Note 1: Due to leakage in the PGA and ADC, operation at sample rates below 1ksps is not recommended, as
performance may degrade, particularly at high temperatures.
Note 2: Production test equipment settling time prohibits leakage measurements below 1nA.
Lab equipment has shown the MAX1101 switch input leakage below 1pA at T_A = +25°C, and below 50pA at T_A = +70°C.
Note 3: Not a test parameter. Recommended for optimal performance.
