Product details
Overview
TLV9064QPWRQ1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, 10 MHz unity-gain bandwidth, ±0.3 mV input offset voltage, and 538 µA quiescent current per amplifier-designed for precision signal conditioning in HEV/EV motor control and ADAS current-sensing circuits.
For engineers reviewing the TLV9064QPWRQ1 datasheet, TLV9064QPWRQ1 pinout, TLV9064QPWRQ1 application, or TLV9064QPWRQ1 equivalent, this page delivers verified electrical specs, SOIC-14 and TSSOP-14 package details, functional safety documentation support, and validated alternatives for automotive-grade op amp selection.
Technical Context
The TLV9064QPWRQ1 implements a CMOS input stage with resistive open-loop output impedance (100 Ω at 10 MHz), enabling stable operation with >100 pF capacitive loads without external compensation. Its internal RFI/EMI filter and no-phase-reversal overdrive behavior support robust analog front-end design in noisy automotive environments.
It operates across 1.8 V to 5.5 V supply rails, supports single- or dual-supply configurations, and maintains ≥80 dB CMRR and ≥100 dB open-loop gain over –40°C to +125°C ambient temperature-meeting AEC-Q100 Grade 1 thermal requirements for powertrain and body electronics.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 10 MHz - enables high-speed closed-loop designs up to 100 kHz with 10× gain margin |
| Input offset voltage | ±0.3 mV (typ) - ensures ≤0.6 mV error in unidirectional current sensing at 100 mV full-scale |
| Quiescent current | 538 µA per amplifier - allows four-channel operation under 2.2 mA total, critical for low-power ECU modules |
| Supply range | 1.8 V to 5.5 V - compatible with 3.3 V microcontroller I/O and 5 V sensor interfaces |
| Input noise density | 10 nV/√Hz at 10 kHz - preserves SNR in 20 kHz bandwidth sensor amplification stages |
| Open-loop output impedance | 100 Ω (at 10 MHz) - simplifies stability with long PCB traces or capacitive loads up to 300 pF |
| CMRR | ≥80 dB over –40°C to +125°C - rejects common-mode transients in high-side current shunt monitoring |
Pinout & Package
TLV9064QPWRQ1 is available in two surface-mount packages: 14-pin SOIC (D) measuring 8.65 mm × 6.00 mm and 14-pin TSSOP (PW) measuring 5.00 mm × 6.40 mm. Both packages share identical pin numbering and function mapping.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplifier outputs - rail-to-rail swing supports direct interface to SAR ADCs or comparator inputs |
| 2, 6, 9, 13 | INx– | Inverting inputs - matched layout minimizes channel-to-channel offset drift in differential pairs |
| 3, 5, 10, 12 | INx+ | Noninverting inputs - high-impedance CMOS input (0.5 pA bias) avoids loading of high-Z sensor sources |
| 4 | V+ | Positive supply - accepts 1.8–5.5 V; decoupling required within 5 mm for EMI immunity |
| 11 | V– | Negative supply or ground - supports true single-supply operation down to 1.8 V |
| NC (no pin) | No internal connection | Not bonded - no routing or thermal pad connection required |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full dynamic range utilization with 1.8 V supplies-critical for low-voltage battery monitoring |
| AEC-Q100 Grade 1 qualification | Validated operation from –40°C to +125°C ambient-meets powertrain and ADAS thermal requirements |
| Internal RFI/EMI filter | Provides ≥60 dB rejection at 900 MHz-reduces need for external ferrite beads in infotainment audio paths |
| No phase reversal on overdrive | Prevents latch-up during transient overload in motor current sense feedback loops |
| Functional Safety-Capable | TI provides FIT rate data, failure mode analysis, and diagnostic coverage guidance for ISO 26262 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 |
|---|---|---|---|
| TSV914IQDT | 4-channel, 8 MHz GBW, ±1.5 mV VOS, 1.5 V to 5.5 V supply, AEC-Q100 Grade 1 | Lower bandwidth and higher offset limit use in <10 kHz sensor interfaces only | Preferred where lower cost outweighs need for 10 MHz response or sub-mV accuracy |
| LMV984QDGKRQ1 | Quad, 14 MHz GBW, ±1.25 mV VOS, 1.8 V to 5.5 V, AEC-Q100 Grade 1, no internal EMI filter | Lacks integrated RFI/EMI rejection-requires external filtering in high-noise powertrain zones | Selected when higher slew rate (10 V/µs) is prioritized over EMI robustness |

FAQ
What is the operating temperature range qualified for TLV9064QPWRQ1?
TLV9064QPWRQ1 is AEC-Q100 qualified for Grade 1 automotive operation, meaning it is specified and tested from –40°C to +125°C ambient temperature. This range covers under-hood and powertrain applications where thermal stress is highest, and all key parameters-including offset voltage drift, CMRR, and quiescent current-are guaranteed across this full interval.
Does TLV9064QPWRQ1 support single-supply operation?
Yes, TLV9064QPWRQ1 fully supports single-supply operation from 1.8 V to 5.5 V. Its rail-to-rail input and output stages allow common-mode input voltages from (V–) – 0.1 V to (V+) + 0.1 V and output swings within 20 mV of either rail at 5.5 V supply-enabling direct interfacing with 3.3 V microcontrollers and low-voltage sensors without level-shifting circuitry.
What packaging options are available for TLV9064QPWRQ1?
TLV9064QPWRQ1 is offered in two RoHS-compliant, lead-free packages: 14-pin SOIC (D) with 8.65 mm × 6.00 mm footprint and 14-pin TSSOP (PW) with 5.00 mm × 6.40 mm footprint. Both packages are qualified for automotive reflow profiles and support automated optical inspection (AOI) due to standard lead geometry and coplanarity.
How does the internal RFI/EMI filter in TLV9064QPWRQ1 improve system-level EMC?
The integrated RFI/EMI filter in TLV9064QPWRQ1 provides ≥60 dB rejection at 900 MHz and >40 dB suppression across 100 MHz–2 GHz-reducing susceptibility to cellular, Bluetooth, and radar band interference. This eliminates the need for discrete RC filters in infotainment audio paths and improves conducted emissions margins in ADAS domain controllers without increasing BOM count.
Is TLV9064QPWRQ1 pin-compatible with non-automotive TLV9064 variants?
No-TLV9064QPWRQ1 is not pin-compatible with commercial-grade TLV9064 variants. While both share identical pin functions and SOIC/TSSOP footprints, the Q1 version includes enhanced ESD protection (HBM ±4 kV), tighter parametric screening, and automotive-specific reliability testing. Layout reuse is possible, but qualification and thermal validation must be repeated for automotive deployment.
