MAX547 - Octal / 13-Bit Voltage-Output DAC with Parallel Interface

General Description

The MAX547 contains eight 13-bit, voltage-output digital-toanalog converters (DACs).

On-chip precision output amplifiers provide the voltage outputs.

The MAX547 operates from a ±5V supply.

Key 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 (LD_ ) input transfers data from the.
  • input latch to the DAC latch. The four LD_ inputs each control two DACs, a.

19-0257; Rev 3; 12/95 Octal, 13-Bit Voltage-Output DAC with Parallel Interface _________________General Description The MAX547 contains eight 13-bit, voltage-output digital-toanalog converters (DACs). On-chip precision output amplifiers provide the voltage outputs. The MAX547 operates from a ±5V supply. Bipolar output voltages with up to ±4.5V voltage swing can be achieved with no external components. The MAX547 has four separate reference inputs; each is connected to two DACs, providing different fullscale output voltages for every DAC pair. The MAX547 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.
