Software tools are readily available to simplify filter design. The WEBENCH® Filter Designer is a simple,
powerful, and easy-to-use active filter design program. The WEBENCH® Filter Designer lets you create
optimized filter designs using a selection of TI operational amplifiers and passive components from TI's vendor
partners.
Available as a web based tool from the WEBENCH Design Center, the WEBENCH Filter Designer allows you to
design, optimize, and simulate complete multistage active filter solutions within minutes.

9 Power Supply Recommendations
The OPAx140 is specified for operation from 4.5 V to 36 V (±2.25 V to ±18 V); many specifications apply from
–40°C to 125°C. Parameters that can exhibit significant variance with regard to operating voltage or temperature
are presented in Section 6.8.
CAUTION
Supply voltages larger than 40 V can permanently damage the device; see Section 6.1.
Place 0.1-μF bypass capacitors close to the power-supply pins to reduce errors coupling in from noisy or
high-impedance power supplies. For more detailed information on bypass capacitor placement, see Section 10.
