NOTES
1
Measured at IOUTA, driving a virtual ground.
2
Nominal full-scale current, I
OUTFS
, is 32
×
the I
REF
current.
3
Use an external buffer amplifier to drive any external load.
4
Reference bandwidth is a function of external cap at COMP1 pin.
5
For operation below 3 V, it is recommended that the output current be reduced to 12 mA or less to maintain optimum performance.
6
Measured at f
CLOCK
= 50 MSPS and f
OUT
= 1.0 MHz.
7
Measured as unbuffered voltage output into 50
