Temperature Monitor
Each device supplies a single temperature output signal
(TEMP) that asserts a nominal +3.43V output voltage
at a +70NC (343K) die temperature. The output voltage
increases proportionately with temperature at a rate of
10mV/NC. The temperature sensor output impedance is
17kI (typ).
Serial Interface and Device Control
A CMOS-compatible serial interface controls the IC
modes (Figure 5). Control data flow into a 12-bit shift
register (LSB first) and are latched when CS is taken
high. Data from the shift register are then loaded to
the per-channel control latches, as determined by bits
five mode bits for each channel of the device. The mode
bits, in conjunction with external inputs DATA_ and
RCV_, manage the features of each channel. Transfer
data asynchronously from the input registers to the chan-
nel registers by forcing LD low. With LD always low, data
transfer on the rising edge of CS.
Heat Removal
With adequate airflow, no external heat sinking is needed
under most operating conditions. If excess heat must be
dissipated through the exposed pad, solder it to circuit-
board copper. The exposed pad must be either left
unconnected, isolated, or connected to GND.
Power Minimization
To minimize power consumption, activate only the need-
ed channels. Each channel placed in low-leakage mode
saves approximately 240mW.
