Product details
Overview
TSV912AIDSGT from Texas Instruments is a dual-channel rail-to-rail input/output operational amplifier optimized for low-power, precision signal conditioning in single-supply systems. It delivers 8 MHz gain bandwidth, 18 nV/√Hz input voltage noise at 1 kHz, 550 µA typical quiescent current per amplifier, and ±1 pA typical input bias current - enabling high-accuracy sensor interfacing and battery-powered motor control.
For engineers reviewing the TSV912AIDSGT datasheet, TSV912AIDSGT pinout, TSV912AIDSGT application, or TSV912AIDSGT equivalent, key selection criteria include its rail-to-rail operation down to 2.5 V supply, 1.5 mV maximum input offset voltage over temperature, unity-gain stability with capacitive loads up to 300 pF, and WSON-8 package with exposed thermal pad for thermal performance in compact industrial modules.
Technical Context
The TSV912AIDSGT employs a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail common-mode input range - extending 100 mV beyond both supply rails across 2.5 V–5.5 V operation. Its unity-gain stable architecture supports direct driving of SAR ADC inputs without external compensation.
It features integrated RFI-EMI rejection filtering, no phase reversal under overdrive, and robust ±4-kV HBM ESD protection. The dual-channel layout allows independent signal paths with >100 dB DC channel separation, supporting differential sensing and active filter topologies in space-constrained designs.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz - enables stable closed-loop operation up to ~700 kHz at G = +10 for anti-aliasing filters. |
| Input Offset Voltage (max) | ±1.5 mV - ensures ≤0.03% error in 5-V full-scale sensor output amplification. |
| Quiescent Current (per amp) | 550 µA (typ) - supports <1.1 mA total supply current for dual-channel operation in battery-critical systems. |
| Input Bias Current (typ) | ±1 pA - permits use with >10 MΩ source impedances (e.g., pH electrodes, piezoresistive sensors) without significant offset drift. |
| Supply Voltage Range | 2.5 V to 5.5 V - compatible with Li-ion (3.0–4.2 V), USB (5 V), and regulated 3.3 V rails without level-shifting. |
| Output Swing (RL = 2 kΩ) | Within 50 mV of rails at 5.5 V - maximizes dynamic range for 12-bit+ ADCs with single-supply front ends. |
| Phase Margin | 55° (G = 1) - guarantees stability with ≥100 pF load capacitance, critical for driving long PCB traces or capacitive sensors. |
Pinout & Package
TSV912AIDSGT is housed in an 8-pin WSON package (2.0 mm × 2.0 mm) with exposed thermal pad on underside, requiring connection to V– for optimal thermal performance (RθJA = 94.4°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry; rail-to-rail swing supports full-supply utilization. |
| 2 | –IN A | Inverting input, channel A - accepts feedback network for precise gain configuration. |
| 3 | +IN A | Noninverting input, channel A - high-impedance node for sensor or reference signal routing. |
| 4 | V– | Negative supply / ground - also connects to exposed thermal pad; mandatory for thermal reliability. |
| 5 | V+ | Positive supply - accepts 2.5–5.5 V; decoupling capacitor required within 1 cm for stability. |
| 6 | –IN B | Inverting input, channel B - electrically isolated from channel A; enables dual-path signal processing. |
| 7 | OUT B | Amplifier B output - independent output stage; supports simultaneous dual-sensor conditioning. |
| 8 | +IN B | Noninverting input, channel B - identical input characteristics to +IN A; maintains channel matching. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Common-mode range extends 100 mV beyond V– and V+, enabling direct interface with 0–5 V ADC references and low-voltage sensors. |
| Low input bias current (1 pA typ) | Minimizes voltage error across high-impedance sources (e.g., thermistors, photodiodes), preserving signal integrity without guard traces. |
| Integrated RFI-EMI rejection filter | Suppresses >40 dB of RF interference at 900 MHz, reducing need for external ferrite beads in automotive infotainment and industrial I/O modules. |
| No phase reversal in overdrive | Prevents latch-up or erroneous output transitions during input transients - critical for motor current sense amplifiers during fault conditions. |
| ±4-kV HBM ESD protection | Eliminates need for external TVS diodes in board-level ESD testing (IEC 61000-4-2 Level 2), lowering BOM count in consumer and medical devices. |
Applications
| Motor Current Sensing | Sensor Signal Conditioning |
|---|---|
|
Use Scenario: Real-time monitoring of phase currents in BLDC motor drivers using shunt resistors. IC Role / Device Role / Timing Role: Dual-channel TSV912AIDSGT configures one amp as a noninverting current sense amplifier (G = 20) and the other as a second-stage filter/level shifter.

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV932IDGKR | Lower GBW (1.5 MHz), higher IQ (120 µA per amp), no integrated EMI filter. | Limited to lower-frequency sensor buffering; lacks RFI immunity for noisy automotive environments. | Preferred only when cost sensitivity outweighs speed, noise, and EMI robustness requirements. |
| MCP6022-E/SN | Higher VOS (2.5 mV max), wider supply range (2.7–6.0 V), no ESD rating specified beyond JEDEC standard. | Acceptable for non-safety-critical industrial controls but not recommended for medical or automotive where guaranteed VOS and ESD margin matter. | Consider only if legacy design reuse or specific Microchip ecosystem integration is required. |
Compared with LMV932IDGKR and MCP6022-E/SN, the TSV912AIDSGT provides superior small-signal fidelity (8 MHz vs ≤1.5 MHz), lower system-level noise floor (18 nV/√Hz), and built-in EMI resilience - making it the preferred choice for next-generation battery-powered and automotive-qualified signal chains where accuracy and reliability are co-prioritized.

FAQ
What is the maximum capacitive load the TSV912AIDSGT can drive while maintaining stability?
The TSV912AIDSGT remains unity-gain stable with capacitive loads up to 300 pF, as verified by overshoot and phase margin measurements in the official datasheet (Figure C025/C026). This capability eliminates the need for isolation resistors when driving ADC input capacitors or long PCB traces, simplifying layout in compact designs.
Does the TSV912AIDSGT require external ESD protection in typical industrial applications?
No - the TSV912AIDSGT integrates ±4-kV human-body model (HBM) ESD protection on all pins, meeting IEC 61000-4-2 Level 2 requirements. External TVS diodes are unnecessary unless system-level surge events exceed this rating, such as in unshielded outdoor industrial I/O.
Can the TSV912AIDSGT operate from a single 3.3-V supply while achieving rail-to-rail output swing?
Yes - the TSV912AIDSGT operates from 2.5 V to 5.5 V and delivers rail-to-rail output swing. At 3.3 V supply with 2-kΩ load, output swings within 50 mV of both rails, preserving >97% of full-scale dynamic range for 12-bit ADC interfacing without level-shifting circuitry.
How does the input bias current of the TSV912AIDSGT affect high-impedance sensor interfaces?
With ±1 pA typical input bias current, the TSV912AIDSGT introduces negligible voltage error across sensor impedances up to 100 MΩ. For example, a 10-MΩ thermistor source adds only 10 µV offset - well below its 1.5 mV max VOS, ensuring measurement integrity without guard-ring PCB layouts.
Is the exposed thermal pad on the TSV912AIDSGT WSON package required to be connected to a PCB copper plane?
Yes - the exposed thermal pad on the TSV912AIDSGT must be soldered to a V–-connected PCB copper pour to achieve the specified RθJA of 94.4°C/W. Leaving it floating degrades thermal performance by >40°C/W and risks exceeding junction temperature limits under continuous 1-mA output loading.
