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 ML2004 logarithmic gain/attenuator
