1 Measured at IOUTA, driving a virtual ground.
2 Normal full scale current, IOUTFS is 32 × the IREF current.
3 Use an external buffer amplifier with an input bias current <100 nA to drive any external load.
4 Measured at fCLOCK = 175 MSPS and fOUT = 1.0 MHz, using a differential clock.
5 Measured at fCLOCK = 100 MSPS and fOUT = 1.0 MHz, using a 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 unless otherwise noted.
