INA280 2.7-V to 120-V, 1.1-MHz, High Precision Current Sense Amplifier in Small

(SC-70) Package

1 Features

3 Description

•

Wide common-mode voltage:

– Operational voltage: 2.7 V to 120 V

– Survival voltage: −20 V to +122 V

Excellent CMRR:

– 120-dB DC (Minimum)

– 85-dB AC at 50 kHz

Accuracy

The INA280 is a current sense amplifier that can

measure voltage drops across shunt resistors over a

wide common-mode range from 2.7 V to 120 V. It is in

a highly space-efficient SC-70 package with a PCB

footprint of only 2.0 mm × 2.1 mm. The current

measurement accuracy is achieved thanks to the

combination of an ultra-low offset voltage of ±150 µV

(maximum), a small gain error of ±0.5% (maximum),

and a high DC CMRR of 140 dB (typical). The INA280

is not only designed for DC current measurement, but

also for high-speed applications (like fast overcurrent

protection, for example) with a high bandwidth of 1.1

MHz (at gain of 20 V/V) and an 85-dB AC CMRR (at

50 kHz).

– Gain:

•

Gain error: ±0.5% (maximum)

Gain drift: ±20 ppm/°C (maximum)

– Offset:

•

Offset voltage: ±150 µV (maximum)

Offset drift: ±1 µV/°C (maximum)

The INA280 operates from a single 2.7-V to 20-V

supply and draws a 370-μA supply current (typical).

The INA280 available with five gain options: 20 V/V,

50 V/V, 100 V/V, 200 V/V, and 500 V/V. The low offset

and drift of the INA280 enables accurate current

sensing over the extended operating temperature

range of −40°C to +125°C.

•

Available gains:

– INA280A1: 20 V/V

– INA280A2: 50 V/V

– INA280A3: 100 V/V

– INA280A4: 200 V/V

– INA280A5: 500 V/V

High bandwidth: 1.1 MHz

Slew rate: 2 V/µs
