When measuring voltages beyond the supplies, there is additional offset error, bias currents increase, and input impedance decreases, especially at higher temperatures. 2 For G > 1, errors from the external resistors, R1 and R2, must be added to these specifications, including error from the FB pin bias current. 3 The AD8237 has only been characterized for gains of 1 to 1000; however, higher gains are possible. |
