Product details
Overview
TSV912AIDT 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, 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 instrumentation.
For engineers reviewing the TSV912AIDT datasheet, TSV912AIDT pinout, TSV912AIDT application, or TSV912AIDT equivalent, key selection criteria include rail-to-rail output swing at 2.5 V supply, unity-gain stability with capacitive loads up to 100 pF, ultra-low input bias current for high-impedance source compatibility, and A-grade offset voltage specification for precision DC-coupled stages.
Technical Context
The TSV912AIDT implements a CMOS input stage with rail-to-rail differential pair and Class AB output stage, enabling full-swing operation at 2.5 V supply. Its 8 MHz GBP and 4.5 V/μs slew rate support stable unity-gain configurations while driving ≥2 kΩ resistive loads or ≤100 pF capacitive loads without external compensation.
It features internal ESD protection ≥5 kV HBM and latch-up immunity of 200 mA, with guaranteed operation across –40 °C to +125 °C. The A-grade variant specifies 1.5 mV max input offset voltage at 25 °C and 3 mV max over temperature, supporting precision applications where DC accuracy is critical.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable amplification up to ~1 MHz at gain = 8, suitable for anti-aliasing and active filter design. |
| Slew rate | 4.5 V/μs - supports 10 kHz full-scale sine output at 2.8 Vpp without distortion in 3.3 V systems. |
| Input offset voltage (A grade) | 1.5 mV max at 25 °C - limits DC error to <0.3% of 500 mV sensor output, critical for medical front-ends. |
| Supply current per channel | 0.78–1.1 mA - allows dual op-amp operation on coin-cell batteries for >1-year portable device lifetime. |
| Input bias current | 1 pA typ. - preserves signal integrity when interfacing with >1 GΩ pH electrodes or piezoelectric sensors. |
| Rail-to-rail I/O | Operates with inputs within 100 mV of rails and outputs within 40 mV of rails at 10 kΩ load - maximizes dynamic range in 2.5 V systems. |
| Common-mode rejection | 62–82 dB - rejects power-supply ripple and shared-noise coupling in single-supply sensor nodes. |
Pinout & Package
TSV912AIDT is supplied in SO8 (Small Outline Integrated Circuit, 150 mil width) package with standard dual-op-amp pinout. The exposed pad is not internally connected and may be left floating or tied to VCC− for thermal enhancement.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | Inverting input (Channel 1) | Accepts feedback network connection; high-impedance node requiring guard ring layout for pA-level bias current performance. |
| 2 | Non-inverting input (Channel 1) | Connects to high-impedance sensor sources; 1 pA bias current minimizes loading error on microamp-level transducer outputs. |
| 3 | Output (Channel 1) | Delivers rail-to-rail swing up to ±35 mA sink/source; stable with 100 pF capacitive load in unity-gain buffer configuration. |
| 4 | VCC− (Ground / Negative Supply) | Reference for both channels; decoupling capacitor (10 nF) must be placed <2 mm from this pin to suppress PSRR degradation. |
| 5 | Output (Channel 2) | Independent output stage; enables dual-path signal conditioning (e.g., differential input + reference buffer) without crosstalk. |
| 6 | Non-inverting input (Channel 2) | Electrically isolated from Channel 1 inputs; supports independent sensor channel routing on PCB. |
| 7 | Inverting input (Channel 2) | Accepts second feedback network; pin-compatible with industry-standard dual op-amp layouts. |
| 8 | VCC+ (Positive Supply) | Supports 2.5–5.5 V operation; internal regulation ensures consistent GBP and offset performance across voltage range. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full utilization of 2.5 V supply range - eliminates need for level-shifting in portable ECG front-ends. |
| Unity-gain stable | Permits direct use as voltage follower without external compensation, reducing BOM count in active filters. |
| 820 µA typical supply current per channel | Allows dual-channel operation at <1.7 mA total - extends battery life in wearable pulse oximeters beyond 24 months. |
| 1.5 mV max input offset (A grade) | Reduces calibration frequency in industrial 4–20 mA transmitter designs, lowering field maintenance cost. |
| ESD protection ≥5 kV HBM | Meets IEC 61000-4-2 Level 3 requirements for handheld medical devices without external TVS diodes. |
Applications
| Portable ECG Monitor | Battery-Powered Gas Sensor |

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 |
|---|---|---|---|
| TSV912IDT | Standard grade: 4.5 mV max offset vs. 1.5 mV max for A grade; otherwise identical specs and pinout. | Acceptable for AC-coupled or digitally calibrated systems where DC accuracy is relaxed. | Select TSV912IDT when offset drift tolerance exceeds ±3 mV and cost reduction is prioritized over factory calibration effort. |
| MCP6022-E/SN | Lower GBP (10 MHz) but higher supply current (1 mA/ch); 2.5 mV max offset; no A-grade option. | Requires larger decoupling due to poorer PSRR (70 dB vs. 86 dB); less suitable for noisy automotive 12 V-derived 3.3 V rails. | Choose only if legacy Microchip qualification is mandated; avoid where 1 pA bias current or 82 dB CMRR is required. |
Compared with TSV912IDT, the TSV912AIDT trades minor cost increase for guaranteed 1.5 mV offset - eliminating post-production trimming in medical devices. Against MCP6022-E/SN, it delivers superior DC precision and noise immunity at lower quiescent current, making it optimal for battery-constrained, high-accuracy analog front-ends.

FAQ
What is the maximum capacitive load the TSV912AIDT can drive without oscillation?
The TSV912AIDT is unity-gain stable and can drive up to 100 pF capacitive load directly in voltage-follower configuration without external compensation, as verified in Figure 10 of DS4899 Rev 13. For loads exceeding 100 pF, a series output resistor (e.g., 10–47 Ω) is recommended to maintain phase margin above 45°.
Does the TSV912AIDT support true split-supply operation?
Yes - the TSV912AIDT operates with VCC+ and VCC− pins, allowing symmetric supplies (e.g., ±2.5 V) or asymmetric configurations (e.g., +5 V / 0 V). Input common-mode range extends 100 mV beyond both rails, and output swings to within 40 mV of either rail under 10 kΩ load, enabling robust performance in bipolar signal chains.
How does the A-grade offset voltage specification differ from standard grade across temperature?
The TSV912AIDT guarantees ≤1.5 mV input offset at 25 °C and ≤3 mV over –40 °C to +125 °C, whereas the standard TSV912IDT specifies ≤4.5 mV at 25 °C and ≤7.5 mV over temperature. This 2× tighter DC accuracy reduces calibration burden in medical and industrial measurement systems.
Is the SO8 package of TSV912AIDT RoHS and REACH compliant?
Yes - the TSV912AIDT SO8 package carries ECOPACK2 certification per STMicroelectronics' environmental compliance program, meeting RoHS Directive 2011/65/EU and REACH Regulation (EC) No. 1907/2006, including SVHC screening.
