Address, Timing and Waveforms
NOTES:
3. The Idle address is protective in that SB_H input noise cannot disturb the chip if the Idle address is selected; also, the Address inputs are High
4. Address Numbers 9 - 11 are shaded to indicate test mode conditions and are shown for information only. These addresses are used in original
5. Digital Programming: To set the digital addresses, only the proper digital address and a negative pulse >100ns on SB_H is needed. To reset the
6. Analog Programming: To program the eight S/H circuits, addresses of 0-5V analog signal on V

digital addresses to the default states, Address 15 and a SB_H pulse >100ns is needed. Normally the digital addresses will be set first, and the
analog addresses programmed next. The test modes, Address Numbers 9 - 11, will normally only be used during factory testing. An address
15 Reset should normally precede most programming in order to assure that the digital address states begin in their default state. Otherwise,
the digital address states will be undefined because there is no power-up-reset.
(20 s) pins are needed. The NullB pulse is valid only during the SB_H pulse and should occur during the first half of the SB_H pulse. The S/H
amplifier is auto-zeroed for zero offset when both NullB and SB_H are low. The input V
