Product details
Overview
OPA354AQDBVRQ1 from Texas Instruments is an automotive-grade, single-channel, rail-to-rail input/output CMOS operational amplifier optimized for high-speed video and precision analog signal conditioning. It delivers 250MHz unity-gain bandwidth, 150V/μs slew rate, 6.5nV/√Hz input voltage noise, and ±100mA output drive across 2.5V–5.5V supply, enabling use in ADC input buffers and RGB video line drivers.
For engineers reviewing the OPA354AQDBVRQ1 datasheet, OPA354AQDBVRQ1 pinout, OPA354AQDBVRQ1 application, or OPA354AQDBVRQ1 equivalent, this page provides verified automotive-qualified specs, SOT-23-5 pin mapping, thermal shutdown behavior, differential gain/phase error data, and real-world design context for navigation systems and photodiode transimpedance amplifiers.
Technical Context
The OPA354AQDBVRQ1 employs a complementary rail-to-rail input stage (N- and P-channel parallel differential pairs) extending common-mode range 100mV beyond rails, and a class-AB output stage delivering 100mV rail-to-rail swing into high-impedance loads. Its unity-gain stability supports direct use in buffer configurations without external compensation.
It integrates on-chip thermal shutdown (trip at 160°C, reset at 140°C), operates over –40°C to +125°C ambient, and achieves 0.02% differential gain / 0.09° differential phase error per NTSC standard-critical for automotive video processing where signal fidelity directly impacts display integrity and driver-assist system reliability.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 250MHz - enables stable operation as unity-gain buffer for signals up to 100MHz with ≤0.1dB flatness. |
| Slew Rate | 150V/μs - supports clean 2V step response in ≤30ns (0.1%) and ≤60ns (0.01%), suitable for driving medium-speed ADCs. |
| Input Voltage Noise | 6.5nV/√Hz at 1MHz - low enough to preserve SNR in photodiode transimpedance amplifiers with >10kΩ feedback resistors. |
| Output Drive | ±100mA continuous - drives 75Ω back-terminated video cables or laser diodes without external boost circuitry. |
| Rail-to-Rail I/O | Input extends (V−) − 0.1V to (V+) + 0.1V; output swings within 100mV of rails - maximizes dynamic range in single-supply 3.3V or 5V systems. |
| Quiescent Current | 5mA per channel at 25°C - balances speed and power for always-on automotive subsystems requiring low standby consumption. |
| Differential Gain/Phase | 0.02% / 0.09° (NTSC, RL = 150Ω) - meets broadcast-grade video fidelity requirements for infotainment displays and camera modules. |
Pinout & Package
OPA354AQDBVRQ1 is housed in a 5-pin SOT-23 (DBV) package measuring 2.90mm × 1.60mm, optimized for space-constrained automotive PCB layouts and reflow-compatible assembly.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| OUT (Pin 1) | Output | Class-AB buffered voltage source capable of ±100mA drive and 100mV rail-to-rail swing; requires series resistor for large capacitive loads. |
| V− (Pin 2) | Negative Supply | Lowest potential node; accepts ground or negative rail; common reference for input common-mode and output swing. |
| +IN (Pin 3) | Noninverting Input | High-impedance (10¹³ Ω || 2pF) node accepting signals up to (V−) − 0.1V and (V+) + 0.1V; uses P-channel pair near V−, N-channel near V+. |
| −IN (Pin 4) | Inverting Input | Matches +IN in impedance and common-mode range; forms differential pair with +IN for precision gain control in closed-loop configurations. |
| V+ (Pin 5) | Positive Supply | Highest potential node; supplies 2.5V–5.5V; powers internal biasing, input stages, and output driver; must be decoupled with 0.1µF ceramic capacitor. |
Key Features
| Feature | Design Value |
|---|---|
| AEC-Q100 Grade 1 Qualification | Validated for –40°C to +125°C ambient operation with full electrical characterization - eliminates qualification overhead for Tier 1 automotive designs. |
| Thermal Shutdown Protection | Automatic disable at 160°C junction temperature with 20°C hysteresis - prevents permanent damage during sustained overload or poor heatsinking. |
| 0.1dB Gain Flatness to 40MHz | Ensures amplitude consistency across HD video baseband (e.g., RGB, YPbPr) without post-amplifier equalization. |
| Low Input Bias Current (3pA) | Minimizes DC error in high-impedance sensor interfaces (e.g., photodiodes, piezoelectric elements) and long RC time constants. |
| Channel Independence (Single Channel) | No crosstalk concerns - simplifies layout and eliminates inter-channel interference in critical analog signal paths like radar front-ends. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed op-amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA355QDBVRQ1 | 200MHz GBW, rail-to-rail output only (not input), 125mA output drive, same SOT-23-5 package. | Lacks rail-to-rail input - unsuitable for signals near supply rails; lower bandwidth limits video flatness to 30MHz. | Select when rail-to-rail input is not required and 200MHz suffices; verify input common-mode range compatibility. |
| LMH6629MA/NOPB | 1.5GHz GBW, 900V/μs slew rate, 1.8nV/√Hz noise, SOIC-8 package, non-automotive grade. | Higher speed/noise performance but no AEC-Q100 qualification; larger footprint and higher quiescent current (12mA). | Use only in non-automotive industrial test equipment; not qualified for vehicle deployment or extended temperature operation. |
Compared with OPA354AQDBVRQ1, OPA355QDBVRQ1 trades 50MHz bandwidth and rail-to-rail input for marginally higher output current, while LMH6629MA/NOPB offers extreme bandwidth at the cost of automotive qualification, power efficiency, and package size-making OPA354AQDBVRQ1 the optimal balance for production automotive signal chains.

FAQ
What is the operating temperature range for OPA354AQDBVRQ1?
The OPA354AQDBVRQ1 is qualified for automotive Grade 1 operation, with a specified ambient operating temperature range of –40°C to +125°C. All electrical parameters-including gain-bandwidth, slew rate, and input offset voltage-are fully characterized across this range, and thermal shutdown activates at 160°C junction temperature to protect the device under fault conditions.
Does OPA354AQDBVRQ1 support single-supply operation?
Yes, OPA354AQDBVRQ1 supports true single-supply operation from 2.5V to 5.5V. Its rail-to-rail input stage accepts common-mode voltages from (V−) − 0.1V to (V+) + 0.1V, and its rail-to-rail output swings within 100mV of both supply rails-enabling direct interfacing with 3.3V or 5V microcontrollers and ADCs without level-shifting circuitry.
Can OPA354AQDBVRQ1 drive a 75Ω video load?
Yes, OPA354AQDBVRQ1 is explicitly characterized for 75Ω back-terminated video loads, delivering 0.02% differential gain error and 0.09° differential phase error per NTSC standard. When configured as a single-supply line driver (e.g., with 2.5V common-mode bias), it maintains full video fidelity up to 40MHz and supplies sufficient current to sustain signal levels across standard coaxial cable runs.
What is the maximum continuous output current for OPA354AQDBVRQ1?
The OPA354AQDBVRQ1 provides ±100mA continuous output current per channel, verified across the full –40°C to +125°C temperature range. This rating applies under steady-state DC conditions; peak short-circuit current reaches ~200mA, triggering thermal shutdown if sustained. For loads requiring >100mA, TI recommends paralleling multiple OPA354AQDBVRQ1 devices with matched feedback networks.
Is OPA354AQDBVRQ1 pin-compatible with other members of the OPAx354-Q1 family?
No, OPA354AQDBVRQ1 is not pin-compatible with OPA2354A-Q1 (VSSOP-8) or OPA4354-Q1 (TSSOP-14). It uses the 5-pin SOT-23-5 (DBV) package with unique pinout: OUT (1), V− (2), +IN (3), −IN (4), V+ (5). Pin compatibility exists only within the same channel count and package variant-e.g., OPA354AQDBVRQ1 and OPA354AIDBVR share identical DBV pinout and footprint.
