INA128PA Instrumentation amplifier, 1-fold, 4 V/µs, 1.3 MHz, DIP-8

INA128PA Precision, 130-dB CMRR, 700-µA, Low-Power, Instrumentation Amplifier

Description: The INA128 and INA129 are low-power, general purpose instrumentation amplifiers offeringexcellent accuracy. The versatile 3-op amp design and small size make these amplifiers ideal for awide range of applications. Current-feedback input circuitry provides wide bandwidth even at highgain (200 kHz at G = 100). A single external resistor sets any gain from 1 to 10,000. The INA128 provides anindustry-standard gain equation; the INA129 gain equation is compatible with the AD620. The INA12x is available in 8-pin plastic DIP and SO-8 surface-mount packages, specifiedfor the -40°C to +85°C temperature range. The INA128 is also available in a dual configuration, theINA2128. The upgraded INA828 offers a lowerinput bias current (0.6 nA maximum) and lower noise (7 nV/vHz) at the samequiescent current. See the Device Comparsion Table for a selection of precision instrumentation amplifiersfrom Texas Instruments.
