Description

The HI5828 is a Dual 12-bit, 125+MSPS (Mega Samples Per Second), high speed, low power, D/A converter which is implemented in an advanced CMOS process. Operating from a single +3V to +5V supply, the converter provides 20mA of full scale output current and includes edge-triggered CMOS input data latches. Low glitch energy and excellent frequency domain performance is achieved by the HI5828's segmented current source architecture.

This HI5828 complements the CommLink HI5x60 and HI5x28 family of high speed converters, which includes 8, 10, 12, and 14-bit devices
