Modular design for use with a variety of DSP and microcontroller interface boards
The DAC8803/14 is a quad, 16-bit, serial input, current output DAC operating from a single 5-V power
supply. This converter provides excellent linearity (
±
1 LSB INL), low glitch, low noise, and fast settling (0.3
µ
s typ. to
±
0.1% of full-scale output) over the specified temperature range of –40
°
C to 85
°
C. Four external
buffer and DPDT switches are provided on the EVM to allow unipolar and bipolar output operation.
The modular EVM form factor allows for direct evaluation of the DAC performance and operating
characteristics. This EVM is compatible with the 5-6K Interface (
SLAU104 ) and HPA-MCU Interface
( SLAU106 ) Boards from Texas Instruments and additional 3rd party boards such as the HPA449
demonstration board from SoftBaugh, Inc. ( www.softbaugh.com ) and the Speedy33™ from Hyperception,
Inc. ( www.hyperception.com ).
