NCD2100

NON-VOLATILE DIGITAL PROGRAMMABLE CAPACITOR

 The NCD2100 is an EEPROM based digitally programmable variable capacitor that provides capacitive offset trimming for capacitance sensitive circuits.

 

Programming the non-volatile EEPROM register value or implementing on demand capacitance value changes are easily accomplished by means of the simple two-wire serial bus.

 

NCD2100 Features include:

• Very small packages: 2mm x 2mm DFN package and 2.8mm x 2.9mm TSOT package

• Wide nominal capacitance range: 6.6pF to 37.553pF

• Smallest switchable capacitor: 0.063pF

• Minimal nominal current draw: IDD=1µA

• Wide operating temperature range: -40°C to +85°C

 

USED FOR:

 

• VCXOs

• Crystal Oscillators

• Tunable RF Stages

• Filter Tuning

• RFID Tags

• Industrial Wireless Control

• Capacitor Sensor Trimming
