Description

0.2 μV/°C Offset Drift (Typ)

–

10 ppm/°C Gain Drift (Max)

–

The TPA191Q series of zero-drift, bi-directional current

sense amplifiers can sense voltage drops across shunts at

common-mode voltages from −0.3 V to 36 V, independent

of the supply voltage. Multiple fixed gains are available:

20 V/V, 50 V/V, 75 V/V, 100 V/V, 200 V/V, 500 V/V,

and 1000 V/V. The integrated gain resistor network is

highly matched, which minimizes gain errors and reduces

the temperature drift. The low offset of the zero-drift

architecture extends the range of current sensing, it allows

for smaller sense resistors with lower power loss, while still

ensuring accurate current measurements.

Multiple Gain Options for Voltage Output

TPA191A1Q: 20 V/V

–

TPA191A2Q: 50 V/V

TPA191A3Q: 75 V/V

TPA191A4Q: 100 V/V

TPA191A5Q: 200 V/V

TPA191A6Q: 500 V/V

The TPA191Q devices operate from a single 2.7-V to 36-V

power supply, drawing a typical 80-μA supply current. All

versions are specified from −40°C 125°C, and offered in

the SOT363 package.
