MaximMAX 292CPA

The Maxim Integrated MAX292CPA 8th-Order Bessel Low-Pass Switched-Capacitor Filter 0.1Hz-25kHz DIP-8 is an 8th-order Bessel low-pass switched-capacitor filter with clock-tunable cutoff frequency and a maximum corner frequency of 25kHz.

Technical description

The MAX292 provides a Bessel response for low overshoot and fast settling. Corner frequency is clock-tunable from 0.1Hz to 25kHz with a 100:1 clock-to-corner ratio and can use either an internal or external clock. No external resistors or capacitors are required for the filter function. It also includes an uncommitted op amp for anti-aliasing or clock-noise filtering. The family operates from a +5V single supply or +/-5V dual supplies, with specified supply limits of 4.75-11V single supply or +/-2.375 to +/-5.5V dual supplies.

Indicative applications

Suitable for anti-aliasing, signal conditioning, audio/measurement filters, data acquisition, instrumentation, communication systems and precision low-pass filtering.

Compatibility note

MAX292 is a Bessel filter with a 100:1 clock ratio. It is not functionally identical to the MAX291, which is Butterworth, or to MAX295/MAX296 devices using a 50:1 ratio and up to 50kHz. The CPA version is the commercial-temperature PDIP-8 package.
