Overview
The MAX7407EPA+ is an 8th-order, lowpass, elliptic switched-capacitor filter (SCF) designed for single +3V supply operation. It provides a sharp rolloff with a transition ratio of 1.2 and typical stopband rejection of 60dB. The corner frequency is tunable from 0.001kHz to 10kHz via a 100:1 clock-to-corner ratio using either an external clock or an internal oscillator set by an external capacitor. Key electrical parameters include a typical supply current of 2mA in operating mode and 0.2µA in shutdown mode. The device features a low output offset voltage of ±5mV and operates within a temperature range of -40°C to +85°C.

Procurement Notes
Verify the component authenticity through official Analog Devices channels or authorized distributors. Confirm that the specific ordering suffix matches the required package type and temperature range specifications. Ensure compliance with relevant environmental standards before integration into final designs.
Selection Notes
Select the MAX7407EPA+ when a +3V single-supply system requires high-order filtering with steep rolloff characteristics. This component is suitable for applications needing precise corner frequency control via clock signals. Consider the 100:1 clock-to-corner ratio for flexible design options.
Part Context
This part belongs to the MAX7400/MAX7403/MAX7404/MAX7407 family of 8th-order, lowpass, elliptic, switched-capacitor filters. The MAX7407 variant specifically supports +3V operation and offers a transition ratio of 1.2. Other family members support +5V supplies or different transition ratios.
Replacement Considerations
Direct pin-compatible replacements within the same family include MAX7400EPA+, MAX7403EPA+, and MAX7404EPA+. Note that these alternatives operate at +5V or have different transition ratios, requiring circuit adjustments.
