BLAST (Pin 13):
Blast/Timer Function Input. This is a
multifunction digital input pin that controls blast and timer
operation. If this pin is in a logic high state at power-up or
is transitioned from high to low, it will “blast” the current
DAC outputs to full scale (100
μ
A) no matter what their
previous state was and set a fault condition. In addition, if
BLAST is in a logic high state, the serial access timer is
active; this circuit measures time between serial commu-
nications to the LTC1840 and forces a blast and trips a fault
if the part hasn’t been accessed for about 1.5 minutes. This
pin has a 1V logic threshold.
I
DACOUTB
(Pin 14):
Current DAC Output B. This is a high
impedance output with a sinking current output of 0
μ
A to
100
μ
A. This current can be programmed to one of 256
values through the serial interface or it can be “blasted”
immediately to full scale using the BLAST pin or by the
serial access timer if it is enabled and the LTC1840 is not
accessed for about 1.5 minutes. This pin will maintain the
programmed current to a very tight tolerance from as low
as 1.1V to at least 0.75V above V
CC
. The current DAC is
guaranteed to be monotonic over its full 8-bit range.
I
DACOUTA
(Pin 15):
Current DAC Output A. See I
DACOUTB
V
CC
(Pin 16):
Positive Supply. This pin must be closely
decoupled to ground (pin 8). A 10
μ
F tantalum and a 0.1
μ
F
ceramic capacitor in parallel are recommended.
