AD5339ARMZ

2.5 V to 5.5 V, 250 μA, 2-Wire Interface,  Dual Voltage Output, 8-/10-/12-Bit DACs

数模转换器- DAC Dual 12Bit 2Wire ITF 25v -55V IC

GENERAL DESCRIPTION AD5339ARMZ

The AD5337/AD5338/AD5339 are dual 8-, 10-, and 12-bit

buffered voltage output DACs, respectively. Each part is housed

in an 8-lead MSOP package and operates from a single 2.5 V to

5.5 V supply, consuming 250 μA at 3 V. On-chip output amplifiers

allow rail-to-rail output swing with a slew rate of 0.7 V/μs. A 2-

wire serial interface operates at clock rates up to 400 kHz. This

interface is SMBus compatible at VDD < 3.6 V. Multiple devices

can be placed on the same bus.

APPLICATIONS AD5339ARMZ

Portable battery-powered instruments

Digital gain and offset adjustment

Programmable voltage and current sources

Programmable attenuators

Industrial process control
