ELECTRICAL CHARACTERISTICS (continued)
(V+ = 5V, T
Note 1: The maximum output current of the MAX8211 is limited by design to 30mA under any operating condition. The output voltage
Note 2: The maximum output current of the MAX8212 is not defined, and systems using the MAX8212 must therefore ensure that the
As shown in the block diagrams of Figures 1 and 2, the
MAX8211 and MAX8212 each contain a 1.15V refer-
ence, a comparator, an open-drain n-channel output
transistor, and an open-drain p-channel hysteresis out-
put. The MAX8211 output n-channel turns on when the
voltage applied to the THRESH pin is less than the
internal reference (1.15V). The sink current is limited to
7mA (typical), allowing direct drive of an LED without a
series resistor. The MAX8212 output turns on when the
voltage applied to THRESH is greater than the internal
reference. It is not current limited, and will typically sink
35mA.
The CMOS MAX8211/MAX8212 are plug-in replacements
for the bipolar ICL8211/ICL8212 in most applications.
The use of CMOS technology has several advantages.
The quiescent supply current is much less than in the
bipolar parts. Higher-value resistors can also be used
