NCS2002SN2T1G

Instrumentation, Op Amps, Buffer Amps Overview

The NCS2002SN2T1G is a single operational amplifier featuring rail-to-rail input and output capabilities, guaranteed to operate at supply voltages as low as 0.9 V. It incorporates an active-high enable pin for external shutdown control, reducing standby current to typically 1.9 nA at 1.0 V. The device utilizes an N-channel depletion mode MOSFET input stage, providing an extremely low input bias current of 10 pA and no output phase reversal under overdriven conditions. It offers a unity gain bandwidth of 1.1 MHz at ±2.5 V and is housed in a space-saving SOT23-6 (TSOP-6) package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix SN2T1G against the official onsemi datasheet to confirm the correct pinout style and shipping configuration. Confirm that the component meets RoHS compliance standards and Pb-Free requirements as specified in the documentation. Ensure the selected variant aligns with the required operating temperature range and automotive qualification needs if applicable.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring operation from a single cell battery source below one volt. The device is suitable for portable electronics where low power consumption and small footprint are critical. Consider the enable feature for power management strategies. Verify compatibility with the required signal bandwidth and capacitive load driving capabilities within the specified supply voltage range.

Instrumentation, Op Amps, Buffer Amps Part Context

The NCS2002 belongs to a family of sub-one volt rail-to-rail operational amplifiers manufactured by onsemi. It is designed using a modified analog CMOS process that implements depletion MOSFET devices. This technology enables the unique combination of sub-volt operation, rail-to-rail performance, and extremely low input bias currents not commonly found in standard bipolar op-amps.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Check for discontinued variants such as NCS2002SN1T1G which share similar electrical characteristics but may differ in pinout style. Consult the manufacturer's discontinuation notice for updated availability and potential cross-reference recommendations for current production versions.

Instrumentation, Op Amps, Buffer Amps FAQ

What happens if the input common mode voltage exceeds the supply rails?

The NCS2002 does not exhibit output phase reversal when the input common mode voltage is exceeded, ensuring stable operation even with overdriven input signals.

How is the device disabled?

The amplifier is disabled when the enable pin voltage is pulled below the input disable threshold, which is approximately 45% of the supply voltage (VCC).

Can the NCS2002 drive large capacitive loads directly?

It can drive capacitive loads up to 820 pF in a unity gain follower configuration without oscillating. For larger capacitive loads, an isolation resistor between the output and the load is recommended to maintain stability.
