NOTES
1Measured at I
OUTA, driving a virtual ground.
2Nominal full-scale current, I
OUTFS, is 32 × the I REF current.
3Use an external buffer amplifier to drive any external load.
4Reference bandwidth is a function of external cap at COMP1 pin and signal level.
5For operation below 3 V, it is recommended that the output current be reduced to 12 mA or less to maintain optimum performance.
6Measured at f
CLOCK = 25 MSPS and fOUT = 1.0 MHz.
7Measured as unbuffered voltage output with I
OUTFS = 20 mA and 50 RLOAD at IOUTA and IOUTB, fCLOCK = 100 MSPS and fOUT = 40 MHz.
8
± 5% Power supply variation.
Specifications subject to change without notice.
(TMIN to TMAX , AVDD = +5 V, DVDD = +5 V, IOUTFS = 20 mA, unless otherwise noted)
