Frequently Asked Questions
What is the input bias current of the OPA404SG?
The OPA404SG features an extremely low maximum input bias current (IIB) of 8 nA (0.000008 µA) at 25°C, and a maximum of 0.005 µA over the full operating range. This JFET-input characteristic makes it ideal for high-impedance sensor interfaces and precision instrumentation where leakage current must be minimized.
What applications is the OPA404SG designed for?
The OPA404SG is designed for precision instrumentation, medical equipment, active filters, data acquisition systems, and aerospace or defense applications. Its quad op-amp configuration, ultra-low bias current, high CMRR (100 dB typical), and ceramic package make it suitable for environments requiring high reliability and accurate signal conditioning.
What package does the OPA404SG use, and is it RoHS compliant?
The OPA404SG comes in a 14-pin Ceramic Dual-In-Line Package (14-CDIP), which is commonly used in military and high-reliability applications. The part is marked as Pb-free (RoHS compliant). The ceramic package provides excellent thermal stability and hermeticity compared to plastic packages.
How many amplifier circuits are in the OPA404SG?
The OPA404SG integrates 4 independent operational amplifier circuits (quad configuration) in a single 14-CDIP package. Each amplifier features JFET inputs with voltage-feedback architecture and integrated frequency compensation, allowing designers to implement multi-channel signal processing with fewer components.
