Our customer is considering to use ADC081S021 but it requires a microcontroller interface to control CSnot. Is there something of an alternative that willcontinuously put out 8-bit words for the 0 to Vdd input voltage as it varies, without any uC control. In other words it has to sample the input, shoot out an 8-bit word over SPI and then sample the input again. Over and over until it powers down.
Single supply: Vdd = 4.5 to 5.5v, Fs = 50kHz minimum -> 1Mhz max, 8-bit words will go to a Microchip MCP41XXX to continuously vary the digital resistor.
Thanks and regards,
