APX321WG-7

APX321WG-7 Description

The APX321WG-7 from Diodes Incorporated is a high-performance, general-purpose operational amplifier (op-amp) designed for precision analog applications. Packaged in a compact SOT-25 form factor and supplied in Tape & Reel (TR), this single-circuit op-amp operates over a wide supply voltage range of 2.5V to 5.5V, making it versatile for both low-voltage and standard 5V systems. With a 1 MHz gain bandwidth product (GBW) and a 1V/µs slew rate, it delivers stable performance for signal conditioning, filtering, and amplification tasks. Its ultra-low 15 nA input bias current and 1.7 mV input offset voltage ensure accuracy in sensitive measurements, while the 110µA supply current minimizes power consumption, ideal for battery-powered devices.

APX321WG-7 Features

• Low Power Consumption: Only 110µA supply current extends battery life in portable applications.
• Wide Supply Range: 2.5V to 5.5V operation supports diverse power architectures.
• High Precision: 15 nA input bias current and 1.7 mV offset voltage enhance signal integrity.
• Robust Output Drive: 90 mA output current capability for driving heavier loads.
• Compact & Reliable: SOT-25 package with MSL3 (168 hours) moisture sensitivity ensures durability in surface-mount designs.
• Compliance: ROHS3 and REACH compliant, meeting environmental and regulatory standards.

APX321WG-7 Applications

The APX321WG-7 excels in applications requiring precision, low power, and small footprint:

• Portable Electronics: Sensor interfaces, wearable devices, and IoT nodes benefit from its low current draw.
• Signal Conditioning: Active filters, integrators, and data acquisition systems leverage its stability and accuracy.
• Industrial Controls: Process monitoring, instrumentation, and feedback loops due to its wide voltage range.
• Consumer Electronics: Audio preamps, battery management, and low-noise amplification stages.

Conclusion of APX321WG-7

The APX321WG-7 stands out as a versatile, low-power op-amp with precision performance, making it an excellent choice for space-constrained and power-sensitive designs. Its combination of wide voltage range, low noise, and high output drive positions it above comparable general-purpose op-amps, particularly in portable and industrial applications. Diodes Incorporated’s commitment to quality ensures reliability, while compliance with ROHS3 and REACH underscores its suitability for modern eco-conscious designs.
