AF1502

AF150 : The AF 150 wide band active filter is a general second order lumped RC network. Only four external resistors are required to program the AF 150 for specific second order functions. Low pass, high pass and band pass functions are available simultaneously at separate outputs. Notch and all pass functions can be formed by summing the outputs with an external amplifier. Higher order filters are realized by cascading AF 150 active filters with appropriate programming resistors. Any of the classical filter configurations, such as Butterworth, Bessel, Cauer and Chebyshev can be formed. Features • Independent Q, frequency, gain adjustments • Low serisitivity to external component variation • Sep.

AF1502A : AF1502A is a step down LED driver that is designed to meet maximum 2A constant current for high power LED application, and utilizes PWM control scheme that switches with 300Khz fixed frequency. The input voltage range of AF1502A is from 4.2V to 23V. It is suitable for series-parallel 1W, 3W, or 5W high power LED application due to the high operation voltage and output capability.
