  16-Bit ADC Simplifies Current Measurements
  Design Note 341
  Mark Thoren
  Introduction
  The LTC®2433-1 is a high performance 16-bit Delta-Sigma ADC for DC measurements. With an input noise floor
  of 1.45ОјVRMS and a reference range of 100mV to VCC,
  the input resolution and range can be optimized for a
  wide variety of applications. The flexible SPI interface
  can be configured to self-clock, simplifying isolation
  or level shifting of digital signals in applications where
  the ADC must be referenced to a different potential than
  the data acquisition system. asynchronous communication schemes such as RS232.
  Unfortunately, the internal oscillator tolerance makes it
  risky to receive all 19 bits asynchronously. One solution
  is to apply a crystal-controlled clock signal to the FO
  pin, but there is a simpler (and cheaper) way. Data Transfer
  Figure 1a shows a –48V telecom supply current monitor
  with a 5.4A full scale. The LTC2433-1 serial interface is
  configured for internal serial clock, continuous conversion mode. This mode is selected by tying chip select
  low and pulling SCK high at power-up. In this mode,
  the LTC2433-1 continuously converts at 6.8 samples
  per second and clocks out its data at a serial data rate
  of 17.5kHz В±2%, the tolerance of the internal oscillator. While a conversion is taking place, both SCK and SDO …
