Product details
Overview
TLV9104QPWRQ1 from Texas Instruments is a quad-channel, AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, 1.1MHz gain-bandwidth, ±300µV max input offset voltage, 120µA per amplifier quiescent current, and 4.5V/µs slew rate - deployed in HEV/EV battery management systems and motor control signal conditioning.
For engineers reviewing the TLV9104QPWRQ1 datasheet, TLV9104QPWRQ1 pinout, TLV9104QPWRQ1 application, or TLV9104QPWRQ1 equivalent, key selection criteria include its 16V supply range (±1.35V to ±8V), robust 77dB EMIRR at 1.8GHz, ±80mA output drive, thermal shutdown protection, and guaranteed operation from –40°C to +125°C.
Technical Context
The TLV9104QPWRQ1 integrates phase-reversal protection to prevent output inversion when inputs exceed rails, and features internal EMI filtering optimized for automotive environments - delivering 77.8dB EMIRR at 1.8GHz and 78.0dB at 2.4GHz. Its rail-to-rail input stage supports common-mode voltages from (V–) – 0.2V to (V+) + 0.2V across the full temperature range.
Thermal protection activates at 140°C junction temperature, forcing output into high-impedance state to prevent damage. The device maintains 110dB CMRR and 135dB open-loop gain at 25°C, with low 0.6µV/°C offset drift and 28nV/√Hz input noise at 10kHz - enabling precision sensor interfacing in noisy powertrain domains.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Supply Voltage Range | 2.7V to 16V (±1.35V to ±8V) - supports 12V/48V automotive architectures without level-shifting |
| Gain-Bandwidth Product | 1.1MHz - enables stable closed-loop gain up to 100 at DC–11kHz for BMS cell voltage monitoring |
| Input Offset Voltage | ±300µV (max) - ensures ≤0.003% error in 10V-range differential sensing circuits |
| Quiescent Current | 120µA per amplifier - allows four channels to operate under 500µA total, critical for always-on modules |
| Slew Rate | 4.5V/µs - supports <5µs settling to 0.1% for 10V step signals in motor current feedback loops |
| EMI Rejection Ratio | 77dB at 1.8GHz - suppresses GSM/LTE interference in infotainment-adjacent power electronics |
| Output Drive | ±80mA - directly drives 100Ω loads or RC filters without external buffers in HVAC compressor control |
Pinout & Package
TLV9104QPWRQ1 is packaged in a 14-pin TSSOP (PW) with 5mm × 6.4mm footprint, rated for –40°C to +125°C operation and qualified to AEC-Q100 Grade 1.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT1, OUT2, OUT3, OUT4 | Amplifier output (x4) | Capable of ±80mA sourcing/sinking; rail-to-rail swing within 3mV of supply rails at no load |
| IN1+, IN1−, IN2+, IN2−, IN3+, IN3−, IN4+, IN4− | Differential input pairs (x4) | Rail-to-rail common-mode range (V– – 0.2V to V+ + 0.2V); ±10pA bias current minimizes resistor-induced errors |
| V+ | Positive supply | Highest potential rail; accepts up to 16V; powers all four amplifiers and internal bias circuitry |
| V– | Negative supply | Lowest potential rail; supports single-supply (2.7V–16V) or dual-supply (±1.35V to ±8V) configurations |
| NC | No-connect | Pin 11 is unconnected; must remain floating - not tied to V– or ground per TI design guidance |
Key Features
| Feature | Design Value |
|---|---|
| Phase-reversal protection | Prevents output inversion when inputs exceed supply rails - eliminates latch-up risk in overvoltage transients on BMS sense lines |
| Integrated EMI filtering | Delivers 77.8dB rejection at 1.8GHz - reduces need for external ferrite beads or shielding in compact EV inverters |
| Thermal shutdown | Activates at 140°C junction temperature - forces output high-Z to protect against sustained overload in 48V DC/DC converters |
| Rail-to-rail I/O | Enables full dynamic range utilization with 3mV headroom at 16V supply - maximizes ADC resolution in zone controller analog front-ends |
| Low offset drift | ±0.6µV/°C - limits total offset shift to <100µV over –40°C to +125°C, critical for precision current shunt amplification |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV934QDRQ1 | Lower bandwidth (1.5MHz), higher IQ (160µA/ch), no integrated EMI filtering, 70dB EMIRR at 1.8GHz | Lacks phase-reversal protection and thermal shutdown; less suited for high-noise inverter proximity | Acceptable where EMI immunity and fault resilience are secondary to cost in body electronics |
| TSV914IQDT | Higher offset (±1.5mV), lower PSRR (90dB), no AEC-Q100 qualification, 125°C max operating temp | Not automotive-qualified; unsuitable for powertrain or safety-critical zones | Only for non-automotive industrial use cases requiring same pinout but lacking automotive compliance |
Compared with LMV934QDRQ1 and TSV914IQDT, TLV9104QPWRQ1 delivers superior EMI resilience (77dB vs ≤70dB), guaranteed thermal protection, and tighter DC precision - making it the only qualified option for HEV/EV power conversion and motor control signal chains where reliability and noise immunity are non-negotiable.

FAQ
What is the maximum supply voltage rating for TLV9104QPWRQ1?
The TLV9104QPWRQ1 has an absolute maximum supply voltage of 20V (V+ to V–), but its recommended operating range is 2.7V to 16V. Operating beyond 16V risks exceeding safe junction temperature and invalidating AEC-Q100 qualification - TI specifies 16V as the upper limit for guaranteed parametric performance and reliability in automotive applications.
Does TLV9104QPWRQ1 support single-supply operation?
Yes, TLV9104QPWRQ1 supports true single-supply operation from 2.7V to 16V with rail-to-rail input and output stages. Its common-mode input range extends from (V–) – 0.2V to (V+) + 0.2V, and output swings within 3mV of both rails at no load - enabling direct interfacing with microcontrollers and ADCs in 3.3V or 5V domains without level-shifting circuitry.
Is TLV9104QPWRQ1 pin-compatible with other devices in the TLV910x-Q1 family?
No - TLV9104QPWRQ1 (quad, 14-pin TSSOP) is not pin-compatible with TLV9101-Q1 (single, 5-pin SOT-23/SC70) or TLV9102-Q1 (dual, 8-pin SOIC/VSSOP). Pin counts, layouts, and channel assignments differ across the family; PCB redesign is required when substituting between channel variants, even within the same package type.
What thermal protection behavior does TLV9104QPWRQ1 exhibit under overload?
When junction temperature exceeds 140°C, TLV9104QPWRQ1 disables output drive and places all four amplifier outputs in high-impedance state - preventing thermal runaway. Once temperature falls below 135°C (typical hysteresis), normal operation resumes automatically. This behavior is verified per AEC-Q100 stress testing and documented in TI's SBOSAJ3 datasheet Section 6.3.3.
How does TLV9104QPWRQ1 handle input overvoltage beyond the supply rails?
TLV9104QPWRQ1 incorporates phase-reversal protection that prevents output inversion when inputs exceed (V–) – 0.2V or (V+) + 0.2V. Instead of reversing polarity, the output clamps to the appropriate rail - preserving signal integrity during transients such as load dump or jump-start events in automotive 12V systems.
