Richardson RFPD Converter - DAC AD5360BSTZ

The AD5360/AD5361 contain sixteen, 16-/14-bit DACs in a single 52-lead LQFP or 56-lead LFCSP package. They provide buffered voltage outputs with a span four times the reference voltage. The gain and offset of each DAC can be independently trimmed to remove errors. For even greater flexibility, the device is divided into two groups of eight DACs, and the output range of each group can be independently adjusted by an offset DAC. The AD5360/AD5361 offer guaranteed operation over a wide supply range with VSS from -4.5 V to -16.5 V and VDD from +8 V to +16.5 V. The output amplifier headroom requirement is 1.4 V. The AD5360/AD5361 have a high speed 4-wire serial interface, which is compatible with SPI, QSPI™, MICROWIRE™, and DSP interface standards and can handle clock speeds of up to 50 MHz. All the outputs can be updated simultaneously by taking the LDAC input low. Each channel has a programmable gain register and an offset adjust register. Each DAC output is amplified and buffered on-chip with respect to an external SIGGNDx input. The DAC outputs can also be switched to SIGGNDx via the CLR pin.
