Suitable for use in handheld portable electronic equipment, the products' features include chopper-stabilized, high-sensitivity thresholds, high temperature stability, low switch-point drift, and insensitivity to physical stresses.

All three devices are offered in a single-inline package and SOT23W surface-mount package.
