Hi Olly, The modification for this circuit is simple, just leave the parallel feedback resistor disconnected (RFB2, pin10). This would make the total feedback resistance 10kohm instead of 5kohm. I created a TINA-TI simulation to test this. Note that the current-controlled current source and the voltage controlled current source is just to replicate the MDAC architecture of the DAC itself, which makes DC transfer function in TINA-TI easier. Here is the simulation: (Please visit the site to view this file) Thanks, Paul
