MAX5132/MAX5133 19-1441 Rev 0 3/99 +5V/+3V, 13-Bit, Serial, Force/Sense DACs with 10ppm/C Internal Reference General Description Features The MAX5132/MAX5133 low-power, 13-bit, voltage-out- Single-Supply Operation put digital-to-analog converters (DACs) feature an inter- +5V (MAX5132) nal precision bandgap reference and output amplifier. +3V (MAX5133) The MAX5132 operates on a single +5V supply with an Built-In 10ppm/C max Precision Bandgap Reference internal reference of +2.5V and offers a configurable out- +2.5V (MAX5132) put amplifier. If necessary, the user can override the on- chip, <10ppm/C voltage reference with an external +1.25V (MAX5133) reference. The MAX5133 has the same features as the SPI/QSPI/MICROWIRE-Compatible, 3-Wire Serial MAX5132 but operates from a single +3V supply and Interface has an internal +1.25V precision reference. The user- accessible inverting input and output of the amplifier Pin-Programmable Shutdown-Mode and Power- allows specific gain configurations, remote sensing, and Up Reset (0V or Midscale Output Voltage) high output drive capability for a wide range of Buffered Output Capable of Driving 5k 100pF force/sense applications. Both devices draw only 500A of supply current, which reduces to 3A in power-down or 420mA Loads mode. In addition, their power-up reset feature allows for Space-Saving 16-Pin QSOP Package a user-selectable initial output state of either 0V or mid- scale and reduces output glitches during power-up. Pin-Compatible Upgrades for the 12-Bit MAX5122/MAX5123 The serial interface is compatible with SPI, QSPI, and MICROWIRE, which makes the MAX5132/ Pin-Compatible 14-Bit Upgrades Available MAX5133 suitable for cascading multiple devices. Each (MAX5171/MAX5173) DAC has a double-buffered input organized as an input register followed by a DAC register. A 16-bit shift register loads data into the input register. The DAC register may Ordering Information be updated independently or simultaneously with the input register. PIN- INL PART TEMP. RANGE Both devices are available in a 16-pin QSOP package PACKAGE (LSB) and are specified for the extended-industrial (-40C to MAX5132AEEE -40C to +85C 16 QSOP 0.5 +85C) operating temperature range.
