DD211
DD211B
DD211M*
A dual DD111 with current programming pins
omitted. This driver is often used in SPDT applications
by driving the inverting input of one channel and the
noninverting input of the other channel from the same
TTL input signal.
1. W hen using channel 1 inverting input pin 4, connect
bias pin 5 to non-inverting input pin 6.
2. W hen using channel 2 inverting input pin 11,.
connect bias pin 10 to non-inverting pin 9.
3. W hen using channel 1 non-inverting input pin 6,
connect bias pin 5 to inverting input pin 4.
4. W hen using channel 2 non-inverting input pin 9,
connect bias pin 10 to inverting input pin 11.
5. The two drivers are identical except for quiescent
positive output current, which is nominally 15 mA
for DD211 and 30 mA for DD211B.
6 W hen driving anode-grounded diodes, care must
be exercised to avoid excessive power dissipation.
V ee should be limited to -10 V, at which point the
negative output current will be approximately
-10 mA . Consult factory for design assistance.
