Product details
Overview
TSV912AIYST from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in MiniSO8 package, designed for precision signal conditioning in low-voltage systems. It delivers 8 MHz gain-bandwidth product, 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 - enabling high-accuracy sensor interfacing in automotive and portable medical devices.
For engineers reviewing the TSV912AIYST datasheet, TSV912AIYST pinout, TSV912AIYST application, or TSV912AIYST equivalent, key selection criteria include its A-grade offset voltage specification, rail-to-rail output swing into 600 Ω loads, unity-gain stability with 100 pF capacitive load capability, and AEC-Q100 qualified automotive temperature range (−40 °C to +125 °C).
Technical Context
The TSV912AIYST implements a CMOS input stage enabling ultra-low 1 pA input bias current and 1.5 mV max input offset voltage at 25 °C, with only 5 µV/°C drift over temperature. Its internal compensation ensures unity-gain stability without external components while supporting full rail-to-rail output swing across 2.5–5.5 V supply.
It features 820 µA typical quiescent current per channel, 35 mA output drive capability (sourcing/sinking), and 75 dB minimum CMRR at 25 °C - making it suitable for high-impedance sensor front-ends and battery-powered active filters where DC accuracy and low power coexist.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - supports stable closed-loop operation up to ~1 MHz with gain ≥ 8, critical for anti-aliasing and reconstruction filters. |
| Input offset voltage (max) | 1.5 mV - enables <0.03% error in 50 mV full-scale sensor outputs without trimming. |
| Supply current per channel | 820 µA typ. - allows dual op-amp operation on coin-cell batteries for >1 year in always-on monitoring nodes. |
| Slew rate | 4.5 V/µs - supports 1 kHz sine wave output at 10 Vpp without distortion in unity-gain buffer configurations. |
| Common-mode rejection ratio | 75 dB min - rejects >5,600× common-mode noise in differential sensor interfaces with mismatched PCB traces. |
| Output drive (sourcing) | 35 mA - drives 100 Ω loads directly, eliminating need for external buffers in analog output stages. |
| ESD protection | ≥5 kV HBM - withstands handling and board-level ESD events without latch-up or parameter shift. |
Pinout & Package
TSV912AIYST uses the MiniSO8 package (3.0 mm × 3.0 mm, 0.65 mm pitch), optimized for space-constrained automotive modules. The exposed pad is not internally connected and may be grounded or left floating per layout requirements.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Amplified output of Channel 1; rail-to-rail swing supports full dynamic range utilization. |
| 2 | IN1− | Inverting input of Channel 1; high-impedance CMOS node sensitive to leakage paths. |
| 3 | IN1+ | Non-inverting input of Channel 1; matched to IN1− for optimal CMRR performance. |
| 4 | VCC+ | Positive supply rail; decoupling capacitor must be placed ≤2 mm away to maintain stability. |
| 5 | VCC− | Negative supply rail (typically GND); shared return path for both channels' quiescent current. |
| 6 | OUT2 | Amplified output of Channel 2; independent of OUT1, enabling dual-path signal processing. |
| 7 | IN2− | Inverting input of Channel 2; electrically isolated from Channel 1 inputs to prevent crosstalk. |
| 8 | IN2+ | Non-inverting input of Channel 2; identical electrical characteristics to IN1+ for matched gain staging. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.5–5.5 V supply range - no headroom loss when interfacing with 3.3 V ADCs or microcontroller I/O. |
| A-grade input offset voltage | 1.5 mV max at 25 °C - reduces calibration overhead in factory-trimmed medical sensor modules. |
| Unity-gain stable | Operates without external compensation in follower, integrator, or transimpedance configurations - simplifies layout and BOM. |
| Automotive qualification | AEC-Q100 Grade 1 (−40 °C to +125 °C) - certified for engine control, body electronics, and ADAS subsystems. |
| Low input bias current | 1 pA typ. - prevents signal degradation in high-Z pH electrodes, piezoelectric sensors, and photodiode transimpedance amps. |
Applications
| Automotive Cabin Sensors | Portable ECG Front-End |

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 | Standard grade (7.5 mV max Vio vs. 1.5 mV), same package and pinout. | Acceptable for non-critical industrial sensing where calibration is performed. | Select when cost sensitivity outweighs need for factory-trimmed offset performance. |
| TSV992IDT | Higher 20 MHz GBP, 10 V/µs SR, but 3.5 mV max Vio and 1.2 mA ICC per channel. | Better for wideband active filters; less suitable for ultra-low-power battery operation. | Choose when bandwidth and slew rate dominate over quiescent current and DC precision. |
Compared with TSV912IST, the TSV912AIYST trades higher unit cost for guaranteed 1.5 mV offset and automotive qualification; versus TSV992IDT, it prioritizes sub-1 mA power and DC accuracy over speed - making it optimal for precision, low-power, AEC-Q100-compliant designs.

FAQ
Is TSV912AIYST pin-compatible with other MiniSO8 dual op-amps?
Yes - TSV912AIYST follows the industry-standard MiniSO8 pinout for dual op-amps (OUT1, IN1−, IN1+, VCC+, VCC−, OUT2, IN2−, IN2+), matching pin-for-pin layouts of TSV912IST, LMV358, and MCP6022. No PCB redesign is needed when upgrading from standard-grade to A-grade variants.
What is the maximum capacitive load the TSV912AIYST can drive without oscillation?
The TSV912AIYST remains unity-gain stable with up to 100 pF capacitive load in voltage-follower configuration. For loads exceeding 100 pF, ST recommends adding a 10–100 Ω series resistor between the output pin and the load capacitance to restore phase margin above 45°.
Does the exposed pad on the MiniSO8 package require connection?
No - the exposed pad of the TSV912AIYST MiniSO8 package is not internally connected. It may be soldered to a ground plane for thermal improvement or left floating; neither choice affects electrical performance or reliability under AEC-Q100 conditions.
How does the 1 pA input bias current impact high-impedance sensor interfaces?
At 1 pA typical, the TSV912AIYST introduces <1 mV error across a 1 MΩ source impedance - enabling direct connection to pH electrodes, photodiodes, and piezoresistive sensors without guard rings or bias-current cancellation networks, preserving signal integrity in ultra-high-Z applications.
