ML2037

The ML2037 is a precision programmable sine wave generator with a frequency range of DC to 500kHz. The device is capable of generating a wide frequency range of low distortion sine waves with no external passive components. The frequency of the sine wave output is programmed by a 16-bit word that is loaded through a serial input. The sine wave output frequency of ML2037 is determined by the programmed value and the clock frequency. The clock frequency is derived from either an external crystal connected to the device or an external clock input to provide a stable and accurate frequency reference.

The sine wave output of the ML2037 is filtered and has a programmable amplitude that is digitally programmed in 0.5V steps. The maximum amplitude is 2.0VP-P centered at a 2.5V level. The device functions from a single 5V power supply and has a shutdown pin to put the device into a low power mode that disables the output. A sync input of ML2037 is provided to allow the synchronization of more than one device in a system.
