Maxim has introduced its first electronically programmable capacitor with high self-resonant frequency and 32 discrete capacitive steps. Housed in an SC70 package (2,2 x 2,4 mm), the MAX1474 is designed to replace mechanical inductors in common tuning circuits. It can be set to any one of 32 discrete capacitive steps ranging from 6,26 to 12,74 pF in 0,2 pF increments.
Application circuits can be used to increase the capacitive range, increase capacitive steps, or to multiply the Q-value to fit a particular application. Maxim says that because the capacitors are actually implemented in silicon, there is virtually no drift over time (less than 33 ppm/°C) A Q of 50 is possible.
Two pins are used to program the MAX1474. Capacitive values are selected by raising the enable pin and sending the device a discrete number of pulses corresponding to the desired capacitive value. It does not require a clock and will retain the programmed capacitance value for as long as power is supplied. If the system is dynamic and has the ability to retune itself, the capacitance value can easily be changed at any time by simply raising the enable pin and sending the desired number of pulses.
Applications include post-trim of low-cost regenerative stages, tuneable RF stages, garage door openers, keyless entry, industrial wireless control, and precision trimming of capacitive-based sensors.
