MAX5253ACPP

The MAX5253ACPP belongs to MAX5253 combines four low-power, voltage-output, 12-bit digital-to-analog converters (DACs)and four precision output amplifiers in a space-saving, 20-pin package. The serial interface is compatible with SPI?/QSPI and MICROWIRE?. 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 has a double-buffered input organized as an input register followed by a DAC register. A 16-bit serial word loads data into each input/DAC register. It allows the input and DAC registers to be updated independently or simultaneously with a single software command. The DAC registers can be simultaneously updated through the 3-wire serial interface. All logic inputs are TTL/CMOS-logic compatible. In addition to the four voltage outputs, each amplifier's negative input is also available to the user. This facilitates specific gain configurations, remote sensing, and high output drive capacity, making the MAX5253 ideal for industrial-process-control applications.

The features of MAX5253ACPP can be summarized as (1)four 12-Bit DACs with configurable output amplifiers; (2)+3.0V to +3.6V single-supply operation; (3)low supply current: 0.82mA normal operation 3A shutdown mode; (4)reference inputs are high impedance in shutdown; (5)available in 20-Pin SSOP; (6)power-on reset clears all registers and DACs to Zero; (7)SPI/QSPI and MICROWIRE Compatible; (8)simultaneous or independent control of DACs through 3-wire serial interface; (9)user-programmable digital output.
