Product details
Overview
TLV9154QDYYRQ1 from Texas Instruments is a quad-channel AEC-Q100 Grade 1 automotive operational amplifier with rail-to-rail input/output, ±125µV offset voltage, 4.5MHz gain-bandwidth, and 21V/µs slew rate. It delivers low-noise (10.8nV/√Hz at 1kHz), high CMRR (120dB), and robust EMI rejection for precision signal conditioning in HEV/EV motor control and ADAS current sensing.
For engineers reviewing the TLV9154QDYYRQ1 datasheet, TLV9154QDYYRQ1 pinout, TLV9154QDYYRQ1 application, or TLV9154QDYYRQ1 equivalent, key selection criteria include its quad-channel SOT-23-14 package, ±1.35V to ±8V dual-supply operation, 560µA per amplifier quiescent current, and AEC-Q100 qualification for –40°C to +125°C ambient operation.
Technical Context
The TLV9154QDYYRQ1 implements a precision bipolar-input op amp architecture optimized for DC accuracy and wideband AC performance. Its input stage supports rail-to-rail common-mode range (V– –0.1V to V+ +0.1V) and features integrated EMI/RFI filters on all input pins, delivering measured EMIRR >70dB across 10MHz–1GHz.
Each of the four independent amplifiers provides 75mA output drive capability, 0.3µV/°C offset drift, and stable unity-gain operation with up to 1000pF capacitive load-enabling direct interface with sensors, ADC drivers, and active filters in safety-critical automotive subsystems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Channels | Quad - enables compact multi-sensor signal chains without board-level duplication |
| Gain-bandwidth product | 4.5MHz - supports closed-loop bandwidths up to ~400kHz at G=10 for fast current loop feedback |
| Slew rate | 21V/µs - ensures <2.5µs settling to 0.01% for 10V step, critical for motor phase current reconstruction |
| Input offset voltage | ±125µV (typ) - reduces baseline error in shunt-based current sensing below 0.1% at 100mΩ sense resistor |
| Quiescent current | 560µA per amplifier - enables low-power always-on monitoring in body electronics with <2.25mA total for full quad |
| Supply voltage range | 2.7V to 16V single or ±1.35V to ±8V dual - interoperates with 3.3V, 5V, and 12V automotive domains |
| EMI rejection | EMIRR >70dB at 400MHz - suppresses cellular band interference in infotainment-adjacent sensor nodes |
Pinout & Package
TLV9154QDYYRQ1 uses a 14-pin SOT-23 package (DYY), measuring 4.2mm × 3.26mm, optimized for space-constrained automotive modules. The package supports reflow soldering and meets IPC/JEDEC J-STD-020 moisture sensitivity level 3.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 7, 8, 14 | OUT1–OUT4 | Amplifier outputs - each capable of ±75mA drive and rail-to-rail swing within 10mV of rails at light load |
| 2, 6, 9, 13 | IN1––IN4– | Inverting inputs - high-impedance (6TΩ || 1pF) with EMI filtering; tolerate ±0.5V beyond supply rails when current-limited |
| 3, 5, 10, 12 | IN1+–IN4+ | Noninverting inputs - identical EMI-filtered structure; support common-mode range from V– –0.1V to V+ +0.1V |
| 4 | V+ | Positive supply - connects to highest potential rail; decoupling capacitor required within 5mm |
| 11 | V– | Negative supply - connects to lowest potential rail; serves as reference for all four amplifiers' bias networks |

IC Role / Device Role / Timing Role: Dedicated amplifier per sensor channel with programmable gain via external resistors; shutdown pins enable dynamic power gating. Use Value: 560µA per amplifier and individual SHDN control reduce idle power to <100µA per active channel, extending sleep-mode battery life. |
Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TSV914IQDTQ1 | Lower 1.3MHz GBW, higher 1.1mV max offset, no integrated EMI filters | Better suited for cost-sensitive non-safety body electronics where EMI immunity is secondary | Choose when bandwidth and EMI rejection are not critical, and lower unit cost is prioritized |
| OPA4991QDGQRQ1 | Higher 4.5MHz GBW but 1.2mA per amplifier IQ; no AEC-Q100 Grade 1 rating | Targeted at industrial-grade systems requiring same speed but lacking automotive qualification | Use only in non-automotive contexts where AEC-Q100 compliance is unnecessary |
Compared with TSV914IQDTQ1 and OPA4991QDGQRQ1, TLV9154QDYYRQ1 uniquely combines AEC-Q100 Grade 1 qualification, 4.5MHz bandwidth, sub-130µV offset, and integrated EMI filtering in a 4.2mm × 3.26mm SOT-23 package-making it the only option qualified for safety-critical HEV/EV and ADAS signal chains requiring simultaneous precision, speed, and robustness.

FAQ
What is the operating temperature range for TLV9154QDYYRQ1?
The TLV9154QDYYRQ1 is qualified per AEC-Q100 Grade 1, supporting continuous operation from –40°C to +125°C ambient temperature. This range is validated across all electrical parameters including offset voltage drift (±0.3µV/°C), CMRR (≥99dB), and quiescent current (≤750µA per amplifier) under full temperature stress.
Does TLV9154QDYYRQ1 support single-supply operation?
Yes, TLV9154QDYYRQ1 supports true single-supply operation from 2.7V to 16V. Its rail-to-rail input stage accepts common-mode voltages from V– –0.1V to V+ +0.1V, and rail-to-rail output swings within 10mV of both rails at no load-enabling direct interfacing with 3.3V or 5V microcontrollers without level-shifting circuitry.
What is the maximum capacitive load TLV9154QDYYRQ1 can drive stably?
The TLV9154QDYYRQ1 is specified to drive up to 1000pF capacitive load while maintaining ≥60° phase margin and monotonic step response. For loads exceeding 1000pF, external isolation resistance (RISO ≥50Ω) is recommended to preserve stability, as verified in Figure 5-27 and 5-28 of the datasheet.
How does the EMI rejection feature of TLV9154QDYYRQ1 work?
TLV9154QDYYRQ1 integrates on-die R-C filters on all input pins, providing >70dB electromagnetic interference rejection ratio (EMIRR) at 400MHz. This eliminates susceptibility to cellular, Wi-Fi, and radar band noise without requiring external filtering components-critical for reliable operation in densely packed automotive ECUs near infotainment or telematics modules.
Is TLV9154QDYYRQ1 pin-compatible with other TLV915x-Q1 variants?
No, TLV9154QDYYRQ1 in the 14-pin SOT-23 (DYY) package is not pin-compatible with TLV9154-Q1 in SOIC-14 or TSSOP-14 packages due to differing pin assignments and thermal pad configurations. Pin mapping is unique to the DYY variant, as shown in Table 4-4 of the datasheet-board layout must be designed specifically for DYY mechanical and electrical interface.
