MAX5804
Description
The MAX5803/MAX5804/MAX5805 single-channel, lowpower, 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 MAX5803/MAX5804/MAX5805 accept a wide supply voltage range of 2.7V to 5.5V with extremely low power (< 1m W) consumption to acmodate most low-voltage applications. A precision external reference input allows rail-to-rail operation and presents a 100k I (typ) load to an external reference. The MAX5803/MAX5804/MAX5805 have an I 2Cpatible, 2-wire interface that operates at clock rates up to 400k Hz. The DAC output is buffered and has a low supply current of 155FA (typical at 3V) and a low offset error of Q0.5m V (typical). On power-up, the MAX5803/MAX5804/MAX5805 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...
