Details
The DAC80504RTER is a low-power, four-channel, buffered voltage output digital-to-analog converter (DAC) with 16-bit resolution. The DAC80504RTER features a low-drift 2.5V internal reference voltage, eliminating the need for an external accuracy reference in most applications. The user-selectable gain configuration provides full-scale output voltages of 1.25V (gain = ½), 2.5V (gain = 1), or 5V (gain = 2). These devices are powered by a single power supply ranging from 2.7V to 5.5V, have specified monotonicity, and can provide a high linearity of ±1LSB INL.
Communicate with the DAC80504RTER through a 4-wire serial interface with an operating clock rate of 50MHz. The VIO pin enables the serial interface to operate within a voltage range of 1.7V to 5.5V. The flexible interface of DAC80504RTER enables it to be used in a wide range of industry-standard microprocessors and microcontrollers.
The DAC80504RTER adopts a power-on reset circuit. After power-on, it can keep the DAC output at zero level or intermediate level until a valid code is written into the device. This device consumes a low current of 0.7mA per channel at 5.5V, and thus is highly suitable for battery-powered devices. The power-off characteristic of each channel can reduce the current consumption of the device to 15µA.
The DAC80504RTER can operate normally within a temperature range of -40 °C to +125°C and is available in a 3mm × 3mm QFN compact package.
