Key Features
- Rail-to-rail output with 40 V supply range supports direct 12 V and 24 V automotive rail signal conditioning without resistive dividers
- 3.5 MHz gain-bandwidth product and 95 dB minimum CMRR enable precise amplification of small differential sensor signals in noisy vehicle environments
- AEC-Q100 Grade 1 qualified, operating from -40°C to +125°C with MUX-friendly inputs for multiplexed sensor scanning without output phase inversion
Applications
The TLV9351QDBVRQ1 is used in automotive sensor signal conditioning chains for current sensing, temperature measurement, and position sensing in ADAS, powertrain, and chassis systems. Its MUX-friendly input stage allows the op amp output to recover cleanly when the input is rapidly switched between multiple sensor channels, a critical requirement in multiplexed ECU analog front ends. The 5-pin SOT-23 package conserves PCB space in compact sensor modules where multiple amplifier channels must fit within a few square millimeters.

Frequently Asked Questions
What supply voltage range does TLV9351QDBVRQ1 support and can it operate directly from a 12 V automotive battery rail?
The TLV9351QDBVRQ1 operates from a supply voltage range of 1.8 V to 40 V, making it fully compatible with 12 V automotive battery rails and 24 V truck electrical systems without additional regulation. Its rail-to-rail output swings within 100 mV of either supply rail, maximizing the usable signal range across the full 40 V window.
How does the MUX-friendly input architecture of TLV9351QDBVRQ1 benefit multiplexed sensor scanning in an automotive ECU?
The MUX-friendly input design prevents output phase reversal when the input voltage briefly exceeds the supply voltage during multiplexer switching transitions, a condition that occurs in 5 µs to 10 µs windows as the MUX selects new channels. This eliminates false readings in 8-channel sensor scans and simplifies ECU firmware by removing need for recovery delay routines.
For a compact automotive current-sense circuit, how does the TLV9351QDBVRQ1 SOT-23 package compare to larger op-amp alternatives?
The 5-pin SOT-23 package measures approximately 1.6 mm x 2.9 mm, roughly 4 times smaller than an 8-pin SOIC, allowing up to 4 current-sense amplifier channels per square centimeter of board space. Despite its small size, it maintains 110 dB typical CMRR and 1800 µV maximum input offset voltage, meeting precision requirements for shunt-based current measurement in 12 V battery management circuits.
