  • The RHFAD128 is specifically designed to sustain ionizing dose and heavy-ions for space applications by using a high-end proven CMOS technology.

    This device is a low-power, multiplexed eight-channel 12-bit analog-to-digital converter for conversion from 50 ksps to 1 Msps. The architecture is based on the successive-approximation register with internal track-and-hold. The RHFAD128 features 8 analog inputs which can be programmed to be either 8-single ended or 4 differential inputs using the control register bits. The output serial data are straight binary and are compatible with SPI™.
    The analog and digital power supplies operate from 2.7 V to 3.6 V, drawing a current consumption of 1.65 mA typ. and 2 mA max. only.
    The RHFAD128 is in hermetic ceramic Flat-16 leads, and works from  -55 °C to + 125 °C  ambient temperature.

    Key Features

    • 50 ksps to 1 Msps conversion rate
    • 8-to-1-channel single input MUX
    • 4-to-1-channel differential input MUX
