Product details
Overview
TSV912IYST from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in MiniSO8 package, designed for precision signal conditioning in automotive-grade systems. It delivers 8 MHz gain-bandwidth, 4.5 V/µs slew rate, 1.5 mV max input offset voltage (A grade), 1 pA typical input bias current, and operates from 2.5 V to 5.5 V supply. Used in sensor front-ends and battery-powered ADAS modules.
For engineers reviewing the TSV912IYST datasheet, TSV912IYST pinout, TSV912IYST application, or TSV912IYST equivalent, key selection criteria include its AEC-Q100 qualified MiniSO8 footprint, rail-to-rail swing at low supply, ultra-low input bias for high-impedance sources, and guaranteed 1.5 mV max VOS over temperature for medical-grade signal chains.
Technical Context
The TSV912IYST implements a CMOS input stage enabling 1 pA typical input bias current and rail-to-rail input common-mode range (VCC– – 0.1 V to VCC+ + 0.1 V). Its unity-gain-stable architecture supports stable operation with capacitive loads up to 100 pF without external compensation.
It features internal ESD protection ≥5 kV HBM and latch-up immunity of 200 mA, meeting automotive reliability requirements. The device maintains 75 dB min CMRR and 86 dB min SVRR across 2.5–5 V supply, ensuring robust performance in noisy vehicle electrical environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable closed-loop operation up to ~1 MHz with moderate gain in sensor amplification stages |
| Input offset voltage (max) | 1.5 mV - ensures ≤0.3% error in 0.5 V full-scale medical or automotive sensor outputs |
| Supply current per channel | 1.1 mA max - supports >10-year battery life in always-on telematics nodes at 3.3 V |
| Slew rate | 4.5 V/µs - handles 10 kHz sine waves at 10 Vpp without distortion in active filter designs |
| Input bias current (typ) | 1 pA - preserves signal integrity from high-Z pH or piezoelectric sensors without loading |
| Common-mode rejection | 75 dB min - rejects >5,600:1 of coupled noise on differential sensor lines |
| Operating temperature | −40 °C to +125 °C - qualified for under-hood and cabin-mounted automotive ECUs |
Pinout & Package
TSV912IYST is housed in a 8-pin MiniSO8 package (3.0 mm × 3.0 mm, 0.65 mm pitch), AEC-Q100 qualified, with exposed pad electrically unconnected and configurable as ground or left floating.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplified output of Channel 1; capable of ±35 mA drive into resistive loads |
| 2 | IN1− | Inverting input of Channel 1; rail-to-rail common-mode range supports single-supply sensor interfacing |
| 3 | IN1+ | Non-inverting input of Channel 1; 1 pA bias current avoids loading high-impedance transducers |
| 4 | VCC+ | Positive supply rail (2.5–5.5 V); requires local 10 nF decoupling per ST layout guidelines |
| 5 | VCC− | Negative supply rail (typically GND); shared return path for both channels |
| 6 | OUT2 | Amplified output of Channel 2; independent sourcing/sinking enables dual-path signal processing |
| 7 | IN2− | Inverting input of Channel 2; matched DC specs enable precision differential amplification |
| 8 | IN2+ | Non-inverting input of Channel 2; identical AC/DC performance to Pin 3 for channel matching |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization from 2.5 V supply - critical for low-voltage battery monitoring |
| Ultra-low input bias current | 1 pA typ. - eliminates voltage error in photodiode or ion-selective electrode interfaces |
| AEC-Q100 Grade 1 qualification | Validated for −40 °C to +125 °C operation - meets automotive powertrain and body control requirements |
| Unity-gain stability | Eliminates need for external compensation in buffer or gain-of-one configurations |
| High output drive | ±35 mA - directly drives 2 kΩ loads or ADC reference buffers without external gain stages |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912IST | Same silicon, non-automotive grade; 1.5 mV max VOS only at 25 °C, not over full −40 to +125 °C range | Qualified for commercial/industrial use only; lacks AEC-Q100 stress testing and screening | Select when cost sensitivity outweighs automotive reliability requirements and ambient temperature stays <85 °C |
| TSV992IYDT | Higher 20 MHz GBP, 10 V/µs SR, but 3.5 mA supply current and no AEC-Q100 qualification | Targeted at high-speed data acquisition, not automotive or ultra-low-power systems | Choose only if bandwidth >10 MHz is mandatory and power budget allows 3× higher ICC |
Compared with TSV912IST, the TSV912IYST guarantees 1.5 mV max offset across automotive temperature range and includes enhanced ESD/latch-up hardening; versus TSV992IYDT, it trades speed for 65% lower quiescent current and certified automotive robustness.

FAQ
Is TSV912IYST pin-compatible with other MiniSO8 dual op amps?
No - TSV912IYST uses a non-standard MiniSO8 pinout: Pins 1–3 and 6–8 are signal terminals (OUT1, IN1−, IN1+, OUT2, IN2−, IN2+), while Pins 4 and 5 are VCC+ and VCC−. This differs from industry-standard dual op amp layouts like SO8 or TSSOP14, requiring PCB redesign for substitution.
What is the thermal resistance of the MiniSO8 package?
The MiniSO8 package has RthJA = 190 °C/W and RthJC = 39 °C/W, per DS4899 Rev 13 page 3. With 1.1 mA per channel (2.2 mA total) at 5 V, power dissipation is ~11 mW, resulting in <2.1 °C junction-to-ambient rise - well within safe limits even in sealed enclosures.
Can TSV912IYST drive capacitive loads above 100 pF?
Stable operation is guaranteed only up to 100 pF in unity-gain configuration. For larger loads (e.g., ADC input capacitance + PCB trace), ST recommends adding a 10–100 Ω series resistor between the op amp output and load, as shown in Figure 19 of DS4899, followed by bench validation.
Does the exposed pad on the MiniSO8 package require connection?
No - the exposed pad is not internally connected (per DS4899 Rev 13 page 17). It may be left floating or soldered to a ground plane for improved thermal conduction, but must never be tied to VCC+ or VCC− to avoid unintended current paths.
