• Manufacturer Part Number: LTC1650
• Description: Low Glitch 16-Bit Voltage Output DAC
• Manufacturer: Linear Technology

TYPICAL PERFOR A CE CHARACTERISTICS
LTC1650
PIN
V
The output will swing from REFLO to REFHI in unipolar
mode and from (2 • REFLO – REFHI) to REFHI in bipolar
mode.
V
gets reset when CLR is active, when any of the supplies
drop below 2.5V or when the part powers-up. The output
will stay at this voltage until a new code is loaded into the
DAC register.
