Description

The MAX5510/MAX5511 are single, 8-bit, ultra-low-power, voltage-output, digital-to-analog converters(DACs) offering Rail-to-Rail®buffered voltage outputs.The DACs operate from a 1.8V to 5.5V supply and con-sume less than 6µA, making them desirable for low-power and low-voltage applications. A shutdown modereduces overall current, including the reference inputcurrent, to just 0.18µA. The MAX5510/MAX5511 use a3-wire serial interface that is compatible with SPI™,QSPI™, and MICROWIRE™.

At power-up, the MAX5510/MAX5511 outputs are dri-ven to zero scale, providing additional safety for appli-cations that drive valves or for other transducers thatmust be off during power-up. The zero-scale outputsenable glitch-free power-up.

The MAX5510 accepts an external reference input. TheMAX5511 contains an internal reference and providesan external reference output. Both devices have force-sense-configured output buffers.

The MAX5510/MAX5511 are available in a 4mm x 4mmx 0.8mm, 12-pin, thin QFN package and are guaranteedover the extended -40°C to +85°C temperature range.For 12-bit compatible devices, refer to the MAX5530/MAX5531 data sheet. For 10-bit compatible devices,refer to the MAX5520/MAX5521 data sheet.
