BUCKET-BRIGATE ANALOG DELAY LINE, NOS, DIP ICs New old stock DIPs (NOS ICs). Why they no longer make this legendary and extremely useful IC (and the SAD 1024) is a mystery to me! The SAD 512 is getting very hard to find these days. Note, this is an ANALOG DELAY LINE IC - it is NOT a digital delay line IC, which are relatively a dime a dozen. Great for generating audio special effects, such as echos, reverberations and sum-and-difference frequences / comb filter / flanger / phaser effects, to give music and sounds more depth, character, uniqueness and richness, and for special audio effects / audio special effects. Other applications include voice control of tape recorders to prevent loss of initial sounds (real time voice triggers the recorder's ON/OFF control while also being recorded by the SAD512 circuitry; then after tape recorder starts recording, the delayed sound from the last SAD512 stage output comes through and you miss nothing), variable signal control of amplitude or of equalization filters, tremolo, vibrato and chorus effects in electronic musical instruments, variable or fixed delay of analog signals, time compression of recorder and telephone conversations or other analog signals (for example, to minimize dead periods that only waste listening time), music and audio sampling systems, and for the ever-popular voice scrambling and voice encoding systems. SAD512 ICs can be cascaded together to increase delays and to tap off of intermediate points to increase delay or resolution. Clock rate may be as high as 1.5MHz. Input signal frequency can be more than 200KHz, so the SAD512's usefulness extends well into the ultrasound (ultrasonic) / sonar bands, and handles treble frequencies nicely. Much easier, faster, cheaper and compact to implement than ADC-to-DAC digital methods, and some audiophiles say that the results are much more natural-sounding than digitized music. Superior to the TDA1022 (also a 512-stage bucket-brigade analog delay line) because the TDA 1022 requires a negative power supply and is good for input signals only up to 45 KHz - I won't design with a TDA1022 for any of my ultrasonic, sonar and treble frequency bandwidth special projects. The SAD512 is simply a fantastic IC! I recently purchased a ton of these - more than I can use in a lifetime, so I am selling off a small percentage of my stock. Do you need SAD1024 ICs? If you can't expand the space or wiring on your circuit board to accommodate two SAD512 ICs, and you have the physical room on your PC board to stack two SAD512 ICs, with a little wiring finagling you can relatively easily wire in two SAD512 ICs to do the function of one SAD 1024. The SAD1024 ICs we have we are not selling. NOTE: Later availability not guaranteed. LIMITED QUANTITY. Seller listing codes: LD061, LR096-S01, LR099-S01, LS000-R00, MM000, CC000.
