DAC8564 DAC IC Chip

DAC8564(16-Bit, Quad Channel, Ultra-I 0w Glitch, Voltage Output,DIGITAL-TO-ANAL0G CONVERTER with 2.5V,2ppm/°C)

Introduction

The DAC8564 is a low-power,voltage-output,four-channel, 16-bit digital-to-analog converter (DAC). The device includes a 2.5V, 2ppm/ °C internal reference (enabled by default), giving a full-scale output voltage range of 2.5V. The internal reference has an initial accuracy of 0.004% and can source up to 20mA at the VREFH/VREFOUT pin. The device is monotonic,providesvery good linearity,and minimizes undesired code-to-code transient voltages(glitch). The DAC8564 uses a versatile 3-wire serial interface that operates at clock rates up to 50MHz.The interface is compatible with standard SPI™,QSPI nM, MicrowireTM, and digital signal processor (DSP) interfaces.

The DAC8564 incorporates a power-on-reset circuit that ensures the DAC output powers up at zero-scale and remains there until a valid code is written to the device. The device contains a power-down feature,accessed over the serial interface, that reduces the current consumption of the device to 1.3 μA at 5V.Power consumption is 2.9mW at 3V, reducing to 1.5 μW in power-down mode.The low-power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment.

The DAC8564 is drop-in and functionally compatible with the DAC8534 and DAC8554, and pin-compatible with DAC8555 and DAC8565. The DAC8564 is available in a TSSOP-16 package.
