Product details
Overview
TSV912AIDSGR 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 ±1.5-mV maximum input offset voltage across –40°C to 125°C - enabling high-fidelity sensor interfacing in battery-powered HVAC controllers and motor control feedback loops.
For engineers reviewing the TSV912AIDSGR datasheet, TSV912AIDSGR pinout, TSV912AIDSGR application, or TSV912AIDSGR equivalent, key selection considerations include its WSON-8 (DSG) package with exposed thermal pad, unity-gain stability with capacitive load tolerance up to 300 pF, rail-to-rail operation from 2.5 V to 5.5 V, and ultra-low 1-pA typical input bias current for high-impedance source compatibility.
Technical Context
The TSV912AIDSGR 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 integrates an RFI-EMI rejection filter and avoids phase reversal during overdrive.
This dual op amp features independent channel operation with no crosstalk degradation below –100 dB at DC and >80 dB up to 1 MHz, supports low-voltage sampling of ADCs via rail-to-rail output swing (within 15 mV of rails at 5.5 V), and maintains ±0.5 µV/°C typical offset drift for stable performance in automotive infotainment and medical instrumentation environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz - enables stable unity-gain buffer and closed-loop amplification up to ~700 kHz with 10× gain while preserving phase margin. |
| Input Offset Voltage (max) | ±1.5 mV - ensures ≤0.03% error in 5-V full-scale sensor signal conditioning without trimming. |
| Quiescent Current (typ) | 550 µA per amplifier - allows dual-channel operation on coin-cell or energy-harvesting supplies for portable medical devices. |
| Input Bias Current (typ) | 1 pA - permits use with >100-MΩ source impedances (e.g., pH electrodes, piezoelectric sensors) without significant voltage error. |
| Supply Voltage Range | 2.5 V to 5.5 V - supports direct connection to Li-ion (3.0–4.2 V), USB (5 V), or regulated 3.3-V rails without level-shifting. |
| Output Swing (from rail) | 15 mV at 5.5 V / 10-kΩ load - delivers >99.7% dynamic range to 12-bit+ ADCs with minimal headroom loss. |
| CMRR (min) | 80 dB at –40°C to 125°C - rejects common-mode noise in noisy motor drive or industrial power module environments. |
Pinout & Package
TSV912AIDSGR is housed in an 8-pin WSON package (DSG) with 2.00 mm × 2.00 mm body size and an exposed thermal pad on the underside, which must be connected to V– for optimal thermal performance and EMI suppression.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives downstream circuitry; rail-to-rail swing supports direct ADC interface. |
| 2 | –IN A | Inverting input, channel A - used in standard inverting configurations or as summing node. |
| 3 | +IN A | Noninverting input, channel A - accepts high-impedance sensor signals with <1-pA bias current error. |
| 4 | V– | Negative supply or ground - reference for both amplifiers; connects to exposed thermal pad for thermal/EMI integrity. |
| 5 | V+ | Positive supply - powers both channels; operates down to 2.5 V for ultra-low-voltage applications. |
| 6 | –IN B | Inverting input, channel B - electrically isolated from channel A; supports dual-sensor or differential pair processing. |
| 7 | OUT B | Amplifier B output - independent output path; no crosstalk degradation below –100 dB at DC. |
| 8 | +IN B | Noninverting input, channel B - identical input characteristics to +IN A; enables matched dual-channel designs. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Common-mode range extends 100 mV beyond V– and V+, output swings within 15 mV of rails - maximizes signal fidelity in low-voltage systems. |
| Ultra-low input bias current (1 pA typ) | Enables accurate amplification of microcurrent sources (e.g., photodiodes, ion-selective electrodes) without loading error. |
| Integrated RFI-EMI rejection filter | Suppresses high-frequency interference from switching regulators or RF transceivers without external components. |
| No phase reversal in overdrive | Prevents latch-up or erroneous output behavior when inputs exceed supply rails - critical for robust motor control feedback. |
| ±4-kV HBM ESD protection | Meets IEC 61000-4-2 Level 2 requirements - reduces need for external protection in industrial and automotive PCB layouts. |

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 |
|---|---|---|---|
| TLV9002IDSGR | Lower 1.2-MHz GBW, higher 650-µA IQ, same DSG package and 1-pA IB. | Better suited for ultra-low-speed, ultra-low-power applications (e.g., static sensor monitoring) where bandwidth <2 MHz suffices. | Select TLV9002IDSGR only if system bandwidth requirement is ≤1.2 MHz and lower cost is prioritized over speed. |
| OPA2316IDSGR | Higher 10-MHz GBW, 1.2-mA IQ, 0.2-pA IB, same DSG footprint but requires different layout for thermal pad grounding. | Preferred for high-speed active filters or multi-pole compensation where phase margin above 60° at 10 MHz is required. | Choose OPA2316IDSGR when design demands >8-MHz bandwidth or sub-0.5-pA bias current - verify thermal pad connection per TI SLOA197. |

FAQ
What is the maximum capacitive load the TSV912AIDSGR can drive while maintaining stability?
The TSV912AIDSGR is unity-gain stable and supports capacitive loads up to 300 pF with controlled overshoot (<60%) and ≥55° phase margin, as verified in Figure C025 and C037 of the SBOS878D datasheet. For loads exceeding 300 pF, external isolation resistance (e.g., 10–50 Ω in series with output) is recommended to preserve stability in ADC driver or cable-driving applications.
Does the TSV912AIDSGR require external compensation for unity-gain operation?
No, the TSV912AIDSGR is internally compensated for unity-gain stability across its full operating range (2.5 V–5.5 V, –40°C to 125°C). No external compensation components are needed - confirmed by phase margin ≥55° at G = 1 in Figure C006 and Figure 31 of the SBOS878D datasheet.
How is the exposed thermal pad on the TSV912AIDSGR package intended to be connected?
The exposed thermal pad on the TSV912AIDSGR (DSG package) must be soldered to a PCB copper pour connected to the V– pin. This connection is mandatory for thermal dissipation, EMI suppression, and achieving specified RθJB = 61.3°C/W - as detailed in Section 6 ("Pin Configuration and Functions") and Table 7.5 of the SBOS878D datasheet.
Can the TSV912AIDSGR operate from a single 3.3-V supply?
Yes, the TSV912AIDSGR fully supports single-supply operation from 3.3 V, with rail-to-rail input (–0.1 V to 3.4 V) and output (within 15 mV of 0 V and 3.3 V) performance. Its 550-µA quiescent current and 18-nV/√Hz noise make it ideal for 3.3-V sensor interfaces in industrial and portable systems.
What is the guaranteed input offset voltage specification for TSV912AIDSGR over temperature?
The TSV912AIDSGR guarantees ±3 mV maximum input offset voltage across the full operating temperature range of –40°C to 125°C (per Section 7.7, "Electrical Characteristics"), with ±0.5 µV/°C typical drift - ensuring predictable error contribution in closed-loop systems without trimming.
