  • CMS24AD2001

    CMS24AD2001 is a high-precision, low-power analog-to-digital conversion chip. It can support two differential input channels, with a built-in linear regulator (LDO), temperature sensor and high-precision oscillator. LDO can drive 20mA load. The PGA magnification of CMS24AD2001 is optional: 1, 2, 4, 8, 16, 32, 64, 128, 256. The ADC data output rate of CMS24AD2001 in normal mode is optional: 2.5Hz-2.56KHz, the default is 5Hz.


    Datasheet >

    CMS24AD2001 adopts Sigma-Delta modulator and realizes PGA amplification through low-noise instrument amplifier structure. When PGA=128, ODR=10Hz, VREF=3.3V, the effective resolution can reach 20.6 bits. CMS24AD2001 has a built-in RC oscillator, which can be used to configure multiple functional modes through DRDYB/DOUT and SCLK, such as temperature detection, PGA gain selection, ADC data output rate selection, and so on.
