Product details
Overview
TLV365QDBVRQ1 from Texas Instruments is a single-channel, AEC-Q100 Grade 1 qualified automotive operational amplifier featuring zero-crossover distortion topology, 50MHz gain bandwidth, rail-to-rail input/output, and 115dB typical CMRR. It operates from 2.2V to 5.5V supply and delivers 27V/µs slew rate with 4.5nV/√Hz input voltage noise - optimized for precision low-side current sensing in HEV/EV power stages.
For engineers reviewing the TLV365QDBVRQ1 datasheet, TLV365QDBVRQ1 pinout, TLV365QDBVRQ1 application, or TLV365QDBVRQ1 equivalent, key selection criteria include its 0.2µs 0.01% settling time, ±20pA max input bias current, 12mV rail-to-rail output swing, and validated performance across –40°C to +125°C for automotive motor control and DC/DC converter feedback loops.
Technical Context
The TLV365QDBVRQ1 employs a proprietary CMOS zero-crossover input stage that eliminates offset discontinuity across the full common-mode range (–0.1V to VS + 0.1V), enabling linear operation beyond both supply rails. Its high-speed architecture supports stable unity-gain operation while maintaining 56° phase margin and driving capacitive loads up to 100pF with external isolation resistor compensation.
This device integrates ESD protection per AEC-Q100-002 (±2kV HBM) and features active filter compatibility via Butterworth and Sallen-Key topologies. It lacks power-down modes and operates exclusively in continuous-conduction mode with no internal shutdown logic or enable pin.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain Bandwidth | 50MHz - enables accurate 12-bit+ SAR ADC driving at ≥2 MSPS sampling rates without settling error. |
| Slew Rate | 27V/µs - supports fast transient response in motor phase-current feedback and OBC voltage regulation loops. |
| Input Bias Current | ±20pA max - preserves signal integrity when amplifying high-impedance sensor outputs (e.g., shunt-based current sense). |
| CMRR | 115dB typical - rejects common-mode noise in noisy automotive power domains (e.g., inverter gate drive circuits). |
| Rail-to-Rail Output Swing | Within 12mV of rails - maximizes dynamic range for 3.3V ADC interfaces without level-shifting circuitry. |
| Offset Drift | 2.6µV/°C max - ensures <100µV total drift over –40°C to +125°C, critical for temperature-stable current measurement. |
| Noise Density | 4.5nV/√Hz - maintains SNR >90dB in 10kHz bandwidth applications like HVAC compressor current monitoring. |
Pinout & Package
TLV365QDBVRQ1 is housed in a 5-pin SOT-23 (DBV) package with 0.95mm pitch, 2.9mm × 1.6mm footprint, and 1.1mm height - suitable for space-constrained automotive PCB layouts.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| VOUT | Output | Amplified signal node; drives ADC inputs or reference buffers with 12mV rail clearance and ±85mA short-circuit capability. |
| –IN | Negative Input | Inverting input; accepts signals from –0.1V to VS + 0.1V, enabling true differential sensing in low-side configurations. |
| +IN | Positive Input | Noninverting input; supports high-Z sensor interfacing with ≤20pA bias current and 5pF differential capacitance. |
| V− | Negative Supply | Ground or negative rail connection; must be decoupled with 0.1µF ceramic capacitor placed adjacent to pin 2. |
| V+ | Positive Supply | Primary power input (2.2V–5.5V); requires local 0.1µF bypass to minimize PSRR degradation above 10kHz. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA365QDBVRQ1 | Same 50MHz GBW and 25V/µs slew rate, but higher 5.5µV/°C max offset drift and no AEC-Q100 Grade 1 certification. | Limited to under-hood ambient temperatures ≤105°C; not qualified for direct placement near inverter modules. | Select when cost sensitivity outweighs extended temperature validation, and layout allows remote placement from heat sources. |
| TLV2365QDRQ1 | Dual-channel variant in SOIC-8 package; identical electrical specs per channel but 140°C/W RθJA vs 179°C/W for TLV365QDBVRQ1. | Higher thermal resistance limits power density in compact OBC PCBs; dual configuration increases board area usage. | Choose only when dual-channel functionality is required and thermal derating margins allow SOIC-8 placement in constrained zones. |

FAQ
What is the maximum operating temperature range for TLV365QDBVRQ1?
TLV365QDBVRQ1 is AEC-Q100 Grade 1 qualified and specified for continuous operation from –40°C to +125°C ambient temperature. This rating covers junction temperatures up to 150°C under recommended operating conditions, making TLV365QDBVRQ1 suitable for under-hood automotive applications including inverter gate driver feedback and onboard charger voltage regulation.
Does TLV365QDBVRQ1 support single-supply operation?
Yes, TLV365QDBVRQ1 supports true single-supply operation from 2.2V to 5.5V. Its rail-to-rail input extends 100mV beyond both supply rails, and its output swings within 12mV of each rail - enabling direct interface with 3.3V or 5V microcontrollers and ADCs without level-shifting circuitry. The device also functions with split supplies (e.g., ±2.5V).
How does TLV365QDBVRQ1 achieve zero-crossover distortion?
TLV365QDBVRQ1 uses a proprietary CMOS input stage architecture that eliminates the offset voltage discontinuity typically seen in complementary-input op amps at rail transitions. This zero-crossover topology ensures monotonic behavior across the full common-mode range (–0.1V to VS + 0.1V), preserving linearity in precision current sensing and active filter applications where input signals cross supply boundaries.
Can TLV365QDBVRQ1 drive capacitive loads without oscillation?
TLV365QDBVRQ1 can drive capacitive loads up to 100pF in unity-gain buffer configuration when paired with an external isolation resistor (RISO) at the output, as documented in Figure 7-5 of the datasheet. Without RISO, stability degrades beyond ~20pF due to phase margin reduction; the recommended RISO values range from 10Ω to 50Ω depending on load capacitance.
What is the input bias current specification for TLV365QDBVRQ1?
TLV365QDBVRQ1 has a maximum input bias current of ±20pA over the full operating temperature range (–40°C to +125°C). This ultra-low value minimizes voltage drop across high-impedance gain-setting networks and preserves accuracy when amplifying signals from high-output-impedance sensors - a critical requirement in shunt-based current sensing used in TLV365QDBVRQ1 automotive applications.
