SBAS410A – FEBRUARY 2008 – REVISED FEBRUARY 2008 14-Bit, Quad Channel, Ultra-Low Glitch, Voltage Output DIGITAL-TO-ANALOG CONVERTER with 2.5V, 2ppm/ °C Internal Reference 234 • Relative Accuracy: 1LSB The DAC8164 is a low-power, voltage-output, four-channel, 14-bit digital-to-analog converter (DAC). • Glitch Energy: 0.15nV-s The device includes a 2.5V, 2ppm/ °C internal • Internal Reference: reference (enabled by default), giving a full-scale – 2.5V Reference Voltage (enabled by default) output voltage range of 2.5V. The internal reference – 0.004% Initial Accuracy (typ) has an initial accuracy of 0.004% 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 DAC8164 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. • 14-Bit Monotonic Over Temperature Range The DAC8164 incorporates a power-on-reset circuit • Settling Time: 10µs to ±0.006% 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: Up to 50MHz current consumption of the device to 1.3 µA at 5V. • On-Chip Output Buffer Amplifier with Power consumption is 2.6mW at 3V, reducing to Rail-to-Rail Operation 1.4 µW in power-down mode. The low power consumption, internal reference, and small footprint • 1.8V to 5.5V Logic Compatibility make this device ideal for portable, battery-operated • Temperature Range: –40°C to +105°C equipment. The DAC8164 is drop-in and functionally compatible with the DAC7564 and DAC8564, and functionally • Portable Instrumentation compatible with the DAC7565, DAC8165 and • Closed-Loop Servo-Control DAC8565. All these devices are available in a • Process Control, PLCs TSSOP-16 package. • Data Acquisition Systems • Programmable Attenuation • PC Peripherals RELATED DEVICES 16-BIT 14-BIT 12-BIT Pin and Functionally DAC8564 DAC8164 DAC7564 Compatible Functionally DAC8565 DAC8165 DAC7565 Compatible 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.
