... Pin Compatible Upgrade to LTC 1298 DESCRIPTION The SP8538 is a very low power 12-Bit data acquisition chip. The SP8538 typically draws 250 A of supply current when sampling at 25 kHz. Supply current drops linearly as the sample rate is reduced. The ADC automatically powers down when not performing conversions, drawing only leakage current ...

... MSB through LSB, with MSBF set to zero the output data stream will be MSB through LSB followed by the same data in LSB through MSB format. The SP8538 is a SAR converter with full differential multiplexed front end, capacitive DAC, precision comparator, Successive Approximations Register, control logic and data output register ...

... Parallel analog and digital lines should be separated by a circuit board trace which is connected to common. The SP8538 VCC pin is also the reference pin for the device. This means that noise on the VCC pin will be proportionally represented as noise in the converters output data. A noise signal of 1 ...
