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

■ Fully integrated solution - no external components required

■ Frequency resolution of 1.5Hz (±0.75Hz) with a 12MHz clock input

■ Onboard 3 to 12MHz crystal oscillator

■ Synchronous or asynchronous data loading capability

■ Compatible with ML2031 and ML2032 tone detectors and ML2004 logarithmic gain/attenuator
