GENERAL DESCRIPTION

The ML2035 is a monolithic sinewave generator whose output is programmable from DC to 25kHz. No external

components are required. The frequency of the sinewave output is derived from either an external crystal or clock input, providing a stable and accurate frequency reference. The frequency is programmed by a 16-bit serial data word. The ML2035 has a VOUT amplitude of ±VCC/2.

FEATURES

■ Programmable output frequency - DC to 25kHz
