10BIT 80MSPS DAC

FUNCTIONAL DESCRIPTION

AL1214H

This is

a 10bit 80MSPS digital to analog data

Linearity Error : Linearity error is defined as the

maximum deviation of the actual analog output from

the ideal output, determined by a straight line drawn

from zero to full scale.

converter and uses segment architecture for 5bits of

MSB sides and binary-weighted architecture for 5bits

of LSB side. It contains of 1'st latch block, decoder

block, 2nd latch block, AMP block, CM (current

mirror ) block and analog switch block. This core

uses reference current to decide the 1LSB current size

by dividing the reference current by 116 times. So the

reference current must be constant and the switch's

physical real size can be constant by using AMP

block with high DC gain. The most significant block

of this core is analog switch block and it must

maintain the uniformity at each switch, so layout

designer must care of the matching characteristics on

analog switch and CM block. And more than 80%

of supply current is dissipated at analog switch block

and AMP block. And it uses samsung(SEC) standard

cell as all digital cell of latch , decoder and buffer.

And to adjust full current output, you must decide the

"Rset" resistor value(connected to IREF pin) .Its

voltage output can be obtained by connecting Rload

(connected to IO pin) .

Monotonicity

A D/A converter is monotonic if

the output either increases or remains constants as

the digital input increases.

Offset Error : The deviation of the output current

from the ideal of zero is called offset error. For IO ,

0mV output expected when the inputs are all 0s.

Gain Errors

The difference between the actual

andideal output span. The actual span is determined

by the output when all inputs are set to 1s minus the

output when all inputs are set to 0s.

Output Compliance Range : The range of allowable

voltage at the output of a current-output DAC.

Operation beyond the maximum compliance limits may

cause either output stage saturation or breakdown

resulting in nonlinear performance.

Settling Time : The time required for the output to

reach and remain within a specified error band about

its final value, measured from the start of the output

transition

Glitch Impulse : Asymmetrical switching times in a

DAC give rise to undesired output transients that are

quantified by a glitch impulse. It is specified as the

net area of the glitch in pV-s
