FUNCTIONAL BLOCK DIAGRAM
GENERAL DESCRIPTION
The AD7537 contains two 12-bit current output DACs on one monolithic chip. A separate reference input is provided for each DAC. The dual DAC saves valuable board space, and the monolithic construction ensures excellent thermal tracking. Both DACs are guaranteed 12-bit monotonic over the full temperature range. The AD7537 has a 2-byte (8 LSBs, 4 MSBs) loading structure. It is designed for right-justified data format. The control signals for register loading are A0, A1, CS, WR and UPD. Data is loaded to the input registers when CS and WR are...
