2.0 Applications Information

(Continued)

The sample-and-hold error specifications are included in the

error and timing specifications of the A/D. The hold step and

gain error sample/hold specs are included in the ADC10154/

ADC10158’s total unadjusted, linearity, gain and offset error

specifications, while the hold settling time is included in the

A/D’s maximum conversion time specification. The hold

droop rate can be thought of as being zero since an unlim-

ited amount of time can pass between a conversion and the

reading of data. The data is lost after a new conversion has

been completed.

Protecting the Analog Inputs

DS011225-25

Diodes are 1N914.

The protection diodes should be able to withstand the output current of the op amp under current limit.
