DA DAC1220 C1 220 www.ti.com. SBAS082G – FEBRUARY 1998 – REVISED SEPTEMBER 2009 20-Bit, Low-Power
Digital-to-Analog Converter
Check for Samples: DAC1220 FEATURES DESCRIPTION The DAC1220 is a 20-bit digital-to-analog (D/A)
converter offering 20-bit monotonic performance over
the specified temperature range. It utilizes
delta-sigma technology to achieve inherently linear
performance in a small package at very low power.
The resolution of the device can be programmed to
20 bits for Full-Scale, settling to 0.003% within 15ms
typical, or 16 bits for Full-Scale, settling to 0.012%
within 2ms max. The output range is two times the
external reference voltage. On-chip calibration
circuitry dramatically reduces low offset and gain
errors. 1 2 20-Bit Monotonicity Ensured Over –40°C to
