DAC7632

具有串行接口的 16 位双路电压输出 DAC

The is a 16-bit, dual channel, voltage output, Digital-to-Analog Converter DAC which provides 15-bit monotonic performance over the specified temperature range. The device accepts 24-bit serial input data, has double-buffered DAC input logic allowing simultaneous update of both DACs, and provides a serial data output for daisy-chaining multiple devices. A programmable asynchronous reset clears all registers to a mid-scale code of 8000H or to a zero-scale code of 0000H. The DAC7632 can operate from a single +5V supply or from +5V and –5V supplies, providing an output range of 0V to +2.5V or –2.5V to +2.5V, respectively.

Low power and small size per DAC make the DAC7632 ideal for industrial process control, data acquisition systems, and closed-loop servo-control. The DAC7632 is available in an LQFP-32 package and specified over a –40°C to +85°C temperature range.
