Features
Description
TP151x series are CMOS single/dual/quad op-amps
with low offset, stable high frequency response, low
power, low supply voltage, and rail-to-rail inputs and
outputs. They incorporate 3PEAK’s proprietary and
patented design techniques to achieve best in-class
performance among all micro-power CMOS
amplifiers in its power class. The TP151x family can
be used as plug-in replacements for many
commercially available op-amps to reduce power
and improve input/output range and performance.
TP151x are unity gain stable with Any Capacitive
load with a constant 150kHz GBWP, 0.09V/μs slew
rate while consuming only 4μA of quiescent current
per amplifier. Analog trim and calibration routine
reduce input offset voltage to below 3.0mV, and
proprietary precision temperature compensation
technique makes offset voltage temperature drift at
0.6μV/° Beyond the rails input and rail-to-rail
C.
output characteristics allow the full power-supply
voltage to be used for signal range.
This combination of features makes the TP151x
OPA 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. Battery Current Monitor, consumer devices,
handheld instrumentation, Remote battery-powered
sensors, hazard detection (for example, smoke, fire,
and gas), and patient monitors can benefit from the
features of the TP151x op-amps.
For applications that require power-down, the
TP1511N in popular type packages has a low-power
shutdown mode that reduces supply current to less
than 0.1μA, and forces the output into a
high-impedance state.

Note 1:
Stresses beyond those listed under Absolute Maximum Ratings may cause permanent damage to the device. Exposure to any
Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime.
Note 2:
The inputs are protected by ESD protection diodes to each power supply. If the input extends more than 500mV beyond the power
supply, the input current should be limited to less than 10mA.
Note 3:
A heat sink may be required to keep the junction temperature below the absolute maximum. This depends on the power supply
voltage and how many amplifiers are shorted. Thermal resistance varies with the amount of PC board metal connected to the package. The
specified values are for short traces connected to the leads.
