General Description

The MAX5803/MAX5804/MAX5805 single-channel, low-power, 8-/10-/12-bit, voltage-output this is an addition to content 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 (
