The ±0.5-mV Offset (typ) INA270 and INA271 pinouts readily enable filtering. ±0.2% Gain Error (typ) The INA270 and INA271 are available with two gain 2.5 μV/°C Offset Drift (typ) options: 14 V/V and 20 V/V. The 130-kHz bandwidth 50 ppm/°C Gain Drift (max) simplifies use in current-control loops. • Bandwidth: Up to 130 kHz The INA270 and INA271 operate from a single +2.7-V • Two Gain Options Available: to +18-V supply, drawing 700 μA (typical) of supply 14 V/V (INA270) current. The devices are specified over the extended 20 V/V (INA271) operating temperature range of –40°C to +125°C and are offered in an SOIC-8 package. • Quiescent Current: 700 μA (typ) • Power Supply: +2.7 V to +18 V Device Information(1) • Provision for Filtering PART NUMBER PACKAGE BODY SIZE (NOM) INA27x SOIC (8) 4.90 mm × 3.91 mm 2 Applications (1) For all available packages, see the orderable addendum at • Power Management the end of the datasheet. • Automotive • Telecom Equipment • Notebook Computers • Battery Chargers • Cell Phones • Welding Equipment 1 An IMPORTANT NOTICE at the end of this data sheet addresses availability, warranty, changes, use in safety-critical applications, intellectual property matters and other important disclaimers.
