GENERAL DESCRIPTION
The AD8300 is a complete 12-bit, voltage-output digital-to-
analog converter designed to operate from a single +3 volt sup-
ply. 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 oper-
ated 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.
A double buffered serial data interface offers high speed, three-
wire, 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. AD8300’s are available in plastic
DIP, and low profile 1.5 mm height SO-8 surface mount
packages.
