Product Overview
The Texas Instruments DAC80501 is a voltage-output precision DAC in the Signal_Chain category. It supports 16-bit resolution with integral nonlinearity and differential nonlinearity specified from -1 to 1 LSB over the -40°C to +125°C operating temperature range. The positive supply operating range is 2.7 V to 5.5 V, with digital input thresholds of 1.62 V minimum for high level and 0.45 V maximum for low level.
The device integrates a 2.5 V precision internal reference with 5 ppm/°C maximum temperature drift. Using the internal reference, the buffered output full-scale ranges are 1.25 V, 2.5 V, or 5 V. Reference input voltage limits depend on VDD and the REF-DIV bit setting, allowing operation with either the reference divider disabled or enabled.
Package options include 8-pin WSON (DQF) and 10-pin VSSOP (DGS). The DGS VSSOP package has 170.1°C/W junction-to-ambient thermal resistance, while the DQF WSON package has 122.6°C/W. Serial control is provided through a 3-wire SPI-compatible interface up to 50 MHz or I2C operation at Standard, Fast, and Fast Mode Plus data rates.
