AD5370:  40-Channel, 16-Bit, Serial Input, Voltage-Output DACs

Product Description

The AD5370* contains forty 16-bit DACs in a single 64-lead LFCSP and a 64-lead LQFP. The device provides buffered voltage outputs with a span that is 4× the reference voltage. The gain and offset of each DAC channel can be independently trimmed to remove errors. For even greater flexibility, the device is divided into five groups of eight DACs. Three offset DAC channels allow the output range of blocks to be adjusted. Group 0 can be adjusted by Offset DAC 0, Group 1 can be adjusted by Offset DAC 1, and Group 2 to Group 4 can be adjusted by Offset DAC 2.

The AD5370 offers guaranteed operation over a wide supply range, with VSS from −16.5 V to −4.5 V and VDD from +9 V to +16.5 V. The output amplifier headroom requirement is 1.4 V operating with a load current of 1 mA.

The AD5370 has a high speed serial interface that is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards and can handle clock speeds of up to 50 MHz.

The DAC registers are updated on receipt of new data. All the outputs can be updated simultaneously by taking the LDAC input low. Each channel has a programmable gain and an offset adjust register to allow removal of gain and offset errors.

Each DAC output is gained and buffered on chip with respect to an external SIGGNDx input. The DAC outputs can also be switched to SIGGNDx via the CLR pin.
