MAX5230, MAX5231 3V/5V, 12-Bit, Serial Voltage-Output Dual DACs With Internal ReferenceThe MAX5230 MAX5231 low-power, dual 12-bit voltage-output digital-to-analog converters (DACs) feature an internal 3ppm/C precision bandgap Voltage Reference and precision output Amplifiers The MAX5231 operates on a single 5V supply with an internal 2.5V reference and features a 4.095V full-scale output range. The MAX5230 operates on a single 3V supply with an internal 1.25V reference and features a 2.0475V full-scale output range. The MAX5231 consumes only 470A while the MAX5230 consumes only 420A of supply current. Both devices feature low-power (2A) software- and hardware-enabled shutdown modes.
The MAX5230 MAX5231 feature a 13.5MHz SPI-, QSPI-, and MICROWIRE-compatible 3-wire serial Interface An additional data output (DOUT) allows for daisy-chaining and read back. Each DAC has a double-buffered digital input. The MAX5230 MAX5231 feature two software-selectable shutdown output impedances: 1k or 200k. A power-up reset feature sets DAC outputs at ground or at the midscale DAC code. The MAX5230 MAX5231 are specified over the extended temperature range (-40C to +85C) and are available in 16-pin QSOP packages. By Maxim Integrated Products |
