16-Bit ADC Simplifies Current Measurements
Design Note 341

Introduction
The LTCВ®2433-1 is a high performance 16-bit Delta-Sigma ADC for DC measurements. With an input noise п¬‚oor
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 п¬‚exible SPI interface
can be conп¬Ѓgured 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 вЂ“48V telecom supply current monitor
with a 5.4A full scale. The LTC2433-1 serial interface is
conп¬Ѓgured 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 …
