zero-gate-voltage drain current (I_DSS)

The direct current into the drain terminal when the gate-source voltage is zero.

NOTE This is an on-state current in a depletion-type device, an off-state in an enhancement-type device.

zero scale (of an analog-to-digital converter [a digital-to-analog converter] with true zero)

A term used to refer a characteristic to the step whose nominal midstep [step] value equals zero.

NOTE 1 The subscript for the letter symbol of a characteristic at zero scale is "ZS".

NOTE 2 In place of a letter symbol, the abbreviation "ZS" is commonly used.

zero-scale error (of a linear analog-to-digital converter [digital-to-analog converter]) (E_ZS)

The difference between the actual midstep [step] value and the nominal midstep [step] value at specified zero scale.

NOTE Normally, this error specification is applied to converters that have no arrangement for an external adjustment of offset error and gain error.

zero scale, negative (of an analog-to-digital converter or digital-to-analog converter with no true zero)

A term used to refer a characteristic to the negative step closest to analog zero.

NOTE 1 The subscript for the letter symbol of a characteristic at negative zero scale is
"ZS-", e.g., V_ZS-_, I_ZS-.

NOTE 2 In place of a letter symbol, the abbreviation "ZS-" is commonly used.

zero scale, positive (of an analog-to-digital converter or digital-to-analog converter with no true zero)

A term used to refer a characteristic to the positive step closest to analog zero.

NOTE 1 The subscript for the letter symbol of a characteristic at positive zero scale is "ZS+", e.g., V_ZS+, I_ZS+.

NOTE 2 In place of a letter symbol, the abbreviation "ZS+" is commonly used.
