APEM recommends a 4-layer PCB with a solid ground plane, and to keep the input and output traces as short as possible to minimize noise and EMI. Additionally, it's recommended to use a common mode choke or ferrite bead on the input lines to filter out high-frequency noise.
The IPR3SAD2LOG has built-in overvoltage protection (OVP) that can withstand up to 40V for a short duration. However, it's recommended to use an external TVS diode or voltage clamp to protect the device from sustained overvoltage conditions.
The IPR3SAD2LOG is rated for operation from -40°C to 125°C, but the device's accuracy and linearity may degrade at extreme temperatures. It's recommended to derate the device's performance at temperatures above 85°C.
Yes, the IPR3SAD2LOG is designed to meet the requirements of high-reliability and safety-critical applications, such as aerospace, defense, and medical devices. However, it's recommended to consult with APEM's application engineers to ensure the device meets the specific requirements of the application.
APEM recommends a two-point calibration procedure to ensure optimal accuracy and linearity. The procedure involves applying a known input voltage and adjusting the device's output to match the expected value, and then repeating the process at a second input voltage point.
