The INA114 is a low-cost, general-purpose instrumentation amplifier offering excellent accuracy. The versatile three-op-amp design and small size make this device an excellent choice for a wide range of applications. A single external resistor sets any gain from 1 to 10,000. Internal input protection withstands up to ±40V without damage. The INA114 is laser trimmed for very low offset voltage (50µV), low drift (0.3µV/°C), and high common-mode rejection (115dB at G = 1000). The device operates with power supplies as low as ±2.25V, allowing use in battery-operated and single 5V supply systems. The INA114 is available in 8-pin PDIP and 16-pin SOIC surface-mount packages. Both are specified for a temperature range of −40°C to +85°C.
