LMV393MM/NOPB Electronic IC Chips General Purpose , Low Voltage Comparators

LMV331 Single / LMV393 Dual / LMV339 Quad

General Purpose, Low Voltage, TinyPack Comparators

General Description

The LMV393 and LMV339 are low voltage (2.7-5V) versions of the dual and quad comparators, LM393/339, which are specified at 5-30V. The LMV331 is the single version, which is available in space saving SC70-5 and SOT23-5 packages. SC70-5 is approximately half the size of SOT23-5.

The LMV393 is available in 8-pin SOIC and 8-pin MSOP. The LMV339 is available in 14-pin SOIC and 14-pin TSSOP.

The LMV331/393/339 is the most cost-effective solution where space, low voltage, low power and price are the primary specification in circuit design for portable consumer products. They offer specifications that meet or exceed the familiar LM393/339 at a fraction of the supply current.

The chips are built with National’s advanced Submicron Silicon-Gate BiCMOS process. The LMV331/393/339 have bipolar input and output stages for improved noise performance.

Note 1: Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for which the device is intended to be functional, but specific performance is not guaranteed. For guaranteed specifications and the test conditions, see the Electrical characteristics.

Note 2: : Human body model, 1.5kΩ in series with 100 pF. Machine model, 200Ω in series with 100 pF.

Note 3: The maximum power dissipation is a function of TJ(max), θJA, and TA. The maximum allowable power dissipation at any ambient temperature is PD = (TJ(max) - TA)/θJA. All numbers apply for packages soldered directly into a PC board.
