10BIT 30MSPS TRIPLE DAC
BW1221L_3CLK
GENERAL DESCRIPTION
The BW1221L_3CLK is a CMOS Triple
10Bit D/A converter for general &
video applications.
Its typical conversion rate is 30MSPS
(maximum 50MSPS) and supply voltage is
3.3V single. An external 1.0V voltage
reference(VREF) and a single resistor
(RSET) control the full_scale output current.
