Overview
19-4368; Rev 1; 4/09 MAX5500/MAX5501 Low-Power, Quad, 12-Bit Voltage-Output DACs with Serial Interface General Description 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.
Applications Industrial Process Controls Automatic Test Equipment Microprocessor (μP)-Controlled Systems Motion Control Digital Offset and Gain Adjustment Remote Industrial Controls Features o Four 12-Bit DACs with Configurable Output Amplifiers o +5V or +3V Single-Supply Operation o Low Supply Current: 0.
