Product details
Overview
TLV9354QDYYRQ1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier with rail-to-rail output, 3.5MHz gain-bandwidth, ±60mA output drive, and ±350µV max input offset voltage. It operates from 4.5V to 40V supply and supports differential input voltages up to the full supply rail-enabling robust use in high-voltage current sensing and multiplexer-friendly signal conditioning circuits within ADAS and powertrain systems.
For engineers reviewing the TLV9354QDYYRQ1 datasheet, TLV9354QDYYRQ1 pinout, TLV9354QDYYRQ1 application, or TLV9354QDYYRQ1 equivalent, key selection considerations include its MUX-friendly input architecture, EMI-hardened inputs (94dB EMIRR at 5GHz), low 600µA per-amplifier quiescent current, and guaranteed operation from –40°C to 125°C in automotive environments.
Technical Context
The TLV9354QDYYRQ1 implements a patented input protection architecture that eliminates conventional back-to-back clamping diodes, enabling true 40V differential input swing without settling distortion-critical for fast-switching multichannel sensor interfaces. Its Class AB output stage delivers ±60mA drive into resistive loads while maintaining rail-to-rail output swing down to 5mV from rails at no load.
Internally, the device integrates EMI filtering on both inputs, achieving ≥71dB EMIRR across 400MHz–5GHz bands, and features a stable unity-gain-compensated design with 60° phase margin and 300pF capacitive load drive capability-supporting direct connection to long traces or noisy PCB nodes without external isolation.
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 |
|---|---|---|---|
| LM2902QDRQ1 | Lower bandwidth (1.2MHz), higher offset (±3mV), no EMI filtering, 700µA per amp | Cost-sensitive non-safety-critical body electronics only; not suitable for ADAS or high-speed sensing | Select when budget constraints outweigh performance needs and EMI immunity is not required |
| TSV914IQDT | Higher bandwidth (8MHz), lower noise (12nV/√Hz), but only 20V max supply and no AEC-Q100 Grade 1 rating | Limited to 12V systems and non-automotive industrial applications; lacks automotive qualification | Choose for higher-speed signal chains where 40V operation and AEC-Q100 are not mandatory |
Compared with LM2902QDRQ1 and TSV914IQDT, TLV9354QDYYRQ1 uniquely combines 40V operation, AEC-Q100 Grade 1 qualification, EMI-hardened inputs, and MUX-friendly architecture-making it the only option qualified for high-reliability, high-voltage automotive sensing where signal integrity under RF stress is critical.

FAQ
What is the maximum differential input voltage specification for TLV9354QDYYRQ1?
The TLV9354QDYYRQ1 supports a maximum differential input voltage of up to 40V-equal to its full supply range-enabled by its patented input architecture without clamping diodes. This allows safe operation when inputs swing beyond rails, such as during multiplexer channel switching or fault conditions. This specification is validated across –40°C to 125°C and is explicitly stated in Section 5.1 Absolute Maximum Ratings of the TLV9354QDYYRQ1 datasheet.
Does TLV9354QDYYRQ1 support single-supply operation, and what is the minimum recommended supply voltage?
Yes, TLV9354QDYYRQ1 supports true single-supply operation from 4.5V to 40V, with V– connected to ground. The minimum recommended supply is 4.5V per Section 5.3 Recommended Operating Conditions, ensuring full functionality including rail-to-rail output swing and specified AC performance. Operation below 4.5V may result in degraded bandwidth, increased offset, or failure to meet AEC-Q100 Grade 1 thermal specifications.
What is the thermal resistance (RθJA) of TLV9354QDYYRQ1 in its DYY package?
The TLV9354QDYYRQ1 in the 14-pin SOT-23 (DYY) package has a junction-to-ambient thermal resistance (RθJA) of 110.7°C/W, as specified in Section 5.6 Thermal Information for Quad Channel. This value assumes standard JEDEC 2-layer board conditions and is critical for calculating maximum allowable power dissipation at 125°C ambient-enabling reliable operation in engine bay or power module locations.
Can TLV9354QDYYRQ1 be used as a comparator, and what design considerations apply?
Yes, TLV9354QDYYRQ1 can be used open-loop as a comparator due to its MUX-friendly inputs, rail-to-rail output, and ability to handle differential inputs up to the supply rails. However, it lacks internal hysteresis and has slower propagation delay than dedicated comparators. For TLV9354QDYYRQ1, external hysteresis must be added via positive feedback, and output loading should remain ≤10kΩ to maintain speed. Its 20V/µs slew rate limits response to ~50ns for 1V transitions.
What packaging and tape-and-reel options are available for TLV9354QDYYRQ1?
TLV9354QDYYRQ1 is offered exclusively in the 14-pin SOT-23 (DYY) package, supplied in tape-and-reel format per TI's orderable addendum: 3,000 units per reel (orderable part number TLV9354QDYYRQ1). No tray or tube options are available for this variant. The DYY package footprint is 4.2mm × 3.26mm with 0.65mm pitch, compatible with standard SMT assembly processes and IPC-7351B naming conventions.
