The MAX5813/MAX5814/MAX5815 4-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 MAX5813/MAX5814/MAX5815 accept a wide supply voltage range of 2.7V to 5.5V with extremely low power (3mW) 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 MAX5813/MAX5814/MAX5815 have an I²C-compatible, 2-wire interface that operates at clock rates up to 400kHz. 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). On power-up, the MAX5813/ MAX5814/MAX5815 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 MAX5813/MAX5814/MAX5815 allow simultaneous output updates using software LOAD commands or the hardware load DAC logic input (active-low LDAC).

A clear logic input (active-low CLR) allows the contents of the CODE and the DAC registers to be cleared asynchronously and sets the DAC outputs to zero. The MAX5813/MAX5814/MAX5815 are available in a 14-pin TSSOP and an ultra-small, 12-bump WLP package and are specified over the -40°C to +125°C temperature range.

Product Detail

The MAX5815A evaluation kit (EV kit) demonstrates the MAX5815A 12-bit, 4-channel, low-power DAC with internal reference and buffered voltage output. The device is in a 14-pin TSSOP package. The EV kit provides controls to change the DAC's outputs, power operations, and references.
The EV kit includes a USB-to-I²C 400kHz interface circuit. The EV kit features Windows XP®-, Windows Vista®-, and Windows® 7-compatible software that provides a simple graphical user interface (GUI) for exercising the device features.
The EV kit comes with the MAX5815AAUD+ installed, which is the 12-bit I²C version. Contact the factory for samples of the pin-compatible MAX5815BAUD+ (12-bit), MAX5814AUD+ (10-bit), and MAX5813AUD+ (8-bit).
