Product details
Overview
TLV9162QDGKRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, ±210 µV offset voltage, 11 MHz gain-bandwidth product, and 33 V/µs slew rate - deployed in high-side current sensing and ADAS signal conditioning circuits operating from –40°C to +125°C.
For engineers reviewing the TLV9162QDGKRQ1 datasheet, TLV9162QDGKRQ1 pinout, TLV9162QDGKRQ1 application, or TLV9162QDGKRQ1 equivalent, this page delivers verified electrical specs, package-validated pin functions, automotive-grade ESD/EMI performance data, and real-world current-sensing implementation context - all aligned to TI's SBOSAD7A (August 2024) production datasheet.
Technical Context
The TLV9162QDGKRQ1 implements a patented MUX-friendly front-end architecture enabling full 16-V differential input voltage tolerance without clamping diodes - eliminating transient-induced settling delays in multiplexed sensor interfaces. Its dual-channel layout supports independent high-precision signal paths with matched DC characteristics across temperature.
It integrates robust EMI rejection circuitry optimized for automotive environments, achieving >70 dB EMIRR at 1 GHz while maintaining 110 dB CMRR at DC and 85 dB over –40°C to +125°C. The device operates from 2.7 V to 16 V supply, supports rail-to-rail output swing within 6 mV of rails (no-load, 16 V), and delivers ±73 mA short-circuit current per channel.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2991QDGKRQ1 | Lower offset (±125 µV typ), lower noise (5.5 nV/√Hz), but 4.2 MHz GBW and 15 V max supply. | Better DC precision for ultra-low-current sensing; insufficient bandwidth for >200 kHz OBC feedback loops. | Select when offset and noise dominate over speed; avoid where 11 MHz GBW is required for transient response. |
| LM7322QMA/NOPB | Higher quiescent current (2.8 mA/ch vs 2.4 mA), wider offset range (±3 mV max), no AEC-Q100 Grade 1 certification. | Not qualified for powertrain or ADAS; suitable only for non-safety-critical body electronics. | Use only in cost-sensitive, non-automotive-qualified subsystems; not acceptable for ISO 26262 ASIL-B designs. |
Compared with OPA2991QDGKRQ1 and LM7322QMA/NOPB, TLV9162QDGKRQ1 uniquely balances 11 MHz bandwidth, AEC-Q100 Grade 1 qualification, and ±210 µV offset - making it the only option qualified for high-speed, safety-critical current sensing in EV inverters and ADAS radar receivers.

FAQ
What is the maximum differential input voltage specification for TLV9162QDGKRQ1?
The TLV9162QDGKRQ1 supports a maximum differential input voltage of 16 V - enabled by its patented MUX-friendly input architecture that eliminates conventional clamping diodes. This allows direct connection to high-swing sensor outputs or use as a comparator without external protection components, as confirmed in Section 6.3.1 of the SBOSAD7A datasheet.
Does TLV9162QDGKRQ1 support single-supply operation?
Yes, TLV9162QDGKRQ1 operates from a single supply of 2.7 V to 16 V, with rail-to-rail input and output capability. At 2.7 V supply, it maintains 5 mV output headroom into 10 kΩ load, enabling direct interfacing with low-voltage automotive MCUs - verified under Recommended Operating Conditions (Section 5.3) and Output specifications (Section 5.7).
What is the thermal resistance (RθJA) of TLV9162QDGKRQ1 in the DGK package?
The TLV9162QDGKRQ1 in the 8-pin VSSOP (DGK) package has a junction-to-ambient thermal resistance (RθJA) of 173.9 °C/W, as specified in Section 5.5 of the SBOSAD7A datasheet. This value assumes standard JEDEC PCB mounting conditions and informs heatsinking requirements for continuous 2.4 mA/ch operation at 125°C ambient.
Is TLV9162QDGKRQ1 qualified for ASIL-B functional safety applications?
TLV9162QDGKRQ1 is AEC-Q100 Grade 1 qualified (–40°C to +125°C) and features documented failure-in-time (FIT) rates, parametric stability over temperature, and robust ESD/EMI performance - forming foundational elements for ASIL-B system compliance. However, final ASIL-B qualification requires integration-level analysis per ISO 26262; TI provides FIT data and safety manuals to support that effort.
How does the EMIRR performance of TLV9162QDGKRQ1 compare to standard op amps in automotive environments?
TLV9162QDGKRQ1 achieves >70 dB electromagnetic interference rejection ratio (EMIRR) at 1 GHz - significantly exceeding typical automotive op amps (<50 dB). This is achieved via integrated on-die filtering, as shown in Figure 5-40 of SBOSAD7A, and directly improves immunity to LTE/cellular noise in infotainment and ADAS signal chains without external RC filters.
