Typical Application

The TP127x in DAC I/V Amplifier and Low-Pass Filter Applications


The TP1271/TP1272/TP1274 series are Precision EMI  Hardened, high-voltage CMOS op-amps featuring  EMIRR of 84dB at 900MHz. TP127X series op amps  could operate from ±1.35V to ±18V supplies with excellent performance, They offer very low offset voltage and drift, low bias current, high common-mode  rejection, and high power supply rejection. 

The TP127X are unity gain stable with 100pF capacitive load with a wide 7MHz bandwidth, 20V/μs high slew rate, which makes the device appropriate for I/V converters.

These op amps are ideal for various applications, including process control, industrial and instrumentation equipment, active filtering, data conversion, buffering,  and power control and monitoring. Additionally, the TP127X is EMI hardened to minimize any interference, so they are ideal for EMI sensitive application. 

The TP1271 is single channel version available in 8-pin SOIC and 5-pin SOT23 package. The TP1272 is dual channel version available in 8-pin SOIC and MSOP  package. The TP1274 is quad channel version available in 14-pin SOIC and TSSOP package.
