DAC8832
SBAS380B FEBRUARY 2006 REVISED SEPTEMBER 2007

16-Bit, Ultra-Low Power, Voltage-Output Digital-to-Analog Converter
1

FEATURES
16-Bit Resolution 2.7 V to 5.5 V Single-Supply Operation Very Low Power: 15 W for 3 V Power High Accuracy, INL: 1 LSB Low Noise: 18n V/Hz Fast Settling: 1.0 S Fast SPITM Interface, up to 50 MHz Reset to Mid-Code Schmitt-Trigger Inputs for Direct Optocoupler Interface

DESCRIPTION
The DAC8832 is a single, 16-bit, serial-input, voltage-output digital-to-analog converter (DAC) operating from a single 3 V to 5 V power supply. The DAC8832 provides excellent linearity (1 LSB INL), low glitch, low noise, and fast settling (1.0 S 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. This device features a standard high-speed (clock up to 50MHz), 3 V or 5 V SPI serial interface to communicate with a DSP or microprocessor. The DAC8832 provides unipolar or bipolar output ( VREF) when working with an external buffer, and is reset to mid-code after power-up. For optimum performance, a set of Kelvin connections to the external reference and the analog ground input are provided. The DAC8832 is available in a QFN-14 package, and is pin-to-pin compatible with the DAC8831IRGY, which is reset to zero code after power-up.
