Its 3-op amp design and small size make it ideal for a wide range of applications. On-chip laser trimmed resistors accurately set a fixed gain of 100. The INA131 is laser trimmed to achieve very low offset voltage (50µV max), drift (0.25µV/°C max), and high CMR (110dB min). Internal input protection can withstand up to ±40V inputs without damage. The INA131 is available in a 8-pin plastic DIP. They are specified over the –40°C to +85°C temperature range.
