AD5306BRU-REEL

2.5 V至5.5 V ， 400 μA ， 2线接口，四路电压输出， 8位/ 10位/ 12位DAC 2.5 V to 5.5 V, 400 μA, 2-Wire Interface, Quad Voltage Output, 8-/10-/12-Bit DACs

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.
