♠ INA281-Q1 AEC-Q100, -4-V ukuya 110-V, 1.3-MHz yangoku-Sense Amplifier
I-INA281-Q1 yi-high-precision yangoku ye-amplifier yangoku enokulinganisa ukuhla kwamandla ombane kwi-shunt resistors kwi-wide common-mode range ukusuka kwi-4 V ukuya kwi-110 V. I-voltage ye-mode-mode engalunganga ivumela isixhobo ukuba sisebenze ngaphantsi komhlaba, ngaloo ndlela sivumelane nomlinganiselo ochanekileyo wokujikeleza kwemisinga kwi-half-bridge applications. Ukudityaniswa kwamandla ombane asezantsi, impazamo encinci yokuzuza kunye ne-DC CMRR ephezulu yenza umlinganiselo ochanekileyo wangoku. I-INA281-Q1 ayenzelwanga kuphela ukulinganisa kwe-DC yangoku, kodwa kunye nezicelo zesantya esiphezulu (njengokhuseleko olukhawulezayo, umzekelo) kunye ne-bandwidth ephezulu ye-1.3 MHz kunye ne-65-dB AC CMRR (kwi-50 kHz).
I-INA281-Q1 isebenza ukusuka kwi-2.7-V enye ukuya kwi-20-V yokubonelela, ukudweba i-1.5 mA yokubonelela ngoku. I-INA281-Q1 ifumaneka ngeendlela ezintlanu zokufumana: 20 V / V, 50 V / V, 100 V / V, 200 V / V, kunye ne-500 V / V. Olu khetho luzuzayo lujongana noluhlu oluguquguqukayo olubanzi lwezicelo zovavanyo lwangoku.
I-INA281-Q1 icaciswa kuluhlu lweqondo lobushushu lokusebenza −40 °C ukuya +125 °C kwaye ibonelelwa ngephakheji ye-SOT-23 eyonga isithuba kunye neentlobo ezimbini ze-pin-out.
