Rainbow Electronics LMX339 User Manual

General Description

The LMX331/LMX393/LMX339 single/dual/quad com­parators are drop-in, pin-for-pin-compatible replace­ments for the LMV331/LMV393/LMV339. The LMX331H/
LMX393H/LMX339H offer the performance of the
LMX331/LMX393/LMX339 with the added benefit of inter­nal hysteresis to provide noise immunity, preventing out­put 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 manufac­tured 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 off­set, reduced output saturation voltage, reduced input
bias current, and improved RF immunity.

DC ELECTRICAL CHARACTERISTICS—2.7V OPERATION

(VDD= 2.7V, VSS= 0, VCM= 0, RL= 5.1kΩ connected to VDD. Typical values are at TA= +25°C.) (Note 1)

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional
operation of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to
absolute maximum rating conditions for extended periods may affect device reliability.
