DAC8571中文资料低功耗轨到轨输出 16 位 I2C 输入 DAC数据手册TI规格书

描述 Description

The DAC8571 is a small low-power, 16-bit voltage output DAC with an I2C compatible two-wire serial interface. Its on-chip precision output amplifier allows rail-to-rail output swing and settles within 10 microseconds. The DAC8571 architecture is 16-bit monotonic, and factory trimming typically achieves ±4 mV absolute accuracy at all codes. The DAC8571 requires an external reference voltage to set its output voltage range.

The low power consumption and small size of this part make it ideally suited to portable battery operated equipment. The power consumption is typically 800 µW at VDD = 5 V reducing to 1 µWin power-down mode.

The DAC8571 incorporates a 2-wire I2C interface. Standard, fast, and high-speed modes of I2C operation are all supported up to 3.4 MHz serial clock speeds. Multichannel synchronous data update and power-down operations are supported through the I2C bus. DAC8571 is also capable of transmitting the contents of its serial shift register, a key feature for I2C system verification.

The DAC8571 is available in an 8-lead MSOP package and is specified over –40°C to 105°C.
