AL1214A
12-BIT 160MSPS DAC
1
GENERAL DESCRIPTION
The AL1214A is a CMOS 12-bit D/A converter for general applications. Its maximum conversion rate is 160MSPS
and supply voltage is 5V single. An external 3.2V voltage reference (VBIAS) and a single resister (RSET) control
the full-scale output current .
FEATURES
160MSPS pipeline operation
5V CMOS monolithic construction
0.3LSB differential linearity (typical)
1.5LSB internal linearity (typical)
External voltage reference
12-bit voltage parallel input
TYPICAL APPLICATIONS
High Definition Television (HDTV)
Hard Disk Drive
High Resolution Color Graphics
CAE/CAD/CAM
ATE (Auto Test Equipment)

NOTES:
1.
Absolute maximum rating values applied individually while allother parameters are within specified operating condition.
Function operation under any of these conditions is not implied.
2.
Applied voltage must be current limited to specified range
3.
Absolute maximum ratings are value beyond which the device may be damaged permanently. Normal operation is not
guaranteed.

NOTES:
1.
It is strongly recommended that to avoid power latch-up all the supply pins(VDDA,VDDD) be driven from the same
source.
2.
Voltage on any digital pin that goes below VSSD (Digital Ground) by less than 0.3V can induce destructive latch-up
