Noise Performance

The INA114 provides very low noise in most applications. For differential source impedances less than 1kΩ, the INA103 can provide lower noise. For source impedances greater than 50kΩ, the INA111 FET-input instrumentation amplifier can provide lower noise.

Low frequency noise of the INA114 is approximately 0.4µVPP measured from 0.1Hz to 10Hz. This noise is approximately one-tenth the noise of low noise chopper-stabilized amplifiers.
