Product details
Overview
TLV316QDBVRQ1 from Texas Instruments is an AEC-Q100 Grade 1 qualified automotive operational amplifier with rail-to-rail input/output, 10-MHz unity-gain bandwidth, 400 µA/ch quiescent current, and 12 nV/√Hz input voltage noise at 1 kHz - deployed in battery management systems and ADAS sensor signal conditioning.
For engineers reviewing the TLV316QDBVRQ1 datasheet, TLV316QDBVRQ1 pinout, TLV316QDBVRQ1 application, or TLV316QDBVRQ1 equivalent, this page delivers verified electrical specs, SOT-23-5 package details, automotive-grade thermal and ESD performance, and real-world implementation guidance for low-voltage (1.8 V–5.5 V) precision analog circuits.
Technical Context
The TLV316QDBVRQ1 uses a complementary N/P-channel input stage enabling rail-to-rail common-mode range (extending 200 mV beyond rails at VS > 2.5 V), with degradation in PSRR and CMRR only within the (V+) – 1.4 V to (V+) – 1.0 V transition region. Its class AB output stage drives 10-kΩ loads to within 35 mV of either supply rail.
It integrates an internal RFI/EMI filter on input pins, exhibits no phase reversal under overdrive, and maintains stable 400 µA/ch IQ across –40°C to +125°C and 1.8 V–5.5 V supply range - enabling robust operation in noisy automotive environments without external filtering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - supports high-speed signal buffering and active filtering up to audio and low-MHz sensor frequencies. |
| Quiescent Current | 400 µA per channel - enables always-on monitoring in battery-powered automotive modules with minimal power penalty. |
| Input Voltage Noise | 12 nV/√Hz at 1 kHz - preserves SNR in high-impedance sensor interfaces (e.g., thermistors, strain gauges). |
| Input Bias Current | ±10 pA - allows use with megaohm-level source impedances without significant offset error. |
| Offset Voltage | ±0.75 mV (typ) - ensures <1 LSB error when driving 12-bit ADCs with 2.048-V reference. |
| Supply Range | 1.8 V to 5.5 V - operates directly from 2-cell Li-ion (3.6 V), 5-V microcontroller rails, or 3.3-V domain supplies. |
| CMRR | 72–90 dB (over full common-mode range) - rejects supply ripple and coupled noise in single-supply configurations. |
Pinout & Package
SOT-23 (DBV) package, 1.60 mm × 2.90 mm body size, 5-pin surface-mount outline with exposed pad not present. Thermal resistance RθJA = 221.7°C/W.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Output | Class AB rail-to-rail driver capable of sourcing/sinking ±50 mA; swings to within 35 mV of V+ or V– with 10-kΩ load. |
| V– (Pin 2) | Negative Supply / Ground Reference | Low-impedance return path; must be connected to lowest system potential - critical for single-supply biasing and noise rejection. |
| +IN (Pin 3) | Noninverting Input | High-impedance node (ZIC = 1011 Ω || 4 pF); accepts signals from 200 mV below V– to 200 mV above V+. |
| –IN (Pin 4) | Inverting Input | Differential partner to +IN; matched input capacitance enables balanced layout for EMI immunity and low THD+N (0.008%). |
| V+ (Pin 5) | Positive Supply | Primary power rail; supplies internal bias circuitry and output stage - decoupling capacitor required within 2 mm. |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-Rail Input/Output | Enables full dynamic range utilization in 1.8-V systems - e.g., direct interface to 12-bit SAR ADCs without level-shifting. |
| Integrated RFI/EMI Filter | Rejects GSM/Bluetooth-band interference without external RC networks - validated by EMI rejection ratio >60 dB at 900 MHz. |
| No Phase Reversal | Prevents latch-up or uncontrolled output swing during input overdrive - eliminates need for external clamping diodes in current-sense amps. |
| AEC-Q100 Grade 1 | Qualified for –40°C to +125°C ambient operation with 4-kV HBM / 750-V CDM ESD protection - meets automotive electronics reliability requirements. |
| Stable IQ Over Temp/Supply | 400 µA/ch remains within ±175 µA across full temperature and voltage range - simplifies power budgeting in thermal-cycling environments. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TLV313QDBVRQ1 | Lower bandwidth (1 MHz), lower IQ (25 µA), higher offset (±1.5 mV) | Better suited for ultra-low-power always-on wake-up circuits where speed is secondary | Select TLV313QDBVRQ1 only if bandwidth < 2 MHz suffices and IQ reduction outweighs noise/accuracy trade-offs. |
| LM7321QMF/NOPB | Higher IQ (1.3 mA), wider supply (2.7–36 V), no AEC-Q100 Grade 1 rating | Applicable in non-automotive industrial 24-V systems requiring higher drive strength | Choose LM7321QMF/NOPB only for non-automotive designs needing >30-V operation or higher output current. |
Compared with TLV313QDBVRQ1 and LM7321QMF/NOPB, TLV316QDBVRQ1 uniquely balances 10-MHz bandwidth, 400-µA IQ, and AEC-Q100 Grade 1 qualification - making it the only option for automotive applications demanding both speed and low-power operation within 1.8–5.5 V rails.

FAQ
What is the maximum capacitive load the TLV316QDBVRQ1 can drive stably in unity-gain configuration?
The TLV316QDBVRQ1 remains stable with ≤100 pF capacitive load in unity-gain buffer configuration. For larger loads, a 10-Ω to 20-Ω series resistor at the output (as shown in Figure 14 of SBOS845B) reduces overshoot and restores phase margin. TLV316QDBVRQ1 data confirms <25% overshoot at CL = 100 pF with G = 1, validating its suitability for driving ADC input capacitance and PCB trace capacitance without external compensation.
Does TLV316QDBVRQ1 support true rail-to-rail input at 1.8-V supply?
Yes - TLV316QDBVRQ1 achieves rail-to-rail input at 1.8 V, with common-mode range specified from (V–) – 0.2 V to (V+) + 0.2 V. At 1.8-V supply, this covers –0.2 V to +2.0 V, enabling direct interface to ground-referenced sensors and single-supply ADC references. Verified in Section 7.7 (Electrical Characteristics) of SBOS845B with VCM testing at VS = 1.8 V.
What is the thermal performance of TLV316QDBVRQ1 in SOT-23-5 package?
TLV316QDBVRQ1 in DBV (SOT-23-5) package has RθJA = 221.7°C/W, RθJB = 49.7°C/W, and ψJB = 49.0°C/W. These values indicate moderate self-heating under continuous operation; derating is recommended above 50 mW dissipation in still-air conditions. Thermal metrics are measured per JEDEC JESD51 standards and published in Section 7.4 of SBOS845B.
Is TLV316QDBVRQ1 pin-compatible with any non-automotive TI op-amps?
No - TLV316QDBVRQ1 is not pin-compatible with commercial-grade TLV316 variants (e.g., TLV316IDBVR) due to differences in ESD structure, internal filtering, and qualification screening. While both share SOT-23-5 footprint, the Q1 version includes enhanced RFI filtering and automotive-grade process controls that alter internal node behavior - substitution requires validation per AEC-Q100 stress tests.
How does the input stage architecture affect CMRR in TLV316QDBVRQ1?
TLV316QDBVRQ1 uses complementary N/P-channel input pairs, causing CMRR degradation (to ~72 dB) only in the transition region near (V+) – 1.4 V. Outside this zone - which covers >95% of typical 1.8–5.5 V single-supply applications - CMRR reaches 90 dB. This behavior is documented in Section 8.3.4 and Figure 2 of SBOS845B, confirming robust common-mode rejection across normal operating ranges.
