NCS2001
0.9 V, Rail-to-Rail, Single
Operational Amplifier
The NCS2001 is an industry first sub-one volt operational amplifier
that features a rail-to-rail common mode input voltage range, along
with rail-to-rail output drive capability. This amplifier is guaranteed
to be fully operational down to 0.9 V, providing an ideal solution for
powering applications from a single cell Nickel Cadmium (NiCd) or
Nickel Metal Hydride (NiMH) battery. Additional features include no
output phase reversal with overdriven inputs, trimmed input offset
voltage of 0.5 mV, extremely low input bias current of 40 pA, and a
unity gain bandwidth of 1.4 MHz at 5.0 V. The tiny NCS2001 is the
ideal solution for small portable electronic applications and is
available in the space saving SOT23-5 and SC70-5 packages with
two industry standard pinouts.
