描述The INA271 is a current-shunt monitor with voltage output and can sense drops across current shunts at common-mode voltages from –16V to +80V, independent of the supply voltage. The INA271 pinouts readily enable filtering. The INA271 is available with a 20V/V output voltage scale. The 130kHz bandwidth simplifies use in current-control loops. The INA271 operates from a single +2.7V to +18V supply, drawing a maximum of 1600µA of supply current. This device is specified over the extended operating temperature range of –55°C to +210°C.特性Wide Common-Mode Range: –16V to +80VCMRR: 78dBAccuracy: ±10mV Offset (max) ±7.5% Gain Error (max) 100µV/°C Offset Drift (max)Bandwidth: Up to 130kHzTransfer Function: 20V/VQuiescent Current: 1600µA (max)Power Supply: +2.7V to +18VProvision for Filtering APPLICATIONSDown-Hole Drilling High Temperature EnvironmentsSupports Extreme Temperature Applications Controlled Baseline One Assembly/Test Site One Fabrication Site Available in Extreme (–55°C/210°C) Temperature Range(1) Extended Product Life Cycle Extended Product-Change Notification Product Traceability Texas Instruments high temperature products utilize highly optimized silicon (die) solutions with design and process enhancements to maximize performance over extended temperatures.(1) Custom temperature ranges
