Typical Application


The TP2271/TP2272/TP2274 are EMI Hardened 36V CMOS op-amps featuring EMIRR of 84dB at 900MHz. The devices are unity gain stable with 100pF capacitive load and high-speed with a wide 7MHz bandwidth and 20V/μs high slew rate, which makes the devices appropriated for I/V converters. The rail-to-rail output swing and input range that includes V– makes the TP227x ideal choices for interfacing to modern, single-supply and precision data converters.

The TP227x 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 TP227x 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 TP2271 is single channel version available in 8-pin SOIC and 5-pin SOT23 packages. The TP2272 is dual channel version available in 8-pin SOIC and MSOP packages. The TP2274 is quad channel version available in 14-pin SOIC and TSSOP packages.
