PRODUCTION DATA. DAC8551-Q1, DAC6551-Q1 SLASEB8C – FEBRUARY 2016 – REVISED NOVEMBER 2016 DACx551-Q1 Automotive 16-, 12-Bit, Ultralow-Glitch, Voltage-Output DAC 1 1 Features 1 • Qualified for Automotive Applications • AEC-Q100 Qualified With the Following Results: – Device Temperature Grade 1: –40°C to 125°C Ambient Operating Temperature Range – Device HBM ESD Classification Level 2 – Device CDM ESD Classification Level C4B • Relative Accuracy: – DAC8551-Q1 (16-Bit): 4 LSB INL – DAC6551-Q1 (12-Bit): 0.3 LSB INL • Ultralow Glitch Impulse: 0.1 nV-s • Settling Time: 8 μs to ±0.003% FSR • Power Supply: 3 V to 5.5 V • Power-On Reset to Zero Scale • MicroPower Operation: 160 μA at 5 V • Low-Power Serial Interface With Schmitt- Triggered Inputs • On-Chip Output Buffer Amplifier With Rail-to-Rail Operation • Power-Down Capability • Binary Input • SYNC Interrupt Facility • Available in a Tiny VSSOP-8 Package 2 Applications • Automotive Radar • Automotive Sensors 3 Description The DAC8551-Q1 and DAC6551-Q1 are small, low- power, voltage-output, 16- and 12-bit digital-to-analog converters (DACs) qualified for automotive applications. The DACx551-Q1 devices provide good linearity and minimize undesired code-to-code transient voltages. The devices use a versatile 3-wire serial interface that operates at clock rates to 30 MHz and is compatible with standard SPI, QSPI, Microwire, and digital signal-processor (DSP) interfaces. The DACx551-Q1 devices require an external reference voltage to set the output range. The devices incorporate a power-on-reset circuit that ensures the DAC output powers up at 0 V and remains there until a valid write to the device takes place. The devices contain a power-down feature, accessed over the serial interface, that reduces the current consumption to 800 nA at 5 V. The DACx551-Q1 devices power consumption is only 800 µW at 5 V, reducing to less than 4 μW in power- down mode. The DACx551-Q1 devices are available in a VSSOP-8 package.
