DESCRIPTION
The DAC7611 is a 12-bit digital-to-analog converter
(DAC) with guaranteed 12-bit monotonicity perfor-
mance over the industrial temperature range. It re-
quires a single +5V supply and contains an input shift
register, latch, 2.435V reference, DAC, and high speed
rail-to-rail output amplifier. For a full-scale step, the
output will settle to 1 LSB within 7µs. The device
consumes 2.5mW (0.5mA at 5V).
The synchronous serial interface is compatible with a
wide variety of DSPs and microcontrollers. Clock
(CLK), serial data in (SDI), and load strobe (LD)
comprise the serial interface. In addition, two control
pins provide a chip select (CS) function and an asyn-
chronous clear (CLR) input. The CLR input can be
used to ensure that the DAC7611 output is 0V on
power-up or as required by the application.
The DAC7611 is available in an 8-lead SOIC or 8-pin
plastic DIP package and is fully specified over the
industrial temperature range of –40°C to +85°C.
