NOTES: 1. A single resistor string is composed of 4 Runit + 4 Runit + 2 Runit + 2 Runit + 1 Runit + 1 Runit + 1 Runit + 1 Runit = 16 Runit = Rtotal.
2. For the matching (i.e. the relative accuracy) of the unit resistors on a device refer to the gain and level specifications of the respective
configurations.
