Product details
Overview
TSV912ID from STMicroelectronics is a dual rail-to-rail input/output operational amplifier in SO8 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. It is used in battery-powered medical instrumentation and automotive sensor interfaces.
For engineers reviewing the TSV912ID datasheet, TSV912ID pinout, TSV912ID application, or TSV912ID equivalent, key selection criteria include rail-to-rail I/O swing at low supply, ultra-low input bias current for high-impedance sources, unity-gain stability with capacitive load drive up to 100 pF, and AEC-Q100-compliant variants for automotive use.
Technical Context
The TSV912ID 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 2.5–5.5 V operating range.
It features 820 µA typical quiescent current per channel, 35 mA output drive capability (sourcing/sinking), and maintains ≥58 dB CMRR and ≥70 dB SVR over temperature. The device supports stable operation into 100 pF capacitive loads in follower configuration, with optional series output resistor for larger loads.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable closed-loop operation up to ~1 MHz at gain = 8, suitable for active filters and sensor amplification. |
| Input offset voltage (max) | 1.5 mV (A grade) - ensures ≤1.5 mV DC error at room temperature, critical for precision DC-coupled front-ends. |
| Input bias current (typ) | 1 pA - minimizes voltage error across high-impedance sensors (e.g., pH electrodes, photodiodes). |
| Slew rate | 4.5 V/μs - supports 1 kHz full-scale sine output up to ~7 Vpp at 5 V supply without distortion. |
| Supply current per channel | 820 µA typ. - enables dual op-amp operation under 1.7 mA total, ideal for multi-channel portable instrumentation. |
| Common-mode input range | VCC− − 0.1 V to VCC+ + 0.1 V - allows direct sensing of signals near ground or rail, e.g., single-supply bridge amplifiers. |
| Output drive (sourcing) | 35 mA - drives 100 Ω loads to within 150 mV of rails, supporting direct interface to ADC references or LED biasing. |
Pinout & Package
TSV912ID is housed in an 8-pin SO8 (Small Outline Integrated Circuit) package with standard dual op-amp pinout and exposed pad not internally connected. Pin 1 is Out1, Pin 2 is In1−, Pin 3 is In1+, Pin 4 is VCC−, Pin 5 is VCC+, Pin 6 is In2+, Pin 7 is In2−, Pin 8 is Out2.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Out1 | Inverting amplifier output channel 1; rail-to-rail swing supports full dynamic range utilization. |
| 2 | In1− | Inverting input for channel 1; matched to In1+ for <1.5 mV offset in A-grade devices. |
| 3 | In1+ | Non-inverting input for channel 1; accepts signals down to VCC− − 0.1 V for true single-supply operation. |
| 4 | VCC− | Negative supply rail (typically GND); decoupling capacitor required within 10 mm for stability. |
| 5 | VCC+ | Positive supply rail (2.5–5.5 V); powers both channels and sets common-mode and output swing limits. |
| 6 | In2+ | Non-inverting input for channel 2; electrically isolated from channel 1, enabling independent signal paths. |
| 7 | In2− | Inverting input for channel 2; supports differential configurations with matched input impedance. |
| 8 | Out2 | Inverting amplifier output channel 2; identical AC/DC specs to Out1 for synchronized dual-channel designs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full 0–VCC signal swing on both inputs and outputs, eliminating level-shifting in 3.3 V or lower systems. |
| Unity-gain stable | Operates stably at gain = 1 without external compensation, simplifying active filter and buffer designs. |
| Ultra-low input bias current | 1 pA typical allows use with >1 GΩ source impedances without significant DC error or drift. |
| 8 MHz bandwidth at low power | Delivers 8 MHz GBP while consuming only 820 µA per channel-optimal speed/power trade-off for portable apps. |
| ESD protection ≥5 kV HBM | Withstands human-body-model ESD events up to 5 kV, reducing need for external protection in board-level design. |
Applications
| Battery-Powered Medical Sensors | Automotive Cabin Pressure Monitoring |

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 |
|---|---|---|---|
| TSV912AIDT | Same SO8 package and pinout; tighter 1.5 mV max Vos (guaranteed A grade vs. standard TSV912ID's 4.5 mV max). | Required where DC accuracy dominates over cost; e.g., calibrated medical diagnostics. | Select when offset voltage spec must be guaranteed ≤1.5 mV across full temperature range. |
| TSV992IDT | Higher 20 MHz GBP and 10 V/μs slew rate; same 1 pA Ibias but higher 1.3 mA ICC per channel. | Suitable for wider-bandwidth active filters or faster sensor sampling, but increases power budget. | Choose when system requires >10× higher small-signal bandwidth and can accommodate +50% supply current. |
Compared with TSV912ID, TSV912AIDT improves DC precision without changing layout or supply, while TSV992IDT trades higher speed and current for greater signal fidelity in dynamic applications.

FAQ
Is TSV912ID unity-gain stable with capacitive loads?
Yes, TSV912ID is unity-gain stable and can drive up to 100 pF capacitive loads directly in voltage-follower configuration without oscillation. For loads exceeding 100 pF, ST recommends adding a small series resistor (e.g., 10–100 Ω) between the output and load to maintain phase margin above 45°, as verified in Figure 10 of DS4899.
What is the maximum operating junction temperature for TSV912ID?
The absolute maximum junction temperature for TSV912ID is 150 °C. With SO8 package thermal resistance RthJA = 125 °C/W, continuous operation at full 5.5 V supply and 35 mA output requires ambient temperature ≤85 °C when dissipating 110 mW (2 × 820 µA × 5.5 V + IOUT × VOL), assuming 10 nF local decoupling.
Does TSV912ID support single-supply operation below 3 V?
Yes, TSV912ID is fully specified from 2.5 V to 5.5 V. At 2.5 V, it maintains rail-to-rail input (down to −0.1 V relative to VCC−) and output swing within 40 mV of rails (at 10 kΩ load), enabling direct interfacing with 2.5 V ADCs and low-power microcontrollers without level-shifting circuitry.
How does the input offset voltage drift affect long-term accuracy?
TSV912ID exhibits ∆Vio/∆T = 5 µV/°C maximum. Over a −40 °C to 125 °C range (165 °C span), worst-case drift adds ≤825 µV to initial offset. Combined with 1.5 mV max initial Vos (A grade), total error remains ≤2.325 mV - sufficient for 12-bit systems with 1.2 V full-scale range (LSB = 293 µV).
