APPLICATION INFORMATION (continued)
The value of R3 in the previous equation can be reduced to increase the output current drive of U3. U3 can
drive ±20 mA in both directions with voltage compliance limited up to 15 V by the U3 voltage supply. Elimination
of the circuit compensation capacitor C1 in the circuit is not suggested because of the change in the output
As shown in Equation 4, with matched resistors, ZO is infinite and the circuit is optimum for use as a current
source. However, if unmatched resistors are used, ZO is positive or negative with negative output impedance
being a potential cause of oscillation. Therefore, by incorporating C1 into the circuit, possible oscillation
problems are eliminated. The value of C1 can be determined for critical applications; however, for most
applications a value of several pF is suggested.
The DAC8801 has an industry-standard pinout. Table 2 provides the cross-reference information.
