1 Measured at IOUTA, driving a virtual ground.
2 Nominal full-scale current, IOUTFS, is 32 times the IREF current.
3 An external buffer amplifier with input bias current <100 nA should be used to drive any external load.
4 Measured at fCLK = 25 MSPS and fOUT = 1.0 MHz.
5 Measured at fCLK = 100 MSPS and fOUT = 1 MHz.
6 Measured as unbuffered voltage output with IOUTFS = 20 mA and RLOAD = 50 Ω at IOUTA and IOUTB, fCLK = 100 MSPS, and fOUT = 40 MHz.
7
10% power supply variation.
