output buffer amplifier
The unity-gain output amplifier is capable of sourcing 5 mA into a 2-k
load and can drive a 3300-pF capacitor.
The output can be shorted to AGND indefinitely or it can be shorted to any voltage between VSS and VDD
consistent with the maximum device power dissipation.
multiplying DAC
The TLC7226 can be used as a multiplying DAC when the reference signal is maintained between 2 V and
VDD 4 V. When this configuration is used, VDD should be 14.25 V to 15.75 V. A low output-impedance buffer
should be used so that the input signal is not loaded by the resistor ladder. Figure 14 shows the general
schematic.
