The AD7537JNZ is a 12-bit current output monolithic Digital-to-analog Converter (DAC) with a separate reference input is provided. The dual DAC saves valuable board space and the monolithic construction ensures excellent thermal tracking. 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 low. To transfer this data to the DAC registers, UPD must be taken low with WR. Added features on the AD7537 include an asynchronous CLR line which is very useful in calibration routines. When this taken low, all registers are cleared. The double buffering of the data inputs allows simultaneous update of DAC. This increases the device versatility, for instance one DAC may be operated with AGND biased while the other is connected in the standard configuration. It is manufactured using the linear compatible CMOS process. It is speed compatible with most microprocessors and accepts TTL, 74HC and 5V CMOS logic level inputs.
