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.

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 CLR input sets the output to zero scale at power on or upon user demand.
The AD8300 is specified over the extended industrial (–40°C to +85°C) temperature range.
AD8300s are available in plastic DIP, and low profile 1.
