Texas Instruments OPA356AIDBVT

Overview

OPA356AIDBVT from Texas Instruments is a single-channel, high-speed, voltage-feedback CMOS operational amplifier optimized for video signal conditioning and wideband analog applications. It delivers 450MHz unity-gain bandwidth, 360V/µs slew rate, rail-to-rail output swing within 100mV of rails, and differential gain/phase error of 0.02%/0.05° - enabling precision NTSC video amplification in compact SOT23-5 packaging.

For engineers reviewing the OPA356AIDBVT datasheet, OPA356AIDBVT pinout, OPA356AIDBVT application, or OPA356AIDBVT equivalent, key selection criteria include its 200MHz gain-bandwidth product, ±60mA continuous output drive into 150Ω, –40°C to +125°C extended temperature rating, low 5.8nV/√Hz input voltage noise, and ground-sensing input common-mode range down to V– – 0.1V.

Technical Context

The OPA356AIDBVT employs a fully differential CMOS input stage with 3pA typical input bias current and 10¹³ Ω || 1.5pF input impedance, supporting DC-coupled single-supply operation from 2.5V to 5.5V. Its internal thermal shutdown activates at 160°C junction temperature and resets at 140°C, ensuring robustness during overload conditions.

It achieves 0.1dB gain flatness to 75MHz with 150Ω load and maintains <–81dBc 2nd-harmonic distortion at 1MHz with 2Vpp output - critical for high-fidelity video buffering, photodiode transimpedance amplification, and ADC/DAC interface circuits requiring minimal signal degradation.

FAQ

What is the maximum continuous output current specification for OPA356AIDBVT?

The OPA356AIDBVT supports ±60mA continuous output current into resistive loads, as specified in the Electrical Characteristics table under "Output Current, Continuous" at TA = –40°C to +125°C. Exceeding this limit risks thermal shutdown activation or long-term reliability degradation, though peak currents up to ±100mA are permitted briefly at VS = +5V.

Does OPA356AIDBVT support true single-supply operation with input signals referenced to ground?

Yes, the OPA356AIDBVT features an input common-mode voltage range extending 100mV below ground (V– – 0.1V) and up to 1.5V below V+, enabling direct connection of ground-referenced sources such as DAC outputs or sensor bridges without level-shifting circuitry - a core design feature confirmed in the Applications Information section.

What is the recommended bypass capacitor configuration for OPA356AIDBVT on a 5V supply?

Texas Instruments specifies a minimum 10µF ceramic bypass capacitor at the V+ pin, with optional parallel addition of a ≥1µF tantalum capacitor when driving low-resistance loads (e.g., 150Ω video cables). This dual-capacitor approach suppresses high-frequency supply noise and improves harmonic distortion performance, as detailed in the PCB Layout section of the SBOS212A datasheet.

How does thermal shutdown operate in OPA356AIDBVT, and what are the trip/reset thresholds?

The OPA356AIDBVT incorporates an on-chip thermal shutdown circuit that disables the amplifier output when junction temperature reaches 160°C, and automatically resumes normal operation once the junction cools to 140°C. This hysteresis prevents oscillatory cycling and is validated across the full –40°C to +125°C operating range per the Absolute Maximum Ratings and Typical Characteristics sections.

Is OPA356AIDBVT pin-compatible with other members of the OPAx356 family in SOT23-5 packaging?

Yes, all SOT23-5 variants of the OPAx356 family - including OPA356AIDBVT, OPA356AIDBVR, and OPA356AIDBVRG4 - share identical pinout, package dimensions, and thermal characteristics. The suffix differences denote tape-and-reel quantity (250 vs 3000) and RoHS compliance status, but electrical and mechanical compatibility is maintained across these orderable variants.
