♠ INA281-Q1 AEC-Q100, -4-V kusvika 110-V, 1.3-MHz Current-Sense Amplifier
I INA281-Q1 inyanzvi yepamusoro-soro yemazuva ano amplifier inokwanisa kuyera madonhwe emagetsi kune shunt resistors pamusoro pemhando yakawanda-yakawanda-mode kubva -4 V kusvika ku110 V. Izvo zvakashata zvinowanzoitwa-mode voltage inobvumira chigadziro kushanda pasi pevhu, nokudaro kugadzirisa kuyerwa kwakanyatsojeka kwekudzoka kwemhepo muhafu-bridge applications. Iko kusanganiswa kweiyo yakaderera offset voltage, diki kukanganisa kukanganisa uye yakakwira DC CMRR inogonesa kuyerwa kwazvino kwazvino. Iyo INA281-Q1 haina kugadzirirwa chete kuyera DC ikozvino, asiwo ye-high-speed application (senge inokurumidza overcurrent kudzivirira, semuenzaniso) ine bandwidth yakakwira ye1.3 MHz uye 65-dB AC CMRR (pa50 kHz).
Iyo INA281-Q1 inoshanda kubva kune imwechete 2.7-V kusvika 20-V inopihwa, kudhirowa 1.5 mA yekugovera ikozvino. Iyo INA281-Q1 inowanikwa neshanu dzekuwana sarudzo: 20 V/V, 50 V/V, 100 V/V, 200 V/V, uye 500 V/V. Aya anowana sarudzo kero yakafara dhizaini renji yeazvino sensorse application.
Iyo INA281-Q1 inotsanangurwa pamusoro petembiricha yekushanda ye -40 °C kusvika +125 °C uye inopihwa mune inochengetedza nzvimbo SOT-23 package ine maviri-pini-kunze akasiyana.
