Product details
Overview
TLV9354QDRQ1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier optimized for cost-sensitive high-voltage systems. It delivers rail-to-rail output, ±350 µV max input offset voltage, 3.5 MHz gain-bandwidth, 20 V/µs slew rate, and ±60 mA output drive - enabling precision current sensing and signal conditioning in HEV/EV motor control and ADAS sensor interfaces.
For engineers reviewing the TLV9354QDRQ1 datasheet, TLV9354QDRQ1 pinout, TLV9354QDRQ1 application, or TLV9354QDRQ1 equivalent, key selection criteria include its MUX-friendly inputs (full 40 V differential input range), robust 71–94 dB EMIRR performance across 400 MHz–5 GHz, low 650 µA per-amplifier quiescent current, and operation from –40°C to 125°C ambient.
Technical Context
The TLV9354QDRQ1 implements a patented input architecture that eliminates conventional back-to-back diode clamps, enabling true 40 V differential input voltage tolerance without settling delay or distortion - critical for multichannel multiplexed sensor front-ends. Its Class AB output stage supports ±60 mA sourcing/sinking into resistive or capacitive loads up to 300 pF.
It features integrated EMI filtering on both inputs, delivering 94 dB EMIRR at 5 GHz and ≥80 dB from 900 MHz–2.4 GHz - directly addressing interference from GSM, Bluetooth®, and Wi-Fi coexistence in automotive ECUs. The device operates with supply voltages from 4.5 V to 40 V (±2.25 V to ±20 V) and maintains 110 dB CMRR over temperature.

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM2902QDRQ1 | Lower GBW (1.2 MHz), higher offset (±3 mV), no MUX-friendly inputs, no EMI filtering | Cost-optimized analog cluster gauges where RF immunity and precision are secondary | Choose when budget constraints outweigh need for radar-grade EMI rejection or fast current loop response |

FAQ
What is the maximum differential input voltage supported by TLV9354QDRQ1?
TLV9354QDRQ1 supports a maximum differential input voltage of 40 V - meaning the voltage difference between any IN+ and IN– pin can reach the full supply rail span (e.g., 40 V in single-supply mode). This is enabled by its patented input architecture without clamping diodes, allowing safe use in comparator configurations and multiplexed high-voltage sensor interfaces without external protection.
Does TLV9354QDRQ1 require external compensation for unity-gain stability?
No, TLV9354QDRQ1 is internally compensated for unity-gain stability. Its 3.5 MHz gain-bandwidth product and 60° phase margin at G = +1 ensure stable operation with capacitive loads up to 300 pF without added external components - simplifying layout in space-constrained automotive PCBs.
How does TLV9354QDRQ1 handle electromagnetic interference in radar applications?
TLV9354QDRQ1 integrates on-chip RC filters on both inputs, achieving 94 dB EMIRR at 5 GHz - directly suppressing interference from 802.11a/n Wi-Fi co-located in domain controllers. This prevents RF rectification and baseline shift in 77 GHz radar IF amplifiers, maintaining signal integrity without additional shielding or ferrite beads.
What is the output voltage swing capability of TLV9354QDRQ1 at 40 V supply?
At VS = 40 V and RL = 10 kΩ, TLV9354QDRQ1 delivers rail-to-rail output swing with ≤55 mV headroom to each rail. Under no-load conditions, headroom drops to 5–10 mV. This enables direct interfacing with 12-bit SAR ADCs and low-voltage logic without level-shifting circuitry in high-side current sensing topologies.
Is TLV9354QDRQ1 pin-compatible with other quad op amps in SOIC-14 packages?
No, TLV9354QDRQ1 uses a proprietary pinout optimized for automotive layout: V+ is on pin 4 and V– on pin 11, differing from industry-standard SOIC-14 op amp placements (e.g., LM2902). Direct replacement requires PCB redesign; migration paths must account for supply pin relocation and absence of shutdown or enable pins.
