SGM51242R2/4/8数据手册SGMICRO中文资料规格书

描述 Description

The SGM51242R2, SGM51242R4, and SGM51242R8 are 12-bit ADCs, which have an analog multiplexer of 2-channel/4-channel/8-channel input, respectively. The input range of the ADC is 0V to VREF or 0V to 2 × VREF. The ADC has a total throughput rate of 250kSPS.

The SGM51242R2, SGM51242R4, and SGM51242R8 have an integrated 2.5V, 10ppm/℃ (TYP) reference, which is turned off by default, and an integrated temperature sensor, which gives an indication of the die temperature. The temperature value is read back as part of an ADC read sequence.

The SGM51242R2 is available in a Green TQFN-3×3-16BL. The SGM51242R4 and SGM51242R8 are available in Green TQFN-3×3-16BL and TSSOP-16 packages. They operate over an ambient temperature range of -40℃ to +125℃.
