AD5346/AD5347/AD5348 Data Sheet
FEATURES GENERAL DESCRIPTION AD5346: octal 8-bit DAC
AD5347: octal 10-bit DAC
AD5348: octal 12-bit DAC
Low power operation: 1.4 mA (max) at 3.6 V
Power-down to 120 nA at 3 V, 400 nA at 5 V

Rail-to-rail output range: 0 V to VREF or 0 V to 2 Г— VREF
Power-on reset to 0 V
Simultaneous update of DAC outputs via LDAC pin
Asynchronous CLR facility
Readback
Buffered/unbuffered reference inputs
20 ns WR time
38-lead TSSOP/6 mm Г— 6 mm 40-lead LFCSP packaging
Temperature range: –40°C to +105°C The AD5346/AD5347/AD53481 are octal 8-, 10-, and 12-bit
DACs, operating from a 2.5 V to 5.5 V supply. These devices
incorporate an on-chip output buffer that can drive the output
to both supply rails, and also allow a choice of buffered or
unbuffered reference input. APPLICATIONS An asynchronous CLR input is also provided, which resets the
contents of the input register and the DAC register to all zeros. …
