DESCRIPTION
The DAC5578 (8 bit), DAC6578 (10 bit), and
DAC7578 (12 bit) are low-power, voltage-output, octal
channel, digital-to-analog converters (DACs). The
devices are monolithic, provide good linearity,and
minimize undesired code-to-code transient voltages
(glitch).
The devices use a versatile, 2-wire serial interface
that is I2C-compatible and operates at clock rates of
up to 3.4MHz. Multiple devices can share the same
bus.
The devices incorporate a power-on-reset (POR) circuit that ensures the DAC output powers up to
zero-scale or midscale until a valid code is written to
the device. These devices also contain a power-down
feature, accessed through the serial interface, that
reduces the current consumption of the devices to
typically 0.42μA at 5V. Power consumption is typically
2.32mW at 3V, reducing to 0.68μW in power-down
mode. The low power consumption and small
footprint make these devices ideal for portable,
battery-operated equipment.
The DAC5578, DAC6578, and DAC7578 are drop-in and functionally-compatible with the DAC7678. All
devices are available in a 4x4, QFN-24 package and
a TSSOP-16 package.
