The on-chip resistors are laser trimmed for accurate gain and high commonmode rejection. Excellent TCR tracking of the resistors maintains gain accuracy and common-mode rejection over temperature. The input common-mode voltage range extends beyond the positive and negative supply rails. It operates on ±4V to ±18V supplies. The difference amplifier is the foundation of many commonly used circuits. The INA154 provides this circuit function without using an expensive precision resistor network. The INA154 is available in a SO-8 surface-mount package and is specified for operation over the extended industrial temperature range, –40°C to +85°C. 25kΩ V+ 7 25kΩ ...
