DAC7621E/1KG4 DESCRIPTION

The DAC7621 is a 12-bit digital-to-analog converter(DAC) with guaranteed 12-bit monotonicity perfor-mance over the industrial temperature range. It re-quires a single +5V supply and contains an inputregister, latch, 2.435V reference, DAC, and high speedrail-to-rail output amplifier. For a full-scale step, theoutput will settle to 1 LSB within 7m s. The deviceconsumes 2.5mW (0.5mA at 5V).The parallel interface is compatible with a wide varietyof microcontrollers. The DAC7621 accepts a 12-bitparallel word, has a double-buffered input logic struc-ture and provides data readback. In addition, twocontrol pins provide a chip select (CS) function andasynchronous clear (CLR) input. The CLR input canbe used to ensure that the DAC7621 output is 0V onpower-up or as required by the application.The DAC7621 is available in a 20-lead SSOP packageand is fully specified over the industrial temperaturerange of –40(cid:176) C to +85(cid:176) C.SBAS107
