Electrical Characteristics: WM5620 & WM5620L (continued)
11 Reference feedthrough is measured at a DAC out-
put with an input code = 00 Hex with a VREF input = 1
Vdc + 1 VPP at 10kHz
12. Channel to channel isolation is measured at a DAC
output with an input code of one DAC to FF Hex and
the code oa all other DACs to oo Hex with a VREF
input = 1 Vdc + 1 Vpp at 10kHz
13 Setting time is the time for the output signal to remain
within ±0.5 LSB of the final measurement value for a
digital input code change of 00 Hex to FF Hex. For WM
5620: VDD = 5V, VREF = 2V and range = x 2. For
WM5620L: VDD = 3, VREF = 1.25V and range = x 2.
14 Reference bandwidth is the -3dB bandwidth with an
input at VREF = 1.25 Vdc =+ 2 Vpp with a digital input
