Frequently Asked Questions
What is the supply voltage range for the OPA2340UA?
The OPA2340UA operates from a single supply voltage, designed for rail-to-rail input and output performance. It is optimized for single-supply systems typically in the 2.5V to 5.5V range, making it suitable for battery-powered and low-voltage portable applications.
What is the input bias current of the OPA2340UA?
The OPA2340UA features an exceptionally low input bias current of 0.00001µA (10pA) maximum at 25°C, with a maximum of 0.00006µA over the full temperature range. This makes it ideal for high-impedance source applications such as photodiode amplifiers and pH meters.
What package is the OPA2340UA available in?
The OPA2340UA is available in a Small Outline Package (SOIC/SOP), which is a standard surface-mount package offering a good balance of compact size and ease of PCB assembly. It is suitable for automated soldering processes in production environments.
What are typical applications for the OPA2340UA?
The OPA2340UA is commonly used in portable medical instruments, industrial sensor signal conditioning, photodiode transimpedance amplifiers, active filters, and data acquisition front-ends. Its rail-to-rail operation and low bias current make it especially effective in precision, low-power designs.
Is the OPA2340UA a single or dual op-amp?
The OPA2340UA is a dual operational amplifier, containing two independent op-amp channels in a single package. This dual configuration reduces component count and board space compared to using two separate single op-amp devices, while maintaining the same high performance per channel.
