Product details
Overview
TSV914AQPWRQ1 from Texas Instruments is a quad-channel automotive-grade rail-to-rail input/output operational amplifier optimized for AEC-Q100 Grade 1 applications. It delivers 8 MHz gain-bandwidth, 4.5 V/µs slew rate, 550 µA per channel quiescent current, and ±1.85 mV maximum input offset voltage across –40°C to 125°C - enabling precision low-side current sensing in HEV/EV motor control and ADAS sensor interfaces.
For engineers reviewing the TSV914AQPWRQ1 datasheet, TSV914AQPWRQ1 pinout, TSV914AQPWRQ1 application, or TSV914AQPWRQ1 equivalent, key selection criteria include its unity-gain stability, 18 nV/√Hz input voltage noise at 1 kHz, rail-to-rail swing with ≤20 mV output saturation near rails (at 5.5 V, 10 kΩ), ultra-low 1 pA typical input bias current, and integrated RFI-EMI rejection filter for noisy automotive environments.
Technical Context
The TSV914AQPWRQ1 employs a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail input operation - with common-mode range extending 100 mV beyond both supply rails (V– – 0.1 V to V+ + 0.1 V) across 2.5 V–5.5 V supplies. Its class-AB output stage achieves full rail-to-rail output swing, delivering ≤20 mV headroom to either rail under 10 kΩ load at 5.5 V.
It is unity-gain stable and features no phase reversal during overdrive, 200 ns overload recovery time, and integrated EMI rejection filtering. The device supports single-supply operation down to 2.5 V and maintains 80 dB minimum CMRR over –40°C to 125°C, making it suitable for high-impedance sensor front-ends and ADC driver stages in safety-critical automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 8 MHz - enables stable closed-loop operation up to ~7.5 MHz at G = +1, supporting fast signal conditioning before ADC sampling. |
| Slew rate | 4.5 V/µs - ensures <1 µs settling to 0.01% for 2-V steps, critical for accurate current-sense pulse response in motor control. |
| Input offset voltage (max) | ±1.85 mV at 25°C - limits DC error in unidirectional low-side shunt sensing with 50 mΩ resistor at 10 A (500 mV full scale). |
| Quiescent current per channel | 550 µA (typical) at 5.5 V - allows four independent amplifiers in compact space without thermal derating in 125°C under-hood environments. |
| Input voltage noise density | 18 nV/√Hz at 1 kHz - preserves SNR in millivolt-level sensor signals (e.g., thermopiles, bridge sensors) without excessive filtering. |
| Common-mode rejection ratio | 80 dB min (–40°C to 125°C) - rejects battery rail fluctuations and ground bounce in body electronics and infotainment power domains. |
| ESD rating (HBM) | ±4 kV - meets AEC-Q100 stress requirements for assembly and field reliability in automotive production lines. |
Pinout & Package
TSSOP-14 (PW) package: 5.00 mm × 6.40 mm, 14-pin surface-mount, lead-free, RoHS-compliant, rated for –40°C to 125°C junction temperature.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - drives external load or ADC input; 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-sensing topologies. |
| 3 | IN+ A | Noninverting input, channel A - referenced to system ground or precision bias for differential measurement. |
| 4 | V+ | Positive supply rail - accepts 2.5 V–5.5 V; decoupling capacitor required within 1 cm for EMI immunity. |
| 5 | IN+ B | Noninverting input, channel B - enables dual-sensor monitoring (e.g., redundant wheel speed or torque sensing). |
| 6 | IN– B | Inverting input, channel B - paired with IN+ B for second independent differential gain stage. |
| 7 | OUT B | Amplifier B output - isolated signal path prevents crosstalk between safety-critical subsystems. |
| 8 | OUT C | Amplifier C output - supports third analog channel without external op-amp, reducing BOM count in cluster displays. |
| 9 | IN– C | Inverting input, channel C - used for feedback in active filters or transimpedance configurations for photodiode inputs. |
| 10 | IN+ C | Noninverting input, channel C - configurable as reference or sensor input in multi-zone HVAC control circuits. |
| 11 | V– | Negative supply or ground - must be low-impedance; shared return path impacts PSRR and noise coupling. |
| 12 | IN+ D | Noninverting input, channel D - enables fourth independent analog acquisition channel for OBC voltage monitoring. |
| 13 | IN– D | Inverting input, channel D - supports differential bus voltage sensing in 48 V mild-hybrid architectures. |
| 14 | OUT D | Amplifier D output - provides dedicated signal path for diagnostics or redundancy verification in ASIL-B systems. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV914IQPWRQ1 | Same quad-channel RRIO architecture but with ±0.3 mV typical offset (vs ±1.85 mV max for TSV914AQPWRQ1); identical pinout and specs otherwise. | Better suited for high-precision DC-coupled sensor interfaces where offset drift dominates error budget. | Select TSV914IQPWRQ1 when <0.5 mV total offset error is required across temperature; TSV914AQPWRQ1 remains optimal for cost-sensitive, wide-temp AC-coupled applications. |
| LMV984QDGKRQ1 | Quad RRIO op-amp with 1.8 MHz GBW, 1.5 V/µs slew rate, and 125 µA/channel IQ - lower speed and power than TSV914AQPWRQ1. | Targeted at low-bandwidth body electronics (e.g., window lift, seat position) where 8 MHz is unnecessary. | Choose LMV984QDGKRQ1 only for non-safety-critical, low-speed functions to reduce system power; avoid for ADAS or powertrain where bandwidth and settling matter. |
Compared with TSV914IQPWRQ1 and LMV984QDGKRQ1, the TSV914AQPWRQ1 uniquely balances 8 MHz bandwidth, 4.5 V/µs slew rate, and 550 µA/channel IQ - making it the only quad AEC-Q100 Grade 1 op-amp capable of simultaneously serving high-fidelity audio, radar IF, and motor current sensing in a single footprint.

FAQ
What is the maximum operating temperature range for the TSV914AQPWRQ1?
The TSV914AQPWRQ1 is qualified for continuous operation from –40°C to +125°C ambient temperature, meeting AEC-Q100 Grade 1 requirements. Its thermal metrics - including 111.1°C/W RθJA for SOIC-14 and 133.8°C/W for TSSOP-14 - ensure reliable junction temperatures below 150°C under typical automotive PCB layouts with 2 oz copper and two internal planes.
Does the TSV914AQPWRQ1 support single-supply operation?
Yes, the TSV914AQPWRQ1 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 (V– – 0.1 V to V+ + 0.1 V), and its rail-to-rail output swings to within 20 mV of either rail under 10 kΩ load - enabling direct interfacing with 3.3 V or 5 V microcontrollers and ADCs without level-shifting circuitry.
Is the TSV914AQPWRQ1 pin-compatible with other devices in the TSV91x-Q1 family?
No - the TSV914AQPWRQ1 (quad, 14-pin TSSOP/SOIC) is not pin-compatible with TSV911A-Q1 (single, 5-pin) or TSV912A-Q1 (dual, 8-pin). However, its TSSOP-14 pinout matches the TSV914IQPWRQ1 exactly, allowing drop-in replacement where tighter offset specifications are needed without layout changes.
What is the overload recovery time specification for the TSV914AQPWRQ1?
The TSV914AQPWRQ1 has a specified overload recovery time of 200 ns - defined as the time required for the output to transition from saturation back to linear operation after an overdrive event. This fast recovery supports accurate pulse-width measurement in motor phase current sensing and prevents distortion in high-frequency PWM-driven systems.
How does the TSV914AQPWRQ1 handle electromagnetic interference in automotive environments?
The TSV914AQPWRQ1 integrates an on-die RFI-EMI rejection filter that attenuates high-frequency noise above 100 MHz by >40 dB - validated per ISO 11452-2/4 standards. This eliminates the need for external LC filters in ADAS camera modules and infotainment systems exposed to cellular, Bluetooth, and switching power supply emissions.
