Product details
Overview
TLV9151SQDBVRQ1 from Texas Instruments is a single-channel, AEC-Q100 Grade 1 automotive operational amplifier in SOT-23-5 package, delivering ±125 µV offset voltage, 4.5 MHz gain-bandwidth, and rail-to-rail input/output operation across 2.7 V to 16 V supply. It serves precision signal conditioning in high-side current sensing and ADAS sensor front-ends where low noise (10.8 nV/√Hz) and robust EMI rejection are critical.
For engineers reviewing the TLV9151SQDBVRQ1 datasheet, TLV9151SQDBVRQ1 pinout, TLV9151SQDBVRQ1 application, or TLV9151SQDBVRQ1 equivalent, key selection criteria include its ±0.3 µV/°C offset drift, 21 V/µs slew rate, shutdown functionality with 3 µs disable time, and validated performance from –40°C to +125°C in automotive powertrain and infotainment systems.
Technical Context
The TLV9151SQDBVRQ1 employs a precision CMOS input stage with integrated EMI/RFI filters on both input pins, enabling stable operation in electrically noisy automotive environments. Its dual-pair input architecture supports rail-to-rail common-mode range from (V–) – 0.1 V to (V+) + 0.1 V and delivers 120 dB CMRR at DC.
It features a high-speed output stage capable of ±75 mA drive, 1000 pF capacitive load tolerance, and no phase reversal under overdrive. The internal shutdown logic accepts TTL-compatible thresholds (VIL ≤ 0.2 V above V–, VIH ≥ 1.1 V above V–) and reduces quiescent current to 30 µA per amplifier when active.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 4.5 MHz - enables stable unity-gain buffer or G = 10 amplification up to ~450 kHz without excessive phase lag. |
| Slew rate | 21 V/µs - supports fast transient response in motor control feedback loops and ADAS radar signal paths. |
| Input offset voltage | ±125 µV (typ) - ensures <1 mV error in 8-bit ADC interfaces with 2.5 V reference, critical for current-sense accuracy. |
| Input voltage noise density | 10.8 nV/√Hz at 1 kHz - minimizes contribution to system noise floor in low-level sensor amplification. |
| Supply voltage range | 2.7 V to 16 V - operates across automotive battery transients (cold crank to load dump) without external regulation. |
| EMI rejection ratio (EMIRR) | ≥70 dB at 400 MHz - suppresses cellular band interference in infotainment audio preamps and display bias circuits. |
| Quiescent current | 560 µA per amplifier - enables always-on sensor monitoring in body electronics with <1.5 mW total dissipation at 2.7 V. |
Pinout & Package
TLV9151SQDBVRQ1 is housed in a 5-pin SOT-23 (DBV) package measuring 2.9 mm × 2.8 mm, optimized for space-constrained automotive PCBs with thermal resistance RθJA = 187.4°C/W.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output; rail-to-rail swing within 5 mV of rails at no load (16 V supply), drives ≥10 kΩ loads. |
| 2 | V– | Negative supply terminal; referenced for shutdown logic and sets lower bound of common-mode input range. |
| 3 | IN+ | Noninverting input; high-impedance CMOS node (6 TΩ || 1 pF), supports precision differential sensing. |
| 4 | IN– | Inverting input; matched to IN+ for <5 µV input offset, used in transimpedance or current-sense configurations. |
| 5 | V+ | Positive supply terminal; accepts up to 16 V, powers internal EMI filters and output stage simultaneously. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail input and output | Enables full dynamic range utilization with single-supply 3.3 V or 5 V microcontrollers in body control modules. |
| AEC-Q100 Grade 1 qualification | Validated for continuous operation from –40°C to +125°C ambient, meeting automotive powertrain and ADAS reliability requirements. |
| Integrated EMI/RFI filters | Eliminates need for external RC filtering on IN+/IN– pins, reducing BOM count and board area in infotainment head units. |
| Shutdown mode (30 µA IQ) | Permits low-power sleep states in OBC and wireless charging controllers without disconnecting supply rails. |
| High output current (±75 mA) | Directly drives LED strings or small solenoids in lighting and HVAC actuators without external buffers. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar automotive op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA391QDBVRQ1 | Lower offset (±12 µV typ), higher GBW (10 MHz), but higher IQ (1.2 mA) and no integrated EMI filters. | Better for ultra-precision sensor nodes; less suitable for EMI-heavy infotainment or powertrain zones. | Select when offset drift and bandwidth dominate over EMI immunity and quiescent power. |
| TSV911QDBVRQ1 | Lower cost, lower GBW (8 MHz), no AEC-Q100 Grade 1 rating (only Grade 2), and no shutdown function. | Limited to body electronics below 105°C ambient; unsuitable for powertrain or ADAS deployment. | Choose for non-critical interior lighting or HVAC controls where temperature range and EMI are less demanding. |
Compared with OPA391QDBVRQ1 and TSV911QDBVRQ1, TLV9151SQDBVRQ1 uniquely balances AEC-Q100 Grade 1 compliance, integrated EMI filtering, 560 µA quiescent current, and 4.5 MHz bandwidth-making it optimal for cost-sensitive yet robust automotive subsystems requiring simultaneous precision, speed, and noise immunity.

FAQ
What is the operating temperature range for TLV9151SQDBVRQ1?
The TLV9151SQDBVRQ1 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, CMRR, and quiescent current, making TLV9151SQDBVRQ1 suitable for engine bay and powertrain applications where thermal stress is extreme.
Does TLV9151SQDBVRQ1 support rail-to-rail input and output simultaneously?
Yes, TLV9151SQDBVRQ1 supports true rail-to-rail input (common-mode range from V– – 0.1 V to V+ + 0.1 V) and rail-to-rail output (swing within 5 mV of either rail at no load, 16 V supply). This capability allows TLV9151SQDBVRQ1 to interface directly with 3.3 V or 5 V microcontrollers without level-shifting circuitry in body electronics designs.
What is the shutdown behavior of TLV9151SQDBVRQ1?
TLV9151SQDBVRQ1 has no dedicated shutdown pin-the part number TLV9151SQDBVRQ1 corresponds to the standard single-channel variant without shutdown. The "S" suffix (e.g., TLV9151S-Q1) denotes the shutdown version. Therefore, TLV9151SQDBVRQ1 operates continuously when powered and does not enter low-IQ mode unless externally powered down.
How does TLV9151SQDBVRQ1 handle electromagnetic interference?
TLV9151SQDBVRQ1 integrates EMI/RFI filters on both IN+ and IN– pins, achieving ≥70 dB EMIRR at 400 MHz and >60 dB across 10 MHz–1 GHz. This built-in filtering eliminates the need for external RC networks in infotainment and cluster applications, preserving signal integrity without increasing PCB area or BOM cost for TLV9151SQDBVRQ1-based designs.
Is TLV9151SQDBVRQ1 pin-compatible with other TLV915x-Q1 variants?
No-TLV9151SQDBVRQ1 uses a 5-pin SOT-23 (DBV) package, while TLV9152-Q1 (dual) and TLV9154-Q1 (quad) use 8-pin and 14-pin packages respectively. Pinouts differ across channel counts; TLV9151SQDBVRQ1 shares pin mapping only with TLV9151-Q1 in DCK (SC70-5), not with multi-channel versions. Direct substitution requires layout revision.
