NOTES
1_{Measured at IOUTA, driving a virtual ground.}
2_{Nominal full-scale current, IOUTFS, is 32 × the IREF current.}
3_{Use an external buffer amplifier to drive any external load.}
4_{Reference bandwidth is a function of external cap at COMP1 pin and signal level.}
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 fCLOCK = 25 MSPS and fOUT = 1.0 MHz.}
7_{Measured as unbuffered voltage output with I OUTFS = 20 mA and 50 Ω RLOAD at IOUTA and IOUTB, fCLOCK = 100 MSPS and fOUT = 40 MHz.}
8_{± 5% Power supply variation.}
Specifications subject to change without notice.
