NOTES
1Measured at IOUTA, driving a virtual ground.
2Nominal full-scale current, IOUTFS, is 32 × the IREF current.
3Use an external buffer amplifier to drive any external load.
4Reference bandwidth is a function of external cap at COMP1 pin and signal level. Refer to Figure 41.
5For operation below 3 V, it is recommended that the output current be reduced to 12 mA or less to maintain optimum performance.
6Measured at fCLOCK = 50 MSPS and fOUT = 1.0 MHz.
7Measured as unbuffered voltage output into 50 Ω RLOAD at IOUTA and IOUTB, fCLOCK = 100 MSPS and fOUT = 40 MHz.
Specifications subject to change without notice.
