ADS8513IDWRG4

模数转换器 - ADC 16B 40KSPS Lo Pwr Sampling ADC

DESCRIPON

The ADS8513 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 serial data interface. The converter

can be configured for a variety of input ranges including ±10 V, ±5 V, 0 V to 10 V, and 0.5 V to

4.5 V. A high-impedance, 0.3-V to 2.8-V input is also available with input impedance greater than 10 MΩ. For most input ranges, the input voltage can swing to 25 V or –25 V without damage to the converter.
