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
impedance ZO, according to Equation 4:
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.
