PRODUCT OVERVIEW

What Is the DAC8564IBPWR?

DAC8564IBPWR is a low-power, voltage-output, quad-channel, 16-bit digital-to-analog converter (DAC) from Texas Instruments. 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 V_REFH/V_REFOUT pin.[reference:0]

The DAC8564IBPWR is monotonic, provides very good linearity, and minimizes undesired code-to-code transient voltages (glitch). The device uses a versatile 3-wire serial interface that operates at clock rates up to 50MHz, compatible with standard SPI, QSPI, Microwire, and 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.[reference:1]

The device contains a power-down feature, accessed over the serial interface, that reduces the current consumption to 1.3µA at 5V. Power consumption is 2.9mW at 3V, reducing to 1.5µW in power-down mode. The low power consumption, internal reference, and small footprint make this device ideal for portable, battery-operated equipment. The DAC8564IBPWR is available in a 16-lead TSSOP package with a 4.40mm body width, rated for operation from –40°C to +105°C. The device is RoHS compliant (ROHS3), REACH unaffected, and in active production.[reference:2]

16-Bit Quad-Channel DAC Four 16-bit voltage-output DAC channels with 10µs settling time and 4LSB relative accuracy (INL).

2.5V Internal Reference 2.5V, 2ppm/°C internal reference (enabled by default) with 0.004% initial accuracy, sourcing up to 20mA.

Ultra-Low Power 1mA quiescent current at 5V, 1.3µA in power-down mode, ideal for portable and battery-powered applications.
