SBOS501F – JANUARY 2010 – REVISED FEBRUARY 2015 INA12x-HT Precision, Low-Power Instrumentation Amplifiers
1 Features 3 Description 2 Applications The INA128-HT and INA129-HT are low-power,
general-purpose instrumentation amplifiers offering
excellent accuracy. The versatile three-operationalamplifier design and small size make them ideal for a
wide range of applications. Current-feedback input
circuitry provides wide bandwidth even at high gain. A
single external resistor sets any gain from 1 to 10000.
The INA128-HT provides an industry-standard gain
equation; the INA129-HT gain equation is compatible
with the AD620. The INA128-HT and INA129-HT are laser trimmed for
very low offset voltage (25 ОјV Typ) and high
common-mode rejection (93 dB at G ≥ 100). These
devices operate with power supplies as low as В±2.25
V, and quiescent current of 2 mA, typically. Internal
input protection can withstand up to В±40 V without
damage. 1 Low Offset Voltage: 25 uV Typical
Low Input Bias Current: 50 nA Typical (1) …
