Data Sheet

TERMINOLOGY

Integral Nonlinearity

Gain Error

Integral nonlinearity is the maximum deviation from a straight

line passing through the endpoints of the ADC transfer function.

The endpoints of the transfer function are zero scale, a point 1 LSB

below the first code transition, and full scale, a point 1 LSB

above the last code transition.

Gain error is the deviation of the last code transition (111…110)

to (111…111) from the ideal (that is, V_REF– 1 LSB) after the

offset error is adjusted out.

Track-and-Hold Acquisition Time

The track-and-hold amplifier enters the acquisition phase on

the fifth falling edge of DCLK after the start bit has been

detected. Three DCLK cycles are allowed for the track-and-hold

acquisition time. The input signal is fully acquired to the 12-bit

level within this time even with the maximum specified DCLK

frequency. See the Analog Input section for more details.

Differential Nonlinearity

Differential nonlinearity is the difference between the measured

and the ideal 1 LSB change between any two adjacent codes in

the ADC.

Offset Error

Offset error is the deviation of the first code transition (00…000)

On Resistance

to (00…001) from the ideal, that is, AGND + 1 LSB.

On resistance is a measure of the ohmic resistance between the

drain and source of the switch drivers.
