to +80V. The INA206, INA207, and INA208 are

• HIGH ACCURACY: 3.5% (max) OVER TEMP

available with three output voltage scales: 20V/V,

• BANDWIDTH: 500kHz

50V/V, and 100V/V, with up to 500kHz bandwidth.

• QUIESCENT CURRENT: 1.8mA

The INA206, INA207, and INA208 also incorporate

• PACKAGES: SO-14, TSSOP-14, MSOP-10

two open-drain comparators with internal 0.6V

references. On 14-pin versions, the comparator

references can be overridden by external inputs.

• NOTEBOOK COMPUTERS Comparator 1 includes a latching capability, and

Comparator 2 has a user-programmable delay on

INA206 INA207 INA208 www.ti.com SBOS360E – JUNE 2006 – REVISED OCTOBER 2007 APPLICATIONS INFORMATION This section addresses the accuracy of these specific operating regions: BASIC CONNECTION Figure 30 shows the basic connection of the INA206, INA207, and INA208. The input pins, VIN+ and VIN–, should be connected as closely as possible to the shunt resistor to minimize any resistance in series with the shunt resistance.
PAGE 13
INA206 INA207 INA208 www.ti.com SBOS360E – JUNE 2006 – REVISED OCTOBER 2007 Normal Case 2: VSENSE ≥ 20mV, VCM < VS This region of operation has slightly less accuracy than Normal Case 1 as a result of the common-mode operating area in which the part functions, as seen in the Output Error vs Common-Mode Voltage curve. As noted, for this graph VS = 12V; for VCM < 12V, the Output Error increases as VCM becomes less than 12V, with a typical maximum error of 0.005% at the most negative VCM = –16V.

INA206 INA207 INA208 www.ti.com SBOS360E – JUNE 2006 – REVISED OCTOBER 2007 TRANSIENT PROTECTION OUTPUT VOLTAGE RANGE The –16V to +80V common-mode range of the INA206, INA207, and INA208 is ideal for withstanding automotive fault conditions ranging from 12V battery reversal up to +80V transients, since no additional protective components are needed up to those levels.
PAGE 15
INA206 INA207 INA208 www.ti.com SBOS360E – JUNE 2006 – REVISED OCTOBER 2007 Note that the specified accuracy of the INA206, INA207, and INA208 must then be combined in addition to these tolerances. While this discussion treated accuracy worst-case conditions by combining the extremes of the resistor values, it is appropriate to use geometric mean or root sum square calculations to total the effects of accuracy variations.
