NOTES
1Measured at IOUTA driving a virtual ground.
2Nominal full-scale current, IOUTFS, is 32
× the I
REF current.
3Use an external amplifier to drive any external load.
4For operation below 3 V, it is recommended that the output current be reduced to 12 mA or less to maintain optimum performance.
5Measured at f
CLOCK = 25 MSPS and fOUT = 1.01 MHz.
6Measured as unbuffered voltage output into 50
R
LOAD at IOUTA and IOUTB, fCLOCK = 32 MSPS and fOUT = 12.8 MHz.

Specifications subject to change without notice.
(TMIN to TMAX, AVDD = +5 V, PLLVDD = +5 V, DVDD = +5 V, IOUTFS = 20 mA, unless otherwise noted)
