The Intersil X90100 is a non-volatile electronically programmable capacitor. The device is programmed through a simple digital interface. After programming, the chosen setting for the device is retained by internal EEPROM storage whether or not DC power is maintained.

Features

• Non-volatile EEPROM storage of programmed trim codes

• Power On Recall of capacitance setting

• High-Performance Electronically Trimmable Capacitance

• Excellent linearity: <0.5 LSB error

• Very Simple Digital Interface

• Fast adjustments: 5µs max incremental change

• Eliminates the need for mechanical tuning

• Capacitance trimmable from 7.5pF to 14.5pF (singleended mode)

• Packages: - MSOP (1.1mm x 3.0mm x 3.0mm)

Applications

• Post-trim of low-cost regenerative receivers

• Tunable RF stages

• Low-cost, Low temperature drift oscillators

• Garage door openers

• Keyless entry
