ADC10154 - 具有 4 或 8 通道 MUX、跟踪/保持和参考功能的 10 位 + 4 微秒 ADC - 精密ADC(<=10MSPS) - 模数转换器 - TI公司（Texas Instruments，德州仪器）
The ADC10154 and ADC10158 are CMOS 10-bit plus sign successive approximation A/D converters with versatile analog input multiplexers, track/hold function and a 2.5V band-gap reference. The 4-channel or 8-channel multiplexers can be software configured for single-ended, differential or pseudo-differential modes of operation.
The input track/hold is implemented using a capacitive array and sampled-data comparator.
Resolution can be programmed to be 8-bit, 8-bit plus sign, 10-bit or 10-bit plus sign. Lower-resolution conversions can be performed faster.
The variable resolution output data word is read in two bytes, and can be formatted left justified or right justified, high byte first.
