16-bit SAR ADC with 40 kS/s — the industrial workhorse
It carries both SPI and parallel data interfaces, so it can drop onto an MCU's memory bus for fast reads or connect via a serial port to save pins. The internal reference and S/H circuit keep the external BOM lean — just a 5 V supply for both analog and digital rails and a handful of decoupling caps.
The 5 V-only supply rail is common in existing 5 V PLC analog input modules, so a board spin using this part doesn't require a new regulator.
Package and rework
The 28-SOIC (0.295-inch body width, 7.50 mm) is a wide-body SOIC. It handles hot-air rework well — the leads are exposed, so you can wet them with flux and lift the part without cooking the board.
