Product Summary

The AD7811YRUZ is a high speed, low power, 10-bit A/D converter that operates from a single 2.7 V to 5.5 V supply. The AD7811YRUZ contains a 2.3 μs successive approximation A/D converter, an on-chip track/hold amplifier, a 2.5 V on-chip reference and a high speed serial interface that is compatible with the serial interfaces of most DSPs (Digital Signal Processors) and microcontrollers. The user also has the option of using an external reference by connecting it to the VREF pin and setting the EXTREF bit in the control register.
