GENERAL DESCRIPTION
The AD5551 and AD5552 are single, 14-bit, serial input, voltage
output DACs that operate from a single 5 V ± 10% supply.
The AD5551 and AD5552 utilize a versatile 3-wire interface that
is compatible with SPI, QSPI, MICROWIRE, and DSP inter-
face standards.
These DACs provide 14-bit performance without any adjust-
ments. The DAC output is unbuffered, which reduces power
consumption and offset errors contributed by an output buffer.
With an external op amp the AD5552 can be operated in bipo-
lar mode generating a ± V
includes Kelvin sense connections for the reference and analog
ground pins to reduce layout sensitivity. For higher precision
applications, please refer to 16-bit DACs AD5541, AD5542,
and AD5544.
The AD5551 and AD5552 are available in an SO package.
