CBM128S085 12 bits，low-power，8 channels analog-to-digital converter with rail to rail output

CBM128S085/CBM108S085 is a high-precision and highly integrated digital to analog converter chip. A single chip integrates an 8-channel 12 / 10-bit voltage output digital to analog converter with output buffer drive. The chip is packaged with a smaller 16-pin TSSOP; The normal operational power supply voltage range is 2.7V ~ 5.5V; The output buffer drive can ensure that the output voltage is rail to rail, so as to ensure the maximum voltage output range; The power consumption is very low. Without load, the overall consumed current is only 540uA@3V ，600uA@5V. The three-wire serial interface is adopted, and the maximum clock can reach 40MHz. It allows very flexible configuration and is compatible with the current common SPI ™, QSPI, MICROWIRE, DSP and other interface standards. It supports daisy chain working mode. A single interface can control multiple chips at the same time to ensure that multiple chips update their status at the same time. CBM128S085/CBM108S085 have two external reference voltage inputs, one for channels A to D and the other for channels E to H. Each reference voltage can be configured separately, allowing the input range to be 0.5V ~ VA, so as to ensure that the chip provides the widest possible dynamic output range. The 16 shift registers at the digital input controlled by the serial interface can easily control the working mode of the chip, including sleep output state and output update state. All channels can be updated individually or uniformly.The biggest feature of CBM128S085/CBM108S085 is that it supports both power on reset and power-off reset. The power on reset circuit ensures that when the power supply voltage rises to the effective voltage, the output of the digital to analog converter is 0V and remains in this state until a new state update command is received. When the chip power supply voltage drops below 2.7V, the power-off reset circuit resets the chip so that the output of the digital to analog converter is 0V, so as to avoid the impact of the non-0V output voltage of th
