MV5089
DTMF GENERATOR
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.
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
astaircase approximation of a sinewave with low total distortion.
Frequency and amplitude stability over operating voltage
and temperature range are maintained within industry
specifications.
