scale higher input voltages into a manageable mv range. i had trouble finding the resistors for the divider network as described, but was able to find these values which provide the same , , divide ratios: meg, k, . k, k + ohms. this alternate divider version is shown in figure . figure . alternate...
network. individual capacitors are connected or disconnected with switches based on the input. the r- r ladder dac which is a binary-weighted dac that uses a repeating cascaded structure of resistor values r and r. this improves the precision due to the relative ease of producing equal valued-matched resistors...
