Typical Application


The TP2271/TP2272/TP2274 areEMI Hardened 36V CMOS op-amps featuring EMIRR of 84dB at 900MHz. The devicesare unity gain stable with 100pF capacitive load and high-speed with a wide7MHz bandwidth and 20V/μs high slew rate, which makes the devices appropriatedfor I/V converters.

The rail-to-rail outputswing and input range that includes V– makes the TP227x ideal choices for interfacingto modern, single-supply and precision data converters.

The TP227x op-amps offerlower noise, offset voltage, offset drift over temperature and bias current. Inaddition, the devices have better common-mode rejection and slew rates.

The TP227x family,exhibiting high input impedance and low noise, is excellent for small signalconditioning for high impedance sources, such as piezoelectric transducers.Because of the micro power dissipation levels, the devices work well in handheld monitoring and remote sensing applications.

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