The NCS333 and NCS325 from ON Semiconductor are precision operational amplifiers with a very low input-offset voltage, enabling them to achieve high output accuracy. They also feature near-zero drift over time and temperature.

When used in motor-control feedback and power-supply control loops, the NCS325 and NCS333 op amps provide for very high accuracy, thereby helping designers to achieve high system efficiency. The NCS333 has a maximum input-offset voltage of 10μV at an ambient temperature of 25°C. For the NCS325, this value is 50μV.

Featuring a typical 30nV/°C of offset temperature drift, these op amps are very well suited to low-side current sensing and voltage-differential measurement in front-end sensor functions.

  • 17μA quiescent current at 3.3V (NCS333)
  • 21μA quiescent current at 3.3V (NCS325)
  • Open-loop voltage gain: 114dB (NCS325) / 145dB (NCS333)
