The internal reference – 0.02% Initial Accuracy has an initial accuracy of 0.02% and can source up to 20mA at the VREFH/VREFOUT pin. The device is – 2ppm/ °C Temperature Drift (typ) monotonic, provides very good linearity, and – 5ppm/ °C Temperature Drift (max) minimizes undesired code-to-code transient voltages – 20mA Sink/Source Capability (glitch). The DAC8564 uses a versatile 3-wire serial interface that operates at clock rates up to 50MHz. • Power-On Reset to Zero-Scale The interface is compatible with standard SPI™, • Ultra-Low Power Operation: 1mA at 5V QSPI™, Microwire™, and digital signal processor • Wide Power Supply Range: +2.7V to +5.5V (DSP) interfaces. • 16-Bit Monotonic Over Temperature Range The DAC8564 incorporates a power-on-reset circuit • Settling Time: 10µs to ±0.003% Full-Scale that ensures the DAC output powers up at zero-scale and remains there until a valid code is written to the Range (FSR) device. The device contains a power-down feature, • Low-Power Serial Interface with accessed over the serial interface, that reduces the Schmitt-Triggered Inputs current consumption of the device to 1.3 µA at 5V. • On-Chip Output Buffer Amplifier with The low-power consumption, internal reference, and Rail-to-Rail Operation small footprint make this device ideal for portable, battery-operated equipment. The power consumption • Drop-In and Functionally Compatible with is 2.9mW at 3V, reducing to 1.5 µW in power-down DAC8534 and DAC8554 mode. • Pin-Compatible with DAC8555 and DAC8565 The DAC8564 is drop-in and functionally compatible • 1.8V to 5.5V Logic Compatibility with the DAC8534 and DAC8554, and pin-compatible • Temperature Range: –40°C to +105°C with DAC8555 and DAC8565. The DAC8564 is available in a TSSOP-16 package. • Portable Instrumentation • Closed-Loop Servo-Control • Process Control • Data Acquisition Systems • Programmable Attenuation • PC Peripherals 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 SPI, QSPI are trademarks of Motorola, Inc. 3 Microwire is a trademark of National Semiconductor. 4 All other trademarks are the property of their respective owners.
