Maxim MAX547BCQH-D

Voltage - Buffered并联±5V0°C ~ 70°C

Overview

The MAX547BCQH contains eight 13-bit, voltage-output digital-to-analog converters (DACs). On-chip precision output amplifiers provide the voltage outputs. The MAX547BCQH operates from a ±5V supply. Bipolar output voltages with up to ±4.5V voltage swing can be achieved with no external components. The MAX547BCQH has four separate reference inputs; each is connected to two DACs, providing different full-scale output voltages for every DAC pair. The MAX547BCQH features double-buffered interface logic with a 13-bit parallel data bus. Each DAC has an input latch and a DAC latch. Data in the DAC latch sets the output voltage. The eight input latches are addressed with three address lines. Data is loaded to the input latch with a single write instruction. An asynchronous load (active-low LD_) input transfers data from the input latch to the DAC latch. The four active-low LD_ inputs each control two DACs, and all DAC latches can be updated simultaneously by asserting all active-low LD_ pins. An asynchronous clear (active-low CLR) input resets the output of all eight DACs to AGND_. Asserting active-low CLR resets both the DAC and the input latch to bipolar zero (1000hex). On power-up, reset circuitry performs the same function as active-low CLR. All logic inputs are TTL/CMOS compatible. The MAX547BCQH is available in 44-pin plastic quad flat pack and 44-pin PLCC packages.
