Overview
EVALUATION KIT AVAILABLE MAX5800/MAX5801/MAX5802 Ultra-Small, Dual-Channel, 8-/10-/12-Bit Buffered Output DACs with Internal Reference and I2C Interface General Description The MAX5800/MAX5801/MAX5802 2-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 MAX5800/MAX5801/MAX5802 accept a wide supply voltage range of 2.
7V to 5.
5V with extremely low power (1.
5mW) consumption to accommodate most low-voltage applications.
A precision external reference input allows rail-to-rail operation and presents a 100kI (typ) load to an external reference.
The MAX5800/MAX5801/MAX5802 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 250FA per channel and a low offset error of Q0.
5mV (typ).
On power-up, the MAX5800/ MAX5801/MAX5802 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 MAX5800/MAX5801/ MAX5802 allow simultaneous output updates using software LOAD commands.
A clear logic input (CLR) allows the contents of the CODE and the DAC registers to be cleared asynchronously and sets the DAC outputs to zero.
The MAX5800/MAX5801/ MAX5802 are available in a small 10-pin µMAXM and an ultra-small, 10-pin TDFN package and are specified over the -40NC to +125NC temperature range.
