Dual Universal Switched-Capacitor Filters

General Description

Features

The MAX7490/MAX7491 consist of two identical low-

power, low-voltage, wide dynamic range, Rail-to-Rail^®,

2nd-order switched-capacitor building blocks. Each of

the two filter sections, together with two to four external

resistors, can generate all standard 2nd-order func-

tions: bandpass, lowpass, highpass, and notch (band

reject). Three of these functions are simultaneously

available. Fourth-order filters can be obtained by cas-

cading the two 2nd-order filter sections. Similarly, high-

er order filters can easily be created by cascading

multiple MAX7490/MAX7491s.

ꢀ Dual 2nd-Order Filter in a 16-Pin QSOP Package

ꢀ High Accuracy

Q Accuracy: ±±02ꢀ

Clock-to-Center Frequency Error: ±±02ꢀ

ꢀ Rail-to-Rail Input and Output Operation

ꢀ Single-Supply Operation: +5V (MAX749±)

or +3V (MAX7491)

ꢀ Internal or External Clock

ꢀ Highpass, Lowpass, Bandpass, and Notch Filters

ꢀ Clock-to-Center Frequency Ratio of 1±±:1

Two clocking options are available: self-clocking

(through the use of an external capacitor) or external

clocking for tighter cutoff frequency control. The clock-

to-center frequency ratio is 100:1. Sampling is done at

twice the clock frequency, further separating the cutoff

frequency and Nyquist frequency.

ꢀ Internal Sampling-to-Center Frequency Ratio

of 2±±:1

ꢀ Center Frequency up to 4±kHz

The MAX7490/MAX7491 have an internal rail splitter

that establishes a precise common voltage needed for

single-supply operation. The MAX7490 operates from a

single +5V supply and the MAX7491 operates from a

single +3V supply. Both devices feature a low-power

shutdown mode and come in a 16-pin QSOP package.

ꢀ Easily Cascaded for Multipole Filters

ꢀ Low-Power Shutdown: <1µA Supply Current
