Further, they can drive lamps or relays, switching voltagesup to 50V at currents as high as 50mA.INPUT2+7OUTPUTBoth the inputs and the outputs of the LM111 series can be isolatedINPUT3–6BAL/STROBEfrom system ground, and the output can drive loads referred toground, the positive supply, or the negative supply. Offset balancingV–45BALANCEand strobe capability are provided and outputs can be wire-ORed.Although slower than the µA710 (200ns response time vs 40ns), thedevices are also much less prone to spurious oscillations. The LM111APPLICATIONSseries has the same pin configuration as the µA710 series.•Precision squarerFEATURES•Positive/negative peak detector•Operates from single 3V supply (LM311B)•Low voltage adjustable reference supply•Maximum input bias current: 150nA (LM311—250nA)•Switching power amplifier•Maximum offset current: 20nA (LM311—50nA)•Differential input voltage range: ±30V•Power consumption: 135mW at ±15V•High sensitivity—200V/mV•Zero crossing detectorORDERING INFORMATIONDESCRIPTIONTEMPERATURE RANGEORDER CODEDWG #8-Pin Plastic Dual In-Line Package (DIP)-55°C to +125°CLM111N0404B8-Pin Plastic Dual In-Line Package (DIP)-25°C to +85°CLM211N0404B8-Pin Plastic Small Outline Package (SO)0 to +70°CLM311D0174C8-Pin Plastic Dual In-Line Package (DIP)0 to +70°CLM311N0404B8-Pin Plastic Small Outline Package (SO)-25°C to +85°CLM211D0174C8-Pin Ceramic Dual In-Line Package (CERDIP)-55°C to +125°CLM111FE0580A8-Pin Plastic Small Outline Package (SO)0 to +70°CLM311BD0174C8-Pin Plastic Dual In-Line Package (DIP)0 to +70°CLM311BN0404BAugust 31, 1994273853-0927 13721元器件交易网www.cecb2b.comPhilips Semiconductors Linear ProductsProduct specificationVoltage comparatorLM111/211/311/LM311BEQUIVALENT SCHEMATICBALANCE/STROBEBALANCEV+R3R1R4R2R8R93001.3K3001.3K750600Q8Q7Q10R5Q2070Q11Q12R6R7Q51.2K1.2KQ13Q19R10Q84KOUTPUTQ14Q3Q9Q18Q1D1D2Q4R17R155V5V60400R11130Q2INPUTSQ15Q23R15450R12600Q2Q22Q18R19R18R142502002KQ17R134V– ABSOLUTE MAXIMUM RATINGSSYMBOLPARAMETERRATINGUNITVSTotal supply voltage36VOutput to negative supply voltage:LM111/LM21150VLM311/LM311B40VGround to negative supply voltage30VDifferential input voltage±30VVINInput voltage1±15VPD MAXMaximum power dissipation,TA=25°C (still-air)2F package810mWN package1190mWD package780mWIOutput short-circuit duration10secTAOperating ambient temperature rangeLM111-55 to +125°CLM211-25 to +85°CLM311/LM311B0 to +70°CTSTGStorage temperature range-65 to +150°CTLead soldering temperature SOLD(10sec max)300°CNOTES:1.This rating applies for ±15V supplies.
