max6220 low-noise, pr ecision, +2.5v/+4.096v/+5v v oltage refer ence 8 _ _ _ ____________________________________________________________________________________ detailed description temperature stability the max6220 is a highly stable, low-noise voltage ref- erence that uses a low-power temperature-compensa- tion scheme to achieve laboratory-standard temper- ature stability. this produces a nearly flat temperature curve, yet does not require the power associated with heated references. the output voltage can be trimmed 0.6% (min) by con- necting a 10k ? potentiometer between out and gnd, and connecting its tap to the trim pin (figure 1). the external trimming does not affect temperature stability. noise reduction to augment wideband noise reduction, add a 1f capacitor to the nr pin (figure 2). larger values do not improve noise appreciably ( see typical operating characteristics ). noise in the power-supply input can affect output noise, but can be reduced by adding an optional bypass capacitor to the in pin and gnd. bypassing the max6220 is stable with capacitive load values from 0f to 100f, for all values of load current. adding an output bypass capacitor can help reduce noise and output glitching caused by load transients. applications information negative regulator figure 3 shows how both a +5v and -5v precision ref- erence can be obtained from a single unregulated +5v supply. the max865 generates approximately 9v to operate both the max6220 reference and the max480 inverting amplifier. the +5v is inverted by the max480. resistor r1 is optional, and may be used to trim the 5v references. r2 and r4 should be matched, both in absolute resistance and temperature coefficient. r3 is optional, and is adjusted to set the -5v reference. _____________________pin description name function 1, 7, 8 i.c. internally connected. do not use . 2 in positive power-supply input pin 4 gnd ground 3 nr noise reduction. optional capacitor connection for wideband noise reduction. leave open if not used (figure 2). 6 out voltage reference output 5 trim external trim input. allows 1% output adjustment (figure 1). leave open if not used. max6220 in 8v to 40v input reference out out trim 10k ? nr gnd max6220 in 8v to 40v input reference out out trim nr *optional 1 f gnd 2.2 f* figure 1. output voltage adjustment figure 2. noise-reduction capacitor
