SBOS579B – SEPTEMBER 2011 – REVISED JULY 2012
High Common-Mode Voltage Difference Amplifier
1
FEATURES
DESCRIPTION
The INA149 is a precision unity-gain difference
2
Common-Mode Voltage Range: ±275 V
amplifier with a very high input common-mode
Minimum CMRR: 90 dB from –40°C to +125°C
voltage range. It is a single, monolithic device that
DC Specifications:
consists of a precision op amp and an integrated thin-
film resistor network. The INA149 can accurately
–
Maximum Offset Voltage: 1100
μV
measure small differential voltages in the presence of
–
Maximum Offset Voltage Drift: 15
μV/°C
common-mode signals up to ±275 V. The INA149
–
Maximum Gain Error: 0.02%
inputs are protected from momentary common-mode
or differential overloads of up to 500 V.
–
Maximum Gain Error Drift: 10 ppm/°C
–
Maximum Gain Nonlinearity: 0.001% FSR
In many applications, where galvanic isolation in not
required, the INA149 can replace isolation amplifiers.
AC Performance:
This ability can eliminate costly isolated input side
–
Bandwidth: 500 kHz
power supplies and the associated ripple, noise, and
–
Typical Slew Rate: 5 V/
μs
quiescent current. The excellent 0.0005% nonlinearity
and 500-kHz bandwidth of the INA149 are superior to
Wide Supply Range: ±2.0 V to ±18 V
those of conventional isolation amplifiers.
–
Maximum Quiescent Current: 900
μA
The INA149 is pin-compatible with the INA117 and
–
Output Swing on ±15-V Supplies: ±13.5 V
INA148 type high common-mode voltage amplifiers
Input Protection:
and offers improved performance over both devices.
–
Common-Mode: ±500 V
The INA149 is available in the SOIC-8 package with
operation specified over the extended industrial
–
Differential: ±500 V
temperature range of –40°C to +125°C.
APPLICATIONS
High-Voltage Current Sensing
Battery Cell Voltage Monitoring
Power-Supply Current Monitoring
Motor Controls
Replacement for Isolation Circuits
