These devices Ambient Operating Temperature Range include a 2.5-V, 4-ppm/°C internal reference, giving a full-scale output voltage range of 2.5 V or 5 V. The – Device HBM ESD Classification Level 2 internal reference has an initial accuracy of ±5 mV – Device CDM ESD Classification Level C4B and can source or sink up to 20 mA at the • Relative Accuracy: VREFIN/VREFOUT pin. – DAC756x (12-Bit): 0.3 LSB INL These devices are monotonic, providing excellent – DAC816x (14-Bit): 1 LSB INL linearity and minimizing undesired code-to-code transient voltages (glitch). They use a versatile three- – DAC856x (16-Bit): 4 LSB INL wire serial interface that operates at clock rates up to • Glitch Impulse: 0.1 nV-s 50 MHz. The interface is compatible with standard • Bidirectional Reference: Input or 2.5-V Output SPI™, QSPI™, Microwire, and digital signal processor (DSP) interfaces. The DACxx62-Q1 – Output Disabled by Default devices incorporate a power-on-reset circuit that – ±5-mV Initial Accuracy (Max) ensures the DAC output powers up and remains at – 4-ppm/°C Temperature Drift (Typ) zero scale until a valid code is written to the device, whereas the DACxx63-Q1 devices similarly power up – 10-ppm/°C Temperature Drift (Max) at mid-scale. These devices contain a power-down – 20-mA Sink and Source Capability feature that reduces current consumption to typically • Power-On Reset to Zero Scale or Mid-Scale 550 nA at 5 V. The low power consumption, internal • Low-Power: 4 mW (Typ, 5-V AVDD, Including reference, and small footprint make these devices ideal for portable, battery-operated equipment. Internal Reference Current) • Wide Power-Supply Range: 2.7 V to 5.5 V The DACxx62-Q1 devices are drop-in and function- compatible with each device in this family, as are the • 50-MHz SPI With Schmitt-Triggered Inputs DACxx63-Q1 devices. The entire family is available in • LDAC and CLR Functions a 10-pin VSSOP-10 (DGS) package. • Output Buffer With Rail-to-Rail Operation • Package: VSSOP-10 Device Information(1) PART NUMBER PACKAGE BODY SIZE (NOM) 2 Applications DAC7562-Q1 DAC7563-Q1 • Portable Instrumentation DAC8162-Q1 • PLC Analog Output Module VSSOP (10) 3.00 mm × 3.00 mm DAC8163-Q1 • Closed-Loop Servo Control DAC8562-Q1 • Voltage Controlled Oscillator Tuning DAC8563-Q1 • Data Acquisition Systems (1) For all available packages, see the orderable addendum at • Programmable Gain and Offset Adjustment the end of the datasheet.
