MAX7412CPA

Overview

The MAX7412CPA is a fifth-order, lowpass, elliptic switched-capacitor filter manufactured by Analog Devices under the Maxim Integrated brand. It operates on a single supply voltage ranging from 2.7V to 3.6V and features a clock-tunable corner frequency adjustable between 1Hz and 15kHz. The device is housed in an 8-pin PDIP package with through-hole mounting capabilities. Designed for low noise and distortion performance, it achieves a total harmonic distortion plus noise level of -80dB. The component functions as a standalone active filter suitable for precision signal conditioning applications within its specified electrical limits.

Feature Summary

• Fifth-order elliptic lowpass filtering characteristic
• Clock-tunable corner frequency capability
• Low noise and distortion performance

Applications

• Precision signal conditioning circuits
• Audio processing systems requiring low distortion
• Sensor interface front-ends

Part Context

The MAX7412 belongs to the MAX74xx series of switched-capacitor filters from Maxim Integrated. This family provides versatile analog filtering solutions using external clock signals to define cutoff frequencies. The CP suffix indicates a commercial temperature range variant packaged in standard plastic dual in-line format, distinguishing it from industrial or military grade options within the same product line.

Replacement Considerations

Verify pin compatibility and switching capacitor architecture requirements when substituting. Ensure the replacement supports the specific 1Hz to 15kHz tuning range and single-supply operation constraints of the original design.
