Product details
Overview
OPA2354AIDDAR from Texas Instruments is a dual-channel, rail-to-rail input/output, voltage-feedback CMOS operational amplifier optimized for high-speed video, photodiode transimpedance, and analog-to-digital converter (ADC) buffer applications. It delivers 250-MHz unity-gain bandwidth, 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 single supply.
For engineers reviewing the OPA2354AIDDAR datasheet, OPA2354AIDDAR pinout, OPA2354AIDDAR application, or OPA2354AIDDAR equivalent, key selection criteria include its 100-mA continuous output drive capability in VSSOP-8 package, −40°C to +125°C extended temperature range, differential gain/phase of 0.02%/0.09° for composite video, and channel-to-channel crosstalk of −100 dB at 5 MHz.
Technical Context
The OPA2354AIDDAR uses a complementary CMOS input stage enabling rail-to-rail input operation with common-mode range extending 100 mV beyond both supply rails. Its class AB output stage supports rail-to-rail output swing within 100 mV of rails under 1-kΩ load and maintains >94 dB open-loop gain across −40°C to +125°C.
It features on-chip thermal shutdown activation at 160°C and reset at 140°C, low 4.9 mA per-channel quiescent current, and independent dual-channel architecture ensuring minimal inter-channel crosstalk - critical for multi-signal conditioning in imaging and communications systems.
Key Specifications

| Slew Rate | 150 V/µs - supports fast transient response for 2-V step signals with ≤30 ns 0.1% settling time. |
| Input Voltage Noise | 6.5 nV/√Hz at 1 MHz - preserves signal integrity in low-level photodiode transimpedance amplifiers. |
| Output Current | ±100 mA per channel - drives 75-Ω back-terminated video cables or parallel laser diode loads directly. |
| Supply Range | 2.5 V to 5.5 V - compatible with modern low-voltage digital logic and mixed-signal SoC interfaces. |
| Operating Temp | −40°C to +125°C - qualified for automotive front-end modules, industrial vision sensors, and medical ultrasound subsystems. |
| Differential Gain/Phase | 0.02% / 0.09° - meets NTSC/PAL broadcast video fidelity requirements without post-correction. |
Pinout & Package
The OPA2354AIDDAR 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 efficient heat dissipation in space-constrained applications.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUT A | Amplifier A output - connects directly to 75-Ω video load or ADC input; requires local 0.1-µF bypass capacitor. |
| 2 | –IN A | Inverting input, channel A - used for inverting gain stages or feedback networks in active filters. |
| 3 | +IN A | Noninverting input, channel A - accepts high-impedance sensor signals (e.g., photodiode anode) with rail-to-rail common-mode range. |
| 4 | V– | Negative supply terminal - must be connected to ground or lowest system potential; ties PowerPAD for thermal performance. |
| 5 | +IN B | Noninverting input, channel B - electrically isolated from channel A; enables dual-path signal conditioning without interaction. |
| 6 | –IN B | Inverting input, channel B - supports independent gain configuration for second signal path (e.g., green/blue RGB channels). |
| 7 | OUT B | Amplifier B output - provides matched AC performance to OUT A; shares same supply rejection and noise floor. |
| 8 | V+ | Positive supply terminal - accepts 2.5–5.5 V; requires low-ESR ceramic decoupling adjacent to pin. |
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 - maximizes dynamic range in single-supply 3.3-V or 5-V systems. |
| Low Input Bias Current | 3 pA typical - minimizes offset error in high-impedance photodiode or capacitive sensor interfaces. |
| Thermal Shutdown | Activates at 160°C junction temperature and resets at 140°C - prevents permanent damage during sustained overload or poor heatsinking. |
| Channel Isolation | −100 dB crosstalk at 5 MHz - ensures independent operation of dual channels in RGB video or stereo audio paths. |
| Video-Optimized Performance | 0.1-dB gain flatness to 40 MHz and <0.1° phase error - eliminates color distortion in SD/HD video transmission. |

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 |
|---|---|---|---|
| OPA2354AIDGKR | Same electrical specs; VSSOP-8 package with tape-and-reel packaging (no lead-free finish difference) | Identical functional use; differs only in reel quantity and moisture sensitivity level (MSL) | Select when standard reel size (2500 pcs) and MSL-2a compliance are required for SMT production. |
| LMH6629MA/NOPB | Higher 1.5-GHz GBW but higher 12.5 mA IQ; no rail-to-rail input; SOIC-8 only | Better for RF IF amplification above 100 MHz; unsuitable for rail-to-rail sensor interfaces or video DC coupling | Choose only when bandwidth >500 MHz is mandatory and input common-mode range flexibility is not needed. |
Compared with OPA2354AIDDAR, OPA2354AIDGKR offers identical performance in alternate packaging for volume manufacturing, while LMH6629MA/NOPB trades rail-to-rail capability and power efficiency for ultra-wideband gain-making it suitable only for narrow high-frequency signal chains where DC precision is secondary.

FAQ
What is the maximum continuous output current per channel for OPA2354AIDDAR?
The OPA2354AIDDAR 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 −40°C to +125°C temperature range and enables direct driving of 75-Ω video loads or parallel-connected laser diodes without external current boosting. Exceeding this limit risks triggering thermal shutdown at 160°C junction temperature.
Does OPA2354AIDDAR support true rail-to-rail input and output operation?
Yes, OPA2354AIDDAR supports true rail-to-rail input with common-mode voltage range extending 100 mV beyond both supply rails (V− −0.1 V to V+ +0.1 V), and rail-to-rail output with swing within 100 mV of each rail under 1-kΩ load. This capability is achieved via complementary CMOS input pairs and a class AB output stage - confirmed in TI's SBOS233G datasheet Figures 20 and 22 across temperature and supply variations.
What is the small-signal bandwidth and gain-bandwidth product of OPA2354AIDDAR?
The OPA2354AIDDAR has a small-signal −3-dB bandwidth of 250 MHz at unity gain and a gain-bandwidth product (GBW) of 100 MHz at G = +10. These values are measured per TI SBOS233G Section 7.7 with VO = 100 mVPP, RL = 1 kΩ, and VS = 5 V. The device remains unity-gain stable without external compensation, making it suitable for high-speed voltage followers and broadband amplifiers.
Can OPA2354AIDDAR operate from a 3.3-V single supply?
Yes, OPA2354AIDDAR is fully specified for operation from 2.5 V to 5.5 V single supply, including 3.3 V. At VS = 3.3 V, it maintains 110 V/µs slew rate (typical), 200-MHz small-signal bandwidth, and rail-to-rail I/O functionality. Quiescent current drops to ~4.5 mA per channel, and output swing remains within 120 mV of rails under 1-kΩ load - verified in SBOS233G Electrical Characteristics tables and Figure 21.
What is the channel-to-channel crosstalk specification for OPA2354AIDDAR?
The OPA2354AIDDAR exhibits −100 dB channel-to-channel crosstalk at 5 MHz, as measured per TI SBOS233G Section 7.7. This value reflects isolation between Channel A and Channel B under small-signal conditions and confirms complete independence of internal circuitry - essential for dual-path applications such as RGB video drivers or stereo sensor signal chains where signal leakage must remain below −100 dB.
