MAX5725 12-Bit 8-Channel DACs

Analog Devices MAX5725 12-bit, 8-channel, Digital-to-Analog Converters (DACs) feature output buffers and an internal 3ppm/°C reference that is selectable at 2.048V, 2.500V, or 4.096V. MAX5725 accepts a wide supply voltage range of 2.7V to 5.5V with extremely low power (6mW) consumption to accommodate most low-voltage applications. A precision external reference input allows rail-to-rail operation and presents a 100kΩ (typ) load to an external reference. ADI MAX5725 DAC has a fast 50MHz, 4-wire SPI/QSPI™/MICROWIRE®/DSP-compatible serial interface that operates at clock rates up to 50MHz. The DAC output is buffered and has a low supply current of less than 250µA per channel and a low offset error of ±0.5mV (typ). The Analog Devices MAX5725 12-Bit 8-Channel DACs feature a programmable watchdog function that can be enabled to monitor the I/O interface for activity and integrity.
