ADC10154/ADC10158 10-Bit Plus Sign 4 µs ADCs with 4- or 8-Channel MUX, Track/Hold and Reference
November 1999
ADC10154/ADC10158 10-Bit Plus Sign 4 µs ADCs with 4- or 8-Channel MUX, Track/Hold and Reference
General Description
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.
