MAX5705:Ultra-Small, Single-Channel, 8-/10-/12-Bit Buffered Output Voltage DACs with Internal Reference and SPI Interface

Feature-Rich, 1-Channel DAC Family

The MAX5703/MAX5704/MAX5705 single-channel, low-power, 8-/10-/12-bit, voltage-output digital-to-analog converters (DACs) include output buffers and an internal reference that is selectable to be 2.048V, 2.500V, or 4.096V. The MAX5703/MAX5704/MAX5705 accept a wide supply voltage range of 2.7V to 5.5V with extremely low power (< 1mW) 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. The MAX5703/MAX5704/MAX5705 have a 50MHz, 3-wire SPI/QSPI™/MICROWIRE®/DSP-compatible serial interface. The DAC output is buffered and has a low supply current of 155µA (typical at 3V) and a low offset error of ±0.5mV (typical). On power-up, the MAX5703/MAX5704/MAX5705 reset the DAC outputs to zero, providing additional safety for applications that drive valves or other transducers which need to be off on power-up. The internal reference is initially powered down to allow use of an external reference. The MAX5703/MAX5704/MAX5705 include a user-configurable active-low asynchronous input, AUX for additional flexibility. This input can be programmed to asynchronously clear (active-low CLR) or temporarily gate (active-low GATE) the DAC output to a user-programmable value. A dedicated asynchronous active-low LDAC input is also included. This allows simultaneous output updates of multiple devices. The MAX5703/MAX5704/MAX5705 are available in 10-pin TDFN/µMAX® packages and are specified over the -40°C to +125°C temperature range.
