The RS631B device is a low-power, precision instrumentation amplifier offering excellent accuracy. The versatile 3-operational amplifier design, small size, and low power make it ideal for a wide range of portable applications. Provides multiple fixed gain configurations. The RS631B device provides very low offset voltage (±70μV), and high common-mode rejection (110dB). It operates with power supplies as low as 4.6V (±2.3V) and quiescent current is only 3.4mA, making it ideal for battery operated systems. Using autocalibration techniques to ensure excellent precision over the extended industrial temperature range. The RS631B device is available in SOP8 packages. It operates over an ambient temperature range of −40°C to +125°C.
