DAC8806/20EVM
This user’s guide describes the characteristics, operation, and use of the DAC8806/20
evaluation module (EVM). This EVM features either the DAC8806 (14-bit) or DAC8820
(16-bit) — a current output, multiplying digital-to-analog converter (DAC) with parallel
digital inputs in a convenient modular EVM form factor. A complete circuit description, a
schematic diagram, and bill of materials are included.

The DAC8806 and DAC8820 devices are 14-bit and 16-bit, multiplying DACs with a microprocessor and
TMS320 DSP-compatible parallel interface. The data bits are double-buffered so that the output can be
updated asynchronously using the LDAC pin. During normal operation, the DAC8806 and DAC8820
devices dissipate a mere 25

Developed for a wide range of supply voltages, these DACs can be operated from 2.7 V to 5.5 V. The
full-scale current output for these devices is 1.66 mA with a 10-V reference applied and has a typical
settling time of 0.5
