Product details
Overview
TLV9164QDRQ1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, ±210 µV offset voltage, 11 MHz gain-bandwidth, and 33 V/µs slew rate. It operates from 2.7 V to 16 V supply, delivers ±73 mA short-circuit current, and supports precision current sensing in HEV/EV motor control and ADAS sensor signal conditioning.
For engineers reviewing the TLV9164QDRQ1 datasheet, TLV9164QDRQ1 pinout, TLV9164QDRQ1 application, or TLV9164QDRQ1 equivalent, this page provides verified electrical specifications, SOIC-14 and TSSOP-14 package details, automotive-grade thermal performance data (RθJA = 94.9°C/W for SOIC), and validated alternatives for high-side/low-side current sensing and infotainment audio front-end designs.
Technical Context
The TLV9164QDRQ1 implements a patented MUX-friendly front-end architecture enabling full 16 V differential input voltage tolerance without clamping diodes-critical for multiplexed sensor arrays and fast-ramping transients. Its dual-input-stage design (NCH/PCH) maintains rail-to-rail common-mode range across ±1.35 V to ±8 V supplies.
It features integrated EMI rejection circuitry optimized for automotive environments (EMIRR > 80 dB at 100 MHz), robust PSRR (110 dB at DC), and unity-gain stability with capacitive loads up to 400 pF. Channel separation exceeds –110 dB at 1 kHz, supporting simultaneous multi-signal conditioning in ADAS domain controllers.

Equivalent & Alternatives
The following parts are listed as comparable options for similar precision automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4182QDRQ1 | Lower offset (±4 µV), lower noise (5.2 nV/√Hz), but 10 MHz GBW and higher IQ (650 µA per channel). | Better for ultra-precision voltage references; less suitable for high-speed current loop closure due to lower slew rate (15 V/µs). | Select when offset drift (<0.02 µV/°C) and long-term stability outweigh speed requirements. |
| LMV881QDGKRQ1 | Higher offset (±1.2 mV), lower bandwidth (22 MHz), but lower cost and smaller SC70-5 footprint for single-channel use. | Targeted at non-critical body electronics; lacks AEC-Q100 Grade 1 temp range and MUX-friendly architecture. | Select for cost-sensitive, single-channel applications outside safety-critical domains like lighting control. |
Compared with TLV9164QDRQ1, OPA4182QDRQ1 trades speed and drive strength for nanovolt-level DC precision, while LMV881QDGKRQ1 offers compact size and cost efficiency at the expense of automotive-grade thermal robustness and differential input capability.

FAQ
What is the maximum differential input voltage supported by TLV9164QDRQ1?
TLV9164QDRQ1 supports a maximum differential input voltage of 16 V-enabled by its patented MUX-friendly input architecture that eliminates conventional clamping diodes. This allows safe operation in high-dV/dt environments such as motor phase current sensing and multiplexed battery cell monitoring without signal distortion or extended settling delays.
Does TLV9164QDRQ1 require external input protection diodes?
No, TLV9164QDRQ1 does not require external input protection diodes. Its internal architecture provides robust transient protection while maintaining full 16 V differential input range and preserving signal integrity-unlike conventional op amps that rely on diode clamps that limit differential swing and introduce settling errors.
What is the thermal performance of TLV9164QDRQ1 in SOIC-14 package?
In the SOIC-14 (D) package, TLV9164QDRQ1 has a junction-to-ambient thermal resistance (RθJA) of 94.9°C/W. This enables reliable operation at full 2.4 mA per amplifier quiescent current across −40°C to +125°C ambient, with calculated junction temperature rise of ≤228°C at worst-case 16 V supply and 4-channel load-well within the 150°C absolute maximum rating when properly heatsinked.
Can TLV9164QDRQ1 drive capacitive loads without instability?
Yes, TLV9164QDRQ1 is unity-gain stable and supports capacitive loads up to 400 pF with ≥50° phase margin, as confirmed in Figure 5-33 of the datasheet. For loads >200 pF, adding a small series isolation resistor (e.g., 50 Ω) at the output improves overshoot and settling behavior in high-impedance sensor interfaces.
How does TLV9164QDRQ1 achieve EMI immunity in automotive environments?
TLV9164QDRQ1 integrates on-die electromagnetic interference rejection (EMIRR) filtering, achieving >80 dB rejection at 100 MHz. This is implemented via dedicated internal filtering paths that attenuate RF energy from sources like LTE antennas and switching power supplies-eliminating the need for external ferrite beads or RC filters in infotainment and ADAS PCB layouts.
