Description:The VRE410 is a low cost, high precision, ±10V reference. Recommended for D/A and A/D converters which require and external precision reference. The device provides ultra-stable ±10V output with ±1.6mV initial accuracy and a temperature coefficient of 1.0 ppm/°C. This improvement in accuracy is made possible by a unique, patented multipoint laser compensation technique. Another key feature of this reference is the 3mV tracking error between the positive and negative output voltages over the full operating t
Apex Microtechnology recommends a 4-layer PCB with a solid ground plane, and thermal vias under the device to dissipate heat. A thermal pad on the bottom of the package should be connected to a heat sink or a thermal management system.
Apex Microtechnology recommends following the recommended biasing and configuration guidelines in the datasheet, and using the evaluation board as a reference design. Additionally, consult the application notes and technical support resources provided by Apex Microtechnology.
The VRE410JS is rated for operation up to 125°C, but thermal derating is required above 85°C. Ensure proper thermal management, and consider reducing the output current or using a heat sink to maintain a safe junction temperature.
Use a combination of visual inspection, signal probing, and simulation tools to identify the root cause of the issue. Consult the datasheet, application notes, and technical support resources provided by Apex Microtechnology for guidance on troubleshooting and debugging.
Follow proper PCB layout and design practices to minimize EMI and RFI. Ensure the device is properly shielded, and use filtering and shielding components as necessary. Consult the datasheet and regulatory standards (e.g., FCC, CE, etc.) for specific requirements and guidelines.
