onsemi NCx21871, NCx21872, & NCx21874 Zero-Drift Op Amps

onsemi NCx21871, NCx21872, and NCx21874 Zero-Drift Operational Amplifiers (Op Amps) feature offset voltage as low as 45μV over the 1.8V to 5.5V supply voltage range. The zero-drift architecture reduces the offset drift to as low as 0.4μV/°C and enables high-precision measurements over time and temperature. onsemi NCx21871, NCx21872, and NCx2187 Op Amps have low power consumption over a wide dynamic range and are available in space-saving packages. These features make these devices well-suited for signal conditioning circuits in portable, industrial, automotive, medical, and consumer applications.    

Variants with the NCV prefix are AEC-Q100 qualified and PPAP capable, making them ideal for automotive and other applications requiring unique site and control change requirements.
