Product details
Overview
OPA2354AQDGKRQ1 from Texas Instruments is a dual-channel, automotive-grade, rail-to-rail input/output CMOS operational amplifier optimized for high-speed video, transimpedance, and ADC/DAC interface applications. It delivers 250MHz unity-gain bandwidth, 150V/µs slew rate, 6.5nV/√Hz input voltage noise, ±100mA output drive, and operates from 2.5V to 5.5V supply across –40°C to +125°C.
For engineers reviewing the OPA2354AQDGKRQ1 datasheet, OPA2354AQDGKRQ1 pinout, OPA2354AQDGKRQ1 application, or OPA2354AQDGKRQ1 equivalent, this page provides verified technical context, automotive-qualified specifications, dual-channel crosstalk performance (–100dB at 5MHz), thermal shutdown behavior, and real-world design meaning for video line driving, photodiode amplification, and high-speed signal conditioning.
Technical Context
The OPA2354AQDGKRQ1 uses a complementary rail-to-rail input stage with N- and P-channel differential pairs enabling common-mode operation 100mV beyond both supply rails, and a class-AB output stage delivering 100mV rail-to-rail swing into high-impedance loads. Its unity-gain stability and 250MHz f−3dB support wideband closed-loop configurations without external compensation.
It features independent channel circuitry in the VSSOP-8 package to minimize inter-channel crosstalk (–100dB at 5MHz), integrated thermal shutdown (trip at 160°C, reset at 140°C), and low 3pA input bias current-critical for precision transimpedance designs with photodiodes up to ~10pF capacitance.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 250MHz - enables stable G = +1 video buffers and fast-settling ADC drivers without peaking. |
| Slew Rate | 150V/µs - supports clean 2V step response in ≤11ns (10%–90%), critical for pulse fidelity in radar front-ends. |
| Input Voltage Noise | 6.5nV/√Hz at 1MHz - minimizes signal degradation in low-level photodiode transimpedance amplifiers. |
| Output Drive | ±100mA continuous - drives 75Ω back-terminated video cables or laser diodes directly without external buffers. |
| 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. |
| Channel Crosstalk | −100dB at 5MHz - ensures isolated signal paths in dual-channel active filters or stereo video processing. |
| Quiescent Current | 5mA per channel at 25°C - balances speed and power in battery-sensitive automotive infotainment modules. |
Pinout & Package
VSSOP-8 (DGK) package: 3.00mm × 3.00mm body, 0.5mm pitch, exposed thermal pad (not electrically connected), RoHS-compliant, designed for automotive PCB reliability under thermal cycling.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| +IN A (Pin 3) | Noninverting input, Channel A | Accepts signals up to (V−) −0.1V or (V+) +0.1V; enables DC-coupled sensor interfaces with full supply-range common-mode. |
| +IN B (Pin 5) | Noninverting input, Channel B | Independent of Channel A; supports dual-path signal conditioning without shared input-stage interaction. |
| −IN A (Pin 2) | Inverting input, Channel A | Used in transimpedance or inverting gain configurations; low 3pA bias current preserves photodiode accuracy. |
| −IN B (Pin 6) | Inverting input, Channel B | Electrically isolated from Channel A inputs; maintains >100dB crosstalk rejection at video frequencies. |
| OUT A (Pin 1) | Output, Channel A | Delivers ±100mA into 75Ω or 1kΩ loads; 100mV rail margin supports 3.3V logic-compatible swing in single-supply systems. |
| OUT B (Pin 7) | Output, Channel B | Matches OUT A performance; enables simultaneous RGB video buffering or dual ADC channel driving. |
| V+ (Pin 8) | Positive supply | Accepts 2.5V–5.5V; supplies both channels; internal regulation ensures consistent biasing across temperature. |
| V− (Pin 4) | Negative supply / Ground reference | Supports single-supply (V− = GND) or split-supply (V− = −1.25V) operation; referenced for all input/output swing metrics. |
Key Features
| Feature | Design Value |
|---|---|
| Automotive qualification | AEC-Q100 Grade 1 (–40°C to +125°C ambient), qualified for safety-critical navigation and radar ECUs. |
| Video performance | Differential gain error 0.02% and phase error 0.09° - meets NTSC/PAL broadcast standards for analog video routing. |
| 0.1dB gain flatness | 40MHz - ensures amplitude integrity across HD video baseband (0–30MHz) without equalization. |
| Thermal shutdown | Active protection at 160°C junction temperature with automatic recovery at 140°C - prevents latch-up in engine bay environments. |
| Low input bias current | 3pA typical - enables high-impedance photodiode or capacitive sensor interfaces without significant offset drift. |

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 |
|---|---|---|---|
| OPA2355QDGKRQ1 | 200MHz GBW, rail-to-rail output only (not input), 10nV/√Hz noise, 10mA quiescent current | Lacks rail-to-rail input - unsuitable for DC-coupled sensor interfaces near supply rails | Select when lower noise is acceptable and input common-mode range is constrained to mid-supply. |
| LMH6629MA/NOPB | 1.5GHz GBW, 900V/µs slew, 1.9nV/√Hz noise, ±30mA output, no AEC-Q100 qualification | Higher speed/noise performance but unqualified for automotive use; requires external thermal management | Choose for non-automotive test equipment requiring >1GHz bandwidth, not for production vehicle ECUs. |
Compared with OPA2354AQDGKRQ1, OPA2355QDGKRQ1 trades input rail-to-rail capability and lower power for reduced bandwidth and higher noise, while LMH6629MA/NOPB offers extreme speed at the cost of automotive qualification and higher supply current-making OPA2354AQDGKRQ1 the balanced choice for AEC-Q100-compliant high-fidelity signal chains.

FAQ
What is the operating temperature range for OPA2354AQDGKRQ1?
The OPA2354AQDGKRQ1 is qualified for automotive applications per AEC-Q100 Grade 1, with a specified ambient operating temperature range of –40°C to +125°C. All electrical parameters-including bandwidth, slew rate, and input offset-are guaranteed across this full range, making it suitable for under-hood and dashboard ECU deployments where thermal stress is severe.
Does OPA2354AQDGKRQ1 support single-supply operation?
Yes, OPA2354AQDGKRQ1 supports true single-supply operation from 2.5V to 5.5V. Its rail-to-rail input extends 100mV beyond both supply rails, and its output swings within 100mV of each rail-enabling direct interfacing with 3.3V or 5V microcontrollers and ADCs without level-shifting circuitry.
What is the maximum capacitive load OPA2354AQDGKRQ1 can drive stably?
OPA2354AQDGKRQ1 remains stable driving ≥100pF capacitive loads in unity-gain configuration when a 10Ω–20Ω series resistor (RS) is added at the output, as documented in Figure 5-14 of the datasheet. Without RS, stability degrades above ~20pF; with RS, it sustains flat frequency response up to 100pF while maintaining >45° phase margin.
How does OPA2354AQDGKRQ1 handle thermal overload?
OPA2354AQDGKRQ1 integrates an on-chip thermal shutdown circuit that disables both amplifiers when junction temperature reaches 160°C. Operation resumes automatically once the die cools to 140°C. This protects against permanent damage during sustained overdrive or poor PCB heat sinking-critical in compact automotive modules with limited airflow.
Is OPA2354AQDGKRQ1 pin-compatible with other OPAx354-Q1 variants?
No-OPA2354AQDGKRQ1 uses the 8-pin VSSOP (DGK) package with dedicated dual-channel pins, while OPA354AQDBVRQ1 uses 5-pin SOT-23 and OPA4354QPWRQ1 uses 14-pin TSSOP. Pin functions differ across packages; PCB layout must match DGK footprint and pin mapping shown in Figure 4-2 of the datasheet.
