NOTES

1Measured at IOUTA, driving a virtual ground.

2Nominal full-scale current, I

OUTFS, 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 f

CLOCK = 25 MSPS and fOUT = 1.0 MHz.

5Measured as unbuffered voltage output with I

OUTFS = 20 mA and 50 Ω RLOAD at IOUTA and IOUTB, fCLOCK = 100 MSPS and fOUT = 40 MHz.

6±5% Power supply variation.

Specifications subject to change without notice.

(TMIN to TMAX, AVDD = 3.3 V, DVDD = 3.3 V, IOUTFS = 20 mA, unless otherwise noted.)
