New zero drift, low voltage devices highly
suited to precision applications in industrial, consumer, wireless,
IoT and automotive where strong stability across wide operating
temperature ranges is mandated
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 customers' 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.
