Zero Drift Operational Amplifiers

National features a rich portfolio of near zero input offset voltage drift op amps. National's zero-drift amplifiers use a breakthrough noise-shaping technology that employs continuous-correction circuitry to auto zero the input offset error voltage. This enables uninterrupted accuracy over time and temperature, with high common-mode rejection ratio (CMRR) and high power-supply rejection ratio (PSRR). These features are enabled through chopper amplifier technology that continuously corrects offset error while maintaining a high bandwidth and integrating the capacitors.

These products in the LMP precision amplifier family feature: Near zero input offset voltage drift Ultra low input offset voltage Very low input voltage noise with no 1/f noise component Very high open loop gain
