NOTES

1Measured at IOUTA, driving a virtual ground.

2Nominal full-scale current, IOUTFS, is 32 times the IREF current.

3An external buffer amplifier with input bias current <100 nA should be used to drive any external load.

4Measured at fCLOCK = 25 MSPS and fOUT = 1.0 MHz.

5Measured at fCLOCK = 100 MSPS and fOUT = 1 MHz.

6Measured as unbuffered voltage output with IOUTFS = 20 mA and 50 Ω RLOAD at IOUTA and IOUTB, fCLOCK = 100 MSPS and fOUT = 40 MHz.

7± 10% Power supply variation.

Specifications subject to change without notice.
