7 General Operation Tables

The following section describes the general operation of the AMC1035EVM

CAUTION

Carefully review the AMC1035 product data sheet for the limitations of the analog input range and ensure that the appropriate analog/digital voltages are applied prior to connecting any analog input to the EVM.

Once the AMC1035EVM is supplied with power and an external clock, the digital outputs become active.

An analog input signal may be applied directly at screw terminal J2. Please see Figure 1 and Table 2 for details. The linear analog input range, AINP to AINN, is +/- 1 V and the full-scale range is +/-1.25 V.

As the input voltage approaches the maximum input level of +1 V, the 1s density of the modulator output will approach 90%. Likewise, when the input voltage approaches the lower limit of -1V the 1s density will be approximately 10%.
