These devices include a 2.5-V, 4-ppm/°C internal reference, giving a full-scale output – DAC856x (16-Bit): 4 LSB INL voltage range of 2.5 V or 5 V. The internal reference • Glitch Impulse: 0.1 nV-s has an initial accuracy of ±5 mV and can source or • Bidirectional Reference: Input or 2.5-V Output sink up to 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 and 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 and remains at zero scale Internal Reference Current) until a valid code is written to the device, whereas the • Wide Power-Supply Range: 2.7 V to 5.5 V DACxx63 devices similarly power up at mid-scale. These devices contain a power-down feature that • 50-MHz SPI With Schmitt-Triggered Inputs reduces current consumption to typically 550 nA at • LDAC and CLR Functions 5 V. The low power consumption, internal reference, • Output Buffer With Rail-to-Rail Operation and small footprint make these devices ideal for • Packages: WSON-10 (3 mm × 3 mm), VSSOP-10 portable, battery-operated equipment. • Temperature Range: –40°C to 125°C The DACxx62 devices are drop-in and function- compatible with each other, as are the DACxx63 2 Applications devices. The entire family is available in MSOP-10 and SON-10 packages. • Portable Instrumentation • PLC Analog Output Module Device Information(1) • Closed-Loop Servo Control PART NUMBER PACKAGE BODY SIZE (NOM) • Voltage Controlled Oscillator Tuning DAC8562 VSSOP (10), • Data Acquisition Systems DAC8162 3.00 mm × 3.00 mm WSON (10) • Programmable Gain and Offset Adjustment DAC7562 (1) For all available packages, see the orderable addendum at the end of the data sheet.
