Wide Supply Range, Rail-to-Rail Output

Instrumentation Amplifier with a Minimum Gain of 5

Check for Samples: INA827

FEATURES

DESCRIPTION

The INA827 is a low-cost instrumentation amplifier

(INA) that offers extremely low power consumption

and operates over a very wide single- or dual-supply

range. The device is optimized for the lowest possible

gain drift of only 1 ppm per degree Celsius in G = 5,

which requires no external resistor. However, a single

external resistor sets any gain from 5 to 1000.

Eliminates Errors from External Resistors at

Gain of 5

•

Common-Mode Range Goes Below

Negative Supply

•

Input Protection: Up to ±40 V

Rail-to-Rail Output

The INA827 is optimized to provide excellent

common-mode rejection ratio (CMRR) of over 88 dB

(G = 5) over frequencies up to 5 kHz. In G = 5,

CMRR exceeds 88 dB across the full input common-

mode range from the negative supply all the way up

to 1 V of the positive supply. Using a rail-to-rail

output, the INA827 is well-suited for low-voltage

operation from a 2.7 V single-supply as well as dual

supplies up to ±18 V. Additional circuitry protects the

inputs against overvoltage of up to ±40 V beyond the

power supplies by limiting the input currents to a save

level.

Outstanding Precision:

–

Common-Mode Rejection: 88 dB, min

Low Offset Voltage: 150 µV, max

Low Drift: 2.5 µV/°C, max

Low Gain Drift: 1 ppm/°C, max (G = 5 V/V)

Power-Supply Rejection:

100 dB, min (G = 5)

–

Noise: 17 nV/√Hz, G = 1000 V/V

•

High Bandwidth:

–

G = 5: 600 kHz

The INA827 is available in a small MSOP-8 package

and is specified for the –40°C to +125°C temperature

range. For a similar instrumentation amplifier with a

gain range of 1 V/V to 1000 V/V, see the INA826.
