TI DAC8734高精度四路16位数模转换方案
TI 公司的DAC8734是高精度四路16位数模转换器(DAC),工作电压从±5V 到±18V,或单极电压从±5V 到+24V/-12V. DAC8734的噪音为60nV/Hz,建立时间为6us,可配置增益为X2/X4,模拟输出监视和降功耗模式,主要用在自动测试设备,仪表,工业过程控制和通信.本文介绍了DAC8734的主要特性,方框图和典型应用电路.
The DAC8734 is a high-accuracy, quad-channel, 16-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 DAC8734 can be configured to output ±10V, ±5V, 0V to 20V, or 0V to 10V. The DAC8734 provides 16-bit monotonicity, excellent integral nonlinearity (INL) error of ±1 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 DAC8734 implements a user-programmable system-level calibration function to achieve ±0.125 LSB zero error and ±1 LSB gain error.
