Texas Instruments OPA4354AIPWRG4

Overview

OPA4354AIPWRG4 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, and 6.5 nV/√Hz input voltage noise across all four independent amplifiers, supporting NTSC-compliant video buffering with 0.02% differential gain and 0.09° differential phase error.

For engineers reviewing the OPA4354AIPWRG4 datasheet, OPA4354AIPWRG4 pinout, OPA4354AIPWRG4 application, or OPA4354AIPWRG4 equivalent, key selection criteria include its 14-pin TSSOP package, ±100 mA output drive per channel, 2.5 V to 5.5 V single-supply operation, thermal shutdown protection at 160°C, and guaranteed performance over –40°C to +125°C.

Technical Context

The OPA4354AIPWRG4 employs a complementary CMOS input stage enabling rail-to-rail input common-mode range extending 100 mV beyond both supply rails, paired with a Class AB output stage delivering rail-to-rail swing within 100 mV of rails under 1-kΩ load. Its unity-gain stability and 100-MHz gain-bandwidth product support wideband closed-loop configurations without external compensation.

Each of the four fully isolated amplifier channels features independent biasing and thermal management, minimizing crosstalk (–84 dB at 5 MHz) and enabling simultaneous high-speed operation in multi-channel systems such as RGB video drivers, quad A/D converter input buffers, and active filter banks.

Key Specifications

Pinout & Package

OPA4354AIPWRG4 is packaged in a 14-pin TSSOP (PW) with body dimensions 5.00 mm × 4.40 mm and exposed pad thermally enhanced for PCB heat dissipation. PowerPAD™ is not present in this variant; thermal performance relies on standard copper pour under pins 11 (V−) and 4 (V+).

FAQ

What is the maximum continuous output current per channel for OPA4354AIPWRG4?

The OPA4354AIPWRG4 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 loads or parallel 150-Ω terminations without external current boosting. Exceeding ±100 mA continuously may trigger thermal shutdown.

Does OPA4354AIPWRG4 support true rail-to-rail input and output operation?

Yes, OPA4354AIPWRG4 supports true rail-to-rail input and output operation. Its input common-mode voltage range extends from (V−) −0.1 V to (V+) + 0.1 V, and its output swings to within 100 mV of both supply rails under 1-kΩ load conditions. This capability is enabled by a complementary CMOS input stage and Class AB output topology, allowing full utilization of 2.5-V to 5.5-V supply headroom in single-supply systems - a key enabler for low-voltage video and sensor interface designs.

What is the thermal shutdown threshold for OPA4354AIPWRG4?

The OPA4354AIPWRG4 incorporates an internal thermal shutdown circuit that activates at a junction temperature of 160°C and resets automatically when the junction cools to 140°C. This protection mechanism is documented in Section 7.7 of the SBOS233G datasheet under "THERMAL SHUTDOWN: JUNCTION TEMPERATURE." The feature prevents permanent damage during sustained overload or inadequate PCB thermal design, and is active across all four channels simultaneously.

Can OPA4354AIPWRG4 be used in single-supply 3.3-V applications?

Yes, OPA4354AIPWRG4 is fully specified for single-supply operation from 2.5 V to 5.5 V, including 3.3-V systems. At VS = 3.3 V, it maintains 110-V/µs slew rate (per datasheet Table 7.7), 250-MHz unity-gain bandwidth, and rail-to-rail I/O performance. Its input common-mode range extends to (V−) −0.1 V and (V+) + 0.1 V, enabling direct interfacing with 0–3.3-V sensor outputs or DACs without level-shifting circuitry - making OPA4354AIPWRG4 ideal for portable and battery-powered instrumentation.

What is the channel-to-channel crosstalk specification for OPA4354AIPWRG4?

The channel-to-channel crosstalk for OPA4354AIPWRG4 is –84 dB at 5 MHz, as measured and published in the Electrical Characteristics table under "OUTPUT" section of the SBOS233G datasheet. This value reflects worst-case coupling between any two channels (e.g., Channel A output affecting Channel B input) and confirms full functional isolation among all four amplifiers - essential for simultaneous multi-channel acquisition where signal integrity across channels must be preserved without external guarding or layout mitigation.
