These devices include a 2.5-V, 4-ppm/°C internal reference, giving a full-scale output – 4-ppm/°C Temperature Drift (Typ) voltage range of 2.5 V or 5 V. The internal reference • Power-On Reset to Zero Scale or Mid-Scale has an initial accuracy of ±5 mV and can source or • Low-Power: 4 mW at 5-V AVDD sink up to 20 mA at the VREFIN/VREFOUT pin. • Wide Power-Supply Range: 2.7 V to 5.5 V These devices are monotonic, providing excellent • 50-MHz SPI With Schmitt-Triggered Inputs linearity and minimizing undesired code-to-code transient voltages (glitch). They use a versatile three- • LDAC and CLR Functions wire serial interface that operates at clock rates up to • Output Buffer With Rail-to-Rail Operation 50 MHz. The interface is compatible with standard • Pin-to-Pin Compatible With DAC8562 Family SPI™, QSPI™, Microwire, and digital signal • 5-V TTL I/O Enabled processor (DSP) interfaces. The DACxx62T devices incorporate a power-on-reset circuit that ensures the • Packages: WSON-10 (3 mm × 3 mm), VSSOP-10 DAC output powers up and remains at zero scale • Temperature Range: –40°C to 125°C until a valid code is written to the device, whereas the DACxx63T devices similarly power up at mid-scale. 2 Applications These devices contain a power-down feature that reduces current consumption to typically 550 nA at • Portable Instrumentation 5 V. The low power consumption, internal reference, • PLC Analog Output Module and small footprint make these devices ideal for • Bipolar Outputs (Section 9.2.2) portable, battery-operated equipment. • Closed-Loop Servo Control The DACxx62T devices are drop-in and function- • Voltage Controlled Oscillator Tuning compatible with each other, as are the DACxx63T devices. The entire family is available in VSSOP-10 • Data Acquisition Systems and WSON-10 packages. • Programmable Gain and Offset Adjustment Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) DAC8562T VSSOP (10), DAC8162T 3.00 mm × 3.00 mm WSON (10) DAC7562T (1) For all available packages, see the orderable addendum at the end of the data sheet.
