AD9837BCPZ-RL7, Цифровой генератор прямого синтеза, 2.3В до 5.5В, LFCSP-10

The AD9837BCPZ-RL7 is a Low Power Programmable Waveform Generator capable of producing sine, triangular and square wave outputs. Waveform generation is required in various types of sensing, actuation and time domain reflectometry (TDR) applications. The output frequency and phase are software programmable, allowing easy tuning. The frequency registers are 28 bits wide with a 16MHz clock rate, resolution of 0.06Hz can be achieved, with a 5MHz clock rate, the AD9837 can be tuned to 0.02Hz resolution. The AD9837 is written to via a 3-wire serial interface. This serial interface operates at clock rates up to 40MHz and is compatible with DSP and microcontroller standards. It has a power-down (sleep) function. Sections of the device that are not being used can be powered down to minimize the current consumption of the part.
