MAX5500/MAX5501 19-4368 Rev 1 4/09 Low-Power, Quad, 12-Bit Voltage-Output DACs with Serial Interface General Description Features Four 12-Bit DACs with Configurable Output The MAX5500/MAX5501 integrate four low-power, 12-bit Amplifiers digital-to analog converters (DACs) and four precision output amplifiers in a small, 20-pin package. Each nega- +5V or +3V Single-Supply Operation tive input of the four precision amplifiers is externally Low Supply Current: accessible providing flexibility in gain configurations, 0.85mA Normal Operation remote sensing, and high output drive capacity, making 10A Shutdown Mode (MAX5500) the MAX5500/MAX5501 ideal for industrial-process-con- Force-Sense Outputs trol applications. Other features include software shut- Power-On Reset Clears All Registers and DACs down, hardware shutdown lockout, an active-low reset to Zero which clears all registers and DACs to zero, a user-pro- Capable of Recalling Last State Prior to Shutdown grammable logic output, and a serial-data output. SPI/QSPI/MICROWIRE Compatible Each DAC provides a double-buffered input organized Simultaneous or Independent Control of DACs as an input register followed by a DAC register. A 16-bit through 3-Wire Serial Interface serial word loads data into each input register. The seri- User-Programmable Digital Output al interface is compatible with SPI/QSPI/ MICROWIRE. The serial interface allows the input and Guaranteed Over Extended Temperature Range DAC registers to be updated independently or simulta- (-40C to +105C) neously with a single software command. The 3-wire Ordering Information interface simultaneously updates the DAC registers. All logic inputs are TTL/CMOS-logic compatible. The PIN- MAX5500 operates from a single +5V power supply, PART INL (LSB) SUPPLY (V) PACKAGE and the MAX5501 operates from a single +3V power supply. The MAX5500/MAX5501 are specified over the MAX5500AGAP+ 20 SSOP 0.75 +5 extended -40C to +105C temperature range.
