DA C7 728 DAC7728 DA C7 728 www.ti.com SBAS461A – JUNE 2009 – REVISED NOVEMBER 2009 Octal, 12-Bit, Low-Power, High-Voltage Output, Parallel Input
DIGITAL-TO-ANALOG CONVERTER
Check for Samples: DAC7728 FEATURES DESCRIPTION The DAC7728 is a low-power, octal, 12-bit
digital-to-analog converter (DAC). With a 5V
reference, the output can either be a bipolar В±15V
voltage when operating from a dual В±15.5V (or
higher) power supply, or a unipolar 0V to +30V
voltage when operating from a +30.5V power supply.
With a 5.5V reference, the output can either be
В±16.5V for a dual В±17V (or higher) power supply, or a
unipolar 0V to +33V voltage when operating from a
+33.5V (or higher) power supply. This DAC provides
low-power operation, good linearity, and low glitch
over the specified temperature range of –40°C to
+105В°C. This device is trimmed in manufacturing and
has very low zero and full-scale error. In addition,
user calibration can be performed over the entire
signal chain. The output range can be offset by using
the DAC Offset Register. 1 2 Bipolar Output: В±3V, up to В±16.5V
Unipolar Output: 0V to +33V
