Typical Application


The TP1251/TP1252/TP1254 are low power precision EMI Hardened 36V CMOS op-amps featuring EMIRR of 108dB at 1000MHz. These devices provide very low quiescent current which are very suitable for low power or battery power supply system.  The rail-to-rail output swing and input range that includes V– makes the TP125x ideal choices for interfacing to modern,single-supply and precision data converters.

The TP125x op-amps offer lower noise, offset voltage, offset drift over temperature and bias current. In addition, the devices have better common-mode rejection and slew rates.

The TP125x family,exhibiting high input impedance and low noise, is excellent for small signal conditioning for high impedance sources, such as piezoelectric transducers. Because of the micro power dissipation levels, the devices work well in hand held monitoring and remote sensing applications.

The TP1251 is single channel version available in8-pin SOIC and 5-pin SOT23 packages. The TP1252 is dual channel version available in 8-pin SOIC and MSOP packages. The TP1254 is quad channel version available in 14-pin SOIC and TSSOP packages.
