DAC8831 DAC IC Chip

DAC8831(16-Bit, Ultra-Low Power, Voltage-Output,Digital-to-Analog Converters)

Introduction

The DAC8830 and DAC8831 are single,16-bit,serial-input,voltage-output digital-to-analog converters (DACs) operating from a single 3V to 5V power supply.These converters provide excellent linearity (1 LSB INL), low glitch, low noise, and fast settling (1.0 μS to 1/2 LSB of full-scale output) over the specified temperature range of -40°C to +85°C.The output is unbuffered, which reduces the power consumption and the error introduced by the buffer.

These parts feature a standard high-speed (clock up to 50MHz)， 3V or 5V SPI serial interface to communicate with a DSP or microprocessor.

The DAC8830 output is 0V to V_REF.However, the other one provides bipolar output (±V_REF) when working with an external buffer. The DAC8831 and DAC8830 are both reset to zero code after power up.For optimum performance,a set of Kelvin connections to external reference and analog ground input are provided on the DAC8831.

The DAC8830 is available in an SO-8 package, and the DAC8831 in an SO-14 package. Both have industry standard pinouts.The DAC8831 is also available in a QFN-14 package.
