Procurement Notes

Verify the specific ordering suffix to confirm package type and qualification level. The RXB suffix indicates a 32-lead VQFN package. The T suffix denotes tape and reel packaging. The E suffix specifies an extended temperature range of -40°C to +125°C. The VAO suffix confirms AEC-Q100 automotive qualification. Ensure these parameters match the design requirements before procurement.

Selection Notes

Select this component for designs requiring a single-channel high-voltage operational amplifier with precise gain control. It is suitable for driving MEMS devices and laser beam steering systems. Consider the 32-lead VQFN package for automotive use or the 16-ball TFBGA for commercial applications. Verify that the required gain falls within the 30V/V to 90V/V range and that the load capacitance does not exceed 15 pF.
