NOP912/NOP914 Operational Amplifiers for Precision Circuits and High-Speed Applications

We all know that operational amplifiers (OP Amps) have various functions, including addition, subtraction, integration, differentiation, and comparison, as well as signal and differential amplification of small signals. These functions are crucial components in analog signal processing and are widely used in various fields such as home appliances, industrial applications, and more.

In Nuvoton Technology's NOP912/NOP914 series, the NOP912 offers Dual channels, while the NOP914 provides Quad channels, giving designers more options to meet various design requirements.

This series features 5V operational amplifiers with low offset voltage and wide gain bandwidth, making them ideal for precise small-signal and high-speed signal applications, such as voltage and current sampling or sensor applications in industrial control.

The NOP912/NOP914 series adopts a chopper-stabilized architecture, which minimizes internal component errors to improve output precision. As a result, the offset voltage can be as low as 50 µV, and the temperature drift is as low as 0.05 µV/°C. This makes them suitable for industrial environments, with the entire series meeting the industrial-grade operating temperature range of -40°C to 105°C.

Additionally, the NOP912/NOP914 series offers several features that make circuit design easier for users:

• Wide gain bandwidth of up to 8 MHz, providing more bandwidth for gain amplification.
• Rail-to-rail input/output, allowing signals to approach the full range of the positive and negative supply voltages, facilitating circuit design.
• High slew rate of 6V/µs, helping to reduce distortion and enhance precision.
• Direct replacement: NOP912 (dual-channel) comes in SOIC-8 packaging, and NOP914 (quad-channel) comes in TSSOP-14 packaging. These are fully compatible with the same packaging used by most brands on the market. allowing users to directly replace them pin-to-pin, saving cost.
