SY21283 Datasheet
SY21283 Price Notes l. When Di to prevent breakdown in case of reverse connection is used, it is necessary to insert a capacitor Cr to secure the regenerative current route. Similarly, Cr is necessary to enhance the reliability when there is no capacitor near the fan power line. 2. To obtain Hall bias from Vcc, carry out l/2 x VCC bias as shown in the figure. Linear driving is made through voltage control of the coil by amplifying the Hall output. When the Hall element output is large, the startup performance and efficiency are improved. Adjustment of the Hall element can reduce the noise further. 3. When the Hall bias is taken from the HB pin, constant-voltage bias is made with about 2.0 V. Therefore, the Hall element can provide the output satisfactory in temperature characteristics. Adjustment of the Hall output amplitude is made with Rl. (When Vcc = 12 V, the step *2 above proves advantageous for lC heat generation.) 4. Keep this open when not used. 5. When the wiring from the Hall output to lC Hall input is long, noise may be carried through the wiring. In this case, insert the capacitor as shown in the figure.

This very high speed family uses new DMC proprietary circuitry to extend 12 bit data conversion rates beyond 0.58MHz ... and 8 bit data conversion rates beyond l.5MHz ... to open up new applications and to upgrade many exlstlng slots. These converters are designed and characterized for use in high speed data acquisItion systems, fast Fourier transform analysls, radar pulse analysis, scan- ning medical instrumentation and similar applIcations requiring fast conversion rates, good linearity and ex cellent stability ... or where many Inputs must be digitized in a very short period of time. These are successive approxlmatlon designs. Internal - 10V references are available In the serIes, as well as capability for an external reference between - 9V and - 11V. PrecisIon metalm technology Is employed for ultra-stable operation. |
