General-Purpose, Low-Voltage,
Single/Dual/Quad, Tiny-Pack Comparators
General Description
The LMX331/LMX393/LMX339 single/dual/quad com-
parators are drop-in, pin-for-pin-compatible replace-
ments for the LMV331/LMV393/LMV339. The LMX331H/
LMX393H/LMX339H offer the performance of the
LMX331/LMX393/LMX339 with the added benefit of inter-
nal hysteresis to provide noise immunity, preventing out-
put oscillations even with slow-moving input signals.
Advantages of the LMX331/LMX393/LMX339 series
include low supply voltage, small package, and low cost.
The LMX331 is available in both 5-pin SC70 and SOT23
packages, LMX393 is available in both 8-pin µMAX and
smaller SOT23 packages, and the LMX339 is available in
14-pin TSSOP and SO packages. They are manufac-
tured using advanced submicron CMOS technology.
Designed with the most modern techniques, the
LMX331/LMX393/LMX339 achieve superior performance
over BiCMOS or bipolar versions on the market.
The LMX331/LMX393/LMX339 offer performance
advantages such as wider supply voltage range, wider
operating temperature range, better CMRR and PSRR,
improved response time characteristics, reduced off-
set, reduced output saturation voltage, reduced input
bias current, and improved RF immunity.
