SBOS508A – DECEMBER 2009 – REVISED DECEMBER 2015 INA129-EP Precision, Low Power Instrumentation Amplifiers
1 Features 3 Description The INA129-EP device is a low power, generalpurpose instrumentation amplifier offering excellent
accuracy. The versatile 3-op amp design and small
size make the device ideal for a wide range of
applications. Current-feedback input circuitry provides
wide bandwidth even at high gain (200 kHz at G =
100). 1 Low Offset Voltage
Low Input Bias Current
High CMR: 95 dB (Typical)
Inputs Protected to В±40 V
Wide Supply Range: В±2.25 V to В±18 V
Low Quiescent Current: 2 mA (Typical) A single external resistor sets any gain from 1 to
10,000. The INA129-EP provides an industrystandard gain equation; the INA129-EP gain equation
is compatible with the AD620. 2 Applications (1) Bridge Amplifier
Thermocouple Amplifier
RTD Sensor Amplifier
Medical Instrumentation …
