BP-DAC81404EVM, BP-DAC61402EVM
1 Overview
The BP-DAC81404EVM, BP-DAC61402EVM are an easy-to-use platform to evaluate the functionality and
performance of the DAC81404 device. The 16-bit DAC81404 (quad-channel) and 12-bit DAC61402 (dual-
channel) (DACx140x) are a pin-compatible family of buffered output (up to ±20 V) digital-to-analog
converters (DACs) with integrated 2.5-V internal reference. These devices are specified monotonic by
design and offer excellent linearity of less than 1 LSB. Additionally, the DACx140x implements per
channel sense pins to eliminate IR drop and to sense up to ±12 V of ground bounce.
The DACx140x includes reliability features such as CRC error check, short circuit protection, and thermal
alarm. These devices are characterized for operation over the temperature range of –40ºC to 125ºC and
are available in a very small 32-pin QFN package. The performance and feature set combined with a
small package make the DACx140x an excellent choice for end equipment such as automated test
equipment, analog output modules, servo motor drives, and precision data acquisition cards.
The DACx140x devices incorporate a power-on-reset circuit that ensures the DAC output powers in
power-down mode and remains in this mode until the outputs are enabled.
The device communicates through speed 4-wire serial interface (SPI) that supports operation from 1.7 V
to 5.5 V.
The EVM provides the GPIO and SPI programming interface using a PC-based graphical user interface
(GUI). This EVM requires the MSP-EXP432E401Y LaunchPad™ for interfacing with the PC-based GUI.
