Detailed Description
MAX4539/MAX4540 multiplexers with additional calibration features. Internal resistor-dividers generate accurate voltage ratios from external voltage reference, allowing zero- full-scale calibration systems well facilitation system self-monitoring. access resistor-dividers, assert pin. When ENABLE asserted, three address pins select various resistor-divider external reference outputs. MAX4539/MAX4540 also contain LATCH input that allows state address signals captured. biased either analog signal. This means their leakage varies signal varies. difference two-diode leakage from signal path pins constitutes analogsignal path leakage current. analog-leakage current flows supply terminals, other switch terminal, which explains both sides given switch show leakage currents either same opposite polarity. There connection between analog-signal paths GND. analog-signal paths consist N-channel P-channel MOSFET with their sources drains paralleled their gates driven phase with logic-level translators. power internal logic logic-level translators input-logic thresholds. logiclevel translators convert logic levels switched signals drive gates analog switches. This drive signal only connection between logic supplies analog supplies. pins have protection Increasing effect logic-level thresholds, does increase drive P-channel switches, which reduces their on-resistance. also sets negative limit analog-signal voltage. logic-level thresholds CMOS- TTL- compatible when +5V. raised, threshold increases slightly; when reaches +12V, level threshold about 3.2V. Although that above output high-level minimum 2.4V, still compatible with CMOS outputs.
Calibration Functions
Gain Divider, Offset Divider, REFHI REFLO modes allow calibration offset gain errors systems. Gain Divider mode outputs voltage ratio that 4081/4096 VREFHI VREFLO, accurate 0.1/4096, better than bits. Offset Divider mode outputs voltage ratio that 15/4096 VREFHI VREFLO, also accurate 0.1/4096. REFHI mode allows voltage REFHI switched output. REFLO mode allows voltage REFLO switched output.
Self-Monitoring Functions
self-monitoring functions intended allow measure supply voltage. MAX4539 internal divide-by-two resistor string between that accurate bits (16/4096). also resistor string between that also accurate bits. This divider string allows measurement negative supply with unipolar ADC. also switched output, eliminating need additional multiplexer channel.
Bipolar-Supply Operation
MAX4539/MAX4540 operate with bipolar supplies between ±2.7V ±6V. supplies need symmetrical, their cannot exceed absolute maximum rating 13V. Note: connect MAX4539/MAX4540 connect logic-level input pins logic-level signals. logic-level outputs exceed absolute maximum ratings, which will cause damage part and/or external circuits. Caution: absolute maximum differential voltage 13V. Typical "±6-Volt" "12-Volt" supplies with ±10% tolerances high 13.2V. This voltage damage MAX4539/MAX4540. Even tolerance supplies have overshoot noise spikes that exceed 13V.
Applications Information
MAX4539/MAX4540's construction typical most CMOS analog switches. There three supply pins: GND. positive negative power supplies provide drive internal CMOS switches limits analog voltage switch. Reverse-biased protection diodes internally connected between each analog signal both voltage exceeds these diodes will conduct. During normal operation, these reverse-biased diodes leak, forming only current drawn from Virtually analog-leakage current through diodes. Although diodes given signal identical, therefore fairly well balanced, they reverse-biased differently. Each

Single-Supply Operation
MAX4539/MAX4540 operate from single supply between +2.7V +12V when connected GND. bipolar precautions must observed. However, these parts optimized operation, most characteristics degraded significantly when departing from ±5V. overall supply voltage lowered, switching speed, on-resistance, isolation, distortion will degrade. (see Typical Operating Characteristics section). Single-supply operation also limits signal levels interferes with ground referenced signals. When signals limited -0.3V. Voltages below -0.3V clipped internal ESD-protection diodes, parts damaged excessive current flows. internal dividers connected between supplies inadvertently turn causing higher supply current (~200µA supply current) when enable input toggled. Avoid this condition ensuring that stays until remaining logic inputs valid. accomplish this, connect resistor from ground apply voltage before other logic inputs high.
