1 / 26 page DAC8832 ® BurrBrown Products from Texas Instruments FEATURES DESCRIPTION APPLICATIONS RFB INV AGNDF AGNDS DGND DAC DAC Latch Input Register DAC8832 + − +V −V OPA277 OPA704 OPA727 SDI SCLK LDAC V OUT V O V DD R FB R INV V REF−F V REF− S Serial Interface and Control Logic CS DAC8832 SBAS380A – FEBRUARY 2006 – REVISED APRIL 2006 16-Bit, Ultra-Low Power, Voltage-Output Digital-to-Analog Converter • 16-Bit Resolution The DAC8832 is a single, 16-bit, serial-input, voltage-output digital-to-analog converter (DAC) • 2.7 V to 5.5 V Single-Supply Operation operating from a single 3 V to 5 V power supply. The • Very Low Power: 15 µW for 3 V Power DAC8832 provides excellent linearity (1 LSB INL), • High Accuracy, INL: 1 LSB low glitch, low noise, and fast settling (1.0 µS to 1/2 • Low Glitch: 10 nV-s LSB of full-scale output) over the specified temperature range of –40 °C to +85°C. The output is • Low Noise: 18n V/√Hz unbuffered, which reduces the power consumption • Fast Settling: 1.0 µS and the error introduced by the buffer. • Fast SPI™ Interface, up to 50 MHz This device features a standard high-speed (clock up • Reset to Mid-Code to 50MHz), 3 V or 5 V SPI serial interface to • Schmitt-Trigger Inputs for Direct Optocoupler communicate with the DSP or microprocessors. Interface The DAC8832 provides unipolar or bipolar output ( ±V REF) when working with an external buffer, and is reset to mid-code after power-up. For optimum • Portable Equipment performance, a set of Kelvin connections to the external reference and the analog ground input are • Automatic Test Equipment provided. • Industrial Process Control The DAC8832 is available in a QFN-14 package, • Data Acquisition Systems and is pin-to-pin compatible with the DAC8831IRGY, • Optical Networking which is reset to zero-code after power-up.
