NOTES
1Measured at IOUTA driving a virtual ground.
2Nominal full-scale current, IOUTFS, is 32ϫ the IREF current.
3Use an external amplifier to drive any external load.
4Measured at fDATA = 100 MSPS and fOUT = 1 MHz, DIV1, DIV0 = 0 V.
5Measured with PLL enabled at fDATA = 50 MSPS and fOUT = 1 MHz.
6Measured over a 3.0 V to 3.6 V range.
