The internal reference – 2.5V Reference Voltage (enabled by default) has an initial accuracy of 0.004% and can source up – 0.004% Initial Accuracy (typ) to 20mA at the VREFH/VREFOUT pin. The device is – 2ppm/°C Temperature Drift (typ) monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages – 5ppm/°C Temperature Drift (max) (glitch). The DAC8565 use a versatile 3-wire serial – 20mA Sink/Source Capability interface that operates at clock rates up to 50MHz. It • Power-On Reset to Zero-Scale or Midscale is compatible with standard SPI ™, QSPI ™, Microwire ™, and digital signal processor (DSP) • Asynchronous Clear to Zero-Scale or Midscale interfaces. • Ultra-Low Power Operation: 1mA at 5V The DAC8565 incorporates a power-on-reset circuit • Wide Power Supply Range: +2.7V to +5.5V that ensures the DAC output powers up at either • 16-Bit Monotonic Over Temperature Range zero-scale or midscale until a valid code is written to • Settling Time: 10 μs to ±0.003% Full-Scale the device. The device contains a power-down Range (FSR) feature, accessed over the serial interface, that reduces the current consumption of the device to • Low-Power Serial Interface with 1.3 μA at 5V. The low power consumption, internal Schmitt-Triggered Inputs: Up to 50MHz reference, and small footprint make this device ideal • On-Chip Output Buffer Amplifier with for portable, battery-operated equipment. The power Rail-to-Rail Operation consumption is 2.9mW at 3V, reducing to 1.5 μW in • 1.8V to 5.5V Logic Compatibility power-down mode. • Temperature Range: –40°C to +105°C The DAC8565 is drop-in and functionally compatible with the DAC7564 and DAC8164, and functionally APPLICATIONS compatible with the DAC7565, DAC8165, and DAC8564. All these devices are available in a • Portable Instrumentation TSSOP-16 package. • Closed-Loop Servo-Control • Process Control, PLCs • Data Acquisition Systems • Programmable Attenuation • PC Peripherals RELATED DEVICES 16-BIT 14-BIT 12-BIT Pin and Functionally DAC8565 DAC8165 DAC7565 Compatible Functionally DAC8564 DAC8164 DAC7564 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.
