NOTES
1Typical readings represent the average value of room temperature operation.
21 LSB = 0.5 mV for 0 V to +2.0475 V output range. The first two codes (000 H, 001H) are excluded from the linearity error measurement.
3Includes internal voltage reference error.
4These parameters are guaranteed by design and not subject to production testing.
5All input control signals are specified with tR = tF = 2 ns (10% to 90% of +5 V) and timed from a voltage level of 1.6 V.
6The settling time specification does not apply for negative going transitions within the last 6 LSBs of ground.
7See Figure 6 for a plot of incremental supply current consumption as a function of the digital input voltage levels.
Specifications subject to change without notice.

GENERAL DESCRIPTION
The AD8303 is a complete (includes internal reference) dual,12-bit, voltage output digital-to-analog converter designed to operate from a single +3 volt supply. Built using a CBCMOSprocess, 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 3 mA.
