Texas Instruments OPA4354AIPWT

Overview

OPA4354AIPWT from Texas Instruments is a quad-channel, rail-to-rail input/output, 250-MHz unity-gain stable CMOS operational amplifier optimized for high-speed video, photodiode transimpedance, and analog-to-digital converter (ADC) input buffering. 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.

For engineers reviewing the OPA4354AIPWT datasheet, OPA4354AIPWT pinout, OPA4354AIPWT application, or OPA4354AIPWT equivalent, this page provides verified specifications, SOIC-14 and TSSOP-14 package details, channel-isolated performance data, thermal shutdown behavior, and validated alternative options for high-bandwidth signal conditioning in industrial imaging and optical networking systems.

Technical Context

The OPA4354AIPWT implements a complementary CMOS input stage enabling rail-to-rail common-mode input range extending 100 mV beyond both supply rails, with seamless transition between N- and P-channel pairs. Its class AB output stage supports rail-to-rail swing within 100 mV of rails at 1 kΩ load while sustaining ±100 mA continuous output current per amplifier.

Designed for unity-gain stability and wideband operation, it achieves 250 MHz small-signal bandwidth (G = +1), 100 MHz gain-bandwidth product (G = +10), and 40 MHz 0.1-dB gain flatness-enabling accurate reproduction of fast video edges and high-fidelity pulse signals without peaking or phase distortion.

FAQ

What is the maximum continuous output current per channel for OPA4354AIPWT?

The OPA4354AIPWT delivers ±100 mA continuous output current per channel at VS = 5 V, as specified in the Electrical Characteristics table under "IO Output current, single, dual, quad". This rating applies across the full –40°C to +125°C operating temperature range and supports direct drive of 75-Ω video cables and moderate-current laser diodes without external boost circuitry. Thermal shutdown activates at 160°C junction temperature to protect against sustained overload.

Does OPA4354AIPWT support true rail-to-rail input and output operation?

Yes, OPA4354AIPWT supports rail-to-rail input with common-mode voltage range extending 100 mV beyond both V– and V+, and rail-to-rail output with swing to within 100 mV of the supply rails at 1 kΩ load. This is achieved via complementary CMOS input pairs and a class AB output stage. At TA = 25°C and VS = 5 V, output voltage swing from rail is specified as 0.1 V (min) to 0.3 V (max), preserving full dynamic range in low-voltage 3.3 V systems.

What is the channel-to-channel crosstalk specification for OPA4354AIPWT?

The OPA4354AIPWT exhibits –84 dB channel-to-channel crosstalk at 5 MHz, as measured per the Electrical Characteristics table. This value reflects isolation between any two of its four independent amplifier channels and enables simultaneous processing of RGB, YUV, or multi-spectral signals without measurable interference - critical for high-fidelity imaging and broadcast video applications where inter-channel bleed would degrade color fidelity or spatial resolution.

Can OPA4354AIPWT operate from a 3.3 V single supply?

Yes, OPA4354AIPWT is fully specified for operation from 2.5 V to 5.5 V single supply (or ±1.25 V to ±2.75 V dual supply). At VS = 3.3 V, it maintains 110 V/µs slew rate (typical), 250 MHz unity-gain bandwidth, and rail-to-rail I/O functionality. Quiescent current remains 4.9 mA per channel, and output swing is within 100 mV of rails at 1 kΩ load - making it ideal for portable ultrasound, industrial cameras, and optical modules powered from standard 3.3 V LDOs.

Is thermal shutdown implemented in OPA4354AIPWT, and how does it behave?

Yes, OPA4354AIPWT includes an on-chip thermal shutdown circuit that activates at 160°C junction temperature and resets automatically when junction temperature falls below 140°C. This protection is documented in Section 7.7 under "Thermal Shutdown: Junction Temperature" and ensures reliability during sustained overload conditions - such as driving heavy capacitive loads or shorted outputs in compact optical assemblies where heatsinking is limited. Recovery is seamless and requires no external reset.
