The DAC8734SPFB is a high-accuracy quad-channel 16-bit Digital-to-analog Converter (DAC) operates from supply voltages of ±5 to ±18V in bipolar output mode and from ±5 to +24V/-12V in unipolar mode. The DAC8734 provides 16-bit monotonicity, excellent integral nonlinearity (INL) error of ±1LSB, low glitch and low noise over the operating temperature range of -40 to 105°C. This device is trimmed in production for very low zero and gain errors. In addition, the DAC8734 implements user-programmable system-level calibration function to achieve ±0.125LSB zero error and ±1LSB gain error. The DAC8734 has integrated reference buffers and output buffers. It features a standard high-speed 1.8/3/5V serial peripheral interface that operates at clock rates of up to 50MHz to communicate with a DSP or microprocessor. The four DAC channels and the auxiliary registers are addressed with four address bits. The device features double-buffered interface logic for simultaneous updates of DAC.
