The TP199 series of zero-drift, bi-directional current sense
amplifier can sense voltage drops across shunts at
common-mode voltages from 0.3V to 36V, independent of the
supply voltage. Two fixed gains are available: 50V/V, and
100V/V. The low offset of the zero-drift architecture enables
current sensing with maximum drops across the shunt as low
as 10mV full-scale.
TP199 devices operate from a single +2.7V to 36V power
supply, with drawing a typical of 120uA of supply current. All
versions are specified from 40°C +125°C, and offered in
SC70-6 packages.

Note 1: Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to
any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2: The op amp supplies must be established simultaneously, with, or before, the application of any input signals.
Note 3: The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the
power supply, the input current should be limited to less than 10mA.
Note 4: A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power
supply voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the
package. The specified values are for short traces connected to the leads.
