Product Details
The MAX5500/MAX5501 integrate four low-power, 12-bit digital-to analog converters (DACs) and four precision output amplifiers in a small, 20-pin package. Each negative input of the four precision amplifiers is externally accessible providing flexibility in gain configurations, remote sensing, and high output drive capacity, making the MAX5500/MAX5501 ideal for industrial-process-control applications. Other features include software shutdown, hardware shutdown lockout, an active-low reset which clears all registers and DACs to zero, a user-programmable logic output, and a serial-data output.
Each DAC provides a double-buffered input organized as an input register followed by a DAC register. A 16-bit serial word loads data into each input register. The serial interface is compatible with SPI™/QSPI™/MICROWIRE™. The serial interface allows the input and DAC registers to be updated independently or simultaneously with a single software command. The 3-wire interface simultaneously updates the DAC registers. All logic inputs are TTL/CMOS-logic compatible. The MAX5500 operates from a single +5V power supply, and the MAX5501 operates from a single +3V power supply. The MAX5500/MAX5501 are specified over the extended -40°C to +105°C temperature range.
