NOTES
1Measured at IOUTA, driving a virtual ground.
2Nominal full-scale current, IOUTFS, is 32× the IREF current.
3An external buffer amplifier is recommended to drive any external load.
4100 MSPS fDAC with PLL on, fOUT = 1 MHz, all supplies = 3.0 V.
5300 MSPS fDAC.
6± 5% power supply variation.
Specifications subject to change without notice.
