The TP212x are ultra-low power, precision CMOS
op-amps featuring a maximum supply current of
950nA per amplifier with an ultra-low typical input
bias current of 1fA. Analog trim and calibration
routine reduce input offset voltage to below 1.5mV,
and the precision temperature compensation
technique makes offset voltage temperature drift at
0.5μV/°C, which allowing use of the TP212x in
systems with high gain without creating excessively
large output offset errors.
The TP212x are unity gain stable with 1,000nF
capacitive load with a constant 18kHz GBWP,
10mV/μs slew rate, which make them appropriate
for low frequency applications, such as battery
current monitoring and sensor conditioning. The
TP212x can operate from a single-supply voltage of
+1.8V to +6.0V or a dual-supply voltage of ±0.9V to
±3.0V. Beyond the rails input and rail-to-rail output
characteristics allow the full power-supply voltage to
be used for signal range.
The combined features make the TP212x ideal
choices for battery-powered applications because
they minimize errors due to power supply voltage
variations over the lifetime of the battery and
maintain high CMRR even for a rail-to-rail input
op-amp. Mobile accessories, wireless remote
sensing, backup battery sensors, and single-Li+ or
2-cell NiCd/Alkaline battery powered systems can
benefit from the features of the TP212x op-amps.
For applications that require power-down, the
TP2121N has a low-power shutdown mode that
reduces supply current to 3nA, and forces the output
into a high-impedance state.
