OP213ES

OP213ES Description

The OP213ES from Analog Devices Inc. is a high-performance, general-purpose dual operational amplifier (op-amp) housed in an 8-SOIC surface-mount package. Designed for precision applications, it operates over a wide supply voltage range of 4V to 36V, making it versatile for both low and high-voltage systems. With a low input offset voltage of 100 µV and input bias current of 240 nA, it ensures accuracy in signal conditioning and amplification. The 3.4 MHz gain bandwidth product (GBW) and 1.2V/µs slew rate enable stable performance in dynamic signal processing. Though marked obsolete, it remains a reliable choice for legacy designs requiring robust analog performance.

OP213ES Features

• Dual-channel design: Two independent op-amps in a single package, saving board space.
• Wide supply range (4V–36V): Suitable for battery-powered and industrial applications.
• Low noise and high precision: 100 µV offset voltage and 240 nA bias current for accurate signal processing.
• Moderate speed: 3.4 MHz GBW and 1.2V/µs slew rate balance power and performance.
• High output drive: 40 mA per channel for driving capacitive or resistive loads.
• Surface-mount (SOIC) packaging: Ideal for compact, automated assembly.
• MSL1 (Unlimited): No moisture sensitivity concerns during storage or handling.

OP213ES Applications

• Sensor signal conditioning: Ideal for amplifying low-level signals from thermocouples, strain gauges, or RTDs.
• Active filters and integrators: Stable performance in audio and instrumentation filtering.
• Power supply control: Voltage regulation and error amplification in DC-DC converters.
• Industrial automation: Process control, PLCs, and motor drive circuits requiring robust op-amps.
• Legacy system maintenance: Replacing older op-amps in obsolete equipment due to its compatibility.

Conclusion of OP213ES

The OP213ES is a versatile, precision dual op-amp offering a blend of wide voltage operation, low noise, and moderate bandwidth, making it suitable for diverse analog applications. While obsolete, its reliability and performance ensure continued use in legacy systems, sensor interfaces, and industrial controls. Engineers seeking a proven, general-purpose op-amp with low offset and high output drive will find it a practical solution despite newer alternatives.
