MAX136
Low Power, 3 1 ? 2 Digit A/D Converter
with Display Hold
Detailed Description
The MAX136 3? digit ADC is similar to the Maxim
ICL7136 except for the addition of a Hold pin. For a
detailed product description, and applications informa-
tion (other than the operation of the Hold pin described
below), refer to Maxim's ICL7136 data sheet.
Hold Input
The Hold input is a digital input with a logic thresh-
old approximately midway between V+ and Test. The
MAX136 continuously performs conversions, indepen-
dent of the Hold input. When the Hold input is at V+ the
display latch pulse is inhibited, and the display latches
0.47μF
are not updated; when the Hold input is low or at the
Test voltage, the display is updated at the end of each
conversion. The MAX136 maintains low-power dissipa-
tion even during display hold by eliminating the pulldown
resistor between Hold and Test present on the ICL7116.
The Hold input is CMOS compatible, and can also be
driven by a switch connected between Test and V+
(Figure 1).
Reference Input
Unlike the ICL7136, the MAX136 does not have a refer-
ence low input. Apply the reference voltage between
Reference High (REF HI) and
