GENERAL DESCRIPTION

The ML2036 is a monolithic sine wave generator whose output is programmable from DC to 50kHz. 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.

FEATURES

Programmable output frequency - DC to 50kHz

Low gain error and total harmonic distortion

3-wire SPI compatible serial microprocessor interface with double buffered data latch

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

Clock outputs of 1/2 or 1/8 of the input clock frequency

Synchronous or asynchronous data loading capability

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