Microprocessor Programmable  
Universal Active Filters  
General Description  
Features  
The MAX260/MAX261/MAX262 CMOS dual second-  
order universal switched-capacitor active filters allow  
microprocessor control of precise filter functions. No  
external components are required for a variety of band-  
pass, lowpass, highpass, notch, and allpass configura-  
tions. Each device contains two second-order filter  
sections that place center frequency, Q, and filter oper-  
ating mode under programmed control.  
o Filter Design Software Available  
o Microprocessor Interface  
o 64-Step Center Frequency Control  
o 128-Step Q Control  
o Independent Q and f Programming

determine the filter's center or corner frequency without  
affecting other filter parameters. The filter Q is also pro-  
grammed independently. Separate clock inputs for  
each filter section operate with either a crystal, RC net-  
work, or external clock generator.

o Single +5V and 5V ꢀperation  
Ordering Information  
The MAX260 has offset and DC specifications superior  
to the MAX261 and MAX262 and a center frequency  
(f ) range of 7.5kHz. The MAX261 handles center fre-  
0
quencies to 57kHz, while the MAX262 extends the cen-  
ter frequency range to 140kHz by employing lower  
clock-to-f ratios. All devices are available in 24-pin DIP
