MS5620 Datasheet | Ruimeng

DESCRIPTION The MS5620 is a quadruple, serial 8-bit voltage output digital-to-analog converter (DAC) featured by buffered reference inputs (high impedance). The output voltage range is from one or two times the reference voltage to GND and DAC is monotonic. The MS5620 is simple to use, because it operates in a single power supply, 3V to 5V. The power-up reset function can ensure repeatable start-up condition. Digital control is achieved by three-wire serial bus which is patible with CMOS and easily interfaced to microprocessor or microcontroller with industry standard. 11-bit mand word is consist of 8-bit data, 2-bit DAC channel select and 1-bit range control. The range control bit allows the output voltage between one or two times the reference voltage. The DAC has two-stage latches, allowing a plete set of data to be written to the device. Then LDAC controls all DAC outputs to update simultaneously . The digital input has Schmitt trigger with anti-noise ability. The small-outline package of the MS5620 enables the digital control of analog function to use in some applications which have strict demands for space. The MS5620 can operates from -40°C to 85°C and doesn’t need external trimming.
