Product details
Overview
TSV912HYDT from STMicroelectronics is a high-temperature, rail-to-rail input/output operational amplifier optimized for automotive applications. It delivers 8 MHz gain-bandwidth product, 4.5 V/μs slew rate, and 35 mA output drive at 2.5–5.5 V supply, operating from −40 °C to +150 °C with 1 pA typical input bias current.
For engineers reviewing the TSV912HYDT datasheet, TSV912HYDT pinout, TSV912HYDT application, or TSV912HYDT equivalent, key selection criteria include high-temperature stability, ultra-low input bias current for precision sensor interfaces, rail-to-rail swing in low-voltage battery systems, and AEC-Q100 qualified SO8 packaging for under-hood deployment.
Technical Context
The TSV912HYDT employs a CMOS input stage enabling 1 pA input bias current and rail-to-rail common-mode input range (VCC−0.1 V to VCC+0.1 V). Its unity-gain stable architecture supports wide bandwidth (8 MHz GBW) with 45° phase margin into 100 pF capacitive loads.
It features robust thermal performance (Tj up to 160 °C), latch-up immunity (200 mA), and ESD protection ≥5 kV HBM - all validated across −40 °C to +150 °C ambient operation per AEC-Q100 Grade 0 requirements.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz at 25 °C - enables stable closed-loop operation up to ~7.2 MHz in unity-gain configuration |
| Slew rate | 4.5 V/μs - supports fast transient response in active filtering and signal conditioning |
| Input bias current | 1 pA typ at 25 °C - minimizes voltage error in high-impedance sensor front-ends (e.g., thermopiles, pH electrodes) |
| Supply voltage range | 2.5 V to 5.5 V - compatible with 3.3 V and 5 V automotive microcontroller domains and battery-supplied modules |
| Operating temperature | −40 °C to +150 °C - certified for engine control units, transmission sensors, and exhaust gas recirculation systems |
| Output drive | ±35 mA - drives 600 Ω loads while maintaining rail-to-rail swing, suitable for analog output stages |
| Input offset voltage | 4.5 mV typ at 25 °C - low drift (2 μV/°C up to 125 °C) ensures stable DC accuracy over temperature |
Pinout & Package
TSV912HYDT is housed in an SO8 (Small Outline 8-pin) package per JEDEC MS-012, with moisture sensitivity level 1 (MSL1) and ECOPACK® environmental compliance. Pin 1 is marked by a beveled corner or dot.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| Inverting input (−) | Differential input node | Accepts feedback network connection; referenced to non-inverting input for precise gain setting |
| Non-inverting input (+) | Differential input node | Connects to reference voltage or sensor signal; rail-to-rail common-mode range supports 0 V to VCC |
| VCC− (GND) | Negative supply terminal | Ground reference for single-supply operation; must be decoupled with 10 nF capacitor near pin |
| Output | Amplified signal source | Delivers rail-to-rail swing and ±35 mA drive; stable into 100 pF without external compensation |
| VCC+ | Positive supply terminal | Accepts 2.5–5.5 V; decoupling required to maintain PSRR >70 dB and noise immunity |
| NC | No connect | Internally unconnected; must remain floating per datasheet - not for grounding or routing |
| NC | No connect | Internally unconnected; no electrical function - avoid PCB trace or solder mask exposure |
| NC | No connect | Internally unconnected; unused pin per SO8 pinout - no thermal or shielding benefit |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V systems - critical for maximizing ADC resolution in low-voltage sensor nodes |
| High-temperature operation (−40 °C to +150 °C) | Validated per AEC-Q100 Grade 0 - eliminates derating for under-hood placement in engine management and brake control modules |
| Ultra-low input bias current (1 pA typ) | Reduces leakage-induced offset in high-Z transducer interfaces (e.g., piezoresistive pressure sensors) without external guarding |
| Unity-gain stable with 45° phase margin | Supports direct use in voltage follower, active filter, and buffer configurations without external compensation components |
| ESD protection ≥5 kV HBM | Ensures robustness during automotive assembly and field service - exceeds ISO 10605 requirements for component-level ESD immunity |
Applications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-temperature op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912IDT | Standard temperature grade (−40 °C to +125 °C); identical electrical specs except max operating temperature | Not qualified for under-hood locations exceeding 125 °C ambient (e.g., near turbochargers or exhaust manifolds) | Select when cost-sensitive industrial or cabin-mounted applications do not require 150 °C operation |
| LM7332MME/NOPB | Wider supply range (2.7–36 V), higher quiescent current (2.5 mA), no AEC-Q100 qualification | Lacks automotive qualification and high-temp validation; requires external ESD protection for vehicle integration | Use only in non-automotive, wide-VCC industrial systems where 150 °C operation is unnecessary |
Compared with TSV912IDT and LM7332MME/NOPB, the TSV912HYDT uniquely combines AEC-Q100 Grade 0 qualification, 150 °C operation, and 1 pA input bias - making it irreplaceable for precision analog signal chains in harsh automotive environments.

FAQ
Is TSV912HYDT pin-compatible with standard SO8 op-amps like LM358?
No - TSV912HYDT uses a non-standard SO8 pinout with three NC pins (pins 6–8). Unlike LM358 (which places VCC− on pin 4 and VCC+ on pin 8), TSV912HYDT assigns VCC− to pin 3 and VCC+ to pin 5. Direct replacement requires PCB redesign and layout verification per Figure 1 in DocID17688 Rev 2.
What decoupling capacitance is required for stable operation?
A minimum 10 nF ceramic capacitor must be placed between VCC+ (pin 5) and VCC− (pin 3), located within 2 mm of the SO8 package. This value is validated for PSRR >70 dB and phase margin stability across −40 °C to +150 °C; larger values (>100 nF) may degrade transient response due to increased loop delay.
Can TSV912HYDT drive capacitive loads greater than 100 pF?
Yes - but only with external stabilization. The device remains stable into 100 pF without compensation. For loads >100 pF, a series resistor (2–10 Ω, per Figure 19) must be added between the output (pin 4) and load to restore phase margin above 45°; bench validation is mandatory for each target load value.
Does TSV912HYDT support dual-supply operation?
Yes - though optimized for single-supply use. With VCC+ = +2.5 V and VCC− = −2.5 V (total 5 V), it maintains rail-to-rail input (−2.6 V to +2.6 V) and output (−2.5 V to +2.5 V), provided common-mode voltage stays within specified limits and decoupling is symmetric. Absolute maximum ratings limit total supply to 6 V.
