Introduction

widtꢂꢀ Tꢂe N/ꢁP/AP outputs of tꢂe MAX260 are internal-

ly sample-and-ꢂeld as a result of its auto-Hero

operationꢀ Signal swing at tꢂis output is somewꢂat

reduced as a result (MAX260 only)ꢀ See Table 1 for

bandwidtꢂ comparisons of tꢂe tꢂree filtersꢀ

Eacꢂ MAX260/MAX261/MAX262 contains two second-

order switcꢂed-capacitor active filtersꢀ Figure 1 sꢂows

tꢂe filter's state variable topology, employed witꢂ two

cascaded integrators and one summing amplifierꢀ Tꢂe

MAX261 and MAX262 also contain an uncommitted

amplifierꢀ On-cꢂip switcꢂes and capacitors provide

Maxim also provides design programs tꢂat aid in con-

verting filter response specifications into tꢂe f and Q

feedback to-control eacꢂ filter section's f and Qꢀ

program codes used by tꢂe MAX260 series devicesꢀ

Internal capacitor ratios are primarily responsible for

tꢂe accuracy of tꢂese parametersꢀ Altꢂougꢂ tꢂese

switcꢂed-capacitor networks (SCN) are in fact sampled

systems, tꢂeir beꢂavior very closely matcꢂes tꢂat of

continuous filters, sucꢂ as RC active filtersꢀ Tꢂe ratio of

tꢂe clock frequency to tꢂe filter center frequency

Tꢂis software also precompensates f and Q wꢂen low

sample rates are usedꢀ

It is important to note tꢂat, in all MAX260 series filters,

tꢂe filter's internal sample rate is one ꢂalf tꢂe input

clock rate (CLK or CLK ) due to an internal division

/f ) is kept large so tꢂat ideal second-order state-

CLK 0

cussions in tꢂis data sꢂeet refer to tꢂe frequency at tꢂe

variable response is maintainedꢀ

Quick Look Design Procedure

reduced sample rates result in somewꢂat more devia-

tion from ideal continuous filter parameters tꢂan witꢂ

tꢂe MAX260/MAX261ꢀ ꢁowever, tꢂese differences can

be compensated using Figure 20 (see Application

Hints) or Maxim's filter design softwareꢀ

Tꢂe MAX260, MAX261, and MAX262, witꢂ Maxim's filter

design software, greatly simplify tꢂe design procedures

for many active filtersꢀ Most designs can be realiHed

using a tꢂree-step process described in tꢂis sectionꢀ If

tꢂe design software is not used, or if tꢂe filter complexi-

ty is beyond tꢂe scope of tꢂis section, refer to tꢂe

remainder of tꢂis data sꢂeet for more detailed applica-

tions and design informationꢀ

Tꢂe MAX260 employs auto-Hero circuitry not included

in tꢂe MAX261 or MAX262ꢀ Tꢂis provides improved DC

cꢂaracteristics, and improved low-frequency perform-
