VSC^∗ system processor IC
BA1701
The BA1701 is a monolithic audio-compression system controller IC that uses VSC^∗.
When used in combination with an analog delay circuit and low-pass filter, it can replay recorded audio at 1 to 2.5 times
the recording speed, without altering the pitch.
FApplications
Audio compression systems for tape-based answering machines and learning aids
FFeatures
1) Wide operating voltage range (4.5V to 14V).
2) Built-in two-phase sweep oscillator that can directly
drive BBD.
3) Built-in motor controller is synchronized with the au-
dio compression ratio.
4) Built-in voltage regulator.
FAbsolute maximum ratings (Ta = 25_C)
FRecommended operating conditions (Ta = 25_C)
