MAX7414CUA+

The MAX7414CUA+ is a 5th order low pass, switched capacitor filter in 8 pin µMAX package. This butterworth filters provides a maximally flat pass band response. It operates with a 100:1 clock to corner frequency ratio. The device draw only 1.2mA of supply current and allow corner frequencies from 1Hz to 15KHz, making it ideal for low power post-DAC filtering and anti-aliasing applications. Two clocking options are available on this device, 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 output level. It is used in DAC post filtering, air-bag electronics and CT2 base stations.

• Supply voltage range is 2.7V to 3.6V
• Operating temperature range from 0°C to 70°C
• Typical corner frequency range from 0.001KHz to 15KHz
• Clock to corner tempco of 10ppm/°C, typical internal oscillator frequency is 30KHz
• Typical supply current is 1.2mA (operating mode, no load)
• Typical shutdown current is 0.2µA
