New Ultra-Low Power Precision Op-Amps

ON Semiconductor recently unveiled a new family of ultra-low power precision operational amplifiers. The precision NCS325 and NCS333 CMOS op-amps deliver zero drift operation and quiescent current for front-end amplifier circuits and power management designs.NCS325-333-Hires

The op-amp devices enhance the accuracy of motor control feedback and power supply control loops, thereby contributing to higher overall system efficiency. These devices are complemented by the new NCV333 automotive-qualified (AEC-Q100 grade 1) op-amp offering similar functional performance for power train, braking, electronic power steering, valve controls, and fuel pump and fuel injection system applications.

Features include:

  • High DC precision parameters, such as the 10 µV maximum input offset voltage at ambient temperature and the 30 nV/°C of offset temperature drift
  • Minimal voltage variations over temperature along with close to zero offset
  • Rail-to-rail input and output performance and are optimized for low voltage operation of 1.8 volt (V) to 5.5 V, with a best in class quiescent currents of 21 µA and 17 µA respectively at 3.3 V.
  • Operate with a gain bandwidth of 350 kHz with ultra-low peak-to-peak noise down to 1.1 µV from 0.1 Hz to 10 Hz.

The NCS325 is available in a 3 mm × 1.5 mm five-pin TSOP package. It costs $0.35 per unit in 3,000-unit quantities.

The NCS333 comes in a 1.5 mm × 3 mm SOT23-5 package or in a 2 mm × 1.25 mm SC70-5. It costs $0.5 per unit in 3,000-unit quantities.
