OPA357AIDDA Description

The OPA357AIDDA from Texas Instruments is a high-performance voltage feedback operational amplifier designed for precision applications requiring wide bandwidth and low power consumption. Packaged in an 8-SOPWRPAD (surface-mount) configuration, this IC operates over a 2.5V to 5.5V supply range, making it suitable for both single-supply and dual-supply systems. With a gain bandwidth product (GBWP) of 100 MHz and a slew rate of 150V/µs, it delivers exceptional signal fidelity for high-speed analog circuits. Despite its obsolete status, it remains a reliable choice for legacy designs due to its low input bias current (3 pA) and high output current drive (100 mA).

OPA357AIDDA Features

• Wide Supply Range: 2.5V–5.5V operation for flexible power configurations.
• High-Speed Performance: 100 MHz GBWP and 250 MHz -3dB bandwidth for fast signal processing.
• Low Power Consumption: 4.9mA supply current balances speed and efficiency.
• Precision Characteristics: 2mV input offset voltage and 3 pA input bias current ensure accuracy.
• Robust Output: 100 mA output current capability for driving heavy loads.
• Reliability: ROHS3 Compliant and REACH Unaffected, with MSL 1 (Unlimited) moisture sensitivity.
• Surface-Mount Design: 8-SOPWRPAD package optimizes PCB space and thermal performance.

OPA357AIDDA Applications

• High-Speed Data Acquisition: Ideal for ADC/DAC buffers due to low distortion and wide bandwidth.
• Active Filters: Suitable for RF and communication systems requiring fast settling times.
• Portable Electronics: Low power consumption benefits battery-operated devices.
• Test & Measurement Equipment: Precision and speed make it useful in oscilloscopes and signal analyzers.
• Video Amplification: High slew rate supports HD video signal conditioning.

Conclusion of OPA357AIDDA

The OPA357AIDDA excels in high-speed, precision analog applications, offering a blend of wide bandwidth, low noise, and efficient power use. While marked obsolete, its performance metrics—such as 150V/µs slew rate and 100 mA output drive—make it a strong candidate for legacy or niche designs. Engineers working on data converters, active filters, or portable instrumentation may find this amplifier particularly advantageous. Its surface-mount package and robust electrical characteristics ensure reliable integration into demanding systems.
