Product details
Overview
OPA2354AIDDARG3 from Texas Instruments is a dual-channel, rail-to-rail input/output, 250-MHz unity-gain stable CMOS operational amplifier optimized for high-speed video and precision analog signal conditioning. It delivers 150 V/µs slew rate, 6.5 nV/√Hz input voltage noise, ±100 mA output current per channel, and operates from 2.5 V to 5.5 V supply - enabling use in 3.3-V and 5-V systems such as RGB video line drivers and photodiode transimpedance amplifiers.
For engineers reviewing the OPA2354AIDDARG3 datasheet, OPA2354AIDDARG3 pinout, OPA2354AIDDARG3 application, or OPA2354AIDDARG3 equivalent, key selection criteria include its 100-MHz gain-bandwidth product, −40°C to +125°C extended temperature range, VSSOP-8 package footprint, differential gain/phase performance (0.02%/0.09°), and channel-to-channel crosstalk of −100 dB at 5 MHz.
Technical Context
The OPA2354AIDDARG3 employs complementary N- and P-channel input stages to achieve rail-to-rail common-mode input range extending 100 mV beyond both supply rails, with seamless transition between input pairs. Its class AB output stage supports rail-to-rail swing within 100 mV of rails under 1-kΩ load and sustains ±100 mA continuous output current per channel.
It features on-chip thermal shutdown activation at 160°C junction temperature and automatic recovery at 140°C. The device is unity-gain stable and specified across the full −40°C to +125°C industrial temperature range with guaranteed 0.1-dB gain flatness to 40 MHz and harmonic distortion below −75 dBc (2nd) / −83 dBc (3rd) at 1 MHz.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Unity-Gain Bandwidth | 250 MHz - enables stable operation as voltage follower in high-frequency signal paths without external compensation |
| Slew Rate | 150 V/µs - supports clean 2-V step response in ≤11 ns with <0.1% settling in 30 ns, critical for fast ADC/DAC buffering |
| Input Voltage Noise | 6.5 nV/√Hz - low-noise performance preserves SNR in photodiode transimpedance and ultrasound receive chains |
| Output Current | ±100 mA per channel - drives 75-Ω back-terminated video cables or laser diodes directly without external buffers |
| Supply Range | 2.5 V to 5.5 V - compatible with single-supply 3.3-V and 5-V systems, including portable and industrial embedded platforms |
| Operating Temperature | −40°C to +125°C - qualified for automotive under-hood, industrial control, and harsh-environment applications |
| Differential Gain/Phase | 0.02% / 0.09° - meets broadcast video standards (NTSC) for minimal color fidelity degradation in RGB drivers |
Pinout & Package
The OPA2354AIDDARG3 is housed in an 8-pin VSSOP (DGK) package measuring 3.00 mm × 3.00 mm with exposed thermal pad. This thermally enhanced surface-mount package supports high-power-density PCB layouts and improves heat dissipation in compact designs.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - connects to load or next stage; requires proper decoupling and layout for stability at >100 MHz |
| 2 | –IN A | Inverting input, channel A - forms feedback node in inverting configurations; sensitive to parasitic capacitance |
| 3 | +IN A | Noninverting input, channel A - high-impedance node; must be routed away from noisy signals to minimize offset drift |
| 4 | V– | Negative supply rail - serves as reference ground for dual-supply operation or system ground in single-supply mode |
| 5 | +IN B | Noninverting input, channel B - electrically isolated from channel A; enables independent signal processing paths |
| 6 | –IN B | Inverting input, channel B - shares no internal circuitry with channel A, ensuring <−100 dB crosstalk at 5 MHz |
| 7 | OUT B | Amplifier B output - fully independent output stage; supports simultaneous high-speed operation with channel A |
| 8 | V+ | Positive supply rail - must be bypassed with ≥1 µF ceramic capacitor near pin to suppress supply-induced noise |
Key Features
| Feature | Design Value |
|---|---|
| Rail-to-rail I/O | Input common-mode extends 100 mV beyond supplies; output swings to within 100 mV of rails under 1-kΩ load - maximizes dynamic range in low-voltage systems |
| Thermal shutdown | Activates at 160°C junction temperature and resets at 140°C - protects against sustained overload or poor heatsinking in sealed enclosures |
| Low input bias current | 3 pA typical - minimizes voltage error in high-impedance sensor interfaces (e.g., photodiodes, pH electrodes) |
| High-speed video performance | 0.1-dB gain flatness to 40 MHz and differential phase/gain errors of 0.09°/0.02% - preserves color fidelity in SD/HD video transmission |
| Quiescent current | 4.9 mA per channel at 5 V - balances speed and power efficiency for battery-sensitive or thermally constrained applications |

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 |
|---|---|---|---|
| OPA2355IDGKR | 200-MHz GBW, rail-to-rail output only (not input), 105 V/µs slew rate, 7 nV/√Hz noise | Limited common-mode input range reduces flexibility in level-shifting or single-supply sensor interfaces | Choose when lower power (3.6 mA/ch) and cost are prioritized over rail-to-rail input and highest slew rate |
| LMH6629MA/NOPB | 1.5-GHz GBW, 940 V/µs slew rate, 1.9 nV/√Hz noise, but not rail-to-rail I/O and higher quiescent current (12.5 mA/ch) | Requires dual supplies or level-shifting circuitry; better suited for RF/IF gain blocks than video or precision analog | Choose for ultra-wideband applications where noise and speed outweigh supply simplicity and output swing requirements |
Compared with OPA2354AIDDARG3, OPA2355IDGKR trades bandwidth and input range for lower power, while LMH6629MA/NOPB delivers extreme speed and noise performance at the expense of supply flexibility and layout complexity - making OPA2354AIDDARG3 optimal for balanced high-speed, low-voltage, rail-to-rail signal conditioning.

FAQ
What is the maximum continuous output current per channel for OPA2354AIDDARG3?
The OPA2354AIDDARG3 supports ±100 mA continuous output current per channel under recommended operating conditions (VS = 5 V, TA ≤ +125°C). This rating is validated across the full temperature range and enables direct driving of 75-Ω video loads or laser diodes without external boost stages. Exceeding this current continuously may trigger thermal shutdown at 160°C junction temperature.
Does OPA2354AIDDARG3 support single-supply operation?
Yes, OPA2354AIDDARG3 operates from a single supply of 2.5 V to 5.5 V. Its rail-to-rail input extends 100 mV beyond both supply rails, and its output swings within 100 mV of the rails under 1-kΩ load - making it ideal for 3.3-V and 5-V single-supply systems such as portable medical devices and industrial sensors. No level-shifting circuitry is required for most signal conditioning tasks.
What is the guaranteed gain-bandwidth product for OPA2354AIDDARG3?
The guaranteed gain-bandwidth product (GBW) for OPA2354AIDDARG3 is 100 MHz, specified over the full −40°C to +125°C temperature range and supply voltages from 2.7 V to 5.5 V. This ensures predictable closed-loop bandwidth in noninverting configurations (e.g., G = +10 yields ~10 MHz bandwidth), supporting stable high-frequency filtering and signal conditioning without external compensation.
How does thermal shutdown function in OPA2354AIDDARG3?
OPA2354AIDDARG3 incorporates an on-chip thermal shutdown circuit that disables both amplifier channels when junction temperature reaches 160°C. Operation resumes automatically once the die cools to approximately 140°C. This protection is independent of supply voltage and remains active across the full operating temperature range, safeguarding the device during sustained overload or inadequate PCB thermal design.
Is OPA2354AIDDARG3 pin-compatible with other members of the OPAx354 family?
No - OPA2354AIDDARG3 uses the 8-pin VSSOP (DGK) package, while the single-channel OPA354 is offered in SOT-23 (5-pin) and HSOP (8-pin), and the quad OPA4354 uses SOIC/TSSOP (14-pin). Pin functions differ across variants: OPA2354AIDDARG3 has dedicated pins for both channels' inputs and outputs, whereas OPA354 consolidates to five pins. Board redesign is required when substituting between family members.
