MULTIPLIERS/DIVIDERS
One quadrant multiplierIf a particular multiplier circuit is designed to accept only polarity of input voltage on each of its inputs , then its operation will be limited to a single quadrant 。
Two quadrant multiplierOf a given multiplier circuit requires a single polarity on one input but accepts both polarities on the other 。
Four quadrant multiplierIf a multiplier is designed to accept either polarity on both of its inputs

SINGLE SUPPLY AMPLIFIERS
1. The output voltage can typically swing to within 1.0 volt of the +Vcc and to within 0.3 volt of the –Vcc level (ground in the case of single-supply operation).
2. The supply voltage can range between 3 and 44 volte .
3. Unity gain frequency is about 4.5 megahertz
4. Slew rates are as high as 13 volts per microsecond.
5.Full output voltage swings at frequencies over 100 kilohertz.

SINGLE SUPPLY AMPLIFIERS
1. The output voltage can typically swing to within 1.0 volt or less of +Vcc and ground.
2. The supply voltage can range between 5 and 18 volts.
3. Unity gain frequency is about 4 megahertz.
4. Slew rates are 0.5 volts per microsecond on the positive slope and 20 volts per microsecond on the negative slope.
5 Full output voltage swing up to about 8 kilohertz.
