Product details
Overview
TLV9354QPWRQ1 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 powertrain modules.
For engineers reviewing the TLV9354QPWRQ1 datasheet, TLV9354QPWRQ1 pinout, TLV9354QPWRQ1 application, or TLV9354QPWRQ1 equivalent, key selection criteria include its MUX-friendly input architecture (full 40 V differential input range), robust EMI rejection (94 dB at 5 GHz), low quiescent current (650–850 µA per channel), and operation across –40°C to +125°C ambient.
Technical Context
The TLV9354QPWRQ1 implements a patented input protection architecture that eliminates conventional back-to-back clamping diodes, enabling true 40 V differential input swing without settling delay or distortion - critical for multichannel multiplexed sensor interfaces. Its Class AB output stage supports ±60 mA sourcing/sinking while maintaining rail-to-rail output swing down to 10 mV from rails at 40 V supply.
EMI immunity is enhanced by integrated RF filters on both inputs, delivering ≥71 dB EMIRR from 400 MHz to 5 GHz - validated per TI's standardized test methodology. The device operates with supply voltages from 4.5 V to 40 V (±2.25 V to ±20 V) and features ±1.5 µV/°C offset drift and 15 nV/√Hz input voltage noise at 1 kHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact 4-signal conditioning in single-package space-constrained automotive ECUs. |
| Gain-bandwidth product | 3.5 MHz - supports stable closed-loop operation up to ~350 kHz at G = 10 for current-sense amplification. |
| Slew rate | 20 V/µs - ensures <5 µs 0.01% settling for 10 V step, suitable for fast transient detection in OBC and inverter control. |
| Input offset voltage | ±0.35 mV (max) - enables ≤0.5% error in 100 mΩ shunt-based current sensing at 1 A full scale. |
| Supply voltage range | 4.5 V to 40 V - covers 12 V and 24 V automotive battery systems including load-dump transients. |
| Quiescent current | 650–850 µA per channel - allows four-channel operation under 3.4 mA total, ideal for always-on ADAS subsystems. |
| EMI rejection ratio | 94 dB at 5 GHz - mitigates interference from Wi-Fi 5 GHz, LTE-A, and radar co-location in modern vehicle architectures. |
Pinout & Package
TLV9354QPWRQ1 is packaged in a 14-pin TSSOP (PW) with 5.0 mm × 6.4 mm footprint and 0.65 mm pitch. Pin functions are validated per TI SBOSA34E Rev. MARCH 2024.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplifier outputs - each drives ±60 mA, rail-to-rail swing, compatible with ADC input ranges and comparator thresholds. |
| 2, 6, 9, 13 | IN1––IN4– | Inverting inputs - support differential input up to full 40 V supply range; no external clamping required. |
| 3, 5, 10, 12 | IN1+–IN4+ | Noninverting inputs - high-impedance (6 TΩ || 1 pF), enable direct connection to resistive sensors or mux outputs. |
| 4 | V+ | Positive supply - accepts up to 40 V; internal regulation supports stable biasing across wide battery range. |
| 11 | V– | Negative supply - referenced to system ground or negative rail; supports dual-supply (±20 V) or single-supply (4.5–40 V) operation. |
Key Features
| Feature | Design Value |
|---|---|
| MUX-friendly inputs | Differential input range extends to supply rails (V– to V+), eliminating need for external level-shifting or clamping in multiplexed sensor front-ends. |
| Rail-to-rail output | Swings within 10 mV of rails at no load and 50 mV at 10 kΩ - maximizes dynamic range into 12-bit+ automotive ADCs. |
| High EMI rejection | Integrated input filters deliver 94 dB EMIRR at 5 GHz - reduces susceptibility to co-located 5G/Wi-Fi 6E without board-level shielding. |
| Low offset drift | ±1.5 µV/°C - limits temperature-induced gain error to <0.1% over –40°C to +125°C, critical for uncalibrated body electronics. |
| Open-loop comparator mode | Operates reliably in open-loop configuration with fast overload recovery (<600 ns) - enables dual-use as analog amplifier or window comparator. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LM324QPWRQ1 | Lower GBW (1.2 MHz), higher offset (±3 mV), no MUX-friendly inputs, no EMI filtering. | Limited to non-critical body electronics; unsuitable for ADAS or inverter control due to bandwidth and noise limitations. | Select when cost is primary constraint and performance requirements are relaxed (e.g., HVAC blower control). |
| TSV914IQDTQ1 | Higher offset drift (±3.5 µV/°C), lower output drive (±40 mA), no 40 V differential input capability. | Not rated for high-voltage HEV/EV applications; lacks robustness against fast-ramping multiplexer transients. | Prefer for low-voltage (≤5.5 V) sensor interfaces where EMI immunity is less critical. |

FAQ
What is the maximum differential input voltage supported by TLV9354QPWRQ1?
TLV9354QPWRQ1 supports a maximum differential input voltage of 40 V - meaning the voltage difference between IN+ and IN– pins can span the full supply range (V– to V+). This eliminates need for external clamping diodes and enables direct use with multiplexed high-voltage sensor arrays. The specification is validated per TI SBOSA34E and applies across –40°C to +125°C.
Does TLV9354QPWRQ1 support single-supply operation?
Yes, TLV9354QPWRQ1 operates from a single supply of 4.5 V to 40 V, as well as dual supplies of ±2.25 V to ±20 V. Its rail-to-rail output stage delivers usable swing within 10 mV of either rail at no load, and its input common-mode range extends to (V–) – 0.2 V and (V+) – 2 V - making it suitable for grounded-sensor interfaces in 12 V and 24 V automotive systems.
How does TLV9354QPWRQ1 achieve EMI immunity without external filters?
TLV9354QPWRQ1 integrates on-die RF filtering on both input pins, providing measured EMIRR of 94 dB at 5 GHz. This is achieved through proprietary input-stage layout and passive filtering elements fabricated within the silicon die - verified per TI's standardized 10 MHz–6 GHz EMI test methodology. No external RC networks are required to meet CISPR 25 Class 5 radiated immunity targets.
Can TLV9354QPWRQ1 be used as a comparator?
Yes, TLV9354QPWRQ1 is explicitly designed for open-loop comparator operation. Its MUX-friendly inputs tolerate differential swings up to 40 V, and it features fast overload recovery (<600 ns) and no phase reversal. When used as a comparator, it maintains stability without external hysteresis in most automotive threshold-detection applications - confirmed in TI SBOSA34E Section 6.4.
What is the thermal performance of TLV9354QPWRQ1 in TSSOP package?
In its 14-pin TSSOP (PW) package, TLV9354QPWRQ1 has a junction-to-ambient thermal resistance (RθJA) of 118 °C/W and junction-to-board (RθJB) of 60.9 °C/W. At maximum 3.4 mA quiescent current and 40 V supply, power dissipation remains below 140 mW - enabling reliable operation at +125°C ambient without forced airflow or heatsinking in standard automotive PCB layouts.
