NOTES: 1. Gains below 1 and above 1000 are obtained by simply ad- justing the gain setting resistors. (Input voltage should be re- stricted to :t10V for gains equal to or less than 1.) 2. Nonlinearity is defined as ...

AD521 Where offset errors are critical, a resistor equal to the parallel combination of Rl and Rz should be placed between pin 11 and VREF. This minimizes the offset errors resulting from the input current flowing in Rl and Rz ...
