DESCRIPTION

• CHOICE OF GAINS:

The INA210, INA211, INA212, INA213, and INA214

are voltage output current shunt monitors that can

– INA211: 500V/V

sense drops across shunts at common-mode

– INA212: 1000V/V

voltages from –0.3V to 26V, independent of the

supply voltage. Five fixed gains are available: 50V/V,

– INA213: 50V/V

100V/V, 200V/V, 500V/V, or 1000V/V. The low offset

– INA214: 100V/V

of the Zerø-Drift architecture enables current sensing

• QUIESCENT CURRENT: 100μA (max)

with maximum drops across the shunt as low as

10mV full-scale.

• SC70 PACKAGE: All Models

• THIN QFN PACKAGE: INA210, INA213, INA214

These devices operate from a single +2.7V to +26V

power supply, drawing a maximum of 100μA of

supply current. All versions are specified over the

extended operating temperature range (–40°C to

+125°C), and offered in an SC70 package. The

INA210, INA213, and INA214 are also offered in a

thin QFN package.

INA210, INA211 INA212, INA213 INA214 SBOS437E – MAY 2008 – REVISED JUNE 2013 www.ti.com UNIDIRECTIONAL OPERATION Unidirectional operation allows the INA210-INA214 to measure currents through a resistive shunt in one direction. The most frequent case of unidirectional operation sets the output at ground by connecting the REF pin to ground.
PAGE 11
INA210, INA211 INA212, INA213 INA214 www.ti.com SBOS437E – MAY 2008 – REVISED JUNE 2013 The amount of variance in the differential voltage present at the device input relative to the voltage developed at the shunt resistor is based both on the external series resistance value as well as the internal input resistors, R3 and R4 (or RINT as shown in Figure 24).

INA210, INA211 INA212, INA213 INA214 SBOS437E – MAY 2008 – REVISED JUNE 2013 www.ti.com SHUTTING DOWN THE INA210-INA214 SERIES While the INA210-INA214 series does not have a shutdown pin, its low power consumption allows powering from the output of a logic gate or transistor switch that can turn on and turn off the INA210-INA214 power-supply quiescent current. However, in current shunt monitoring applications.

INA210, INA211 INA212, INA213 INA214 www.ti.com SBOS437E – MAY 2008 – REVISED JUNE 2013 REF INPUT IMPEDANCE EFFECTS As with any difference amplifier, the INA210-INA214 series common-mode rejection ratio is affected by any impedance present at the REF input. This concern is not a problem when the REF pin is connected directly to most references or power supplies. When using resistive dividers from the power supply or a reference voltage, the REF pin should be buffered by an op amp.

INA210, INA211 INA212, INA213 INA214 SBOS437E – MAY 2008 – REVISED JUNE 2013 www.ti.com USING THE INA210 WITH COMMON-MODE TRANSIENTS ABOVE 26V With a small amount of additional circuitry, the INA210-INA214 series can be used in circuits subject to transients higher than 26V, such as automotive applications. Use only zener diode or zener-type transient absorbers (sometimes referred to as Transzorbs)— any other type of transient absorber has an unacceptable time delay.
PAGE 15
INA210, INA211 INA212, INA213 INA214 www.ti.com SBOS437E – MAY 2008 – REVISED JUNE 2013 In the event that low-power zeners do not have sufficient transient absorption capability and a higher power transzorb must be used, the most package-efficient solution then involves using a single transzorb and back-toback diodes between the device inputs. The most space-efficient solutions are dual series-connected diodes in a single SOT-523 or SOD-523 package. This method is shown in Figure 28.

INA210, INA211 INA212, INA213 INA214 SBOS437E – MAY 2008 – REVISED JUNE 2013 www.ti.com IMPROVING TRANSIENT ROBUSTNESS Applications involving large input transients with excessive dV/dt above 2kV per microsecond present at the device input pins may cause damage to the internal ESD structures on version A devices. This potential damage is a result of the internal latching of the ESD structure to ground when this transient occurs at the input.
