DAC7643 Datasheet Digital-to-analog Converter

Manufacturer: Burr-Brown (Texas Instruments)

Overview: DAC7642 DAC7642 DAC7643 DAC7643 SBAS233 – DECEMBER 2001 16-Bit, Dual Voltage Output DIGITAL-TO-ANALOG.

This datasheet includes multiple variants, all published together in a single manufacturer document.

General Description

The DAC7642 and DAC7643 are dual channel, 16-bit, voltage output Digital-to-Analog Converters (DACs) which provide 15-bit monotonic performance over the specified temperature range.

They accept 16-bit parallel input data, have double-buffered DAC input logic (allowing simultaneous update of all DACs), and provide a readback mode of the internal input registers.

Programmable asynchronous reset clears all registers to a mid-scale code of 8000H (DAC7642) or to a zero-scale code of 0000H (DAC7643).
