Product details
Overview
OPA316QDBVRQ1 from Texas Instruments is a single-channel, rail-to-rail input/output, automotive-grade CMOS operational amplifier optimized for low-voltage operation (1.8 V to 5.5 V). It delivers 10-MHz unity-gain bandwidth, 400 µA quiescent current per channel, 11 nV/√Hz input voltage noise at 1 kHz, ±0.5 mV offset voltage, and ±5 pA input bias current - enabling precision signal conditioning in battery-powered ADAS sensors and current-sensing circuits.
For engineers reviewing the OPA316QDBVRQ1 datasheet, OPA316QDBVRQ1 pinout, OPA316QDBVRQ1 application, or OPA316QDBVRQ1 equivalent, key selection criteria include its AEC-Q100 Grade 1 qualification (–40°C to +125°C), internal RFI-EMI filtering, unity-gain stability, and rail-to-rail swing capability under sub-2-V supply conditions.
Technical Context
The OPA316QDBVRQ1 employs a CMOS input stage with ultra-low input bias current (±5 pA typical) and integrated EMI/RFI rejection filters, making it suitable for high-impedance sensor interfaces and noisy automotive environments. Its open-loop gain exceeds 100 dB at 5.5 V supply and remains ≥94 dB down to 1.8 V, supporting stable closed-loop performance across the full operating voltage range.
Designed for unity-gain stability with no external compensation required, the device exhibits 60° phase margin and 6 V/µs slew rate. It avoids phase reversal during overdrive and supports rail-to-rail output swing within 15 mV of each rail (at 1.8 V, RL = 10 kΩ, –40°C to +125°C), ensuring accurate signal fidelity in single-supply configurations.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 10 MHz - enables stable amplification of signals up to 10 MHz without external compensation. |
| Quiescent Current | 400 µA/ch - allows continuous operation in always-on automotive modules powered by 12-V battery rails via LDOs. |
| Input Voltage Noise | 11 nV/√Hz at 1 kHz - preserves SNR in low-level sensor front-ends such as thermopiles or bridge-based current shunts. |
| Input Bias Current | ±5 pA - minimizes voltage error in megaohm-source applications like photodiode transimpedance amplifiers. |
| Offset Voltage | ±0.5 mV (typical) - ensures ≤0.5% gain error in 1-V full-scale current sensing with 100-mΩ shunt. |
| Supply Range | 1.8 V to 5.5 V - supports direct interface with 1.8-V microcontrollers and 3.3-V/5-V analog subsystems. |
| CMRR | 70–90 dB - rejects common-mode interference from shared ground paths in body electronics modules. |
Pinout & Package
SOT-23 (DBV) package, 5-pin, body size 1.60 mm × 2.90 mm, surface-mountable with standard reflow profile.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Output | Amplified differential signal output; rail-to-rail swing supports full dynamic range utilization in single-supply systems. |
| V– (Pin 2) | Negative Supply / Ground | Reference node for single-supply operation; connects directly to system ground or negative rail in dual-supply configurations. |
| +IN (Pin 3) | Noninverting Input | High-impedance CMOS input accepting signals up to V– – 0.2 V and V+ + 0.2 V (at VS ≥ 2.5 V). |
| –IN (Pin 4) | Inverting Input | Differential input node; matched to +IN for precision gain-setting with feedback resistors. |
| V+ (Pin 5) | Positive Supply | Primary power connection; accepts 1.8–5.5 V; decoupling capacitor placement critical for EMI immunity. |
Key Features
| Feature | Design Value |
|---|---|

Equivalent & Alternatives
The following parts are listed as comparable options for similar operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| LMV316QDBVRQ1 | Lower bandwidth (1 MHz), higher IQ (120 µA), same AEC-Q100 Grade 1 rating and SOT-23-5 package. | Targeted at cost-sensitive, lower-speed body electronics where 10-MHz bandwidth is unnecessary. | Select when bandwidth demand is ≤1 MHz and quiescent current budget allows >120 µA. |
| TSV911QDBVRQ1 | Higher offset (±1.5 mV), wider supply range (2.7–5.5 V), no internal EMI filter, same Grade 1 qualification. | Suitable for general-purpose automotive analog functions where EMI immunity is managed externally. | Select when supply voltage ≥2.7 V and board-level RFI filtering is already implemented. |

FAQ
What automotive qualification level does the OPA316QDBVRQ1 meet?
The OPA316QDBVRQ1 is AEC-Q100 qualified as Grade 1, meaning it operates reliably from –40°C to +125°C ambient temperature and has passed HBM ESD testing at ±4 kV and CDM testing at ±750 V. This qualification makes the OPA316QDBVRQ1 suitable for engine compartment and passenger cabin applications where thermal and electrical stress are significant.
Can the OPA316QDBVRQ1 operate from a 1.8-V single supply?
Yes, the OPA316QDBVRQ1 is fully specified to operate from 1.8 V to 5.5 V total supply voltage. At 1.8 V, it maintains rail-to-rail input common-mode range (V– – 0.2 V to V+), 10-MHz gain bandwidth, and 400 µA quiescent current - enabling direct integration with 1.8-V microcontrollers and energy-harvesting subsystems in modern automotive electronics.
Does the OPA316QDBVRQ1 require external compensation for unity-gain stability?
No, the OPA316QDBVRQ1 is internally compensated for unity-gain stability. Its phase margin is 60° at G = 1, and it exhibits no peaking or oscillation in standard unity-gain follower or inverting configurations. This eliminates the need for external capacitors or resistor networks, simplifying layout and reducing BOM count in space-constrained automotive modules.
How does the internal RFI-EMI filter in the OPA316QDBVRQ1 improve system robustness?
The OPA316QDBVRQ1 integrates an on-chip RFI-EMI rejection filter that attenuates high-frequency interference above 100 MHz without external components. This feature significantly improves immunity to radiated emissions from cellular transceivers, Bluetooth modules, and switching power supplies - reducing susceptibility to erroneous sensor readings or control loop disruption in automotive infotainment and ADAS domains.
What is the maximum output voltage swing of the OPA316QDBVRQ1 at 1.8-V supply?
At 1.8-V supply, the OPA316QDBVRQ1 delivers rail-to-rail output swing within 15 mV of each rail (V– and V+) under 10-kΩ load and –40°C to +125°C conditions. This 1.77-V peak-to-peak linear output range preserves dynamic headroom for precision analog measurements in low-voltage automotive subsystems such as tire pressure monitors and smart junction boxes.
