Low-Power, Multi-Channel, Serial 8-Bit ADCs _______________Detailed Description The MAX1112/MAX1113 analog-to-digital converters (ADCs) use a successive-approximation conversion technique and input track/hold (T/H) circuitry to convert an analog signal to an 8-bit digital output. A flexible seri- al interface provides easy ...

Low-Power, Multi-Channel, Serial 8-Bit ADCs The time required for the T/H to acquire an input signal is a function of how quickly its input capacitance is charged. If the input signal’s source impedance is high, the acquisition time lengthens, ...
