3 power-down functions The AD5301/AD5311/AD53211 are single 8-/10-/12-bit, buffered, voltage-output DACs that operate from a single 2.5 V to
5.5 V supply, consuming 120 ОјA at 3 V. The on-chip output
amplifier allows rail-to-rail output swing with a slew rate of
0.7 V/Ојs. It uses a 2-wire (I2C-compatible) serial interface that
operates at clock rates up to 400 kHz. Multiple devices can share
the same bus. APPLICATIONS The reference for the DAC is derived from the power supply
inputs and thus gives the widest dynamic output range. These …
