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 = 80 MSPS and fOUT = 1 MHz, using differential clock.
5 ±5% power supply variation, IOUTFS = 1 mA, at 25°C only.
DYNAMIC SPECIFICATIONS (1.8 V)
TMIN to TMAX, AVDD = 1.8 V, DVDD = 1.8 V, CLKVDD = 1.8 V, IOUTFS = 1 mA, differential transformer coupled output,
453 Ω differentially terminated,1 unless otherwise noted.
