T he outputs can withstand an indefinite short-circuit to AGND
to typically 50 mA. T he output may also be shorted to any volt-
age between V
DD
and V
SS
; however, care must be taken to not
exceed the device maximum power dissipation.
T he amplifier’s emitter follower output stage consists of an in-
trinsic NPN bipolar transistor with a 400
μ
A NMOS pull-down
current-source load connected to V
SS
. T his circuit configuration
shown in Figure 4 enables the output amplifier to develop out-
put voltages very close to AGND. Only the negative supply of the
four output buffer amplifiers are connected to V
SS
. Operating
the DAC8426 from dual supplies (V
DD
= +15 V and V
SS
= –5 V)
improves negative going output settling time near zero volts.
When operating single supply (V
DD
= +15 V and V
SS
= 0 V) the
output sink current decreases as the output approaches zero
voltage. Within 200 mV of AGND (single-supply operation) the
internal sinking capability appears resistive at a value of approxi-
mately 1200
. T he buffer amplifier output current and voltage
characteristics are plotted in Figure 5.
