The MAX7401/MAX7405 8th-order, lowpass, Bessel,

switched-capacitor filters (SCFs) operate from a single

+5V (MAX7401) or +3V (MAX7405) s up p ly. The s e

devices draw only 2mA of supply current and allow cor-

ner frequencies from 1Hz to 5kHz, making them ideal

for low-power post-DAC filtering and anti-aliasing appli-

cations. They feature a shutdown mode that reduces

supply current to 0.2µA.

♦ 8th-Order, Lowpass Bessel Filters

♦ Low Noise and Distortion: -82dB THD + Noise

♦ Clock-Tunable Corner Frequency (1Hz to 5kHz)

♦ 100:1 Clock-to-Corner Ratio

♦ Single-Supply Operation

+5V (MAX7401)

Two clocking options are available on these devices:

self-clocking (through the use of an external capacitor)

or external clocking for tighter corner-frequency control.

An offset adjust pin allows for adjustment of the DC out-

put level.

+3V (MAX7405)

♦ Low Power

2mA (Operating Mode)

0.2µA (Shutdown Mode)

The MAX7401/MAX7405 Bessel filters provide low over-

shoot and fast settling. Their fixed response simplifies

the design task to selecting a clock frequency.

♦ Available in 8-Pin SO/DIP Packages

♦ Low Output Offset: ±5mV
