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.
