Overview
The NCS2002SN1T1G, produced by onsemi, is an innovative sub-one volt rail-to-rail operational amplifier. This device is notable for its ability to operate fully at voltages as low as 0.9 V, making it ideal for applications powered by a single cell Nickel Cadmium (NiCd) or Nickel Metal Hydride (NiMH) battery. The NCS2002 features a rail-to-rail common mode input voltage range and rail-to-rail output drive capability, ensuring robust performance across a wide range of input and output conditions.
The amplifier includes an active high enable pin for external shutdown, reducing the supply current to typically 1.9 µA at 1.0 V in standby mode. Its small size and enable feature make it particularly suited for small portable electronic applications. The device is available in the space-saving SOT23-6 (TSOP-6) package.
