INA28x-Q1 Automotive Grade, –14-V to +80-V, Bidirectional, High Accuracy,

Low- or High-Side, Voltage Output, Current Shunt Monitor

1 Features

3 Description

The INA28x-Q1 family includes the INA282-Q1,

INA283-Q1, INA284-Q1, INA285-Q1, and INA286-Q1

devices. These devices are voltage output current

shunt monitors that can sense drops across shunts at

common-mode voltages from –14 V to +80 V,

independent of the supply voltage. The low offset of

the zero-drift architecture enables current sensing

with maximum drops across the shunt as low as 10

mV full-scale.

•

Qualified for Automotive Applications

•

AEC-Q100 Qualified With the Following Results

–

Device Temperature Grade 1: –40°C to

+125°C Ambient Operating Temperature

Range

–

Device HBM ESD Classification Level H2

Device CDM ESD Classification Level C5

•

Wide Common-Mode Range: –14 V to +80 V

Offset Voltage: ±20 μV

CMRR: 140 dB

These current sense amplifiers operate from a single

2.7-V to 18-V supply, drawing a maximum of 900 μA

of supply current. These devices are specified over

the extended operating temperature range of –40°C

to +125°C, and offered in SOIC-8 and VSSOP-8

packages.
