Product details
Overview
TLV9001QDCKRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive operational amplifier featuring rail-to-rail input/output, 1 MHz unity-gain bandwidth, ±0.4 mV input offset voltage, 60 µA per channel quiescent current, and operation from 1.8 V to 5.5 V supply. It serves as a precision signal-conditioning amplifier in low-side current-sensing circuits for HEV/EV motor control and ADAS sensor interfaces.
For engineers reviewing the TLV9001QDCKRQ1 datasheet, TLV9001QDCKRQ1 pinout, TLV9001QDCKRQ1 application, or TLV9001QDCKRQ1 equivalent, key selection criteria include its 125°C ambient rating, resistive open-loop output impedance enabling stable drive of ≥500 pF capacitive loads, integrated RFI/EMI filtering, and functional safety capability documentation per ISO 26262.
Technical Context
The TLV9001QDCKRQ1 employs a complementary N/P-channel input stage enabling true rail-to-rail common-mode input range (V– – 0.1 V to V+ + 0.1 V) across 1.8 V–5.5 V supplies. Its class-AB output stage delivers rail-to-rail swing-within 20 mV of rails at 10 kΩ load-and exhibits resistive open-loop output impedance (~1.2 kΩ at 1 MHz), simplifying stability with high capacitive loads.
It achieves unity-gain stability without external compensation, features no phase reversal under overdrive, and integrates on-die RFI/EMI rejection filters. Electrical performance is specified over –40°C to +125°C, with input bias current ≤5 pA, input voltage noise density of 27 nV/√Hz at 10 kHz, and PSRR ≥80 dB across supply range.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV9001DRBRQ1 | Same electrical specs; packaged in 5-pin SON (DRB), 1.5 mm × 2.0 mm footprint - 0.25 mm wider than DCK | SON offers better thermal dissipation (RθJA = 190.2°C/W vs 239.6°C/W) but requires different land pattern | Select DRBRQ1 for higher-power-density layouts where board space permits larger pad geometry |
| LMV931QDBVRQ1 | Lower GBW (1.5 MHz), higher IQ (130 µA), same AEC-Q100 Grade 1 rating; no integrated EMI filter | Higher speed but less suitable for ultra-low-power always-on sensing; lacks RFI rejection for noisy powertrain environments | Choose LMV931QDBVRQ1 only when bandwidth >1 MHz is required and EMI immunity is managed externally |
Compared with TLV9001DRBRQ1 and LMV931QDBVRQ1, TLV9001QDCKRQ1 provides optimal balance of ultra-low quiescent current (60 µA), integrated EMI filtering, and SC70 footprint-making it the preferred choice for space- and power-constrained automotive sensing nodes requiring robust EMC performance.

FAQ
What is the maximum capacitive load the TLV9001QDCKRQ1 can drive while maintaining stability?
The TLV9001QDCKRQ1 is characterized to drive ≥500 pF capacitive loads stably in unity-gain configuration due to its resistive open-loop output impedance. This eliminates the need for series isolation resistors when interfacing with ADC inputs or long PCB traces-unlike many general-purpose op amps that require external compensation above 100 pF.
Does the TLV9001QDCKRQ1 support single-supply operation at 1.8 V?
Yes, TLV9001QDCKRQ1 operates from 1.8 V to 5.5 V and is fully specified at 1.8 V, including rail-to-rail input/output swing, 1 MHz bandwidth, and 60 µA quiescent current. Its input common-mode range extends 0.1 V beyond both rails, enabling true single-supply functionality without level shifters or bias networks.
How does the integrated RFI/EMI filter in the TLV9001QDCKRQ1 improve system-level EMC performance?
The TLV9001QDCKRQ1 incorporates on-die RFI/EMI rejection filtering that attenuates high-frequency interference (e.g., from DC-DC converters or RF transceivers) before it reaches the input stage. Measured EMIRR+ exceeds 100 dB at 100 MHz, reducing susceptibility without requiring external RC filters or ferrite beads-simplifying layout and improving reliability in noisy automotive environments.
Is the TLV9001QDCKRQ1 pin-compatible with other members of the TLV900x-Q1 family?
No-TLV9001QDCKRQ1 (single-channel, SC70-5) is not pin-compatible with TLV9002-Q1 (dual, SOIC-8/TSSOP-8) or TLV9004-Q1 (quad, SOIC-14). However, its SC70-5 pinout matches TLV9001DRBRQ1 (SON-5) only in function-not mechanical layout-requiring PCB redesign for package substitution.
What functional safety documentation is provided for the TLV9001QDCKRQ1?
Texas Instruments provides functional safety documentation for TLV9001QDCKRQ1 including FIT rate (112 failures per billion hours), failure mode effects analysis (FMEA), and diagnostic coverage guidance aligned with ISO 26262 ASIL-B requirements. This supports integration into safety-critical automotive systems such as battery management and ADAS actuator control.
