ON Semiconductor Unveils New Family of Ultra-Low Power Pre
Source: onsemi
ON Semiconductor (Nasdaq: ONNN), driving energy efficiency innovations, has introduced a family of affordable, precision CMOS operational amplifiers (op amps) that deliver zero drift operation and industry leading quiescent current for front-end amplifier circuits and power management designs. Targeted at industrial, white goods, telecom, wearables, Internet-of-Things (IoT), test equipment and instrumentation applications, the NCS325 and NCS333 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, fuel pump and fuel injection system applications.
Featuring high DC precision parameters, such as the 10 micro Volts (µV) maximum input offset voltage at ambient temperature and the 30 nV/°C of offset temperature drift, make these amplifier devices extremely well optimized for low side current sensing and voltage differential measurement on front-end sensor functions. Minimal voltage variations over temperature along with close to zero offset ensure the efficiency of systems exposed to wide operating temperature ranges without the need for complex software calibration algorithms, resulting in a more manageable design and longer product lifespan.
The NCS325 and NCS333 provide 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. The devices operate with a gain bandwidth of 350 kilohertz (kHz) with ultra-low peak to peak noise down to 1.1 µV from 0.1 Hertz (Hz) to 10 Hz.
“By offering precision operational amplifiers that deliver industry-leading analog performance, these new devices meet the stringent objectives of our customer’s projects as well as addressing the ever growing industry demand for more energy efficient end designs,” said Simon Keeton, vice president Integrated Circuit Products at ON Semiconductor. “Historically, engineers have preferred to utilize zero drift precision op-amps but the traditionally high cost of such solutions has discouraged implementation. With the introduction of this family of amplifiers, we have been able to make precision affordable.”
Pricing and Packaging
The NCS325 is offered in a 3 mm x 1.5 mm 5-pin TSOP package. It has unit pricing of $0.35 in 3,000 unit quantities. The NCS333 is offered in a 1.5 mm x 3 mm SOT23-5 package or in a 2mm x 1.25mm SC70-5 and has unit pricing of $0.5, in 3,000 unit quantities.
