ADS8513

ADS8513概述

具有 IR 和串行接口以及 TAG 的 16 位 40KSPS 低功耗采样 A/D 转换器

The is a complete low-power, single 5V 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, ±5V, 0V to 10V, and 0.5V to 4.5V. A high-impedance, 0.3V to 2.8V input is also available with input impedance greater than 10MΩ. For most input ranges, the input voltage can swing to 25V or -25V without damage to the converter.

An SPI-compatible serial interface allows data to be synchronized to an internal or external clock. The ADS8513 is specified at 40kSPS sampling rate over the industrial -40°C to +85°C temperature range.
