Product details
Overview
TSV912IST 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 battery-powered medical and automotive electronics.
For engineers reviewing the TSV912IST datasheet, TSV912IST pinout, TSV912IST application, or TSV912IST equivalent, key selection criteria include rail-to-rail I/O swing at 2.5 V supply, ultra-low input bias current for high-impedance source compatibility, unity-gain stability with capacitive loads up to 100 pF, and AEC-Q100–qualified variants for automotive use.
Technical Context
The TSV912IST implements 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). Its internal compensation ensures unity-gain stability without external components across its full operating temperature range (−40 °C to +125 °C).
It features a 75 dB minimum CMRR at 25 °C and 53 dB over temperature, 82 dB SVR at 5 V supply, and delivers ±35 mA output drive capability while maintaining 820 µA typical quiescent current per channel - balancing speed, precision, and power efficiency for portable instrumentation.
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, suitable for active filtering and sensor amplification. |
| Input offset voltage (max) | 1.5 mV (A grade) - enables ≤0.3% error in 0.5 V full-scale 12-bit ADC front-end without trimming. |
| Supply current (per channel) | 820 µA typ. - allows dual op-amp operation on coin-cell batteries for >1-year standby in portable diagnostics. |
| Slew rate | 4.5 V/μs - supports 1 kHz sine wave output up to 4.5 Vpp without distortion at 5 V supply. |
| Input bias current | 1 pA typ. - preserves signal integrity when amplifying outputs from pH electrodes or photodiode transimpedance stages. |
| Common-mode rejection | 53 dB min (−40 °C to +125 °C) - rejects power-supply ripple and EMI coupling in noisy automotive environments. |
| Output drive current | ±35 mA - directly drives 100 Ω loads or 10 kΩ DAC reference buffers without external boost. |
Pinout & Package
TSV912IST is housed in a 8-pin MiniSO8 package (3.0 mm × 3.0 mm, 0.65 mm pitch), thermally optimized with RthJA = 190 °C/W. The exposed pad is not internally connected and may be grounded or left floating per layout requirements.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT1 | Inverting amplifier output; capable of sourcing/sinking ±35 mA into resistive loads. |
| 2 | IN1− | Inverting input; accepts rail-to-rail common-mode signals from VCC− − 0.1 V to VCC+ + 0.1 V. |
| 3 | IN1+ | Non-inverting input; matched to IN1− for <1.5 mV offset in A-grade devices. |
| 4 | VCC− | Negative supply rail; referenced to system ground in single-supply configurations. |
| 5 | VCC+ | Positive supply rail; supports 2.5 V to 5.5 V operation with 70 dB SVR. |
| 6 | IN2+ | Non-inverting input of second op-amp; electrically isolated from Channel 1. |
| 7 | IN2− | Inverting input of second op-amp; independent bias and offset characteristics. |
| 8 | OUT2 | Second amplifier output; identical AC/DC specs to OUT1, fully decoupled. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 2.5 V single-supply systems, e.g., 0–2.5 V sensor output scaling. |
| Unity-gain stable | Operates reliably as buffer or gain=1 amplifier without external compensation, reducing BOM count. |
| Low input bias current (1 pA) | Minimizes voltage error across high-value feedback networks (>10 MΩ), critical for piezoelectric sensors. |
| 8 MHz bandwidth at 1.1 mA | Delivers 10× higher speed/power ratio than legacy low-power op-amps, enabling faster loop response. |
| ESD protection ≥5 kV HBM | Withstands handling and board-level ESD events without latch-up or parameter shift. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV912IDT | Same silicon, SO8 package (5.0 mm × 4.0 mm); RthJA = 125 °C/W vs. 190 °C/W for MiniSO8. | Better thermal performance in high-density PCBs; requires larger board area. | Select for designs needing lower junction temperature rise under sustained 35 mA output load. |
| TSV992IST | Higher 20 MHz GBP, 10 V/μs slew rate, but 1.4 mA supply current per channel and 3 mV offset (A grade). | Supports wider bandwidth signal chains (e.g., ultrasonic sensing), at cost of 71% higher quiescent power. | Choose when bandwidth >10 MHz is required and battery life is secondary to signal fidelity. |
Compared with TSV912IST, TSV912IDT offers superior thermal dissipation in space-tolerant layouts, while TSV992IST trades 71% higher supply current for double the bandwidth - making TSV912IST optimal for precision, low-power dual-op-amp roles where 8 MHz suffices.

FAQ
What is the maximum capacitive load the TSV912IST can drive without external compensation?
The TSV912IST is unity-gain stable and can drive up to 100 pF capacitive loads in voltage-follower configuration without oscillation, as verified in Figure 10 of DS4899 Rev 13. For loads exceeding 100 pF, a series resistor (typically 10–100 Ω) between output and load restores phase margin above 45°.
Does the TSV912IST support true single-supply operation down to 2.5 V?
Yes - the TSV912IST operates from 2.5 V to 5.5 V with rail-to-rail input common-mode range extending 0.1 V beyond both rails and output swing within 15 mV of each rail under 10 kΩ load, enabling direct interfacing with 2.5 V ADCs and logic without level-shifting.
How does the A grade (TSV912AIST) differ from standard TSV912IST in production testing?
The TSV912AIST undergoes enhanced screening to guarantee ≤1.5 mV input offset voltage at 25 °C and ≤3 mV over −40 °C to +125 °C, versus ≤4.5 mV (typ) and ≤7.5 mV (max) for standard grade - critical for untrimmed 12-bit measurement systems.
Can the exposed pad on the MiniSO8 package be connected to ground for improved thermal performance?
Yes - the exposed pad is not internally connected and may be soldered to a PCB thermal pad tied to VCC− (ground in single-supply) to reduce RthJA by ~20 °C/W, as confirmed in Section 6.3 of DS4899. Floating is also acceptable if thermal constraints permit.
