Product details
Overview
OPA4354AIPWTG4 from Texas Instruments is a quad-channel, rail-to-rail input/output, voltage-feedback CMOS operational amplifier optimized for high-speed video, photodiode transimpedance, and precision analog signal conditioning. 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 supply. It is used in RGB video line drivers and ultrasound front-ends where wide dynamic range and low distortion are critical.
For engineers reviewing the OPA4354AIPWTG4 datasheet, OPA4354AIPWTG4 pinout, OPA4354AIPWTG4 application, or OPA4354AIPWTG4 equivalent, key selection criteria include guaranteed 250-MHz small-signal bandwidth at G = +1, rail-to-rail I/O swing within 100 mV of rails, differential gain/phase of 0.02%/0.09° (NTSC), −84 dB channel-to-channel crosstalk at 5 MHz, and operation across −40°C to +125°C.
Technical Context
The OPA4354AIPWTG4 employs a complementary CMOS input stage enabling rail-to-rail input common-mode range extending 100 mV beyond both supply rails, with seamless transition between N- and P-channel pairs. Its class AB output stage supports ±100 mA continuous output current while maintaining >90 dB open-loop gain up to 125°C.
It is unity-gain stable and specified for single-supply operation (2.5 V to 5.5 V) with thermal shutdown activation at 160°C and recovery at 140°C. All four channels operate independently-no shared biasing or internal coupling-to ensure <−84 dB crosstalk and freedom from inter-channel interaction.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail op amp applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| OPA4354AIPW | Same silicon, identical electrical specs; differs only in tape-and-reel packaging (no G4 suffix) and RoHS compliance marking | No functional difference; suitable for identical use cases including medical and industrial designs requiring full spec compliance | Select OPA4354AIPW when standard RoHS-compliant packaging without green marking is acceptable |
| LMH6629MA/NOPB | Higher 1.5-GHz GBW but lower 100-mA output drive; no rail-to-rail input; higher 2.1 nV/√Hz noise at 10 kHz | Better for RF IF amplification; unsuitable for rail-to-rail sensor interfacing or video line driving due to limited input range | Choose LMH6629MA/NOPB only for GHz-range small-signal gain stages where input swing is constrained above V− + 1.2 V |
Compared with OPA4354AIPWTG4, OPA4354AIPW offers identical performance in non-green packaging, while LMH6629MA/NOPB trades rail-to-rail input and video-optimized distortion for raw bandwidth-making it incompatible for direct replacement in video or low-voltage sensor buffering.

FAQ
What is the maximum operating temperature range for the OPA4354AIPWTG4?
The OPA4354AIPWTG4 is fully specified from −40°C to +125°C ambient temperature, with absolute maximum junction temperature rated at 150°C. Thermal shutdown activates at 160°C and resets at 140°C, providing reliable protection during transient overloads. This range supports deployment in under-hood automotive modules and industrial motor control enclosures where ambient temperatures exceed 100°C.
Does the OPA4354AIPWTG4 support true rail-to-rail input and output operation?
Yes, the OPA4354AIPWTG4 supports true rail-to-rail input with common-mode voltage range from (V−) −0.1 V to (V+) + 0.1 V, and rail-to-rail output with swing within 100 mV of both supply rails under 1-kΩ load. This is achieved via complementary CMOS input pairs and a class AB output stage-enabling full dynamic range utilization in 3.3-V or 5-V single-supply systems without level-shifting circuitry.
What is the channel-to-channel crosstalk specification for the OPA4354AIPWTG4?
The OPA4354AIPWTG4 exhibits −84 dB channel-to-channel crosstalk at 5 MHz, measured input-referred. This value is confirmed in the datasheet's Typical Characteristics section (Figure 29) and results from completely independent circuitry per channel-including separate bias networks and output stages-ensuring no signal coupling between channels A, B, C, and D in multi-channel signal paths.
Can the OPA4354AIPWTG4 drive a 75-Ω video cable directly?
Yes, the OPA4354AIPWTG4 is explicitly characterized for driving 75-Ω back-terminated video cables, delivering 0.02% differential gain and 0.09° differential phase error (NTSC, RL = 150 Ω). Its ±100 mA output current and low 0.05-Ω closed-loop output impedance enable stable operation into reactive video loads without external current-boosting circuitry or peaking networks.
What package type is used for the OPA4354AIPWTG4, and does it require thermal pad connection?
The OPA4354AIPWTG4 uses a 14-pin TSSOP (PW) package with PowerPAD™ thermal enhancement. The exposed thermal pad must be connected to V− (pin 11) or left electrically floating-not tied to ground or any other potential-to ensure proper thermal performance and avoid latch-up. Thermal resistance RθJA is 92.6°C/W, and RθJC(top) is 27.5°C/W per the datasheet.
