The benefits of 4-20mA current loop format in process control systems are 2-wire sensor operation, long cable runs, and noise immunity.  The voltages  for the loop can be ranging from 12VDC to 40VDC and  are inherently nonratiometric to the output signal. The MAX1452 low current consumption allows the system to operate from loop  power with a simple  4-20mA circuit drives. Here’s the circuit diagram:

The MAX1452 is equipped with five 16-bit internal calibration registers that can be loaded from the serial digital interface or from EEPROM. You can get more information about MAX1452 at http://datasheets.maxim-ic.com/en/ds/MAX1452.pdf .

This application note describe about ADC cycle latency, ADC latency time, and the delta-sigma analog-to-digital converter (ADC). The theory about ADC cycle latency, ADC latency time, and the delta-sigma analog-to-digital converter (ADC) are presented in detail after introduction.

The main topic is divided into 2 sections : ADC cycle latency and ADC latency time. The section ADC cycle latency contains about cycle latency for ADC. The description about latency time for ADC is explained in section ADC latency time.
