Product details
Overview
TLV9064QDRQ1 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 channel. It operates from 1.8 V to 5.5 V and delivers low broadband noise (10 nV/√Hz), making it suitable for precision signal conditioning in HEV/EV motor control current sensing and ADAS sensor interfaces.
For engineers reviewing the TLV9064QDRQ1 datasheet, TLV9064QDRQ1 pinout, TLV9064QDRQ1 application, or TLV9064QDRQ1 equivalent, key selection criteria include its automotive qualification (–40°C to +125°C), resistive open-loop output impedance for stable high-capacitive-load driving, integrated RFI/EMI filtering, and functional safety documentation support.
Technical Context
The TLV9064QDRQ1 implements a CMOS input stage with unity-gain stability across its full supply range (1.8 V–5.5 V) and features no phase reversal under overdrive. Its resistive open-loop output impedance simplifies compensation with capacitive loads up to 100 pF and beyond-unlike typical op amps requiring external isolation resistors.
It integrates internal RFI and EMI rejection filters, supports single-supply operation with rail-to-rail common-mode input range (V– – 0.1 V to V+ + 0.1 V), and maintains ≥80 dB CMRR over –40°C to +125°C at 5.5 V supply-critical for noisy automotive environments.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-sensor signal conditioning or multi-stage filtering on single IC |
| Unity-gain bandwidth | 10 MHz - supports fast transient response in motor current feedback loops and ADAS analog front-ends |
| Input offset voltage | ±0.3 mV (typ) - ensures <1% error in 300-mV full-scale current-sense applications without trimming |
| Quiescent current | 538 µA per channel - allows four amplifiers to operate within 2.2 mA total, ideal for always-on vehicle subsystems |
| Supply voltage range | 1.8 V to 5.5 V - compatible with 3.3-V microcontrollers and 5-V legacy automotive rails |
| Input voltage noise | 10 nV/√Hz at 10 kHz - preserves SNR in low-level sensor amplification (e.g., shunt-based current sensing) |
| Open-loop output impedance | 100 Ω (at 10 MHz) - enables direct drive of >100-pF loads without external series resistor, reducing BOM count |
Pinout & Package
TLV9064QDRQ1 is packaged in a 14-pin SOIC (D package), 8.65 mm × 6.00 mm body size, with standard lead pitch and surface-mount compatibility.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplifier outputs - rail-to-rail swing supports full dynamic range utilization in single-supply systems |
| 2, 6, 9, 13 | IN1– – IN4– | Inverting inputs - matched layout minimizes channel-to-channel offset drift in differential configurations |
| 3, 5, 10, 12 | IN1+ – IN4+ | Noninverting inputs - rail-to-rail common-mode range (V– – 0.1 V to V+ + 0.1 V) enables direct connection to sensors near supply rails |
| 4 | V+ | Positive supply - accepts 1.8–5.5 V; decoupling required within 1 cm for EMI robustness |
| 11 | V– | Negative supply or ground - supports true single-supply operation with GND reference |
| No Connect (NC) | Not bonded | No internal connection - must be left floating; not usable as thermal pad or auxiliary terminal |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Enables full utilization of 1.8-V to 5.5-V supply rails for maximum signal swing in low-voltage automotive domains |
| AEC-Q100 Grade 1 | Qualified for –40°C to +125°C ambient operation - meets thermal requirements for engine bay and powertrain locations |
| Integrated RFI/EMI filter | Rejects >60 dB of RF interference up to 1 GHz - eliminates need for external ferrite beads in infotainment and ADAS modules |
| No phase reversal | Prevents output latch-up during input overdrive - critical for fault-tolerant current-sense circuits in OBC and inverter controls |
| Functional Safety-Capable | Documentation available for ISO 26262 ASIL-B system integration - reduces FMEDA effort for safety-critical ECUs |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV934QDRQ1 | Lower bandwidth (1.5 MHz), higher offset (±3.5 mV), same AEC-Q100 Grade 1, SOIC-14 package | Less suitable for >100-kHz closed-loop control; acceptable for slow-varying sensor signals (e.g., cabin temperature) | Choose when cost sensitivity outweighs bandwidth and precision needs; verify loop stability at reduced GBP |
| TSV914IQDRQ1 | Higher offset (±1.5 mV), lower noise (14 nV/√Hz), same 10-MHz GBP, identical SOIC-14 footprint | Acceptable for mid-precision ADAS camera biasing but not for sub-0.5% current sensing | Prefer when EMI immunity is secondary and lower input bias current (1 pA) is prioritized over offset voltage |
Compared with LMV934QDRQ1 and TSV914IQDRQ1, TLV9064QDRQ1 provides superior DC precision (±0.3 mV vs ±1.5–3.5 mV) and higher bandwidth, enabling tighter control loops in motor drives and faster settling in radar signal chains-without changing PCB layout.

FAQ
What is the operating temperature range for TLV9064QDRQ1?
TLV9064QDRQ1 is qualified per AEC-Q100 Grade 1 with a specified ambient operating temperature range of –40°C to +125°C. This rating is validated across all electrical parameters in the datasheet and applies to the SOIC (D) package variant. Thermal derating is not required within this range when mounted per JEDEC standards with recommended PCB copper area.
Does TLV9064QDRQ1 support single-supply operation?
Yes, TLV9064QDRQ1 fully supports single-supply operation. Its rail-to-rail input common-mode range extends from V– – 0.1 V to V+ + 0.1 V, and its rail-to-rail output swing reaches within 20 mV of both supply rails at 5.5 V with 10-kΩ load. This allows direct interfacing with sensors and MCUs referenced to ground in 3.3-V or 5-V automotive systems.
What is the shutdown functionality of TLV9064QDRQ1?
TLV9064QDRQ1 does not include a shutdown pin. The shutdown feature is only available in the TLV906xS-Q1 variants (e.g., TLV9064SQDRQ1). TLV9064QDRQ1 operates continuously when powered; for power-gated applications, external enable circuitry or supply switching must be used.
Is TLV9064QDRQ1 pin-compatible with other TLV906x-Q1 family members?
No-TLV9064QDRQ1 (SOIC-14) is not pin-compatible with TLV9061-Q1 (SOT-23-5/SC70-5) or TLV9062-Q1 (SOIC-8/TSSOP-8/VSSOP-8). Pin counts, channel count, and pin assignments differ fundamentally. However, electrical specifications and functional behavior are consistent across the family, enabling schematic reuse with layout adaptation.
How does TLV9064QDRQ1 handle capacitive loads?
TLV9064QDRQ1 features a resistive open-loop output impedance (~100 Ω), which significantly improves stability with capacitive loads compared to conventional op amps. It remains unity-gain stable with ≥100 pF loads and exhibits <10% overshoot up to 300 pF-enabling direct connection to ADC input capacitors or long PCB traces without isolation resistors.
