NOTES
1Measured at IOUTA and QOUTA, driving a virtual ground.
2Nominal full-scale current, IOUTFS, is 16 the IREF current.
3Use an external amplifier to drive any external load.
4Measured at fCLOCK = 40 MSPS and fOUT = 1 MHz.
5Measured as unbuffered voltage output into 50 RLOAD at IOUTA, IOUTB, QOUTA, and QOUTB; fCLOCK = 40 MSPS and fOUT = 8 MHz.
Specifications subject to change without notice.
