MAX5158 - Low-Power / Dual / 10-Bit / Voltage-Output DACs

Description

The MAX5158/MAX5159 low-power, serial, voltageoutput, dual, 10-bit digital-to-analog converters (DACs) consume only 500µA from a single +5V (MAX5158) or +3V (MAX5159) supply.

These devices feature Rail-toRail® output swing and are available in a space-saving 16-pin QSOP package.

Features

  • include a 2µA programmable shutdown, 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. The MAX5158/MAX5159 provide a programmable logic pin for added functionality and a serial-data output pin for daisy chaining. ____________________________Features o 10-Bit Dual DAC with Internal Gain of +2V/V o Rail-to-Rail Output Swing o 8µs Settling Time o Single-Supply Ope.

19-1315; Rev 1; 12/97 Low-Power, Dual, 10-Bit, Voltage-Output DACs with Serial Interface MAX5158/MAX5159 _______________General Description The MAX5158/MAX5159 low-power, serial, voltageoutput, dual, 10-bit digital-to-analog converters (DACs) consume only 500µA from a single +5V (MAX5158) or +3V (MAX5159) supply. These devices feature Rail-toRail® output swing and are available in a space-saving 16-pin QSOP package. To maximize dynamic range, the DAC output amplifiers are configured with an internal gain of +2V/V. 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.
