Product details
Overview
TSV912AQPWRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 qualified rail-to-rail input/output operational amplifier designed for automotive signal conditioning. It delivers 8 MHz gain bandwidth, 4.5 V/µs slew rate, and 550 µA per channel quiescent current at 2.5–5.5 V supply, enabling precision low-side current sensing in HEV/EV motor control and ADAS sensor interfaces.
For engineers reviewing the TSV912AQPWRQ1 datasheet, TSV912AQPWRQ1 pinout, TSV912AQPWRQ1 application, or TSV912AQPWRQ1 equivalent, key selection criteria include its ±1.85 mV max input offset voltage over temperature, 1 pA typical input bias current, rail-to-rail operation down to 2.5 V, and integrated RFI-EMI rejection filter for robustness in noisy automotive environments.
Technical Context
The TSV912AQPWRQ1 employs a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail input operation across 2.5–5.5 V supply, with common-mode range extending 100 mV beyond both rails. Its unity-gain stable class AB output stage achieves ≤20 mV output swing from rails under 10 kΩ load.
It features an integrated RFI-EMI rejection filter, no phase reversal during overdrive, and ±4-kV HBM ESD protection. The device maintains ≥80 dB CMRR and ≥100 dB open-loop gain over –40°C to 125°C, supporting high-accuracy DC-coupled sensor amplification and active filtering in safety-critical systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz - supports stable closed-loop operation up to 100 kHz with G = 100, suitable for ADC driver and filter stages in infotainment audio paths. |
| Input Offset Voltage (max) | ±1.85 mV at TA = 25°C - enables accurate unidirectional current sensing with <0.5% error at 100 mV shunt drop. |
| Quiescent Current per Channel | 550 µA (typical) at VS = 5.5 V - allows dual-channel operation in always-on body electronics without excessive battery drain. |
| Input Bias Current (typ) | 1 pA - permits use with high-impedance sources (e.g., thermistors, piezoelectric sensors) without significant offset error. |
| Supply Voltage Range | 2.5 V to 5.5 V - compatible with 3.3 V microcontroller I/O domains and 5 V legacy automotive subsystems. |
| Operating Temperature | –40°C to +125°C - meets AEC-Q100 Grade 1 requirements for under-hood and powertrain applications. |
| Output Swing (from rail) | ≤20 mV at RL = 10 kΩ - preserves full dynamic range when driving SAR ADCs with 0–VDD input ranges. |
Pinout & Package
TSSOP-8 (PW) package: 3.00 mm × 6.40 mm, surface-mount, moisture-sensitive level 1, RoHS-compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or next-stage input; capable of sourcing/sinking ±50 mA short-circuit current. |
| 2 | IN1– | Inverting input, channel A - accepts feedback network or inverted signal path; rail-to-rail common-mode range includes V– and V+. |
| 3 | IN1+ | Noninverting input, channel A - connects to sensor, reference, or signal source; ultra-low 1 pA bias current minimizes loading error. |
| 4 | V– | Negative supply or ground - referenced for single-supply operation; must be stable and low-impedance to maintain PSRR >70 dB. |
| 5 | IN2+ | Noninverting input, channel B - independent input for second signal path; identical DC/AC specs to channel A. |
| 6 | IN2– | Inverting input, channel B - supports differential configuration or independent gain setting; shares same input stage architecture as IN1–. |
| 7 | OUT B | Amplifier B output - electrically isolated from OUT A; channel separation >100 dB at DC ensures minimal crosstalk in dual-sensor systems. |
| 8 | V+ | Positive supply - supplies both amplifiers; decoupling capacitor (≥100 nF) required within 5 mm for stable 8 MHz operation. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization in 3.3 V and 5 V single-supply systems, eliminating level-shifting components in ADC front-ends. |
| Integrated RFI-EMI rejection filter | Reduces susceptibility to GSM, Bluetooth, and switching regulator noise without external RC filters, critical for infotainment head unit audio amps. |
| No phase reversal on overdrive | Prevents latch-up or erroneous control signals during transient overload (e.g., motor startup surges), enhancing functional safety in ADAS actuators. |
| ±4-kV HBM ESD protection | Meets AEC-Q100 stress test requirements, allowing direct PCB mounting in exposed connectors (e.g., OBD-II, camera modules) without added TVS diodes. |
| Low 18 nV/√Hz input voltage noise | Supports high-resolution measurement of low-level sensor outputs (e.g., current shunts, thermopiles) without degrading SNR below 100 kHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV932QDRQ1 | Lower GBW (1.5 MHz), higher IQ (120 µA/channel), same RRIO and AEC-Q100 Grade 1 rating. | Better suited for ultra-low-power always-on body control modules where bandwidth <200 kHz suffices. | Select when system bandwidth demand is <200 kHz and quiescent current budget is tighter than 550 µA/channel. |
| TSZ122ILT | Higher precision (150 µV max VOS), lower noise (12 nV/√Hz), but not AEC-Q100 qualified and limited to 125°C max junction temp. | Applicable in industrial-grade ADAS subassemblies where automotive qualification is waived but DC accuracy is paramount. | Choose only for non-safety-critical industrial derivatives; not acceptable for production automotive ECUs requiring AEC-Q100 compliance. |
Compared with LMV932QDRQ1 and TSZ122ILT, the TSV912AQPWRQ1 uniquely balances 8 MHz bandwidth, AEC-Q100 Grade 1 qualification, and 550 µA/channel power-making it optimal for real-time motor control and high-fidelity sensor signal chains where speed, reliability, and efficiency are jointly constrained.

FAQ
What is the maximum input offset voltage specification for TSV912AQPWRQ1 over temperature?
The TSV912AQPWRQ1 has a maximum input offset voltage of ±3 mV across the full operating temperature range of –40°C to +125°C, with a typical value of ±0.3 mV at 25°C. This specification ensures reliable performance in under-hood applications where thermal drift must remain tightly bounded for accurate current or voltage sensing.
Does TSV912AQPWRQ1 support single-supply operation?
Yes, TSV912AQPWRQ1 supports true single-supply operation from 2.5 V to 5.5 V. Its rail-to-rail input extends 100 mV beyond both supply rails, and its rail-to-rail output swings to within 20 mV of V– and V+, enabling full dynamic range utilization in 3.3 V microcontroller-based automotive modules without dual supplies.
What package options are available for TSV912AQPWRQ1?
The TSV912AQPWRQ1 is offered in three automotive-qualified packages: SOIC-8 (D), TSSOP-8 (PW), and VSSOP-8 (DGK). The PW variant (TSSOP-8) used in this listing measures 3.00 mm × 6.40 mm and provides optimized thermal resistance (RθJA = 205.1°C/W) for compact PCB layouts in space-constrained ECUs.
How does the integrated RFI-EMI rejection filter benefit TSV912AQPWRQ1 in automotive designs?
The integrated RFI-EMI rejection filter in TSV912AQPWRQ1 attenuates high-frequency interference from sources like ignition systems, DC-DC converters, and wireless transceivers without requiring external RC networks. This reduces board area, BOM count, and layout sensitivity-particularly valuable in infotainment head units and ADAS domain controllers exposed to intense RF environments.
Is TSV912AQPWRQ1 pin-compatible with other devices in the TSV91x family?
No, TSV912AQPWRQ1 is not pin-compatible with TSV911A-Q1 (5-pin) or TSV914A-Q1 (14-pin); however, all TSV912A-Q1 variants (D, PW, DGK) share identical 8-pin pinouts and functions. Pin compatibility is maintained across SOIC, TSSOP, and VSSOP packages for the dual-channel version, simplifying footprint reuse in multi-package sourcing strategies.
