NCD2100
Non-volatile
Digital Programmable Capacitor
Description
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.
Providing 1024 discrete capacitance values over a
nominal value range of 6.6pF to 37.553pF with step
sizes of 0.063pF, the NCD2100 is well suited to ensure
proper operation of capacitive critical circuits.
Additionally, to ensure interoperability over a broad
array of design environments, the NCD2100 is rated
for operation with supply voltages of 2.5V to 5.5V
across the temperature range of -40C to +85C.
