compensation components in buffer, gain, or active filter configurations. |
| Low input offset drift | 5 µV/°C - limits temperature-induced error to <0.6 mV over full automotive temperature range (165 °C span). |
| High output current | 35 mA sourcing capability allows direct driving of LED indicators, small solenoids, or ADC reference buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV911IDT | Industrial-grade version (−40 °C to +125 °C), same SO-8 pinout and electrical specs, but not AEC-Q100 qualified. | Lacks automotive qualification; unsuitable for safety-critical or under-hood deployments requiring AEC-Q100 documentation. | Select when cost sensitivity outweighs automotive compliance needs and ambient temperature remains within spec. |
| TSV991AIYDT | Higher-speed variant (20 MHz GBP, 10 V/µs SR), same AEC-Q100 Grade 1, SO-8 package, and rail-to-rail I/O. | Consumes 1.4 mA vs. 0.82 mA - trades power efficiency for bandwidth in high-frequency sensor or communication circuits. | Choose when system requires >8 MHz closed-loop bandwidth or faster transient response in ADAS timing-critical paths. |
Compared with TSV911IDT, the TSV911AIYDT adds AEC-Q100 qualification and tighter offset voltage (1.5 mV vs. 4.5 mV max), while TSV991AIYDT doubles bandwidth at higher quiescent current - making TSV911AIYDT optimal for cost-sensitive, precision, low-power automotive analog sensing where speed is secondary.

FAQ
What is the maximum capacitive load the TSV911AIYDT can drive without oscillation?
The TSV911AIYDT is stable driving up to 100 pF capacitive loads in unity-gain follower configuration, as verified by phase margin ≥45° at 5 V supply. For loads exceeding 100 pF, ST recommends adding a 10–100 Ω series resistor between the output and load to restore stability - confirmed via bench testing and simulation using ST's published macromodel.
Does the TSV911AIYDT require external compensation for unity-gain operation?
No. The TSV911AIYDT is internally compensated for unity-gain stability across its full operating voltage (2.5–5.5 V) and temperature (−40 °C to +125 °C) range. No external capacitors or resistors are needed for stable operation in gain = 1, inverting, or non-inverting configurations per datasheet Figure 8–9 and Table 3–5 AC performance data.
How is the exposed pad on the SO-8 package used in the TSV911AIYDT?
The SO-8 package for TSV911AIYDT does not include an exposed thermal pad - unlike DFN8 variants. All mechanical data in DS4899 Rev 13 confirm SO-8 has no thermal pad; the "exposed pad" note applies only to DFN8 2×2 packages. SO-8 thermal dissipation relies on standard PCB copper area connected to pins 3 (VCC−) and 5 (VCC+).
Can the TSV911AIYDT operate from a 2.3 V supply?
No. The absolute minimum supply voltage is 2.5 V per Table 2 (Operating Conditions), and guaranteed operation starts at 2.5 V across −40 °C to +125 °C. At 2.3 V, parameters like GBP, slew rate, and output drive degrade outside specification - ST does not characterize or guarantee functionality below 2.5 V, even if the device may power on.
