EVALUATION KIT AVAILABLE MAX5800/MAX5801/MAX5802 Ultra-Small, Dual-Channel, 8-/10-/12-Bit Buffered Output 2 DACs with Internal Reference and I C Interface General Description Benefits and Features The MAX5800/MAX5801/MAX5802 2-channel, low-power, S Two High-Accuracy DAC Channels 8-/10-/12-bit, voltage-output digital-to-analog converters 12-Bit Accuracy Without Adjustment (DACs) include output buffers and an internal reference 1 LSB INL Buffered Voltage Output that is selectable to be 2.048V, 2.500V, or 4.096V. The Monotonic Over All Operating Conditions MAX5800/MAX5801/MAX5802 accept a wide supply Independent Mode Settings for Each DAC voltage range of 2.7V to 5.5V with extremely low power S Three Precision Selectable Internal References (1.5mW) consumption to accommodate most low-voltage 2.048V, 2.500V, or 4.096V applications. A precision external reference input allows S Internal Output Buffer rail-to-rail operation and presents a 100kI (typ) load to Rail-to-Rail Operation with External Reference an external reference. 4.5s Settling Time 2 The MAX5800/MAX5801/MAX5802 have an I C-compatible, Outputs Directly Drive 2kI Loads 2-wire interface that operates at clock rates up to S Small 5mm x 3mm 10-Pin MAX or Ultra-Small 400kHz. The DAC output is buffered and has a low sup- 3mm x 3mm 10-Pin TDFN Package ply current of less than 250FA per channel and a low offset error of Q0.5mV (typ). On power-up, the MAX5800/ S Wide 2.7V to 5.5V Supply Range MAX5801/MAX5802 reset the DAC outputs to zero, pro- S Separate 1.8V to 5.5V V Power-Supply Input DDIO viding additional safety for applications that drive valves 2 S Fast 400kHz I C-Compatible, 2-Wire Serial or other transducers which need to be off on power-up. Interface The internal reference is initially powered down to allow S Power-On-Reset to Zero-Scale DAC Output use of an external reference. The MAX5800/MAX5801/ MAX5802 allow simultaneous output updates using soft- S CLR For Asynchronous Control ware LOAD commands. S Three Software-Selectable Power-Down Output A clear logic input (CLR) allows the contents of the CODE Impedances and the DAC registers to be cleared asynchronously and 1kI, 100kI, or High Impedance sets the DAC outputs to zero. The MAX5800/MAX5801/ S Low 350A Supply Current at 3V V DD MAX5802 are available in a small 10-pin MAXM and an ultra-small, 10-pin TDFN package and are specified over the -40NC to +125NC temperature range.
