The AD5545-KGD is a 16-bit, current output, digital-to-analog
converter (DAC) designed to operate from a 4.5 V to 5.5 V supply
An external reference is needed to establish the full-scale output
current. An internal feedback resistor (RFB) enhances the resistance
and temperature tracking when combined with an external
op amp to complete the current to voltage (I to V) conversion.
A serial data interface offers high speed, 3-wire microcontroller
compatible inputs using serial data input (SDI), clock (CLK),
and chip select (CS). The LDAC function allows simultaneous
update operation. The internal reset logic allows power-on reset
and dynamic reset at either zero or midscale, depending on the
state of the MSB pin.
The AD5545-KGD is packaged in a 23-pad bare die package
and can be operated from −40°C to +85°C.
Known Good Die (KGD): these die are fully guaranteed to data
Additional application and technical information can be found
in the AD5545 data sheet.
