With a 5V • Unipolar Output: 0V to +33V reference, the output can either be a bipolar ±15V • 12-Bit Resolution voltage when operating from dual ±15.5V (or higher) • Low Power: 14.4mW/Ch (Bipolar Supply) power supplies, or a unipolar 0V to +30V voltage • Relative Accuracy: 1 LSB Max when operating from a +30.5V (or higher) power supply. With a 5.5V reference, the output can either • Low Zero/Full-Scale Error: ±1 LSB Max be a bipolar ±16.5V voltage when operating from dual • Flexible System Calibration ±17V (or higher) power supplies, or a unipolar 0V to • Low Glitch: 4nV-s +33V voltage when operating from a +33.5V (or higher) power supply. This DAC provides low-power • Settling Time: 15ms operation, good linearity, and low glitch over the • Channel Monitor Output specified temperature range of –40°C to +105°C. This • Programmable Gain: x4/x6 device is trimmed in manufacturing and has very low zero-code and gain error. In addition, system level • Programmable Offset calibration can be performed over the entire signal • SPI™: Up to 50MHz, 1.8V/3V/5V Logic chain. The output range can be offset by using the • Schmitt Trigger Inputs DAC offset register. • Daisy-Chain with Sleep Mode Enhancement The DAC7718 features a standard, high-speed serial • Packages: QFN-48 (7x7mm), TQFP-64 peripheral interface (SPI) that operates at up to (10x10mm) 50MHz and is 1.8V, 3V, and 5V logic compatible, to communicate with a DSP or microprocessor. The input data of the device are double-buffered. An APPLICATIONS asynchronous load input (LDAC) transfers data from • Automatic Test Equipment the DAC data register to the DAC latch. The • PLC and Industrial Process Control asynchronous CLR input sets the output of all eight • Communications DACs to AGND. The VMON pin is a monitor output that connects to the individual analog outputs, the offset DAC, the reference buffer outputs, and two external inputs through a multiplexer (mux). The DAC7718 is pin-to-pin and function-compatible with the DAC8718 (16-bit) and the DAC8218 (14-bit). 1 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet. 2 DSP is a trademark of Texas Instruments. 3 SPI, QSPI are trademarks of Motorola Inc. 4 Microwire is a trademark of National Semiconductor. 5 All other trademarks are the property of their respective owners.
