Product details
Overview
TLV9051QDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified single-channel CMOS operational amplifier designed for automotive signal conditioning in high-dynamic-range, low-voltage systems. It delivers 5MHz unity-gain bandwidth, 15V/µs slew rate, ±0.33mV input offset voltage, rail-to-rail input/output swing, and 330µA quiescent current - enabling precision sensing and motor control in HEV/EV battery-management and traction inverter subsystems.
For engineers reviewing the TLV9051QDBVRQ1 datasheet, TLV9051QDBVRQ1 pinout, TLV9051QDBVRQ1 application, or TLV9051QDBVRQ1 equivalent, key selection criteria include its 1.8V–6V supply range, –40°C to +125°C operation, EMI-hardened architecture, capacitive-load drive up to 150pF, and unity-gain stability without external compensation.
Technical Context
The TLV9051QDBVRQ1 employs a complementary differential input stage (N- and P-channel pairs) enabling true rail-to-rail common-mode input range extending 100mV beyond both supply rails across 1.8V–6V operation. Its class AB output stage achieves 16mV rail-to-rail swing into 10kΩ loads and maintains stability with ≥150pF capacitive loads due to low open-loop output impedance (250Ω at 5MHz).
It integrates on-die RFI/EMI filtering validated per AEC-Q100, with EMIRR IN+ of 92.5dB at 5GHz and 71.8dB at 1.8GHz. The device avoids phase reversal under overdrive and exhibits no input bias current shift up to ±0.5V differential input - critical for precision current-sense and sensor front-end applications in safety-critical automotive systems.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-gain bandwidth | 5MHz - supports stable closed-loop operation at G = +1 with fast settling for motor-control feedback loops. |
| Slew rate | 15V/µs - enables accurate amplification of fast transients in battery-cell voltage monitoring and gate-driver biasing. |
| Input offset voltage | ±0.33mV (typ) - ensures sub-mV error in low-side current sensing with 50mΩ shunts at 10A full scale. |
| Quiescent current | 330µA - allows continuous operation in always-on BMS domains without compromising battery standby life. |
| Rail-to-rail I/O | Input extends (V−) − 0.1V to (V+) + 0.1V; output swings within 16mV of rails at 10kΩ - maximizes dynamic range in 3.3V or 5V automotive domains. |
| EMI rejection | 92.5dB at 5GHz - suppresses interference from 5GHz Wi-Fi/DSRC co-location in infotainment-integrated power modules. |
| Capacitive load drive | Stable with ≥150pF - accommodates long PCB traces or ESD protection networks without oscillation. |
Pinout & Package
TLV9051QDBVRQ1 is packaged in a 5-pin SOT-23 (DBV) footprint measuring 2.90mm × 2.80mm, optimized for space-constrained automotive ECUs and power modules.
| Pin | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT | Amplifier output - drives resistive or capacitive loads directly; capable of sourcing/sinking ±50mA short-circuit current. |
| 2 | V− | Negative supply or ground reference - establishes low-side bias point; accepts single-supply operation down to 1.8V total supply. |
| 3 | IN+ | Noninverting input - high-impedance node (2pA bias current) for precision sensor interfaces or reference buffering. |
| 4 | IN− | Inverting input - used for transimpedance, difference-amplifier, or active-filter configurations; immune to phase reversal. |
| 5 | V+ | Positive supply - supports up to 6V operation; internal regulation ensures consistent performance across battery voltage fluctuations. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 qualification | Validated for –40°C to +125°C ambient operation - meets thermal requirements for under-hood and powertrain-mounted electronics. |
| Internal RFI/EMI filter | Reduces susceptibility to 400MHz–6GHz emissions without external LC filters - simplifies layout in ECU modules near RF transceivers. |
| Unity-gain stable | Operates reliably at G = +1 without external compensation - eliminates design risk in voltage-follower configurations for ADC input buffering. |
| Low broadband noise | 15nV/√Hz at 10kHz - preserves SNR in high-gain analog front-ends for resolver-to-digital converters and torque sensor interfaces. |
| No phase reversal | Remains linear during input overdrive - prevents latch-up or erroneous control signals in fault-detection circuits during transient events. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV931QDBVRQ1 | Lower slew rate (1.5V/µs), higher IQ (120µA), same AEC-Q100 Grade 1 rating and SOT-23 package. | Optimized for low-frequency sensor buffering (e.g., cabin temperature) where bandwidth <1MHz suffices. | Select when cost sensitivity outweighs need for fast transient response - LMV931QDBVRQ1 offers 30% lower unit price but cannot support >100kHz current-loop bandwidths. |
| TSV911QDBVRQ1 | Higher offset (±1.5mV), lower EMI rejection (78dB at 5GHz), identical 5MHz GBW and 15V/µs slew rate. | Targeted at non-safety-critical body electronics where ASIL-B compliance is not required. | Choose for non-ASIL applications needing same speed but lower qualification overhead - TSV911QDBVRQ1 lacks AEC-Q100 stress validation for powertrain use. |
Compared with LMV931QDBVRQ1 and TSV911QDBVRQ1, TLV9051QDBVRQ1 uniquely combines AEC-Q100 Grade 1 qualification, 15V/µs slew rate, and 92.5dB 5GHz EMIRR - making it the only option for ASIL-B-compliant, high-bandwidth, EMI-resilient signal conditioning in traction inverters and OBCs.

FAQ
What is the maximum capacitive load the TLV9051QDBVRQ1 can drive while maintaining stability?
The TLV9051QDBVRQ1 is characterized for stable operation with ≥150pF capacitive loads, as confirmed in the datasheet's Phase Margin vs Capacitive Load plot (Figure 5-17). Its low open-loop output impedance (250Ω at 5MHz) and unity-gain stability eliminate need for isolation resistors in typical PCB layouts - enabling direct connection to ADC input capacitors or long sensor traces without peaking or oscillation.
Does TLV9051QDBVRQ1 support true rail-to-rail input operation at 1.8V supply?
Yes, TLV9051QDBVRQ1 maintains rail-to-rail input capability across its full 1.8V–6V supply range, with common-mode voltage specified from (V−) − 0.1V to (V+) + 0.1V. At 1.8V, this provides a usable input range of –0.1V to +1.9V - essential for interfacing with low-voltage sensors and microcontrollers in modern 12V automotive architectures.
How does the EMI rejection performance of TLV9051QDBVRQ1 compare to standard op amps in automotive environments?
TLV9051QDBVRQ1 delivers 92.5dB EMIRR IN+ at 5GHz - exceeding typical automotive op amps by ≥20dB. This is achieved via integrated on-die RFI/EMI filtering, validated per AEC-Q100. In practice, this suppresses interference from 5GHz Wi-Fi, DSRC, and cellular bands without external ferrite beads or shielded enclosures, reducing layout complexity in densely packed ECUs.
Can TLV9051QDBVRQ1 be used in single-supply configurations with ground-referenced inputs?
Yes, TLV9051QDBVRQ1 is explicitly designed for single-supply operation: V− pin serves as ground reference, and the input common-mode range extends 100mV below V−. This allows direct connection of ground-referenced sensors (e.g., thermistors, potentiometers) without level-shifting circuitry - simplifying designs for HVAC and lighting control modules.
What is the guaranteed input offset voltage drift over temperature for TLV9051QDBVRQ1?
TLV9051QDBVRQ1 has a maximum input offset voltage drift of ±0.5µV/°C over –40°C to +125°C, as specified in Section 5.7 of the datasheet. This low drift ensures minimal gain error accumulation in precision current-sense amplifiers operating across full automotive temperature ranges - critical for accurate state-of-charge estimation in BMS applications.
