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 fCLOCK = 100 MSPS and fOUT = 1 MHz.
5
Measured as unbuffered voltage output with IOUTFS = 20 mA, 50 RLOAD at IOUTA and IOUTB, fCLOCK = 100 MSPS, and fOUT = 40 MHz.
6
±5% power supply variation.
