Audio ICs 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 audio compression ratio. 4) Built-in voltage regulator. FAbsolute maximum ratings (Ta = 25_C) FRecommended operating conditions (Ta = 25_C) ∗ VSC is a trademark of The Variable Speech Control Company.
