Maxim MAX5813-15 Quad-Channel 8/10/12-bit DACs

Maxim MAX5813/14/15 Quad-Channel 8/10/12-bit DACs

Maxim 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, 2.5V, or 4.096V. These Maxim DACs 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. 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 (typical). On power-up, the DAC outputs are reset 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. Theses Maxim devices also allow simultaneous output updates using software LOAD commands or the hardware load DAC logic input (active-low LDAC). MAX5813 / MAX5814 / MAX5815 are ideal for use in a variety of applications, including programmable voltage and current sources, gain and offset adjustment, automatic tuning and optical control, and more.
