Design INA128, INA129
SBOS051D – OCTOBER 1995 – REVISED JANUARY 2018 INA12x Precision, Low-Power Instrumentation Amplifiers
1 Features 3 Description The INA128 and INA129 are low-power, general
purpose instrumentation amplifiers offering excellent
accuracy. The versatile 3-op amp design and small
size make these amplifiers 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: 50 ОјV Maximum
Low Drift: 0.5 ОјV/В°C Maximum
Low Input Bias Current: 5 nA Maximum
High CMR: 120 dB minimum
Inputs Protected to В±40 V
Wide Supply Range: В±2.25 V to В±18 V
Low Quiescent Current: 700 ОјA
8-Pin Plastic Dip, SO-8 A single external resistor sets any gain from 1 to
10,000. The INA128 provides an industry-standard …
