Schmartboard Active Filter
The SchmartBoard Active Filter (710-0013-01) is a versatile and efficient module designed for implementing active filtering in your electronic projects. This board allows you to easily create and test a variety of analog filter circuits using operational amplifiers (op-amps), resistors, and capacitors. Whether you're designing high-pass, low-pass, band-pass, or notch filters, the SchmartBoard Active Filter is the perfect tool for enhancing your signal processing applications.
Engineered for both hobbyists and engineers, this module offers a convenient way to experiment with active filter designs and integrate them into your prototypes. It simplifies the process of working with filtering circuits, making it easier to control the frequency response of your signals and improve the performance of your system.
Key Features:
The SchmartBoard Active Filter is the perfect tool for anyone looking to integrate active filtering into their electronic designs. Whether you're working on signal conditioning, audio enhancement, or other filtering applications, this module offers a simple, efficient solution for creating high-quality active filters.
Streamline your filter design process and achieve precise frequency response control with the SchmartBoard Active Filter.
Applications for the Active Filter Board include being used as an anti-aliasing filter for A/D conversion or as a reconstruction filter after D/A conversion.
The Active filter Board is configured as a two pole active filter followed by a third passive pole if desired. The op amp circuitry forms the two pole filter while the RC network at the output of the operational amplifier forms the third passive pole.
The operational amplifier used for this board is the Texas Instrument’s OPA172 whose main features make it very suitable for experimenting.
These features are,
• Wide Supply Range: +4.5 V to +36 V, ±2.25 V to ±18 V
• Low Offset Voltage: ±0.2 mV
• Gain Bandwidth: 10 MHz
• Input Range Includes the Negative Supply
• Input Range Operates to Positive Supply
• Rail-to-Rail Output
• Low Noise: 7 nV/√Hz
• High Common-Mode Rejection: 120 dB
• Low Input Bias Current: ±8 pA
• Low Quiescent Current: 1.6mA per Amplifier
The OPAMP Board can be operated with single or dual power supplies and the 10MHz bandwidth makes is sufficient for most experimenter’s circuits.

Schmartboards' also connect together. Schmartboard allows you to wire up multiple Schmartboard and then mechanically connect them via our "SchmartBridges". Schmartboard's "Electronic Circuit Building Block" patented technology makes it easier to create and trouble-shoot your circuit. Rather than trouble-shooting an issue on a large and complicated messy circuit, why not build and test smaller circuit blocks and then connect them together to form your larger final circuit. This saves time and money and is only available from Schmartboard.
