SBAS496A –MARCH 2010–REVISED AUGUST 2010

8-/10-/12-Bit, Octal-Channel, Ultra-Low Glitch, Voltage Output, Two-Wire Interface

Digital-to-Analog Converters

Check for Samples: DAC5578, DAC6578, DAC7578

FEATURES

DESCRIPTION

•

Relative Accuracy:

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).

–

DAC5578 (8 bit): 0.25LSB INL

DAC6578 (10 bit): 0.5LSB INL

DAC7578 (12 bit): 1LSB INL

•

Glitch Energy: 0.15nV-s

Power-On Reset to Zero Scale or Midscale

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.

–

Devices in the TSSOP Package Reset to

Zero Scale

–

Devices in the QFN Package Reset to Zero

Scale or Midscale

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 0.42mA at 5V. Power consumption is typically

2.32mW at 3V, reducing to 0.68mW in power-down

mode. The low power consumption and small

footprint make these devices ideal for portable,

battery-operated equipment.

•

Ultra-Low Power Operation: 0.13mA/ch at 5V

Wide Power-Supply Range: +2.7V to +5.5V

2-Wire Serial Interface ( I²C™ compatible)

Temperature Range: –40°C to +125°C

APPLICATIONS

•

Portable Instrumentation

Closed-Loop Servo Control

Process Control

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.
