MAX544集成电路（IC）的音频专用规格书PDF中文资料

General Description

The MAX544/MAX545 are serial-input, voltage-output, 14-bit digital-to-analog converters (DACs) that operate from a single +5V supply. They provide 14-bit performance (±0.5LSB INL and ±0.9LSB DNL) over temperature without any adjustments. The DAC output is unbuffered, resulting in a low supply current of 0.3mA and a low offset error of 0.6mV.

Features

♦ Full 14-Bit Performance Without Adjustments

♦ +5V Single-Supply Operation

♦ Low Power: 1.5mW

♦ 1µs Settling Time

♦ Unbuffered Voltage Output Directly Drives 60kΩ Loads ♦ SPI/QSPI/MICROWIRE-Compatible Serial Interface

♦ Power-On Reset Circuit Clears DAC Output to 0V (unipolar mode)

♦ Schmitt-Trigger Inputs for Direct Optocoupler Interface

♦ Pin-Compatible 16-Bit Upgrades (MAX541/MAX542)
