MAX5890

14-Bit, 600Msps, High-Dynamic-Performance

DAC with LVDS Inputs

_______________________________________________________________________________________ 5

Note 2: This parameter does not include update-rate-dependent effects of sin(x)/x filtering inherent in the MAX5890.

Note 3: Parameter measured single-ended with 50Ω double-terminated outputs.

Note 4: Not production tested. Guaranteed by design.

Note 5: Parameter defined as the change in midscale output caused by a ±5% variation in the nominal supply voltages.
