Ultra-Small, Quad-Channel, 8-/10-/12-Bit Buffered Output DACs with Internal Reference and SPI Interface

Feature-Rich, 4-Channel DAC Family Offered in a 3.5mm² WLP Footprint

Product Details

The MAX5713/MAX5714/MAX5715 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 MAX5713/MAX5714/MAX5715 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 MAX5713/MAX5714/MAX5715 have a 50MHz 3-wire SPI/QSPI/MICROWIRE®/DSP-compatible serial interface that also includes an active-low RDY output for daisy-chain applications. 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 MAX5713/MAX5714/MAX5715 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 MAX5713/MAX5714/MAX5715 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 MAX5713/MAX5714/MAX5715 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.

Description

Digital-to-analog converters (DACs) provide accurate output voltages for actuation and control in many electronic applications such as industrial, medical and RF systems. The MAX5715 is a highly accurate, four channel, 12-bit voltage output DAC. Development with DACs involves expertise in analog systems, power supplies, digital interfaces and firmware. Now, enter the MAX5715BOB to accelerate the development process.

The MAX5715BOB (Break Out Board) provides for rapid prototyping and development with the MAX5715 (a 12-bit, 4-channel, voltage-output DAC). MAX5715BOB interfaces to any Arduino™-compatible or mbed.org™ compatible platform system with expansion ports configurable for SPI communication. Additionally, the MAX5715BOB works with systems that have a Pmod™ connection, a 2 x 6 rightangle header at board edge (compatible with Digilentinc. com Pmod™ interface spec) Interface type 2A (expanded SPI) on 2x6 header at board edge. MAX5715BOB also comes with schematics, design files and firmware for immediate use and forking to future projects.
