Product Summary

The DAC1221E is a Digital-to-Analog (D/A) converter. It is offering 16-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 output range is two times the external reference voltage. On-chip calibration circuitry dramatically reduces offset and gain errors. The applications of the DAC1221E are (1)process control; (2)ate pin electronics; (3)closed-loop servo-control; (4)smart transmitters; (5)portable instruments; (6)vco control.

Parametrics

DAC1221E absolute maximum ratings: (1)AVDD to DVDD: ±0.3V; (2)AVDD to AGND: –0.3V to 4V; (3)DVDD to DGND: –0.3V to 4V; (4)AGND to DGND: ±0.3V; (5)VREF Voltage to AGND: 1.0V to 1.5V; (6)Digital Input Voltage to DGND: –0.3V to DVDD + 0.3V; (7)Digital Output Voltage to DGND: –0.3V to DVDD + 0.3V; (8)Package Power Dissipation: (TJMAX – TA)/θJA; (9)Maximum Junction Temperature (TJMAX): +150℃; (10)Thermal Resistance, θJA: 200℃/W; (11)Lead Temperature (soldering, 10s): +300℃.

Features

DAC1221E features: (1)16-bit monotonicity guaranteed over –40 to +85℃; (2)low power: 1.2mW; (3)voltage output; (4)settling time: 2ms to 0.012%; (5)max linearity error: 30ppm; (6)on-chip calibration.
