Product details
Overview
OPA356AQDBVRQ1 from Texas Instruments is an AEC-Q100 qualified automotive-grade CMOS operational amplifier optimized for high-speed video and precision signal conditioning. It delivers 200-MHz gain-bandwidth, 360 V/µs slew rate, 5.8 nV/√Hz input voltage noise, rail-to-rail output swing within 100 mV of rails, and operates from 2.5 V to 5.5 V single supply - enabling use in ADAS camera front-ends and radar signal chains.
For engineers reviewing the OPA356AQDBVRQ1 datasheet, OPA356AQDBVRQ1 pinout, OPA356AQDBVRQ1 application, or OPA356AQDBVRQ1 equivalent, key selection criteria include unity-gain stability, –40°C to 125°C operation, low input bias current (3 pA), thermal shutdown protection, and 75 MHz 0.1-dB gain flatness for composite video fidelity.
Technical Context
The OPA356AQDBVRQ1 employs a voltage-feedback CMOS architecture with Class AB output stage, supporting stable unity-gain operation and driving up to ±60 mA continuous output current into resistive loads. Its input common-mode range extends 100 mV below ground and up to 1.5 V below V+, enabling true single-supply interfacing with sensors and ADCs.
Internal thermal shutdown activates at 160°C junction temperature and resets at 140°C, while ESD robustness meets AEC-Q100 Level HBM ±2 kV and CDM ±500 V. The device maintains 0.02% differential gain and 0.05° differential phase error under NTSC video load conditions (RL = 150 Ω).
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Gain-bandwidth product | 200 MHz - supports stable closed-loop amplification up to 200× gain at 1 MHz or 2× gain at 100 MHz. |
| Slew rate | 360 V/µs - enables distortion-free reproduction of fast 4-V step signals in <8 ns rise time (10–90%). |
| Input voltage noise density | 5.8 nV/√Hz at 1 MHz - critical for low-noise transimpedance amplifiers with photodiodes or high-Z sensors. |
| Input bias current | 3 pA typical - minimizes voltage error across sensor source impedances up to 10 MΩ. |
| Output swing | Within 100 mV of rails (at RL = 150 Ω) - preserves >96% dynamic range on 5-V supply for ADC interface. |
| Supply voltage range | 2.5 V to 5.5 V single supply - compatible with automotive 3.3-V and 5-V domains without level-shifting. |
| Operating temperature | –40°C to +125°C ambient - qualified per AEC-Q100 Grade 1 for engine bay and ADAS ECU deployment. |
Pinout & Package
SOT-23-5 (DBV) package: 2.90 mm × 1.60 mm body, 0.95 mm height, surface-mount, lead-free and RoHS compliant.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 - Out | Amplifier output | Capable of ±60 mA continuous drive; rail-to-rail swing within 100 mV; requires external 0.1-µF bypass capacitor near pin. |
| 2 - V– | Negative power supply | May be grounded in single-supply mode; supports dual-supply operation down to –2.75 V; connects to PCB ground plane. |
| 3 - +In | Noninverting input | High-impedance CMOS node (10¹³ Ω || 1.5 pF); accepts DC-bias for single-supply photodiode interfaces. |
| 4 - –In | Inverting input | Summing junction for transimpedance and active filter configurations; sensitive to stray capacitance & board leakage. |
| 5 - V+ | Positive power supply | Accepts 2.5–5.5 V; internal bandgap reference derived from this rail; requires local 0.1-µF ceramic decoupling. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to 125°C), HBM ±2 kV, CDM ±500 V - certified for safety-critical infotainment and ADAS control units. |
| Video performance | 0.02% differential gain / 0.05° differential phase error at NTSC - meets broadcast-grade analog video linearity requirements. |
| Unity-gain stability | Stable with G = 1 configuration and no external compensation - simplifies design of voltage followers and buffer stages. |
| Rail-to-rail output | Swings to within 100 mV of V+ and V– - maximizes signal headroom for 12-bit+ ADC drivers without negative supply. |
| Thermal protection | Shuts down at 160°C junction temperature; auto-resumes at 140°C - prevents permanent damage during overload or poor heatsinking. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed operational amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA2356QDGKRQ1 | Dual-channel version in VSSOP-8; identical electrical specs but higher quiescent current (16.6 mA vs 8.3 mA per channel). | Better suited for space-constrained dual-path systems (e.g., stereo camera processing) where layout reuse is prioritized. | Select when dual-channel functionality is required and PCB area allows VSSOP-8 footprint. |
| LMH6629MA/NOPB | Higher 1.5 GHz GBW and 940 V/µs slew rate; wider 2.7–12.6 V supply range; not AEC-Q100 qualified. | Applicable in non-automotive test equipment or industrial imaging where extreme speed outweighs qualification needs. | Choose only for non-automotive designs requiring >1 GHz bandwidth; not suitable for automotive production. |
Compared with OPA356AQDBVRQ1, the dual-channel OPA2356QDGKRQ1 offers identical per-channel performance in a different package, while LMH6629MA/NOPB trades automotive qualification for higher speed - making OPA356AQDBVRQ1 the optimal balance of speed, noise, and AEC-Q100 compliance for vehicle electronics.

FAQ
What is the maximum operating supply voltage for OPA356AQDBVRQ1?
The absolute maximum supply voltage (V+ to V–) for OPA356AQDBVRQ1 is 7.5 V. Operation beyond this risks permanent damage. The recommended operating range is 2.5 V to 5.5 V single supply or ±1.25 V to ±2.75 V dual supply. At 5.5 V, the device delivers full specified performance including 360 V/µs slew rate and 200-MHz GBW. Exceeding 7.5 V violates Absolute Maximum Ratings per SBOS479A.
Does OPA356AQDBVRQ1 support true single-supply operation with input referenced to ground?
Yes, OPA356AQDBVRQ1 supports true single-supply operation with input common-mode range extending 100 mV below ground (V–). This allows direct connection of ground-referenced sensors or video sources without level-shifting circuitry. The input stage remains linear and accurate across this range, and the rail-to-rail output swings within 100 mV of V– (ground) and V+, preserving dynamic range in 3.3-V or 5-V systems.
What is the thermal shutdown behavior of OPA356AQDBVRQ1?
OPA356AQDBVRQ1 activates thermal shutdown at 160°C junction temperature and automatically resumes normal operation when junction temperature cools to 140°C. This hysteresis prevents oscillation near trip point. Shutdown is implemented via internal circuitry that disables the output stage; quiescent current drops significantly during shutdown. The device is rated for continuous operation up to 125°C ambient, with RθJA = 185°C/W in SOT-23-5 package.
Can OPA356AQDBVRQ1 drive a 75-Ω back-terminated video cable directly?
Yes, OPA356AQDBVRQ1 is explicitly characterized to drive standard 75-Ω back-terminated video cables, presenting a 150-Ω resistive load. Its output stage delivers ±60 mA continuous current and supports 0.02% differential gain / 0.05° differential phase error under NTSC conditions. For optimal video fidelity, maintain proper PCB layout with controlled impedance traces and avoid capacitive loading exceeding 100 pF without series resistance compensation.
Is OPA356AQDBVRQ1 pin-compatible with other members of the OPA356-Q1 family?
Yes, all OPA356-Q1 variants - including OPA356AQDBVRQ1 (SOT-23-5), OPA2356QDGKRQ1 (VSSOP-8 dual), and OPA4356QYPPRQ1 (TSSOP-14 quad) - share identical pin functions per channel. The SOT-23-5 pinout (Out, V–, +In, –In, V+) maps directly to corresponding pins in multi-channel packages. This enables scalable design reuse across single/dual/quad configurations without schematic or layout redesign.
