The internal reference has an initial • Glitch Energy: 0.1 nV-s accuracy of ±5 mV and can source or sink up to • Bidirectional Reference: Input or 2.5-V Output 20 mA at the VREFIN/VREFOUT pin. – Output Disabled by Default These devices are monotonic, providing excellent – ±5-mV Initial Accuracy (Max) linearity and minimizing undesired code-to-code transient voltages (glitch). They use a versatile three- – 4-ppm/°C Temperature Drift (Typ) wire serial interface that operates at clock rates up to – 10-ppm/°C Temperature Drift (Max) 50 MHz. The interface is compatible with standard – 20-mA Sink/Source Capability SPI™, QSPI™, Microwire™, and digital signal processor (DSP) interfaces. The DACxx62 devices • Power-On Reset to Zero Scale or Mid-Scale incorporate a power-on-reset circuit that ensures the • Low-Power: 4 mW (Typ, 5-V AVDD, Including DAC output powers up at zero scale until a valid code Internal Reference Current) is written to the device, whereas the DACxx63s • Wide Power-Supply Range: 2.7 V to 5.5 V similarly power up at mid-scale. These devices contain a power-down feature that reduces current • 50-MHz SPI With Schmitt-Triggered Inputs consumption to typically 550 nA at 5 V. The low • LDAC and CLR Functions power consumption, internal reference, and small • Output Buffer With Rail-to-Rail Operation footprint make these devices ideal for portable, battery-operated equipment. • Packages: SON-10 (3x3 mm), MSOP-10 • Temperature Range: –40°C to 125°C The DACxx62 devices are drop-in and function- compatible with each other, as are the DACxx63s. APPLICATIONS The entire family is available in MSOP-10 and SON- 10 packages. • Portable Instrumentation • Bipolar Outputs (reference design) Table 1. RELATED DEVICES • PLC Analog Output Module (reference design) 16-BIT 14-BIT 12-BIT • Closed-Loop Servo Control Reset to zero DAC8562 DAC8162 DAC7562 • Voltage Controlled Oscillator Tuning Reset to mid-scale DAC8563 DAC8163 DAC7563 • Data Acquisition Systems • Programmable Gain and Offset Adjustment 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.
