Built using a CBCMOS process, this monolithic DAC offers the user low cost, and ease-of-use in single-supply +3 volt systems. Operation is guaranteed over the supply voltage range of +2.7 V to +5.5 V making this device ideal for battery operated applications. The 2.0475 V full-scale voltage output is laser trimmed to maintain accuracy over the operating temperature range of the device. The binary input data format provides an easy-to-use one-half-millivolt-per-bit software programmability. The voltage outputs are capable of sourcing 5 mA. 3.0 MINIMUM SUPPLY VOLTAGE – Volts A double buffered serial data interface offers high speed, threewire, DSP and microcontroller compatible inputs using data in (SDI), clock (CLK) and load strobe (LD) pins. A chip select (CS) pin simplifies connection of multiple DAC packages by enabling the clock input when active low. Additionally, a...
