19-1255; Rev 0; 8/97 Low-Power, Dual, 13-Bit Voltage-Output DACs with Serial Interface _______________General Description The MAX5150/MAX5151 low-power, serial, voltage-output, dual 13-bit digital-to-analog converters (DACs) consume only 500µA from a single +5V (MAX5150) or +3V (MAX5151) supply. These devices feature Rail-toRail® 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 .

19-1255; Rev 0; 8/97 Low-Power, Dual, 13-Bit Voltage-Output DACs with Serial Interface _______________General Description The MAX5150/MAX5151 low-power, serial, voltage-output, dual 13-bit digital-to-analog converters (DACs) consume only 500µA from a single +5V (MAX5150) or +3V (MAX5151) supply. These devices feature Rail-toRail® 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 doublebuffered input organized as an input register followed by a DAC register, which allows the input and DAC registers 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 activelow 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. ____________________________Features o o o o o o o o o 13-Bit Dual DAC with Internal Gain of +2 Rail-to-Rail Output Swing 16µs Settling Time Single-Supply Operation: +5V (MAX5150) +3V (MAX5151) Low Quiescent Current: 500µA (normal operation) 2µA (shutdown mode) SPI/QSPI and Microwire Compatible Available in Space-Saving 16-Pin QSOP Package Power-On Reset Clears Registers and DACs to Zero Adjustable Output Offset MAX5150/MAX5151 ______________Ordering Information PART MAX5150ACPE MAX5150BCPE MAX5150ACEE MAX5150BCEE MAX5150BC/D TEMP.
