Advanced Linear Devices ALD500
The ALD500AU/ALD500A/ALD500 are integrating dual slope analog processors, designed to operate on ±5V power supplies for building precision analog-to-digital converters. The ALD500AU/ALD500A/ ALD500 feature specifications suitable for 18 bit/17 bit/16 bit resolution conversion, respectively. The digital controller can be implemented by an external microcontroller, under either hardware (fixed logic) or software control.APPLICATIONS
