AD8278/AD8279 THEORY OF OPERATION CIRCUIT INFORMATION Each channel of the AD8278 and AD8279 consists of a low power, low noise op amp and four laser-trimmed on-chip resistors. These resistors can be externally connected to make a variety of amplifier configurations, ...
Page 17
POWER SUPPLIES The AD8278 and AD8279 operate extremely well over a very wide range of supply voltages. They can operate on a single supply as low and as high under appropriate setup conditions. For ...

AD8278/AD8279 APPLICATIONS INFORMATION CONFIGURATIONS The AD8278 and AD8279 can be configured in several ways (see Figure 51 to Figure 57). These configurations have excellent gain accuracy and gain drift because they rely on the internal matched resistors. Note that Figure ...
Page 19
The reference must be driven with a low impedance source to maintain the internal resistor ratio. An example using the low power, low noise OP1177 as a reference is shown in Figure 58. INCORRECT CORRECT AD8278 REF ...
