GENERAL DESCRIPTION

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.

FEATURES

■Programmable output frequency:

DC to 400kHz—using a crystal

DC to 500kHz—using an external digital clock

■3-wire SPI compatible serial interface with double buffered latch for programming the frequency

■Digital gain control for programming output amplitude

■SYNC input for synchronization of multiple sine waves

■Shutdown pin for sleep mode

■Single 5V power supply operation
