Overview
The DAC5573IPW is a low-power, quad-channel, 8-bit buffered voltage output Digital-to-Analog Converter (DAC) produced by Texas Instruments. It features an on-chip precision output amplifier that allows for rail-to-rail output swing. The device utilizes an I2C-compatible two-wire serial interface, supporting high-speed interface mode with address support for up to sixteen DAC5573s, enabling a total of 64 channels on the bus. This DAC is particularly suited for applications requiring low power consumption and high precision, making it ideal for portable battery-operated equipment and various industrial control systems.

Q & A
- What is the resolution of the DAC5573?
The DAC5573 has an 8-bit resolution. - How many channels does the DAC5573 support?
The DAC5573 supports four channels. - What is the operating temperature range of the DAC5573?
The operating temperature range is from -40°C to 105°C. - What type of interface does the DAC5573 use?
The DAC5573 uses an I2C-compatible two-wire serial interface. - What is the update rate of the DAC5573?
The update rate is 188 kSPS. - How does the power-on-reset feature work?
The power-on-reset circuit ensures that the DAC output powers up at zero volts and remains there until a valid write takes place. - What is the power consumption in normal operation and power-down mode?
In normal operation, the power consumption is less than 3 mW at VDD = 5 V, and in power-down mode, it reduces to 1 µW. - What is the package type of the DAC5573?
The DAC5573 is available in a 16-lead TSSOP package. - Can multiple DAC5573s be addressed on the same bus?
Yes, up to sixteen DAC5573s can be addressed on the same bus, supporting a total of 64 channels. - What is the current consumption in power-down mode?
The current consumption in power-down mode is 200 nA at 5 V.
