Product details
Overview
TSV914AQDRQ1 from Texas Instruments is a quad-channel automotive-grade rail-to-rail input/output operational amplifier designed for precision signal conditioning in AEC-Q100 Grade 1 systems. It delivers 8 MHz gain bandwidth, 4.5 V/µs slew rate, 18 nV/√Hz input voltage noise at 1 kHz, 550 µA quiescent current per channel, and operates from 2.5 V to 5.5 V supply. It is used in HEV/EV motor control current sensing and ADAS sensor front-ends.
For engineers reviewing the TSV914AQDRQ1 datasheet, TSV914AQDRQ1 pinout, TSV914AQDRQ1 application, or TSV914AQDRQ1 equivalent, this page provides verified technical context, package-specific pin functions, real-world automotive use cases, and validated alternative options - all aligned with TI's SBOSA18C (June 2023) production data sheet.
Technical Context
The TSV914AQDRQ1 implements a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail input operation across its full 2.5 V–5.5 V supply range, with common-mode voltage 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 integrates RFI-EMI rejection filtering, exhibits no phase reversal during overdrive, and supports stable operation into capacitive loads up to 300 pF with ≥55° phase margin. The device maintains ±0.5 µV/°C typical offset drift and 80–103 dB CMRR over –40°C to 125°C.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth Product | 8 MHz - enables stable closed-loop operation up to 100 kHz with G = 100, suitable for ADC driver and active filter stages. |
| Slew Rate | 4.5 V/µs - supports fast transient response in motor current sensing and safety-critical feedback loops. |
| Input Voltage Noise | 18 nV/√Hz at 1 kHz - low enough for high-resolution current shunt amplification without degrading SNR. |
| Quiescent Current | 550 µA per channel - allows four independent amplifiers in space-constrained body electronics with minimal thermal impact. |
| Input Offset Voltage | ±1.85 mV max (25°C), ±3 mV max (–40°C to 125°C) - ensures <0.5% error in 500-mV full-scale current-sense applications. |
| Common-Mode Rejection | 80–103 dB - suppresses battery rail fluctuations in single-supply low-side sensing configurations. |
| Supply Voltage Range | 2.5 V to 5.5 V - compatible with 3.3 V microcontroller I/O domains and 5 V analog subsystems in modern automotive ECUs. |
Pinout & Package
TSV914AQDRQ1 is packaged in a 14-pin SOIC (D package), 8.65 mm × 6.00 mm body size, with exposed pad not present. Thermal resistance RθJA = 111.1°C/W enables operation at full rated junction temperature (150°C) with standard PCB copper area.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives ADC input or next-stage filter; rail-to-rail swing supports full dynamic range utilization. |
| 2 | IN– A | Inverting input, channel A - connects to shunt resistor low-side node in current-sense circuits. |
| 3 | IN+ A | Noninverting input, channel A - referenced to system ground or bias network for differential measurement. |
| 4 | V+ | Positive supply - accepts 2.5–5.5 V; decoupling capacitor required within 5 mm for EMI immunity. |
| 5 | IN+ B | Noninverting input, channel B - isolated input path for redundant sensor channels in ASIL-B designs. |
| 6 | IN– B | Inverting input, channel B - paired with IN+ B for second independent current or voltage monitoring path. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV984QDRQ1 | Lower GBW (1.8 MHz), higher quiescent current (1.2 mA/ch), same AEC-Q100 Grade 1 rating and SOIC-14 package. | Better DC precision (0.5 mV VOS max) but insufficient bandwidth for >50 kHz PWM current reconstruction. | Select when ultra-low offset dominates over speed; avoid for motor control loop closure above 10 kHz. |
| TLV9064QDRQ1 | Higher GBW (10 MHz), faster slew rate (6.5 V/µs), same 550 µA/ch IQ and rail-to-rail I/O, but only qualified to AEC-Q100 Grade 2 (–40°C to 105°C). | Superior AC performance enables higher-resolution encoder interpolation and faster fault detection. | Select for cabin or chassis ECUs operating below 105°C ambient; not approved for engine bay or powertrain locations. |
Compared with LMV984QDRQ1, TSV914AQDRQ1 trades DC precision for 4.4× higher bandwidth and 2.2× lower power-critical for real-time motor control. Against TLV9064QDRQ1, it sacrifices 2 MHz bandwidth and 2 V/µs slew rate to meet Grade 1 temperature requirements essential for powertrain integration.

FAQ
What is the maximum operating temperature for TSV914AQDRQ1?
The TSV914AQDRQ1 is qualified to AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. Its junction temperature limit is 150°C, and thermal data confirms RθJA = 111.1°C/W for the SOIC-14 package-enabling reliable function in engine control units and powertrain modules without forced cooling.
Does TSV914AQDRQ1 support single-supply operation?
Yes, TSV914AQDRQ1 fully supports single-supply operation from 2.5 V to 5.5 V. Its rail-to-rail input extends 100 mV beyond both supply rails, and rail-to-rail output swings to within 20 mV of V+ and V– under 10 kΩ load-making it ideal for 3.3 V or 5 V automotive subsystems without dual supplies.
What is the input offset voltage specification for TSV914AQDRQ1?
TSV914AQDRQ1 has a maximum input offset voltage of ±1.85 mV at 25°C and ±3 mV across the full –40°C to +125°C temperature range. This is measured per channel under standard test conditions (VS = 5 V, RL = 10 kΩ), ensuring predictable error bounds in precision current-sense and sensor interface applications.
Is TSV914AQDRQ1 pin-compatible with other devices in the TSV91x-Q1 family?
No-TSV914AQDRQ1 (quad, SOIC-14) is not pin-compatible with TSV911A-Q1 (single, SOT-23-5/SC70-5) or TSV912A-Q1 (dual, SOIC-8/VSSOP-8/TSSOP-8). Pin count, layout, and channel mapping differ fundamentally; PCB redesign is required when substituting between channel counts.
What packaging options are available for TSV914AQDRQ1?
TSV914AQDRQ1 is offered exclusively in the 14-pin SOIC (D) package (8.65 mm × 6.00 mm) and 14-pin TSSOP (PW) package (5.00 mm × 6.40 mm). The "QDRQ1" suffix in the part number explicitly denotes the SOIC-14 variant with automotive qualification and green (RoHS-compliant) finish.
