GENERAL DESCRIPTION
The AD5306/AD5316/AD5326¹ are quad 8-/10-/12-bit buffered voltage output DACs in 16-lead TSSOP packages that operate from a single 2.5 V to 5.5 V supply, consuming 500 μA at 3 V. Their on-chip output amplifiers allow rail-to-rail output swing with a slew rate of 0.7 V/μs. A 2-wire serial interface, which operates at clock rates up to 400 kHz, is used. This interface is SMBus-compatible at VDD< 3.6 V. Multiple devices can be placed on the same bus.
