NOTES
1
Measured at IOUTA, driving a virtual ground.
2
Nominal full-scale current, I
, is 32 times the I
current.
3
An external buffer amplifier with input bias current <100 nA should be used to drive any external load.
4
Measured at f
= 25 MSPS and f
= 1.0 MHz.
5
Measured as unbuffered voltage output with I
