DAC1233X
0.25µm 12-BIT 80MSPS DAC µ
GENERAL DESCRIPTION
The DAC1233X is a CMOS 12Bit D/A converter for general applications. Its maximum conversion rate is 80MSPS and supply voltage is 1.8V single. An external 0.7V voltage reference(VBIAS) and a single resister(RSET) control the full-scale output current .
FEATURES
-- 80MSPS pipeline operation -- 1.8V CMOS monolithic construction -- ± 0.6LSB differential linearity (typical) -- ± 1.5LSB integral 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

ABSOLUTE MAXIMUM RATINGS
Characteristics Supply Voltage Reference Input Voltage Operating Temperature Range Storage Temperature Range Symbol AVDD18D,AVDD18A Vin Topr Tstg Min -0.5 ~ +3.3 AVDD18D-0.2 to AVSS18D+0.2 0 to +70 -55 to +150 Unit V V °C °C
NOTES: 1. Absolute maximum rating values applied individually while another 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.
RECOMMENDED OPERATING CONDITIONS
Characteristics Operating Supply Voltage Digital Input Voltage High Digital Input Voltage Low Operating Temperature Range Output Load (effective) Reference Voltage Clock Cycle Time Clock Pulse Width High Clock Pulse Width Low IREF Current Symbol AVDD18A-AVSS18A AVDD18D-AVSS18D VIH VIL TOPR RL VREF Tclk Tpwh Tpwl Iref 1.6 0 12 6 6 50 0.5 700 0.2 70 V V °C V ns ns ns µA Min 1.5 Typ 1.8 Max 2.1 Unit V
NOTES: 1. It is strongly recommended that to avoid power latch-up all the supply pins(AVDD18A,AVDD18D) be driven from the same source. 2. Voltage on any digital pin that goes below AVSS18D (Digital Ground) by less than 0.2V can induce destructive latch-up.
