1 / 16 page _______________General Description The MAX5150/MAX5151 low-power, serial, voltage-out- put, dual 13-bit digital-to-analog converters (DACs) consume only 500µA from a single +5V (MAX5150) or +3V (MAX5151) supply. These devices feature Rail-to- Rail® output swing and are available in a space-saving 16-pin QSOP package. To maximize the dynamic range, the DAC output amplifiers are configured with an internal gain of +2. The 3-wire serial interface is SPI™/QSPI™ and Microwire™ compatible. Each DAC has a double- buffered input organized as an input register followed by a DAC register, which allows the input and DAC reg- isters to be updated independently or simultaneously with a 16-bit serial word. Additional features include programmable shutdown (2µA), hardware-shutdown lockout, a separate reference voltage input for each DAC that accepts AC and DC signals, and an active- low clear input (CL) that resets all registers and DACs to zero. These devices provide a programmable logic pin for added functionality, and a serial-data output pin for daisy-chaining. ________________________Applications Industrial Process Control Remote Industrial Controls Digital Offset and Gain Microprocessor- Adjustment Controlled Systems Motion Control Automatic Test Equipment (ATE) ____________________________Features o 13-Bit Dual DAC with Internal Gain of +2 o Rail-to-Rail Output Swing o 16µs Settling Time o Single-Supply Operation: +5V (MAX5150) +3V (MAX5151) o Low Quiescent Current: 500µA (normal operation) 2µA (shutdown mode) o SPI/QSPI and Microwire Compatible o Available in Space-Saving 16-Pin QSOP Package o Power-On Reset Clears Registers and DACs to Zero o Adjustable Output Offset Low-Power, Dual, 13-Bit Voltage-Output DACs with Serial Interface ________________________________________________________________ Maxim Integrated Products 1 19-1255; Rev 0; 8/97 ______________Ordering Information Rail-to-Rail is a registered trademark of Nippon Motorola Ltd.
