The TP2311 series products are very high precision
amplifiers featuring very low noise, low offset voltage,
high bandwidth, low input bias current and low
temperature drift making them the ideal choice for
applications requiring both high DC accuracy and AC
performance. The combination of precision, low noise,
and high bandwidth provides the user with outstanding
value and flexibility relative to similar competitive parts.
Applications for these amplifiers include precision active
filters, medical and analytical instrumentation, precision
power supply controls, and industrial controls requiring
high gains. Featuring low THD+N, the TP2311 series is
also excellent for consumer audio applications,
particularly for single-supply systems.
The TP2311 is single channel version available in 8-pin
SOIC and 5-pin SOT23 packages. The TP2312 is dual
channel version available in 8-pin SOIC, SOT and
MSOP packages. The TP2314 is quad channel version
available in 14-pin SOIC and TSSOP packages.

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 op amp supplies must be established simultaneously, with, or before, the application of any input signals.
Note 3:
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 4:
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.
