1 Measured at IOUTA, driving a virtual ground, at 25
°C only.
2 Nominal full-scale current, IOUTFS, is 32× 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 = 175 MSPS and fOUT = 1.0 MHz, using differential clock.
5 Measured at fCLOCK = 100 MSPS and fOUT = 1.0 MHz, using differential clock.
6 ±5% power supply variation.
DYNAMIC SPECIFICATIONS (3.3 V)
TMIN to TMAX, AVDD = 3.3 V, DVDD = 3.3 V, CLKVDD = 3.3 V, IOUTFS = 2 mA, differential transformer coupled output,
453 Ω differentially terminated,1 unless otherwise noted.
