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.
