DAC081S101 数据手册

MAXIMUM LOAD CAPACITANCE is the maximum capaci-

tance that can be driven by the DAC with output stability

maintained.

Specification Definitions

DIFFERENTIAL NON-LINEARITY (DNL) is the measure of

the maximum deviation from the ideal step size of 1 LSB,

which is V_REF/ 256 = V_A/ 256.

MONOTONICITY is the condition of being monotonic, where

the DAC has an output that never decreases when the

output code increases.

DIGITAL FEEDTHROUGH is a measure of the energy in-

jected into the analog output of the DAC from the digital

inputs when the DAC outputs are not updated. It is mea-

sured with a full-scale code change on the data bus.

MOST SIGNIFICANT BIT (MSB) is the bit that has the

largest value or weight of all bits in a word. Its value is 1/2 of

V_A.

FULL-SCALE ERROR is the difference between the actual

output voltage with a full scale code (FFh) loaded into the

DAC and the value of V_Ax 255 / 256.

POWER EFFICIENCY is the ratio of the output current to the

total supply current. The output current comes from the

power supply. The difference between the supply and output

currents, is the power consumed by the device without a

load.

GAIN ERROR is the deviation from the ideal slope of the

transfer function. It can be calculated from Zero and Full-

Scale Errors as GE = FSE - ZE, where GE is Gain error, FSE

is Full-Scale Error and ZE is Zero Error.

SETTLING TIME is the time for the output to settle within 1/2

LSB of the final value after the input code is updated.

GLITCH IMPULSE is the energy injected into the analog

output when the input code to the DAC register changes. It is

specified as the area of the glitch in nanovolt-seconds.

WAKE-UP TIME is the time for the output to settle to within

1/2 LSB of the final value after the device is commanded to

the active mode from any of the power down modes.

INTEGRAL NON-LINEARITY (INL) is a measure of the

deviation of each individual code from a straight line through

the input to output transfer function. The deviation of any

given code from this straight line is measured from the

center of that code value. The end point method is used. INL

for this product is specified over a limited range, per the

Electrical Tables.

ZERO CODE ERROR is the output error, or voltage, present

at the DAC output after a code of 00h has been entered.

LEAST SIGNIFICANT BIT (LSB) is the bit that has the

smallest value or weight of all bits in a word. This value is

LSB = V_REF/ 2ⁿ

where V_REFis the supply voltage for this product, and "n" is

the DAC resolution in bits, which is 8 for the DAC081S101.
