Product details

Overview

OPA4354AIPWR 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 single supply - enabling wide dynamic range in compact 14-pin TSSOP systems.

For engineers reviewing the OPA4354AIPWR datasheet, OPA4354AIPWR pinout, OPA4354AIPWR application, or OPA4354AIPWR equivalent, key selection criteria include guaranteed rail-to-rail I/O swing within 100 mV of rails at 1 kΩ load, −84 dB channel-to-channel crosstalk at 5 MHz, thermal shutdown protection (160°C trip), and operation across −40°C to +125°C industrial temperature range.

Technical Context

The OPA4354AIPWR employs a complementary N/P-channel input stage enabling rail-to-rail common-mode input range extending 100 mV beyond both supply rails, and a Class AB output stage supporting rail-to-rail output swing with >100 mA continuous drive capability per amplifier. Its unity-gain stability and 100-MHz gain-bandwidth product support high-fidelity closed-loop configurations up to G = +10.

Each of the four independent amplifiers features identical electrical characteristics - including matched offset voltage drift (±4 µV/°C), low input bias current (3 pA typ), and differential gain/phase error of 0.02% / 0.09° under NTSC video loading - ensuring minimal interaction and consistent performance across multichannel signal paths.

Pinout & Package

OPA4354AIPWR is packaged in a 14-pin TSSOP (PW package) with 5.00 mm × 4.40 mm body size and exposed pad for thermal enhancement. Pin 1 is channel A output; pins 2/3, 5/6, 9/10, and 12/13 are inverting/non-inverting inputs for channels A–D respectively; pins 1, 7, 8, and 14 are outputs; pin 4 is V+; pin 11 is V−.

Pin/Terminal	Circuit Role	Design Meaning
1	OUT A	Amplifier A output - connects directly to load or feedback network; requires local decoupling near pin 4 (V+).
2	–IN A	Inverting input, channel A - sensitive node; guard ring and short trace routing minimize capacitive coupling.
3	+IN A	Noninverting input, channel A - referenced to system ground or bias voltage; matched impedance improves CMRR.
4	V+	Positive supply - must be decoupled with ≥0.1 µF ceramic capacitor to pin 11 (V−) or ground plane.
5	–IN B	Inverting input, channel B - electrically isolated from other channels; shares no internal substrate path with A/C/D.
6	+IN B	Noninverting input, channel B - identical DC and AC specs to +IN A; supports independent biasing per channel.
7	OUT B	Amplifier B output - routed separately from OUT A to prevent mutual inductance-induced crosstalk.
8	OUT C	Amplifier C output - pin-compatible with OUT A/B; enables symmetrical layout for 3-channel applications.
9	–IN C	Inverting input, channel C - same input stage topology as –IN A; validated for rail-to-rail common-mode operation.
10	+IN C	Noninverting input, channel C - supports DC-coupled sensor interfaces with <10 µV offset drift over temperature.
11	V−	Negative supply - tied to system ground in single-supply mode; serves as return path for all four amplifiers.
12	–IN D	Inverting input, channel D - fully independent; verified for −84 dB crosstalk at 5 MHz vs adjacent channels.
13	+IN D	Noninverting input, channel D - matches input capacitance (2 pF typical) and bias current (3 pA) of other inputs.
14	OUT D	Amplifier D output - completes quad configuration; supports simultaneous 4-channel video or data acquisition.

Key Features

Feature	Design Value
Rail-to-Rail Input/Output	Common-mode range extends 100 mV beyond V− and V+; output swings to within 100 mV of rails at 1 kΩ - maximizes dynamic range in 3.3-V or 5-V systems.
High Output Drive	±100 mA per channel continuous - eliminates need for external buffer stages when driving 75-Ω video lines or multiple ADC inputs.
Low Input Bias Current	3 pA typical - minimizes voltage error in high-impedance photodiode or pH sensor front-ends without guard traces.
Video-Optimized Performance	0.02% differential gain / 0.09° differential phase error into 150-Ω load - meets broadcast-grade NTSC requirements without external tuning.
Thermal Protection	Integrated shutdown at 160°C with hysteresis - prevents latch-up during transient overloads in sealed enclosures or high-density layouts.
Quad Channel Independence	Completely isolated circuitry per channel - measured −84 dB crosstalk at 5 MHz ensures signal integrity in RGB, XYZ, or multi-axis sensor systems.

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
OPA4350UA	Lower bandwidth (38 MHz), lower slew rate (20 V/µs), rail-to-rail input only (not output), higher quiescent current (1.8 mA/ch).	Better suited for precision DC-coupled applications than high-frequency video or fast-settling ADC buffering.	Select OPA4350UA only if bandwidth <40 MHz suffices and rail-to-rail output is not required.
LMH6629MQ	Higher bandwidth (1.5 GHz), higher slew rate (3000 V/µs), but non-rail-to-rail I/O, higher noise (1.9 nV/√Hz), and no thermal shutdown.	Targeted at RF and microwave signal chains where ultra-wideband gain is prioritized over DC accuracy or safety features.	Choose LMH6629MQ only for >500-MHz small-signal amplification where OPA4354AIPWR's 250-MHz limit is insufficient.

Compared with OPA4354AIPWR, OPA4350UA trades speed and rail-to-rail output for lower power and better DC precision, while LMH6629MQ sacrifices robustness and ease of use for extreme RF bandwidth - making OPA4354AIPWR the balanced choice for industrial video, medical imaging, and high-fidelity data acquisition.

FAQ

What is the maximum continuous output current per channel of the OPA4354AIPWR?

The OPA4354AIPWR delivers ±100 mA continuous output current per channel when operating from a 5-V supply, as specified in the Electrical Characteristics table under "IO Output current, single, dual, quad" with test condition VS = 5 V. This rating applies across the full −40°C to +125°C temperature range and supports direct driving of 75-Ω video cables or parallel-connected loads without external buffers. Exceeding this current continuously may trigger thermal shutdown at 160°C.

Does the OPA4354AIPWR support true rail-to-rail input and output operation?

Yes, the OPA4354AIPWR supports true rail-to-rail input and output operation. Its common-mode input voltage range extends 100 mV beyond both V− and V+, and its output swings to within 100 mV of each rail under 1-kΩ load conditions at 25°C - verified in Figure 20 and Figure 22 of the SBOS233G datasheet. This capability is maintained across the full −40°C to +125°C operating range, enabling full utilization of supply voltage headroom in low-voltage systems.

What is the channel-to-channel crosstalk specification for the OPA4354AIPWR?

The OPA4354AIPWR exhibits −84 dB channel-to-channel crosstalk at 5 MHz, as explicitly stated in the "OUTPUT" section of the Electrical Characteristics table. This value is measured between any two channels (e.g., A→B, A→C) and reflects the device's fully independent internal circuitry - a key differentiator from less isolated quad op amps. The specification holds across the full operating temperature range and validates suitability for RGB video routing and multi-sensor acquisition where signal purity is critical.

Can the OPA4354AIPWR operate from a 3.3-V single supply?

Yes, the OPA4354AIPWR is fully specified for operation from a 3.3-V single supply. Its recommended operating conditions list VS = 2.5 V to 5.5 V, and all key parameters - including 250-MHz unity-gain bandwidth, 150 V/µs slew rate, and rail-to-rail I/O - are guaranteed at 3.3 V. At this supply, output current capability reduces to ±50 mA (per the Electrical Characteristics table), and output swing remains within 100 mV of rails at 1-kΩ load, preserving dynamic range in modern low-voltage systems.

Is thermal shutdown implemented in the OPA4354AIPWR, and what are its thresholds?

Yes, the OPA4354AIPWR includes integrated thermal shutdown protection. It disables all four amplifiers when junction temperature reaches 160°C (shutdown threshold) and automatically resumes normal operation once the junction cools to 140°C (reset threshold), providing 20°C hysteresis. This feature is documented in the "THERMAL SHUTDOWN" section of the Electrical Characteristics table and protects against permanent damage during sustained overload or poor PCB thermal design - especially important in the 14-pin TSSOP package's constrained thermal profile.
