NCD2100 Digital Programmable Capacitors IXYS Integrated Circuits NCD2100 Digital Programmable Capacitors feature 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 via a simple two-wire serial bus. The NDC2100 series is designed to ensure proper operation of capacitive critical circuits by providing 1024 discrete capacitance values over a 6.6pF to 37.553pF nominal value range with step sizes of 0.063pF. IXYS Integrated Circuits NCD2100 Digital Programmable Capacitors are rated for operation with 2.4V to 5.5V supply voltages across a temperature range of -40″C to +85″C.
