3 Description
The INA310x is an ultra-precise current sense
amplifier that can measure voltage drops across
shunt resistors over a wide common-mode range
from –4 V to 110 V, independent of supply voltage
with an integrated comparator. The high precision
current measurement accuracy is achieved through a
combination of low offset voltage (20 μV, maximum),
small gain error (0.15, maximum) and a high DC
CMRR (160 dB, typical). The INA310x has a high
signal bandwidth of 1.3 MHz designed for high
voltage DC current measurements and high-speed
applications like fast overcurrent protection.
The INA310x incorporates an open-drain comparator
and internal reference that provides a 0.6 V threshold.
An external resistive divider sets the current trip point.
The comparator includes a latching capability that can
be made transparent by grounding (or leaving open)
the RESET pin.
The INA310x operates from a single 2.7 V to 20 V
supply and draws 1.6 mA of supply current. The
INA310x is available in five gain options: 20 V/V,
50 V/V, 100 V/V, 200 V/V, and 500 V/V. These gain
options address a wide dynamic range of currentsensing
applications.
The INA310x is specified over an operating
temperature range of −40°C to +125°C and is offered
in a space-saving 8-pin VSSOP package.
