MAX5232, MAX5233
3V/5V, 10-Bit, Serial Voltage-Output Dual DACs with Internal Reference
|
Status
Active: In Production.
Description
The MAX5232/MAX5233 low-power, dual 10-bit voltage-output digital-to-analog converters (DACs) feature an internal 10ppm/°C precision bandgap voltage reference and precision output amplifiers. The MAX5233 operates on a single 5V supply with an internal 2.465V reference and features a 4.092V full-scale output range. The MAX5232 operates on a single 3V supply with an internal 1.234V reference and features a 2.046V full-scale output range. The MAX5233 consumes only 470µA while the MAX5232 consumes only 420µA of supply current. Both devices feature low-power (2µA) software- and hardware-enabled shutdown modes.
The MAX5232/MAX5233 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 MAX5232/MAX5233 feature two software-selectable shutdown output impedances: 1kΩ or 200kΩ. A power-up reset feature sets DAC outputs at ground or at the midscale DAC code.
The MAX5232/MAX5233 are specified over the extended temperature range (-40°C to +85°C) and are available in 16-pin QSOP packages.
