The q denotes specifications which apply over the full operating
temperature range.
Note 1: Supply current is tested with COMPIN+ = (REF – 100mV).
Note 2: Input offset voltage is defined as the center of the input referred
hysteresis, VCM = REF.
Note 3: Trip point is defined as the differential input voltage required to
make the comparator output change state. The difference between upper
and lower trip point is equal to the width of the input referred hysteresis,
VCM = REF.
Note 4: The input leakage current is measured for COMPIN+ at 1.5V.
PIN FUNCTIONS
AMPOUT (Pin 1): Op Amp Output. The output can swing
from rail-to-rail while driving a capacitive load of up to
1000pF.
AMPIN– (Pin 2): Inverting Input of Op Amp. The input
common mode ranges from VSS to VCC – 1.3V. The input
current is typically 10pA at 25°C.
AMPIN+ (Pin 3): Noninverting Input of Op Amp. The input
common mode ranges from VSS to VCC – 1.3V. The input
current is typically 10pA at 25°C.
VSS (Pin 4): Negative Supply or Ground Connection.
COMPIN+ (Pin 5): Noninverting Input of Comparator. The
input common mode ranges from VSS to VCC – 1.3V. The
input current is typically 10pA at 25°C.
REF (Pin 6): Reference Output. VREF = 1.2V ±1% over
industrial temperature range, and is also connected to
inverting comparator input internally. This device can
source up to 2mA and sink up to 20µA. The output can
drive a bypass capacitor of up to 0.01µF without oscilla-
tion.
COMPOUT (Pin 7): Comparator Output. The output can
source 20mA and sink 5mA.
VCC (Pin 8): Positive Supply, 2.5V ≤ VCC ≤ 12.6V. The supply
bypass capacitors are not required if the supply impedance
is low. For single supply applications, it is a good general
practice to bypass VCC with a 0.1µF capacitor to ground.
