GENERAL DESCRIPTION
The AD5421 is a complete, loop-powered, 4 mA to 20 mA
digital-to-analog converter (DAC) designed to meet the needs
of smart transmitter manufacturers in the industrial control
industry. The DAC provides a high precision, fully integrated,
low cost solution in compact TSSOP and LFCSP packages.
The AD5421 includes a regulated voltage output that is used to
power itself and other devices in the transmitter. This regulator
provides a regulated 1.8 V to 12 V output voltage. The AD5421
also contains 1.22 V and 2.5 V references, thus eliminating the
need for a discrete regulator and voltage reference.
The AD5421 can be used with standard HART® FSK protocol
communication circuitry without any degradation in specified
performance. The high speed serial interface is capable of opera-
ting at 30 MHz and allows for simple connection to commonly
used microprocessors and microcontrollers via a SPI-compatible,
3-wire interface.
The AD5421 is guaranteed monotonic to 16 bits. It provides
0.0015% integral nonlinearity, 0.0012% offset error, and
0.0006% gain error under typical conditions.
The AD5421 is available in a 28-lead TSSOP and a 32-lead
LFCSP specified over the extended industrial temperature range
of −40°C to +105°C.
