Fingerprint biometric systems use a persons unique fingerprint to offer a higher level of security for protecting data, homes or offices from intrusions. Fingerprint systems provide more convenient access than keys or combination locks. These systems increasingly are being used for PC and notebook access, remote network management, room entry, data-storage devices, safe deposit boxes, and many other applications where security is critical. National offers a variety of interface and power management products used in fingerprint biometrics systems.

Component Highlights

* Low-dropout regulators - provides a highly efficient solution to supply low-ripple, precise voltages to processors and DSP devices.

* ADC - select from several high-speed 10- and 12-bit converters, many offering digital error correction and on-chip sample-and-hold circuits to minimize power consumption.
