Product details
Overview
TLV9352QPWRQ1 from Texas Instruments is a dual-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier optimized for cost-sensitive high-voltage systems. It delivers rail-to-rail output swing, ±350 µV max input offset voltage, ±1.5 µV/°C offset drift, 3.5 MHz gain-bandwidth, and 20 V/µs slew rate - enabling precision signal conditioning in HEV/EV motor control current sensing and ADAS sensor interfaces.
For engineers reviewing the TLV9352QPWRQ1 datasheet, TLV9352QPWRQ1 pinout, TLV9352QPWRQ1 application, or TLV9352QPWRQ1 equivalent, key selection criteria include its MUX-friendly input architecture (±40 V differential input range), robust 71–94 dB EMIRR performance across 400 MHz–5 GHz, and ±60 mA output drive capability under automotive temperature range (–40°C to +125°C).
Technical Context
The TLV9352QPWRQ1 employs a patented input protection architecture eliminating conventional back-to-back diodes, enabling full 40 V differential input voltage without settling distortion - critical for multiplexed sensor front-ends. Its Class AB output stage supports ±60 mA sourcing/sinking while maintaining rail-to-rail output swing down to 5 mV from rails at no load.
It features integrated EMI filtering on both inputs, delivering verified EMIRR of 90 dB at 2.4 GHz and 94 dB at 5 GHz - directly addressing interference from Bluetooth®, Wi-Fi, and cellular bands in infotainment and ADAS modules. The device operates from 4.5 V to 40 V single supply or ±2.25 V to ±20 V dual supply.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM7332QMA/NOPB | Wider supply (±16 V), higher IQ (2.3 mA), no integrated EMI filters, lower GBW (20 MHz) | Targeted at general-purpose industrial amps; not AEC-Q100 qualified | Choose only if higher bandwidth and rail-to-rail I/O are required and EMI immunity is managed externally |
| TSV912AQDRQ1 | Lower supply (5.5 V max), lower IQ (85 µA), no MUX-friendly inputs, 8 MHz GBW | Optimized for ultra-low-power body electronics; insufficient for 40 V HEV systems | Select when operating from 3.3 V/5 V rails and EMI environment is benign; unsuitable for high-voltage current sensing |
Compared with LM7332QMA/NOPB and TSV912AQDRQ1, the TLV9352QPWRQ1 uniquely combines 40 V operation, AEC-Q100 Grade 1 qualification, MUX-compatible inputs, and industry-leading 94 dB EMIRR - making it the only option qualified for safety-critical HEV/EV inverter current feedback loops.

FAQ
What is the maximum differential input voltage specification for TLV9352QPWRQ1?
The TLV9352QPWRQ1 supports a maximum differential input voltage of ±40 V - meaning the voltage difference between IN+ and IN– pins can safely reach 40 V without damage or phase reversal. This is enabled by its patented input architecture and makes TLV9352QPWRQ1 suitable for comparator use and high-dV/dt multiplexed sensor applications, unlike conventional op amps limited to ~0.7 V differential range.
Does TLV9352QPWRQ1 support single-supply operation, and what is the minimum supply voltage?
Yes, TLV9352QPWRQ1 supports true single-supply operation from 4.5 V to 40 V. At 4.5 V, it maintains rail-to-rail output swing (20–75 mV headroom into 2 kΩ), 3.5 MHz GBW, and 15 nV/√Hz input voltage noise. This allows direct integration into 12 V automotive systems without intermediate regulation - reducing BOM cost and board space versus dual-supply alternatives.
How does the EMI rejection performance of TLV9352QPWRQ1 benefit automotive designs?
TLV9352QPWRQ1 delivers 90 dB EMIRR at 2.4 GHz and 94 dB at 5 GHz - measured per TI's standardized methodology - directly suppressing interference from Bluetooth®, Wi-Fi 5/6, and cellular transceivers co-located on infotainment or telematics PCBs. This eliminates need for external RC filters or ferrite beads in sensitive analog paths, simplifying layout and improving system-level EMC test pass rates without sacrificing bandwidth.
What package options are available for TLV9352QPWRQ1, and is the PW package RoHS-compliant?
TLV9352QPWRQ1 is offered exclusively in the 8-pin TSSOP (PW) package (3.0 mm × 6.4 mm). This package is lead-free, RoHS-compliant, and qualified to AEC-Q100 Grade 1. Thermal resistance RθJA is 185.1°C/W - validated for operation at 125°C ambient in engine bay or power distribution modules with standard 2-layer PCB copper pour.
Can TLV9352QPWRQ1 be used in open-loop mode as a comparator, and what are the limitations?
Yes, TLV9352QPWRQ1 is explicitly designed for open-loop use as a comparator due to its MUX-friendly inputs and absence of phase reversal. However, propagation delay is not characterized in the datasheet, and output saturation time depends on overdrive. For precision timing-critical comparisons, a dedicated automotive comparator (e.g., TLV3604-Q1) is recommended; TLV9352QPWRQ1 excels in scenarios where analog amplification and comparator functionality share the same device to reduce component count.
