Description

The MV5089 is fabricated using ISO-CMOS high density technology and offers low power and wide voltage operation. An inexpensive 3.58MHz TV crystal completes the reference oscillator. From this frequency are derived 8 different sinusoidal frequencies which, when appropriately mixed, provide Dual-Tone Multi-Frequency (DTMF) tones.

MV5089 Inputs are compatible with a standard 2-of-8 active-low keyboard and the keyboard entries determine the correct division of the reference frequency by the row and column counters.

D-to-A conversion, using R-2R ladder networks, results in a staircase approximation of a sinewave with low total distortion.

Frequency and amplitude stability over operating voltage and temperature range are maintained within industry specifications.
