16 Bit Analog to Digital Converter 1 Input 1 SAR 28-SOIC

ADS8507IDW General Description

The ADS8507 is a complete low power, single 5-V supply, 16-bit sampling analog-to-digital (A/D) converter. It contains a complete 16-bit capacitor-based, successive approximation register (SAR) A/D converter with sample and hold, clock, reference, and data interface. The converter can be configured for a variety of input ranges including ±10 V, 4 V, and 5 V. For most input ranges, the input voltage can swing to 25 V or -25 V without damage to the converter.

A SPI compatible serial interface allows data to be synchronized to an internal or external clock. A full parallel interface with BYTE select is also provided to allow the maximum system design flexibility. The ADS8507 is specified at 40 kHz sampling rate over the industrial -40°C to 85°C temperature range.

as per description.All are working.excellent product

Very buggy, spend tree nights to get it working - but still unstable results.Camera is working as "Wrover", not as "AI Thinker" - from newest Arduino IDE.The seller did everything very fast, delivery time was less than two weeks to Moscow.So - I can recommend the seller - but not this camera (at least yet).I hope my experience may be help for somebody. ))
