DAC6573IPW屬于集成電路（IC）的數模轉換器（DAC）。由美國德州儀器公司制造生產的DAC6573IPW數模轉換器（DAC）數模轉換器（DAC、D/A、D2A 或 D 轉 A）可將數字信號轉換為緩沖或無緩沖的模擬電壓或電流。DAC 架構是否適合特定應用，要取決于分辨率和采樣頻率。DAC 通常用于音樂播放器，將數字數據流轉換為模擬音頻流。它們還用于電視和手機，將數字視頻數據轉換為模擬視頻信號，再連接到屏幕驅動器，以顯示單色或彩色圖像。

DESCRIPTION

The DAC6573 is a low-power, quad channel, 10-Bit

buffered voltage output DAC. Its on-chip precision

output amplifier allows rail-to-rail output swing. The

DAC6573 utilizes an I2C compatible two wire serial

interface supporting high-speed interface mode with

address support of up to sixteen DAC6573s for a total

of 64 channels on the bus.

The DAC6573 requires an external reference voltage

to set the output range of the DAC. The DAC6573

incorporates a power-on-reset circuit that ensures

that the DAC output powers up at zero volts and

remains there until a valid write takes place in the

device. The DAC6573 contains a power-down fea-

ture, accessed via the internal control register, that

reduces the current consumption of the device to 200

nA at 5 V.

The low power consumption of this part in normal

operation makes it ideally suited to portable battery

operated equipment. The power consumption is less

than 3 mW at VDD=5 V reducing to 1 μW in

power-down mode.

The DAC6573 is available in a 16-lead TSSOP

package.
