Product details
Overview
TLV9004QDYYRQ1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, 1MHz unity-gain bandwidth, ±0.4mV max input offset voltage, and 60µA per channel quiescent current. It operates from 1.8V to 5.5V and delivers robust performance in low-side current sensing, ADAS sensor signal conditioning, and infotainment audio front-ends.
For engineers reviewing the TLV9004QDYYRQ1 datasheet, TLV9004QDYYRQ1 pinout, TLV9004QDYYRQ1 application, or TLV9004QDYYRQ1 equivalent, this page provides verified electrical specifications, validated SOT-23-14 pin mapping, automotive-grade thermal metrics (RθJA = 154.3°C/W), functional safety capability documentation, and direct alternative part comparisons for production design-in.
Technical Context
The TLV9004QDYYRQ1 implements a complementary N/P-channel input stage enabling true rail-to-rail common-mode input range (V– – 0.1V to V+ + 0.1V) across 1.8V–5.5V supplies. Its resistive open-loop output impedance (1200Ω at 1MHz) simplifies stability with capacitive loads up to 500pF without external compensation.
It features integrated RFI/EMI filtering (EMIRR+ > 100dB at 100MHz), no phase reversal under overdrive, and unity-gain stability. Electrical behavior is characterized across –40°C to +125°C with guaranteed parameters including ±2mV max offset voltage, 86–95dB CMRR, and 78° phase margin at G = 1.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-sensor signal conditioning or multi-stage filtering in single-package layout |
| Unity-gain bandwidth | 1MHz - supports stable closed-loop operation up to ~100kHz with gain ≥10, suitable for motor current feedback and battery monitoring |
| Input offset voltage | ±0.4mV (typ), ±2mV (max, –40°C to +125°C) - ensures ≤200µV error in 50mV shunt-based current sensing at full temperature range |
| Quiescent current | 60µA per channel - enables always-on sensor interfaces in automotive body control modules with <250µA total supply draw |
| Supply voltage range | 1.8V to 5.5V - compatible with 3.3V microcontroller I/O domains and 5V analog subsystems without level-shifting |
| Output swing | Within 20mV of rails (RL = 10kΩ) - maximizes dynamic range for ADC drivers operating near supply limits |
| Capacitive load drive | Stable with up to 500pF - eliminates need for isolation resistors when driving long traces or ADC input capacitance |
Pinout & Package
SOT-23-14 (DYY) package: 4.20mm × 1.90mm footprint, 0.65mm pitch, thermally enhanced for automotive ambient conditions (RθJA = 154.3°C/W).
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplifier outputs - each drives independent load; rail-to-rail swing enables direct connection to SAR ADC inputs |
| 2, 6, 9, 13 | IN1––IN4– | Inverting inputs - used in transimpedance, difference, or inverting gain configurations |
| 3, 5, 10, 12 | IN1+–IN4+ | Noninverting inputs - accept signals from sensors or reference sources across full supply rail range |
| 4 | V+ | Positive supply - accepts 1.8V–5.5V; decoupling capacitor required within 1cm for EMI immunity |
| 11 | V– | Negative supply / ground - supports single-supply (V– = GND) or split-rail operation |
| No pin | NC | No internal connection - pin 11 is V–; pins not listed as NC in Table 5-3 are functional |
Key Features
| Feature | Design Value |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9004QDRQ1 | SOIC-14 package (8.65mm × 3.91mm); RθJA = 115.1°C/W; higher thermal mass but larger PCB area | Better thermal performance in convection-cooled modules; less suitable for space-constrained ADAS camera housings | Select TLV9004QDRQ1 when board-level airflow is limited and thermal derating margin is critical. |
| LMV334QDGKRQ1 | Lower GBW (1.2MHz vs 1MHz), higher IQ (80µA vs 60µA), no integrated EMI filter, same AEC-Q100 Grade 1 | Acceptable for non-EMI-sensitive body electronics; unsuitable for infotainment or radar where RFI rejection is mandatory | Choose LMV334QDGKRQ1 only if EMI immunity is not required and marginal bandwidth increase justifies higher quiescent current. |
Compared with TLV9004QDRQ1 and LMV334QDGKRQ1, TLV9004QDYYRQ1 uniquely balances ultra-small SOT-23-14 footprint, industry-leading EMI rejection, and lowest quiescent current in its AEC-Q100 quad op amp class-making it optimal for thermally constrained, noise-sensitive automotive sensors.

FAQ
What is the maximum capacitive load the TLV9004QDYYRQ1 can drive while maintaining stability?
The TLV9004QDYYRQ1 is characterized for stable operation with up to 500pF capacitive load without external compensation. Its resistive open-loop output impedance (1200Ω at 1MHz) and 78° phase margin at unity gain enable robust drive into ADC input capacitance or long PCB traces. For loads exceeding 500pF, TI recommends verifying stability using the small-signal step response test in Figure 6-29 of the SBOS980G datasheet.
Does the TLV9004QDYYRQ1 support single-supply operation at 1.8V?
Yes, the TLV9004QDYYRQ1 fully supports single-supply operation from 1.8V to 5.5V. At 1.8V, it maintains rail-to-rail input (V– – 0.1V to V+ + 0.1V) and output swing (within 35mV of rails at RL = 2kΩ), 1MHz gain-bandwidth, and 60µA per channel quiescent current. All key specs-including PSRR (80dB), CMRR (68dB), and offset voltage (±1.85mV typ)-are guaranteed across this voltage range.
How does the TLV9004QDYYRQ1 handle overdrive conditions without phase reversal?
The TLV9004QDYYRQ1 uses a complementary input stage architecture that prevents phase reversal during overdrive. When input voltages exceed the common-mode range, both N- and P-channel differential pairs remain active in transition regions, avoiding latch-up or polarity inversion. This is confirmed in Figure 6-27 of the SBOS980G datasheet, which shows clean recovery from 6.5Vpp overdrive with no output polarity flip.
Is the TLV9004QDYYRQ1 pin-compatible with other TLV900x-Q1 variants?
No, the TLV9004QDYYRQ1 in SOT-23-14 (DYY) is not pin-compatible with TLV9004QDRQ1 (SOIC-14) or TLV9004QPWRQ1 (TSSOP-14). While all share identical electrical functionality and pin numbering per Table 5-3, the DYY package has different mechanical layout, thermal pad absence, and solder mask requirements. PCB redesign is required when substituting between packages.
What functional safety documentation is available for the TLV9004QDYYRQ1?
Texas Instruments provides functional safety-capable documentation for the TLV9004QDYYRQ1, including FIT rate calculation (126.5 FIT), failure mode effects analysis (FMEA), and diagnostic coverage guidance for ISO 26262 ASIL-B compliance. These materials are accessible via TI's Functional Safety Information portal (SPNQ-001) and referenced in Section 1 of the SBOS980G datasheet under "Functional Safety-Capable".
