The MAX7400ESA from Maxim Integrated is a highly sophisticated 8th-order lowpass elliptic switched-capacitor filter that significantly reduces the complexity of signal conditioning in digital communication systems. Engineered with precision, this compact component is housed in an 8-pin SO package, making it a space-saving solution for a myriad of applications.

Key Features

• Filter Type: The MAX7400ESA implements an 8th-order elliptic lowpass response which is known for its steep roll-off characteristics and ripple in the passband.
• Operating Frequency: It operates with a clock frequency range of 10kHz to 105kHz, providing a versatile solution for various design requirements.
• Low Power Consumption: With a low operating current of just 2.0mA and a power-down feature that reduces current consumption to 0.2µA, this filter is an excellent choice for power-sensitive applications.
• Single-Supply Operation: The device can be powered by a single +5V supply, simplifying power management in embedded systems.
• No External Components Required: This switched-capacitor filter does not require any external components for filter operation, although external clock and capacitors can be used to adjust the corner frequency.

Applications

The MAX7400ESA is suitable for a wide range of applications, including but not limited to:

• Anti-aliasing for data acquisition systems
• Post-DAC filtering for digital audio
• Signal conditioning in telecommunications
• CT2 base stations
