The LTC
voltage output, 12-bit digital-to-analog converter (DAC) in
an SO-8 package. It includes a rail-to-rail output buffer
amplifier and an easy-to-use 3-wire cascadable serial
interface. The LTC1456 includes a CLR pin that asynchro-
nously clears the DAC to zero scale.
The LTC1456 has an internal 2.048V reference and a full-
scale output of 4.095V. It operates on a 4.5V to 5.5V
supply, dissipating 2.2mW.
The low power supply current and the space saving SO-8
package make the LTC1456 ideal for battery-powered
applications.
