It is a single-function device in a 14-SOIC surface-mount package, intended for precision analog signal chains where a stable held value is needed during ADC conversion or multiplexer settling. The LF298MX comes in a 14-SOIC package with a body width of 3.90 mm (0.154\"), standard for SOIC-14 narrow. It is a surface-mount device, so the board footprint matches the usual SOIC-14 land pattern. No exposed pad or thermal slug — the package dissipates through the leads and the board copper. ## Lifecycle and compliance — active but RoHS non-compliant However, it is marked as RoHS non-compliant, which is a critical flag for any assembly line that must meet EU RoHS or similar restricted-substance requirements. This part uses lead-bearing solder terminations — verify your exemption or accept the non-compliant status before committing the BOM line.","metaTitle":"LF298MX Sample and Hold Circuit, 14-SOIC, Active","metaDescription":"LF298MX sample and hold IC in 14-SOIC surface mount package.
