DAC8234 说明
The DAC8234 is a high-accuracy, quad-channel, 14-bit digital-to-analog converter (DAC) that operates from supply voltages of ±5V to ±18V in bipolar output mode, and from ±5V to +24V/-12V in unipolar mode. With a 5V reference, the DAC8234 can be configured to output ±10V, ±5V, 0V to 20V, or 0V to 10V. The DAC8234 provides 14-bit monotonicity, excellent integral nonlinearity (INL) error of ±0.5 LSB, low glitch, and low noise over the operating temperature range of -40°C to +105°C. This device is trimmed in production for very low zero and gain errors. In addition, the DAC8234 implements a user-programmable system-level calibration function to achieve ±0.031 LSB zero error and ±0.
