Description

The INA129UA/2K5 is low power, general purpose instrumentation amplifiers offering excellent accuracy. The versatile 3-op amp design and small size make them ideal for a wide range of applications. Current-feedback input circuitry provides wide bandwidth even at high gain (200kHz at G = 100). A single external resistor sets any gain from 1 to 10,000. The INA129UA/2K5 provides an industry-standard gain equation; the INA129UA/2K5 gain equation is compatible with the AD620. The INA129UA/2K5 is laser trimmed for very low offset voltage (50µV), drift (0.5µV/°C) and high common-mode rejection (120dB at G ≥ 100). It operates with power supplies as low as ±2.25V, and quiescent current is only 700µA—ideal for batteryoperated systems. Internal input protection can withstand up to ±40V without damage. The INA129UA/2K5 is available in 8-pin plastic DIP and SO-8 surface-mount packages, specified for the –40°C to +85°C temperature range. The INA129UA/2K5 is also available in a dual configuration, INA129UA/2K5 Features • Low Offset Voltage: 50µv Max• Low Drift: 0.5µv/c Max• Low Input Bias Current: 5na Max• High Cmr: 120db Min• Inputs Protected To 40v• Wide Supply Range: 2.25v To 18v• Low Quiescent Current: 700µa• 8-pin Plastic Dip, So-8 INA129UA/2K5 Applications • Bridge Amplifier• Thermocouple Amplifier• Rtd Sensor Amplifier• Medical Instrumentation• Data Acquisition• Portable Battery Powered Equipment
