19-1848; Rev 0; 10/00 256-Tap SOT-PoT,
Low-Drift Digital Potentiometers in SOT23
Features
♦ Miniature 8-Pin SOT23 (3mm x 3mm)
♦ 256 Tap Positions
♦ Ultra-Low 0.1µA Supply Current
♦ Single-Supply Operation: +2.7V to +5.5V
♦ Low Ratiometric Temperature Coefficient:
5ppm/В°C
♦ Power-On Reset: Wiper Goes to Midscale
(Position 128)
♦ Glitchless Switching Between the Resistor Taps The MAX5400/MAX5401 serve well in applications
requiring digitally controlled resistors, including
adjustable voltage references and programmable gain
amplifiers (PGAs). A nominal end-to-end resistor temperature coefficient of 50ppm/В°C allows these parts to
be used as variable resistors in applications such as
low-tempco adjustable gain and other circuit configurations. ♦ 3-Wire SPI™-Interface Compatible
♦ 50kΩ/100kΩ Resistor Values Ordering Information Two resistance values are available: 50kΩ (MAX5400)
and 100kΩ (MAX5401). Each device is guaranteed over
the extended industrial temperature range (-40В°C to
+85В°C). TEMP.
