They have a single supply operating voltage range from 2.7V to 5.5V; the common mode input voltage range extends from -0.1V below the negative supply to within 0.8V of the positive supply. The LMV331/393 series is built using the BiCMOS process with bipolar input and output stages for improved noise performance. It is a costeffective solution for portable consumer products where space, low voltage, low power and price are the primary specification in circuit design. Basic Comparator A basic comparator circuit is used for converting analog signal to digital output. The LMV331/393 has open-collector output structure, which required a pull-high resistor to positive supply voltage for the output to switch properly. When the internal output transistor is off, the output voltage will be pulled up to the external positive voltage. The output pull- up resistor should be chosen high enough so as to avoid excessive power dissipation, yet low enough to supply enough drive to switch whatever load circuitry is used on the comparator output. On the LMV331/393 the pull-up resistor should range between 1KΩ to 10KΩ. Power Supply Bypassing For better performance, power supply bypass capacitor is necessary. For a single-supply operation system, a minimum of 0.1µF bypass capacitor should be recommended to place as close as possible between V CC pin and GND. vcc CBYPASS RL(LOAD) +VIN + LMV331/393 +VREF LMV331/ LMV393 Document number: DS37022 Rev. 2 - 2 Vo - 8 of 13 www.diodes.com August 2015 © Diodes Incorporated LMV331/ LMV393 Typical Application Circuit ADVANCED INFORMATION Vcc 5V 5.1KΩ +VIN 10KΩ +VIN + Vo Vo LMV331/393 LMV331/393 - +VREF + - +VREF Basic Comparator Driving CMOS/TTL VCC VCC 4.3KΩ 100KΩ 1MΩ 100pF 10KΩ - 0 0 - 1MΩ t0 VCC 75pF + 1:100KHz Vo 1N914 Vo VCC + 1ms 0.001uF 100KΩ PW t0 t1 0 + 100KΩ VCC 1MΩ 100KΩ 1N914 One-Shot Multivibrator Squarewave Oscillator VCC VCC 3KΩ - +VIN Vo +VREF 1MΩ + VCC Vo 1MΩ 1MΩ Inverting Comparator with Hysteresis LMV331/ LMV393 Document number: DS37022 Rev. 2 - 2 3KΩ - 10KΩ + +VIN 10MΩ Non-Inverting Comparator with Hysteresis 9 of 13 www.diodes.com August 2015 © Diodes Incorporated LMV331/ LMV393 Ordering Information Channel Package Single : 31 Dual : 93 W5 SE S M8 Part Number Package Code Packaging LMV331W5-7 LMV331SE-7 LMV393S-13 LMV393M8-13 W5 SE S M8 SOT25 SOT353 SO-8 MSOP-8 Packing : SOT25 : SOT353 : SO-8 : MSOP-8 7/13 : Tape & Reel 7”/13” Tape and Reel Quantity Part Number Suffix 3,000/Tape & Reel -7 3,000/Tape & Reel -7 2,500/Tape & Reel -13 2,500/Tape & Reel -13 Marking Information (1) SOT25 and SOT353 (Top View) 5 4 7 ADVANCED INFORMATION LMV3 XX XX - X XX Y W X 1 2 3 Device LMV331W5 LMV331SE (2) XX : Identification Code Y : Year : 0~9 W : Week : A~Z : 1~26 week; a~z : 27~52 week; z represents 52 and 53 week X : Internal Code Package type SOT25 SOT353 Identification Code CX CY SO-8 (Top View) 8 7 6 5 Logo 2 1 (3) YY : Year : 08, 09,10~ WW : Week : 01~52; 52 represents 52 and 53 week X X : Internal Code LMV393 YY WW X X Part Number 3 4 MSOP-8 ( Top View ) 8 7 Logo LMV393 1 Document number: DS37022 Rev. 2 - 2 5 YWX Part Number LMV331/ LMV393 6 2 3 Y : Year : 0~9 W : Week : A~Z :1~26 week; a~z : 27~52 week; z represents 52 and 53 week X : Internal Code 4 10 of 13 www.diodes.com August 2015 © Diodes Incorporated LMV331/ LMV393 Package Outline Dimensions (All dimensions in mm.)
