MCP3221A2T-I/OT中文资料微芯科技数据手册PDF规格书

描述 Description

The Microchip Technology Inc. MCP3221 is a successive approximation A/D converter with 12-bit resolution. Available in the SOT-23 package, this device provides one single-ended input with very low power consumption. Based on an advanced CMOS technology, the MCP3221 provides a low maximum conversion current and standby current of 250 µA and 1 µA, respectively. Low current consumption, combined with the small SOT-23 package, make this device ideal for battery-powered and remote data acquisition applications.
