If alow offset operational amplifier (AD510L, AD517L, AD741L, AD301AL, AD OP-07) is used, excellent performance can be obtained in many situations without trim- ming (an op amp with less than 0.5mV max offset voltage should be used to keep offset errors below 1/2LSB). If a 5022 fixed resistor is substituted for the 100Q trimmer, unipolar zero will typically be within +1/2LSB (plus op amp offset), and full scale accuracy will be within 0.1% (0.25% max), Substituting a 50Q resistor for the 10022 bipolar offset trim- mer will give a bipolar zero error typically within +2LSB (0.05%). The AD509 is recommended for buffered voltage-output appli- cations which require a settling time to +1/2LSB of one micro- second.

General Ground Management: AC or transient voltages be- tween AGND and DGND can cause noise injection into the analog output. The simplest method of ensuring that voltages at AGND and DGND are equal is to tie AGND and DGND together at the AD7545, In more complex systems where the AGND and DGND intertie is on the backplane, it i
