Texas Instruments OPA354AIDBVRG4

Overview

OPA354AIDBVRG4 from Texas Instruments is a single-channel, rail-to-rail input/output CMOS operational amplifier optimized for high-speed video 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 drive, and operates from 2.5 V to 5.5 V supply - enabling use in RGB video line drivers, photodiode transimpedance amplifiers, and ADC/DAC interface circuits.

For engineers reviewing the OPA354AIDBVRG4 datasheet, OPA354AIDBVRG4 pinout, OPA354AIDBVRG4 application, or OPA354AIDBVRG4 equivalent, key selection criteria include its 100-mV rail-to-rail output swing at 1-kΩ load, thermal shutdown protection (160°C trip), −40°C to +125°C extended temperature rating, and compatibility with SOT-23-5 PCB layouts requiring minimal board space and high dynamic range.

Technical Context

The OPA354AIDBVRG4 employs a complementary CMOS input stage enabling rail-to-rail common-mode input range (extending 100 mV beyond supplies) and a Class AB output stage delivering true rail-to-rail output swing. Its voltage-feedback architecture supports unity-gain stability while maintaining 100-MHz gain-bandwidth product at G = +10.

It integrates on-chip thermal shutdown (160°C activation, 140°C recovery), supports single-supply operation down to 2.5 V, and features low 3 pA typical input bias current - making it suitable for high-impedance sensor interfaces and wide-dynamic-range video signal chains where DC accuracy and AC fidelity must coexist.

Key Specifications

Pinout & Package

FAQ

What is the maximum operating temperature range for the OPA354AIDBVRG4?

The OPA354AIDBVRG4 is specified over an extended industrial temperature range of −40°C to +125°C. Its thermal shutdown activates at 160°C junction temperature and resets at 140°C, providing reliable protection under sustained overload conditions. This makes OPA354AIDBVRG4 suitable for automotive cabin modules and industrial vision systems where ambient temperatures exceed standard commercial limits.

Does the OPA354AIDBVRG4 support single-supply operation below 3.3 V?

Yes, the OPA354AIDBVRG4 operates from 2.5 V to 5.5 V, enabling robust single-supply use at 2.7 V and 3.3 V. At 2.7 V, it maintains 110 V/µs slew rate and 200-MHz small-signal bandwidth, with rail-to-rail output swing preserved within 150 mV of both rails at 1-kΩ load - critical for portable medical and IoT sensor nodes powered by Li-ion or coin cells.

Can the OPA354AIDBVRG4 drive a 75-Ω video cable directly?

Yes, the OPA354AIDBVRG4 is explicitly characterized for 75-Ω back-terminated video loads, delivering 0.02% differential gain and 0.09° differential phase error per NTSC standards. When configured as a voltage follower with 75-Ω series output resistor and 75-Ω cable termination, it avoids capacitive loading instability and achieves 40-MHz 0.1-dB gain flatness - confirming direct usability in broadcast-quality RGB and composite video drivers.

Is the PowerPAD™ thermal pad on the OPA354AIDBVRG4 electrically active?

No, the PowerPAD™ on the OPA354AIDBVRG4 (SOT-23-5 DBV package) has no internal electrical connection and may be left floating or soldered to V− for improved thermal dissipation. TI documentation confirms it is thermally enhanced but electrically isolated - allowing designers to optimize PCB layout for either thermal performance or signal integrity without compromising grounding schemes.

How does the OPA354AIDBVRG4 handle input common-mode voltage beyond the supply rails?

The OPA354AIDBVRG4 features a complementary input stage that extends the common-mode range 100 mV beyond both V+ and V− rails. This is achieved via parallel N-channel and P-channel differential pairs, enabling valid operation with inputs as low as (V−) −0.1 V and as high as (V+) + 0.1 V - essential for interfacing with overvoltage-tolerant sensors or AC-coupled signals in single-supply systems without clamping diodes.
